A skateboarding ramp is 13in. high and rises at an angle of 13°. How long is the base of the ramp? Round to the nearest inch.

Answers

Answer 1
Answer:  Approximately 56 inches

===========================================================

Explanation:

The diagram is shown below. We know the vertical part of the triangle is 13 inches, which is the side opposite the reference angle 13 degrees. The adjacent side is unknown. We'll call it x. This is how long the base of the ramp is, which is the horizontal distance along the entire ramp. This distance is on the ground. The ramp itself is the hypotenuse but it seems like your teacher isn't wanting to know this value. So we'll ignore the hypotenuse.

We'll use the tangent rule to connect the opposite and adjacent sides.

tan(angle) = opposite/adjacent

tan(13) = 13/x

x*tan(13) = 13

x = 13/tan(13)

x = 56.309186365694

x = 56 inches is the approximate horizontal distance underneath the ramp

A Skateboarding Ramp Is 13in. High And Rises At An Angle Of 13. How Long Is The Base Of The Ramp? Round
Answer 2

The base of the ramp is 57 inches long.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The tangent function relates the opposite side (height) and adjacent side (base) of a right triangle to the angle of elevation.

We know the opposite side is the height of the ramp, which is 13 inches, and the angle of elevation is 13 degrees.

Let the adjacent side (the base of the ramp) be "x".

The tangent of 13 degrees is equal to the opposite side divided by the adjacent side:

tan(13) = 13/x

To solve for x, we can multiply both sides by x:

x × tan(13) = 13

Then, we can divide both sides by tan(13):

x = 13 / tan(13)

x = 13 / 0.228

x= 56.99

Therefore, the base of the ramp is 57 inches long.

The function f(x) = x² +9 and the other function P is given by P(x) = f(x) - 34 ÷x + 5 find P (5 )​

Answers

Answer:

32.2

Step-by-step explanation:

Given :

f(x) = x² +9

P(x) = f(x) - 34 ÷ x + 5

P(5) =?

Substitute 5 for X on P(x)

P(5) = f(5) - 34 ÷ x + 5

f(5) = 5² + 9 = 25 + 9 = 34

P(5) = 34 - 34 ÷ 5 + 5

According to PEMDAS

-34 ÷ 5 = - 6.8

P(5) = 34 - 6.8 + 5

P(5) = 34 - 1.8

P(5) = 32.2

if lian got 93.16, we add 113.25 to 93.16 to get rei's amount.

113.25 + 93.16 = 206.41

The value here is 10 -1 +50 -10 +100 +100 +100 = 349.

Additional comment

Letters are assigned to 1 and 5 and those values multiplied by 10 or 100. When you get to 4000 and above, special forms apply. By convention, only unit values within a factor of 10 are subtracted. In the above number, 49 is written XLIX, not IL.

The one-to-one functions g and h are defined as follows

Answers

Answer:

[tex]g^-^1(x)=-8[/tex]

[tex]h^-^1(x)=\frac{x-4}{3}[/tex]

[tex](h^-^1 \ o\ h)(-3)=-3[/tex]

Step-by-step explanation:

When given the following functions,

[tex]g=[(-2,-7),(4,6),(6,-8),(7,4)][/tex]

[tex]h(x)=3x+4[/tex]

One is asked to find the following,

1. Question 1

[tex]g^-^1(4)[/tex]

When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;

[tex]g^-^1(4)[/tex]

[tex]g(4)=6\\g(6)=-8\\g^-^1(4)=-8[/tex]

2. Question 2

[tex]h^-^1(x)[/tex]

Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,

[tex]h(x)=3x+4\\\\h(x)-4=3x\\\\\frac{h(x)-4}{3}=x\\\\\frac{x-4}{3}=h^-^1(x)[/tex]

[tex]h^-^1(x)=\frac{x-4}{3}[/tex]

3. Question 3

[tex](h^-^1 \ o\ h)(-3)[/tex]

This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function ([tex]h^-^1[/tex]) and simplify. Then substitute (-3) into the result.

[tex]h^-^1\ o\ h[/tex]

[tex]\frac{(3x+4)-4}{3}\\\\=\frac{3x+4-4}{3}\\\\=\frac{3x}{3}\\\\=x[/tex]

Now substitute (-3) in place of (x),

Answers

Answer:

a. μ = 25

b. σ = 16.496

Step-by-step explanation:

Note: See the attached excel for the calculation of Mean and Deviation from Mean.

Let: N = Number of observation = 9

F = Frequency

Therefore, we have:

a. Compute the expected number of arrivals per minute. μ=___( please type as an integer or a decimal)

From the attached excel file, we have:

Total F = 200

Therefore, we have:

μ = Mean = Total of F / (N - 1) = 200 / (9 - 1) = 25

b. Compute the standard deviation σ=___(please round to three decimal places as needed)

From the attached excel file, we have:

Total (F -  μ)^2 = 2,177

σ = Standard deviation = (Total of (F -  μ)^2 / (N - 1))^0.5 = (2,177 / (9 - 1))^0.5 = 16.496

Step-by-step explanation:

Jada should choose the tank that has a higher probability of choosing a ball with even number from.

Tank of tennis balls has two even numbers out of the ten balls (2, 4)

Tank of golf balls has seven even numbers out of the ten balls.

Tank of golf balls would give Jada more chance to pick an even number to win the game

Therefore, Jada should use the tank of golf balls
