Answer:I think it’s C
Step-by-step explanation:
The ladder is placed 6 feet away from the wall
The formula you have to use is a2 + b2= c2
(I used x instead of c)
225+36=x2
Add them
261=x2
Now find square root
Square root of x2=x
Square root of 261= 6.15549...
x=6.15549
The ladder can reach x feet
(f*g)(x)= (x+7)(1/x-13)
= (x+7)/(x-13)
so the domain ( -∞, 13)U(13,∞)
Answer:
a = 5√7
Step-by-step explanation:
Sides of a right triangle follow the Pythagoras theorem,
By Pythagoras theorem,
(AB)² = (BC)² + (AC)²
c² = a² + b²
If b = 9 and c = 16,
(16)² = a² + 9²
256 = a² + 81
a² = 256 - 81
a = √175
a = 5√7
Therefore, measure of third side a = 5√7
