Answer:
<h3> f^−1(x) = x + 7</h3>
Step-by-step explanation:
Replace f(x) with y. y = x − 7
Interchange the variables. x = y − 7
Solve for y. y = x + 7
Solve for y and replace with f^−1 (x). f^−1(x) = x + 7
I hope this helps have a great day :)
Answer:
AE = 21.471cm long
(Rounded to 3 sig figs would be 21.5cm)
Step-by-step explanation:
Use the pythagorean theorem to find the length of AH
10^2 + AH^2 = 25^2
AH^2= (625 - 100)
AH = Square root of (525)
AH = 22.913
Plug in this value for AH to solve for AE using the pythagorean theorem
HE^2 + AE^2 = AH^2
8^2 + AE^2 = 22.913^2
AE^2 = 525 - 64
AE = Square root of (461)
AE = 21.4709
Hope this helps!
