Your math teacher asks you to calculate the height of the goal post on the football field. You and a partner gather the measurements shown. Find the height of the goal post, rounded to the nearest tenth of a foot.

Answers

Answer: The height of the goalpost is 41.6 feet (to the nearest tenth of a foot)

Step-by-step explanation: The figure shows an observer looking up at a goalpost at an angle of elevation of 61 degrees. The observer is 20 feet away from the base of the goalpost and he is standing 5.5 feet from the ground. This means the total height of the goalpost shall be an addition of the observer's height plus the calculated length of the portion of the goalpost as indicated by the right angled triangle.

We now have a right angled triangle, with one of the other two angles measuring 61 degrees and this shall be the reference angle. The side facing the reference angle is the opposite and is yet unknown. Also, the length from his position to the base of the goalpost is the adjacent (the side that lies between the right angle and one of the other two sides. To calculate the height,

Tan 61 = opposite/adjacent

Tan 61 = opposite/20

Tan 61 x 20 = opposite

1.8041 x 20 = opposite

36.082 = opposite.

Remember that the entire length of the goalpost includes the height of the observer (which is 5.5 ft). The height of the goalpost therefore is

Height = 5.5 + 36.082

Height = 41.582

The height of the goalpost rounded to the nearest tenth of a foot is

41.6 feet

The height of the goal post rounded to the nearest tenth is 41.6 ft

The situation forms a right angle triangle .

Properties of a right angled triangle:One of its angle is equals to 90 degreesThe sides and angle can be found using trigonometric ratios.

The height of the goal post is the height of the person plus the height of the triangle formed.

Therefore, lets find the height of the triangle formed using trigonometric ratios,

tan 61° = opposite / adjacent

tan 61° = h / 20

cross multiply

h = 20 tan 61

h = 20 × 1.80404775527

h = 36.0809551054

Therefore,

height of the goal post = 36.0809551054 + 5.5 = 41.5809551054

height of the goal post ≈ 41.6 ft

Step-by-step explanation:

The answers are all in slope-intercept form: y= mx+b. In slope-intercept form m represents the slope and b represents the y-intercept. (Its confusing, I know).

The slope here is 2/1 or 2. Considering rise/run we can see that the line goes up (rise) two (2) points and over (run) one (1).

Now we have y= 2x+b, we just need the y-intercept.

Looking at the y-axis, the line crosses at (0, -3). So the y-intercept is -3!

That gives us y=2x-3

Harrison plays a game in which he uses a net to catch balls that are randomly launched from holes in the ground. The height of one ball after t seconds is represented by the function f(t) = –16t2 + 20t. After how many seconds does the ball return to the ground? Round to the hundredths place as needed. seconds

Answers

Answer:

The ball will return to the ground after 1.25 seconds

Step-by-step explanation:

Given

f(t) = -16t² + 20t

Required

After what time (in seconds) does the ball return to the ground?

Function f(t) is a function of time and it represents the displacement of the ball.

For the ball to return to the ground, it means the displacement is 0.

So, we have f(t) = 0.

Substitute 0 for f(t) in the above, we have

0 = -16t² + 20t ---- Factorize

0 = -4t(4t - 5) ---- Reorder

-4t(4t - 5) = 0

This above expression can be splitted to;

-4t = 0 or 4t - 5 = 0

For -4t = 0,

divide through by -4

This will give t = 0

For 4t - 5 = 0,

Collect like terms

4t = 5 + 0

4t = 5

Divide through by 4

t = 5/4

t = 1.25

So, we have that

t = 0 or t = 1.25

But t can't be 0 because the ball has already traveled some distance.

So, t = 1.25

Hence, the ball will return to the ground after 1.25 seconds

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the trigonometric relation be represented as A

Now , the value of A is

A = cot ( sin⁻¹ ( -1 ) )    be equation (1)

On simplifying , we get

The value of ( sin⁻¹ ( -1 ) ) = -π/2

where sin (-θ) = -sin (θ)

So , A = cot ( -π/2 )

From the trigonometric relations ,

cot (-θ) = -cot (θ)

cot ( -π/2 ) = 0

Hence , the trigonometric relation is solved

Federal agencies are specialized government institutions created for a particular function, such as resource management, financial regulation of specific sectors, or matters of national security. Although a presidential order may also be used to establish these organisations at first, legislative action is usually required to establish them.

The Securities and Exchange Commission (SEC) was founded as an independent federal agency by the Securities Exchange Act of 1934. The Securities and Exchange Commission (SEC) is one of the most wide and powerful bodies, enforcing Securities legislation in the United States controlling the bulk of the securities business. In addition to other electronic securities markets and enterprises, it oversees stock exchanges, options markets, and options exchanges in the United States.

Answers

7/18 is the answer because you have 7 blue marbles and 18 marbles in total. So when you write it as a fraction, it would be 7/18.

The probability of choosing a blue marble is 7/18.

To find the probability of choosing a blue marble, we use the formula:

Probability = Number of favorable outcomes / Total number of possible outcomes

In this case, the number of favorable outcomes is 7 (because there are 7 blue marbles) and the total number of possible outcomes is 18 (because there are 7 blue marbles + 5 green marbles + 5 red marbles + 1 yellow marble). So the probability of choosing a blue marble is 7/18.
