Answers
Answer:
B, D, D, B, C
Step-by-step explanation:
1) The part of the equation that tells us the graph would open downward would be B, the negative coefficient of [tex]x^{2}[/tex].
We know this because, if we reorganize the equation into the standard form y = mx + b, we get y = -(x²) + 1. This means that for any value we substitute for x, y will always be negative. The answer is B.
2) To find the zeroes of this function, we just have to see which answer makes the function, well, zero.
We have the equation y = (-16t - 2) (t - 1)
We set the equation equal to zero like this:
0 = (-16t - 2) (t - 1)
We also know that anything multiplied by zero will equal zero, so:
0 = (-16t - 2) and 0 = (t - 1)
Now we just solve for t in both equations:
0 = -16t - 2
-16t = 2
t = 2/-16 or -1/8
0 = t - 1
t = 1
So our answer will be D.
3) This time, we are given the same equation but the variable t represents time and y represents the height.
The zeroes are when y = 0, so the zeroes (which are 1 and -1/8 from the last problem) mean that the height is also at zero (which is the ground).
Furthermore, time cannot be negative, so the correct answer choice would be D.
4) We are given the same equation and story problem, but instead we are asked to find the height when the ball was thrown. In other words, we need to find the y-intercept.
The y-intercept is when t = 0, so:
y = (-16t - 2) (t - 1)
y = (-16(0) - 2) (0 - 1)
y = (-2) (-1)
y = 2
So, the correct answer is B, 2 feet.
5) This problem is a simple theoretical question. We know that the constant c will represent the vertical translation or y-intercept, so the correct answer is C.

IN PARALLELOGRAM BCHS IF BC = 15, BS = 12, and SH = (3x - 3), WHAT IS THE VALUE OF THE VARIABLE x?
Answers
Answer:
6
Step-by-step explanation:
Given a parallelogram BCHS
Opposite side of the parallelogram are equal hence;
BC = HS
Given
BC = 15, BS = 12, and SH = (3x - 3),
15 = 3x-3
3x = 15+3
3x = 18
x = 18/3
x = 6
Hence the value of x is 6

If the diameter of a circle is increased by 6 cm, what is the increase in the circumference of the circle?
Answers
Answer:
The circumference will be larger by 3 cm.
Step-by-step explanation:
We know that the circumference of a circle is C = 2πr, where r is the radius. The circumference can also be expressed as C = 2π [tex]\frac{d}{2}[/tex], where d is the diameter (since the radius is half the diameter).
So, if we increase the diameter by 6:
C = 2π [tex]\frac{(d+6)}{2}[/tex]
C = 2π [tex]\frac{d}{2}+\frac{6}{2}[/tex]
C = 2π [tex]\frac{d}{2}[/tex] + 3
If we compare this to the original equation, C = 2π [tex]\frac{d}{2}[/tex], we see that if we increase the diameter by 6 cm, the circumference will be larger by 3 cm.

He makes 525 simple interest in those 5 years so you add that to the initial amount, to find his total after 5 years.

if the arithmetic mean of 5 and c is 11,what is the value of c?
Answers
Answer:
c = 17
Step-by-step explanation:
(c + 5) : 2 = 11
c + 5 = 22
c = 17
If the arithmetic mean of 5 and c is 11, the value of c is 17.
What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called average of the values of the considered data set.
It serves as predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.
If the arithmetic mean of 5 and c is 11, then the value of c.
(c + 5) : 2 = 11
c + 5 = 22
c = 17
Hence, the value of c is 17.

Step-by-step explanation:
Since the formula to find the area of a pallelogram is A=base × height
I divided the area by either the Base or the height (depending which one the problem had gave me)
Therefore 147 will be divided by 15 3/4.
Then 140 5/8 will be divided by 11 1/4.
Finally 151 3/16 would be divided by 10 1/4.

The temperature at 12 am was 44 degrees. The temperature dropped steadily for the next 8 hours to reach the daytime low of 20 degrees. Create an equation for the relationship between temperature and the time.
Answers
Answer:
y=-3x+80
Step-by-step explanation:
Points (12,44) and (20,20)
slope = -3
Equation of line: y - 44 = -3(x - 12)
The equation for the relationship between temperature and time is
T = 44 - 3x
Where x is the number of hours and T is the temperature.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at 12 am = 44°
The temperature after 8 hours = 20°
Now,
The temperature drops steadily.
This means,
Temperature drops in an hour.
= (44 - 20) / 8
= 24/8
= 3°
The equation for the temperature after x hours.
= 44 - 3x
Thus,
The steady temperature drop in an hour is 3°.
