1 x 10⁻⁹ expresses a very small number i.e. nanosecond using a negative power of 10. The correct answer is option b).
Computer calculation speeds are incredibly fast, and they are usually measured in very small units of time. One of these units is a nanosecond, which is equal to one billionth of a second, or 0.000000001 seconds. This unit is used to measure the time it takes for a computer to perform basic operations such as adding two numbers or accessing data from memory.
To express 0.000000001 in scientific notation using a negative power of 10, we need to determine the number of decimal places to the right of the decimal point until we reach the first non-zero digit. In this case, we count nine decimal places to the right of the decimal point before we reach the first non-zero digit, which is 1. This means that 0.000000001 can be written as 1 x 10⁻⁹.
In scientific notation, any number can be expressed as the product of a number between 1 and 10, and a power of 10. The power of 10 tells us how many places we need to move the decimal point to the left or right to express the number in standard form. In the case of 0.000000001, we need to move the decimal point nine places to the right to express the number in standard form.
By writing this number in scientific notation as 1 x 10⁻⁹, we can easily perform calculations with it and compare it to other values measured in nanoseconds. Hence option b) is the correct option.

A plane leaves Singapore airport at 07:45 to fly to Sydney. The plane flies at an average speed of 757.2 km/h. The distance from Singapore to Sydney is 6310 km. The time in Sydney is 2 hours ahead of Singapore time. Calculate the local time when the plane arrives in Sydney. Give your answer in the form hours:minutes using the 24-hour clock.
The local time in Sydney when the plane arrives will be 18:58, or 6:58 PM on a 24-hour clock.
How to find arrival time for the plane?The time difference between Speed and Sydney is 2 hours, and the plane will take some time to fly from Singapore to Sydney at an Speed of 757.2 km/h over a distance of 6310 km.
The time it takes the plane to fly from Speed to Sydney can be calculated as:
time = distance / Speed= 6310 km / 757.2 km/h = 8.33Speed
So the plane will take 8.33 hours to fly from Singapore toSpeed
Now we need to add the 2-hour time difference between Singapore and Sydney to determine the local time in Sydney when the plane arrives.
07:45 (Singapore time) + 8.33 hours (flight time) + 2 hours (time difference) = 18:58
Therefore, the local time in Sydney when the plane arrives will be 18:58, or 6:58 PM on a 24-hour clock.

1. The price of 32'' LED television is P15,500 less than twice the price of the
old model. If it cost P29,078. 00 to buy a new 32'' LED television, what is
the price of the old model?
2. The perimeter of the rectangle is 96 when the length of a rectangle is
twice the width. What are the dimensions of therectangle?
The price of the old model is given by $22.289 and dimensions of the rectangle by 16units and 32 units.
Two dimensions make up a rectangle: the length and, perpendicular to that, the breadth. A triangle's or an oval's interior likewise has two dimensions. Despite the fact that we don't consider them to have "length" or "height," they do span a territory that is expansive in more than one way.
A circle can be measured in any direction. Why do we just consider it to be two dimensional? Because only one direction—the direction perpendicular to the first measurement—can be used to make a second measurement, for a total of two directions.
Let us assume that, price of the old model is Px .
so,
→ Price of 32" LED television = P(2x - 15.500)
A/q,
→ (2x - 15.500) = 29.078
→ 2x = 29.078 + 15.500
→ 2x = 44.578
→ x = $22.289
Therefore, price of the old model is $22.289.
Let us assume that, width of the rectangle is x unit.
so,
→ Length = twice of width = 2x = 2x unit .
then,
→ Perimeter = 2(Length + width)
A/q,
→ 2(2x + x) = 96
→ 3x = 48
→ x = 16 unit .
therefore,
Width of rectangle = x = 16 units .
Length of rectangle = 2x = 32 units.
Hence, the dimensions of the rectangle are 16units and 32 units.

EXAMPLE 1 A spring with a mass of 6 kg has a natural length of 0.3 m. A force of 38.4 N is required to maintain it stretched to a length of 0.7 m. If the spring is stretched to a length of 0.7 m and then released with initial velocity 0, find the position of the mass at time t. SOLUTION From Hooke's Law, the force required to stretch the spring is k(0.4) = 38.4 so k = 38.4/0.4 = 96. Using this value of the spring constant k, together with m = 6, we have d²x 6 = 0. + dt2 As in the earlier general discussion, the solution of this equation is X(t) = ( cos(4t) + C2 sin(4t). We are given the initial condition that x(0) = 0.4. But, from the previous equation, x(0) = cz. Therefore cn = . Differentiating, we get x'(t) = -4c sin(4t) + 4c2 cos(4t). Since the initial velocity is given as x'(O) = 0, we have cz = 0 and so the solution is = x(t) =
The equation given in the solution is X(t) = (cos(4t) + C2sin(4t)). This equation represents the position of the mass at time t after the spring has been released with an initial velocity of 0. The terms "spring" and "stretch" indicate that Hooke's Law is being used to determine the spring constant k.
The term "velocity" is used to describe the initial velocity of the mass, which is given as 0. The position of the mass at time t is determined by the value of X(t), which is a function of time. Therefore, the position of the mass at any given time can be found by plugging in the value of t into the equation X(t) = (cos(4t) + C2sin(4t)).
Hi! Based on the information provided, you have a spring with a mass of 6 kg and a natural length of 0.3 m. A force of 38.4 N is required to stretch it to 0.7 m. The spring constant, k, is determined to be 96. The spring is then stretched to 0.7 m and released with an initial velocity of 0. To find the position of the mass at time t, you can use the equation:
x(t) = C1 * cos(4t) + C2 * sin(4t)
Given the initial condition x(0) = 0.4, we find that C1 = 0.4. The initial velocity x'(0) is 0, leading to the conclusion that C2 = 0. Therefore, the equation for the position of the mass at time t is:
x(t) = 0.4 * cos(4t)

The diameter of a sphere measures 10. 4 inches. What is the surface area of the sphere?
The Surface Area of the sphere is approximately 339.79 square inches.
The surface area of a sphere is given by the formula:
surface area= [tex]4\pi r^{2}[/tex]
where r is the radius of the sphere.
The diameter of the sphere measures 10.4 inches, hence the radius can be calculated as:
r=10.4/2=5.2inches
Hence, the surface area can be calculated as by substituting r=5.2 inches
Therefore, surface area of the sphere is:
Surface Area = [tex]4\pi (5.2)^{2}[/tex]=[tex]4\pi (27.04)[/tex]= 108.16[tex]\pi[/tex] square inches.

(a) if f(4) = 6, what is f-|(6)? f-'(6) = (b) Suppose a function can be described by y = f(x). The function and its inverse intersect when y = (c) Consider a linear function f (x) = ax + b where a 70. Is the inverse of this linear function always a linear function? (No answer given) If f(x) = ax + b and a € 0, then f-'(x) =
To find f-1(6), we need to find the value of x that gives f(x) = 6. However, we don't have enough information about the function f to do this. We need to know whether f is a linear function or not.
When the function and its inverse intersect, we have f(x) = f-1(x). Substituting y for both f(x) and f-1(x), we get y = f(y). To find the value of y when this is true, we need to solve for y:
y = f(y)
y = f-1(y)
Substituting y = f(x), we get:
f(x) = f-1(f(x))
f(x) = x
So the function and its inverse intersect when y = x.
If a = 0, then the linear function is f(x) = b, which is a constant function. Constant functions do not have inverses, so the inverse of f(x) = b does not exist.
If a ≠ 0, then the inverse of f(x) = ax + b is given by:
f-'(x) = (x - b) / a
This is also a linear function, so the inverse of a linear function is always a linear function when a ≠ 0.
(a) To find the inverse of a linear function, you need to swap the x and y values. Given that f(4) = 6, the inverse function f^(-1)(6) would yield the value of x when y = 6. Since we know that f(4) = 6, it implies that f^(-1)(6) = 4.
A function and its inverse intersect when the input value (x) is equal to the output value (y). In other words, they intersect when y = x.
(c) Yes, the inverse of a linear function is always a linear function. If f(x) = ax + b, where a ≠ 0, then the inverse function, f^(-1)(x), can be found by swapping x and y values and solving for y. In this case, x = ay + b. Solving for y, we get y = (x - b) / a, which is also a linear function.

In Year 6 at Woodland Junior School, there are 90 children split into three classes of 14, 24, and 12 on the basis of there selection of sports. In 6M, 14 not chose hockey, and the rest of the class was split equally between football and netball. In 6P, 24 not chose netball, 16 chose football, and 8 choose hockey In 6T, the ratio of football to netball to hockey was 1:2:3. The completed table is shown.
To complete the table, we need to distribute the remaining children who did not choose their sport in each class. Here's how we can calculate it
In 6M, the number of children who did not choose hockey is 27 - 13 = 14.
Since the rest of the class was split equally between football and netball, each of these two sports will have 14/2 = 7 children.
In 6P, the number of children who did not choose netball is 33 - 9 = 24.
Since twice as many children chose football as chose hockey, we can write the number of footballers as 2x, and the number of hockey players as x. Then we have 2x + x + 9 = 33, which gives x = 8. Therefore, we have 16 children who chose football, and 8 children who chose hockey. The number of children who did not choose any of these two sports is 33 - 16 - 8 - 9 = 0.
In 6T, the ratio of children who chose football to netball to hockey was 1:2:3. Let's call the number of children who chose netball as 2x, and the number of children who chose hockey as 3x. Then we have x + 2x + 3x = 30, which gives x = 6. Therefore, we have 6 children who chose football, 12 children who chose netball, and 18 children who chose hockey.

The solution set for the equation 1/2 = 1/3 - |(x-3/6)+x| is {1/12, -1/12}.
How to Solve Absolute Value Equations?To solve the equation 1/2 = 1/3 - |(x-3/6)+x|, we need to isolate the absolute value expression and solve for x in two cases.
Case 1: (x-3/6)+x is nonnegative, which means the absolute value can be removed.
1/2 = 1/3 - (x-3/6)-x
1/2 = 1/3 - 2x + 1/2
2x = 1/6
x = 1/12
Case 2: (x-3/6)+x is negative, which means the absolute value must be flipped.
1/2 = 1/3 + (x-3/6)+x
1/2 = 1/3 + 2x - 1/2
2x = -1/6
x = -1/12

Mario's Pizzeria offers 2 types of crust and 6 different kinds of toppings. They assigned each side of the coin to a type of pizza crust and each number on the number cube to a topping. If Mario's makes a one-topping pizza, what is the probability that the coin flipped and the cube rolled will describe the pizza crust and topping combination they just made? Express the answer as a decimal rounded to the nearest thousandth
To determine the probability of the coin flip and the cube roll describing the pizza crust and topping combination made at Mario's Pizzeria, we need to consider the total possible outcomes of these events.
There are 2 types of crust, so the coin has 2 sides (heads for one crust type and tails for the other). For the toppings, there are 6 options, represented by the numbers 1 to 6 on the number cube.
First, we find the total possible outcomes by multiplying the number of crust options (2) by the number of topping options (6):
Total possible outcomes = 2 crust options * 6 topping options = 12 combinations
Since there is only one specific combination that Mario's Pizzeria just made, the probability of the coin flip and the cube roll describing this specific combination is:
Probability = 1 (specific combination) / 12 (total possible outcomes)
To express this as a decimal rounded to the nearest thousandth, divide 1 by 12:
Probability ≈ 0.083
So, the probability that the coin flipped and the cube rolled will describe the pizza crust and topping combination that Mario's Pizzeria just made is approximately 0.083, or 8.3%.

D. 20
If Juan does not read any books before day 4 and he starts reading at the same rate as Patti for the rest of the month, he would have read 6 books by day 12. The correct option is A.
If Juan does not read any books before day 4, it means he has missed out on the opportunity to read for the first three days. Assuming Patti and Juan have been reading at the same rate since day 4, we can calculate the total number of books they would have read by day 12.
Patti reads one book per day, so by day 12, she would have read a total of 9 books (from day 4 to day 12). If Juan starts reading at the same rate as Patti from day 4, he would also have read 9 books by day 12.
However, we have to account for the fact that Juan did not read any books before day 4. This means that he missed out on the opportunity to read 3 books (one book per day for the first three days). Therefore, by day 12, Juan would have read a total of 6 books (3 books missed + 3 books read from day 4 to day 12).
Therefore, the answer is A. Juan would have read 5 books less than Patti by day 12, since Patti would have read a total of 9 books and Juan would have only read 6.

Find the area of the regular polygon with the given apothem a and side length s.
pentagon, a = 10. 4 cm, s = 15. 1 cm
The area of the regular pentagon is approximately 392.2 square centimeters.
The area of a regular polygon can be calculated using the formula:
A = (1/2) * apothem * perimeter
where perimeter = number of sides * side length.
For a pentagon with side length s = 15.1 cm, the perimeter is:
perimeter = 5 * 15.1 = 75.5 cm
The apothem is a = 10.4 cm.
Using the formula, we get:

A cylinder and a cone have the same volume. The cylinder has radius x
and height y
. The cone has radius 2x
. Find the height of the cone in terms of y
.
The height of the cone in terms of y is h = y / 4.
How to find the volume of a cone and a cylinder?The cylinder and the cone have the same volume. The cylinder has radius x and height y. The cone has radius 2x.
Therefore,
volume of a cylinder = πr²h
where
r = radiush = heightVolume of a cone = 1 / 3 πr²h
where
r = radiush = heightTherefore,
πr²h = 1 / 3 πr²h
πx²y = 1 / 3 π (2x)²h
πx²y = 1 / 3 π 4x² h
multiply both sides by 3
πx²y = π 4x² h
divide both sides by π 4x²
Hence,
h = πx²y / π 4x²
h = y / 4
Therefore, the height of the cone is h = y / 4.

Some parallelograms are squares true or false
Answer:
True
Step-by-step explanation:
Parallelogram: A parallelogram is 4-sided shape that has parallel opposite sides
Square: A square is 4-sided shape where all sides are congruent and has 4 right angles. A square also has 2 pairs of opposite parallel sides.
Based on these definitions, we can see that not ALL parallelograms can be squares because a parallelogram can have no right angles, or can have all 4 angles be right angles.
All squares have to be parallelograms though because a square and a parallelogram both have 2 pairs of opposite parallel sides.
Hope this helps :)
For each problem, determine what will happen to the first factor?
10 x 1/2
15 x 7/2
When multiplying a whole number with a fraction, the first factor will be reduced to a fraction or a decimal, depending on the problem.
In both of the given problems, we are multiplying a whole number with a fraction. When we multiply a whole number with a fraction, we can simply multiply the whole number with the numerator of the fraction and keep the denominator as it is. So, in the first problem, we have 10 multiplied by 1/2. Multiplying 10 with 1 gives us 10, and then we divide it by 2, which gives us 5. Therefore, the first factor, which is 10, will be reduced to 5 in this problem.
In the second problem, we have 15 multiplied by 7/2. Multiplying 15 with 7 gives us 105, and then we divide it by 2, which gives us 52.5. Therefore, the first factor, which is 15, will be reduced to 52.5 in this problem.

Find the mean and the median of the data set.
Determine which of these values is greater.
A. The median, 4, is greater than the mean, 3.
B. The mean, 4, is greater than the median, 3.
C. The mean, 4, is greater than the median, 2.
D. The median, 5, is greater than the mean, 0.
The mean and the median of the data set is given as the median, 4, is greater than the mean, 3. The correct answer is option a.
To find the mean of the data set, we add up all of the numbers and divide by the total number of days. So, the mean is (1+4+5+5+1+5+5)/6 = 3.
To find the median, we first need to put the numbers in order from least to greatest: 1, 1, 4, 5, 5, 5. The median is the middle number, which in this case is 4.
Now we need to determine which value is greater. The options are:
A. The median, 4, is greater than the mean, 3.
B. The mean, 3, is greater than the median, 4.
C. The mean, 4, is greater than the median, 2.
D. The median, 5, is greater than the mean, 0.
We can eliminate options B and D because they don't make sense. The mean cannot be less than 0, and the median cannot be less than the mean.
Option A is correct. The median, 4, is greater than the mean, 3. This makes sense because there are two 1's in the data set, which bring down the mean. However, the median is not affected by outliers like this, so it remains higher.
Option C is incorrect because the mean is not 4, it is 3.
In summary, the mean of the data set is 3 and the median is 4. The median is greater than the mean, which is represented by option A.

The first steps in writing f(x) = 4x2 48x 10 in vertex form are shown. f(x) = 4(x2 12x) 10 (twelve-halves) squared = 36 what is the function written in vertex form? f(x) = 4(x 6)2 10 f(x) = 4(x 6)2 – 26 f(x) = 4(x 6)2 – 134 f(x) = 4(x 6)2 154
The function in vertex form is f(x) = 4(x - 6)² - 26.
How to write f(x) in vertex form?The function in vertex form is f(x) = 4(x - 6)² - 26.
To get to this form, the first step is to factor out the coefficient of x², which is 4:
f(x) = 4(x² - 12x) + 10
Next, complete the square by adding and subtracting (12/2)² = 36 inside the parenthesis:
f(x) = 4(x² - 12x + 36 - 36) + 10
Simplify the expression inside the parenthesis and combine like terms:
f(x) = 4((x - 6)² - 36) + 10
f(x) = 4(x - 6)² - 134
Therefore, the function in vertex form is f(x) = 4(x - 6)² - 26.
