Answer:
B)
Step-by-step explanation:
Given f(x) = ( 7 - 8x )²
let f(x) be y,
y = ( 7 - 8x )² .............to find inverse we have to make x the subject.
±√y = 7 - 8x
-8x = √y - 7
x = (±√y - 7 ) / -8
Then,
Inverse of ( 7 - 8x )² is and is a function.
The height of the canvas according to tangent is 14 inches.
According to the statement
we have given that the a rectangular canvas for his art project. its width must measure 20 inches and form a 35° angle with the diagonal of the canvas.
And we have to find the height of the canvas.
So, For this purpose,
The given information is:
The 35⁰ angle is part of a right triangle with a side of 20 inches. The tangent of this angle (35⁰) is equal to the opposite side, x, over the adjacent side (20 inches).
Tan (35⁰) = x/20
0.7002 = x/20
x = 14.004 inches.
For more understanding of the statement please see the image below.
So, The height of the canvas according to tangent is 14 inches.
