A person standing 130 feet away from the foot of a tall building must look up at an

angle of 30° to see the top of the building.

There is a radio antenna on the top of the

building. The angle of elevation of the top of

the radio antenna is 45°.

Write an equation to determine the

height of the radio antenna.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
