Answer:

14 feet.

Step-by-step explanation:

Use the tangent function:

$tan\alpha = \frac{opposite}{adjacent}$

a = length of antenna:

$tan\70 = \frac{a}{15}$

$a = 15tan\70$

a = 14.09538931 ≈ 14

Answer:

x= 24, y= 33°

Step-by-step explanation:

MJ is part of the diameter of the circle and there is right angle between the diameter and HK

As the diameter and HK are perpendicular, HM=MK and mHJ= mJK

So,

x= 24

and

y= 66°/2= 33°

Identify the inverse variation and graph in which y = 0.75 when x = 4.

TiliK225 [7]

Answer:

$y=3/x$ or $yx=3$

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

in this problem we have

y=0.75 when x=4

Find the value of k

$y*x=k$

$k=0.75*4=3$

The equation is equal to

$y=3/x$

using a graphing tool

see the attached figure
