I need help finding the answers for this problem

Answer:

The answer to your question is:

a) 8.2 mi

b) 4.1 mi

c) 4.7 mi

Step-by-step explanation:

For 30°

         sin Ф = opposite leg / hypotenuse

         hypotenuse = opposite leg / sin 30

         hypotenuse = 4.1 / sin 30 = 4.1 / 0.5

         hypotenuse = 8.2 mi

For 90°

        d must be 4.1 mi because is over the observer at this angle

For 120°

       distance = opposite leg / sin 60

       distance = 4.1 / √3/2

                      = 4.71 mi

I hope it helps you!

Explain how to use a coordinate plane to find the area of a rectangle with vertices (–4, 9), (–4, –3), (–1, –3), and (–1, 9). wh
liberstina [14]

the formula for area of a rectangle is

Area = length x width

since both the length and the width of the rectangle lie on the same x and y axis, we can find the distance between the width and the distance between the length by subtracting

(-4,9) (-4,-3)

these points lie on the same x axis, so they create a vertical line

9-(-3) = 12

12 units is the distance between them

(-4,-3) (-1,-3)

these points lie on the same y axis, so they create a horizontal line

-1-(-4) = 3

3 units is the distance between them

now that we have the length and the width, we can find the area

A = 12 x 3

A = 36 units²

Which of the following point-slope form equations could be produced with the points (4, 5) and (-3, -5)?
NikAS [45]

Answer:

<em>Equation; y = 1 3 / 7x - 5 / 7</em>

Step-by-step explanation:

First consider the slope of this equation we must derive;

Slope Formula = Rise / Run,

y2 - y1 / x2 - x1 ⇒

5 - ( - 5 ) / 4 - ( - 3 ) ⇒

10 / 7 ⇒ Slope : 1 3 / 7

So far we can formulate an equation as such;

y = 1 3 / 7 * x + b, <em>where b ⇒ y - intercept</em>

Given one of the points, substitute into this equation solving for b;

5 = 1 3 / 7 * ( 4 ) + b,

5 = 40 / 7 + b,

b = - 5 / 7

From this we can derive one point - slope from equation to be :

<em>Equation; y = 1 3 / 7x - 5 / 7</em>

Using sigma notation write the geographic series: 6+12+24+48+96
Alika [10]

Answer:

$$\sum_{n=1}^{5} 6(2^{n-1}) $$

Step-by-step explanation:

6 + 12 + 24 + 48 + 96 =

= 6 + 6 * 2 + 6 * 4 + 6 * 8 + 6 * 16

= 6 + 6 * 2^2 + 6 * 2^2 + 6 * 2^3 + 6 * 2 * 4

= 6 * 2^(n - 1)

$$\sum_{n=1}^{5} 6(2^{n-1}) $$

I think it would be A, because if she jogged the same amount each day she jogged then all you need to do is multiply how much she jogged by how many days she jogged.
