ANSWER

b=1, c=81, and d=9.

EXPLANATION

The given function is:

y={x}^{2}-18x

This function is the same as:

y={(x - 9)}^{2}-81

To find the inverse of this function, we interchange x and y.

x={(y-9)}^{2}-81

Solve for y:

x+81={(y- 9)}^{2}

Take square root of both sides:

\pm \sqrt{x + 81}=y-9

y=\pm \sqrt{x + 81}+9

Hence,

b=1, c=81, and d=9.

Answer:  9.97

==============================================

Explanation:

y = distance from the base of the pole to the closest person

y+200 = total horizontal distance

-------------

Focus on the smaller right triangle.

tan(angle) = opposite/adjacent

tan(26) = 55/y

y*tan(26) = 55

y = 55/tan(26)

y = 112.76671 approximately

Make sure your calculator is in degree mode.

--------------

Now move to the larger right triangle

tan(angle) = opposite/adjacent

tan(x) = 55/(y+200)

tan(x) = 55/(112.76671+200)

tan(x) = 55/312.76671

tan(x) = 0.17585

x = arctan(0.17585) same as \tan^{-1}

x = 9.97349

x = 9.97 degrees approximately

PLEASE HELP ASAPPP !! Instructions: State what additional information is required in order to know that the triangles are congru
Svetllana [295]
<h3>Answer: angle T = angle W</h3>

Explanation:

We are given the sides are congruent due to the tickmarks. Specifically

TU = WV (single tickmarks)

TV = WX (double tickmarks)

So we just need the "A" of "SAS". The A is between the two S letters, so the angle is between the two sides. For triangle TUV, the angle T is between the two sides with the tickmarks. Similarly, angle W is between the tickmarked sides of triangle WVX.

If we know that angle T = angle W, then we have enough information to use SAS.
