Therefore, the horizontal distance the golf ball travels before hitting the ground is approximately 254.55 meters.

In mathematics, an equation is a statement that shows the equality between two expressions, typically separated by an equal sign (=). An equation can contain one or more variables, which are symbols that represent unknown or varying values. The value of the variable(s) can be found by solving the equation.

Here,

The equation of the parabolic trajectory of the golf ball is given by:

f(x) = 0.84x - 0.0033x²

where x is the horizontal distance travelled by the ball and f(x) is the corresponding height at that distance. To find the highest point of the trajectory, we need to find the vertex of the parabola. The x-coordinate of the vertex is given by:

x = -b / 2a

where a and b are the coefficients of the quadratic term and the linear term in the equation of the parabola, respectively. In this case, we have:

a = -0.0033 and b = 0.84

Substituting these values into the formula, we get:

x = -0.84 / 2(-0.0033)

= 127.27

So the horizontal distance at the highest point of the trajectory is approximately 127.27 meters. To find the height of the highest point, we substitute this value of x into the equation of the parabola:

f(127.27) = 0.84(127.27) - 0.0033(127.27)²

f(127.27) ≈ 21.67

So the highest point of the trajectory is approximately 21.67 meters above the ground.

To find the horizontal distance the golf ball travels before hitting the ground, we need to find the two values of x where the height of the ball is zero (i.e., where the ball hits the ground). We can set f(x) = 0 and solve for x:

0 = 0.84x - 0.0033x²

0.0033x² = 0.84x

x = 0 or x = 254.55

So the golf ball hits the ground twice, once at x = 0 (i.e., where it was hit from the tee) and once at x ≈ 254.55 meters.

The values of missing variables are given by:

x = 51°, y = 105°, z = 90°.

We know that the sum of external and internal angles is 180°.

So from the given figure we can see that y° is the external angle and the corresponding internal angle is 75°.

So, 75° + y° = 180°

y° = 180° - 75° = 105°

And also external angle is right angle that is 90° and the corresponding internal angle is z°.

So, z° + 90° = 180°

z° = 180° - 90° = 90°

This is a pentagon and the sum of all internal angles = (5 - 2)180° = 3*180° = 540°

According to the given figure the sum of all internal angles of the pentagon is = (180° - 36°) + z° + (180° - x°) + (180° - 78°) + 75° = 144° + 90° + 180° - x + 102° + 75° = 591° - x.

So, 591° - x = 540°

x = 591° - 540° = 51°

Hence the value of missing variables are: x = 51°, y = 105°, z = 90°.

The number of bacteria present after 13 hours is 5,306.

The number of bacteria present after 13 hours is calculated by applying half-life equation.

In a function expressing altitute (h) in terms of time (t), finding the vertex will provide the time and altitute when the object reaches the maximum height. Therefore, let's use the vertex formula to see exactly when this happens:

"x" vertex value: [tex]-\dfrac{-b}{2a}[/tex]

a) For using that equation, first write the given equation on its standard form.

Standard form of quadratic equations: [tex]ax^{2} +bx+c=0[/tex]

b) You can substitute h(t) by 0 on the origina equation:

[tex]-0.2t^{2} +2t=0[/tex]

c) Idenfity the coefficients.

a= -0.2, beacuse "t²" is being multiplied by -0.2.

b= 2, beacuse "t" is being multiplied by 2.

d) Substitute in the formula and calculate.

[tex]\sf X\,value_{Vertex} =-\dfrac{-b}{2a}=-\dfrac{-(2)}{2(-0.2)}=-\dfrac{-(2)}{-0.4}=5[/tex]

So the "x" value of this h(t) equation is located on x= 5, therefore, the maximum point happens at x= 5. Since this is an equation that expresses altitute in terms of time, this means that 5 seconds after the object starts its movement it reaches its maximum altitute.

What is Algebraic expression ?

An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. It typically represents a mathematical relationship or formula and can be used to solve problems and make predictions.

Assuming you started with a value of 100, the value of the stock would be lower after these two weeks.

In the first week, the stock dropped by 60%, which means its value decreased to 40% of its original value. Therefore, the value of the stock at the end of the first week would be:

100 * 0.4 = 40

In the second week, the stock increased in value by 75%. Therefore, the value of the stock at the end of the second week would be:

Michio's answer not correct. He made a mistake when he was trying to convert the equation to logarithmic form. The right answer is  2.57

Looking at the equation 2(3)ˣ = 34, the best way to convert to logarithm is by isolating x.

we divide  2(3)ˣ = 34 by 2 on both side.

In logarithm form 3 becomes the base of the log

x = log₃(17)

x= 2.578

The answer above is based on the information seen in the picture.

The number for which the theoretical probability matches the experimental probability is 2.

Experimental probability and theoretical probability are two different ways to determine the likelihood of an event occurring.

Experimental probability is determined by performing an experiment or conducting observations and collecting data to see how often an event occurs. This method involves counting the number of times an event occurs and dividing that number by the total number of trials or observations.

Theoretical probability, on the other hand, is determined by using mathematical principles and calculations to determine the likelihood of an event occurring. It is based on the assumption that all outcomes are equally likely.

The surface area of the pyramid is approximately 74.24 square inches.

What is a pyramid?

A pyramid is a three-dimensional geometric shape that has a polygonal base and triangular faces that meet at a single point called the apex. The most common type of pyramid is a square pyramid, which has a square base and four triangular faces.

To find the surface area of the pyramid, we need to find the area of each of the four triangular faces and the area of the square base, and then add them up.

The area of each triangular face can be found using the formula:

Area = (1/2) * base * height

where the base is one of the sides of the square base and the height is the slant height of the pyramid.

The slant height of the pyramid can be found using the Pythagorean theorem:

slant height² = height² + (1/2 * base)²

where the height is the height of the pyramid, which is given as 7 inches, and the base is 4 inches.

height = 7 in.

base = 4 in.

slant height² = 7² + (1/2 * 4)² = 49 + 4 = 53

slant height = √53 ≈ 7.28 in.

Now we can find the area of each triangular face:

Area = (1/2) * base * height = (1/2) * 4 * 7.28 ≈ 14.56 in^2

There are four triangular faces, so the total area of the triangular faces is:

4 * 14.56 = 58.24 in²

The area of the square base is:

Area = side² = 4² = 16 in²

Finally, we can find the surface area of the pyramid by adding up the area of the triangular faces and the area of the square base:

Surface Area = 58.24 + 16 = 74.24 in²

Therefore, the surface area of the pyramid is approximately 74.24 square inches.

after 1000 years, approximately 259 mg of the original 500 mg sample of Radium-226 will remain.

what is approximately ?

Approximately means "about" or "roughly" and is used to indicate an estimated or approximate value or quantity, rather than an exact or precise one. For example, if someone says "the population of the city is approximately 1 million people," it means that the population is around 1 million,

In the given question,

The half-life of Radium-226 is 1590 years, which means that in 1590 years, half of the original sample will have decayed. After another 1590 years (or a total of 2 half-lives), half of the remaining sample will have decayed, leaving 25% of the original sample.

To find how much of the original sample remains after 1000 years, we need to first determine how many half-lives have passed.

Number of half-lives = elapsed time ÷ half-life = 1000 years ÷ 1590 years/half-life = 0.63

So, approximately 0.63 half-lives have passed. Therefore, the fraction of the original sample remaining is:

fraction remaining = (1/2)⁰°⁶³ ≈ 0.518

To find the remaining mass, we can multiply the fraction remaining by the initial mass:

remaining mass = fraction remaining x initial mass

remaining mass = 0.518 x 500 mg ≈ 259 mg

Therefore, after 1000 years, approximately 259 mg of the original 500 mg sample of Radium-226 will remain.
