The shadow of a vertical tower is 79.0ft long when the angle of elevation of the sun is 30.0 degrees. Find the height of the tower.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
