PLEASE HELP WITH THESE TWO QUESTIONSSS 1. Which value is equivalent to sin20∘?
Nata [24]

Answer:

a) \cos(70\degree)

b) 12.72 units

Step-by-step explanation:

Recall that the sine and cosine are completed functions.

This means that:  \sin(x)=\cos(90-x)

\sin(20\degree)=\cos(90-20)

\sin(20\degree)=\cos(70\degree)

Recall that: sine ratio is opposite/hypotenuse

\sin 58=\frac{|PQ|}{15}

This implies that:

|PQ|=15\sin 58

|PQ|=15(0.848)

|PQ|=12.72

Four students found the mean of the data set 26, 31, 39, 30, 16, 16, 18, 38. which student found the correct mean? ashrita’s wor
balu736 [363]

In calculating the mean of this data set  Ashrita did the best job.

The  Mean of the data set is the most commonly used measures of central tendency.

It means the average value of the data set.

one doesn't have to arrange the data in order  for finding it.

<h3>What is the meaning of mean?</h3>

The data set value  takes is to add them all together and divide that by the number of the data.

It can be written as

,(x_1 + x_2 + x_3 + ..... + x_n) / n

Where x_1 , x_2 , x_3 , ..... ,x_nare the values in the data set

Therefore we can conclude that Ashrita did the best job in calculating the mean of this data set.

use the diagram to find the distance across the suspension bridge. Round your answer to the nearest foot
3241004551 [841]

Applying the tangent ratio, the distance across the suspension bridge is: 499.2 ft.

<h3>What is the Tangent Ratio?</h3>

Where we are given a right triangle, the tangent ratio is determined using the formula, tan ∅ = opposite side/adjacent side.

The diagram atatched beow whos the distance across the suspension bridge which consists of 6 identical right triangles.

Find the adjacent side of each right triangle using the tangent ratio:

∅ = 32

Opposite side = 52 ft

Adjacent side = x

Plug in the values into the tangent ratio:

tan 32 = 52/x

x = 52/tan 32

x = 83.2 ft.

Distance across the suspension bridge = 6(83.2) = 499.2 ft.

Therefore, applying the tangent ratio, the distance across the suspension bridge is: 499.2 ft.

A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(
gavmur [86]
We have the following function:
 f(t) = −16t2 + 34t + 546
 By definition, the average rate of change is:
 Avr = (f (t2) - f (t1)) / (t2 - t1)
 We have then:
 For t1 = 5:
 f (5) = -16*(5)^2 + 34*(5) + 546
 f (5) = 316
 For t2 = 5:
 f (7) = -16*(7)^2 + 34*(7) + 546
 f (7) = 0
 Substituting values:
 Avr = (0 - 316) / (7 - 5)
 Avr = -158
 Answer:
 The average rate of change of f (t) from t = 5 seconds to t = 7 seconds is -158 feet per second.
