PLEASE, IT'S A 25 POINT QUESTION, BRAINLIEST IF YOU GET IT RIGHT, IF YOU DON'T INCLUDE EXPLANATION, YOU WILL GET REPORTED!!! A communications tower is located at the top of a steep hill, as shown. The angle of inclination of the hill is 65°. A guy wire is to be attached to the top of the tower and to the ground, 148 ft downhill from the base of the tower. The angle formed by the guy wire is 9°. Find the length of the cable required for the guy wire.

Step-by-step explanation:

pls ask

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
