Answer:
24
Step-by-step explanation:
The number of rows (x) should b equal to the number of columns (x).
x²=576
x=√576 taking the square root of the product
x=24
Answer:
y = 22.5 m
Step-by-step explanation:
given,
length of the tower = 90 m
distance between the towers = 1600 m
height of cable at 400 m = ?
we know
y = a x²
x is the distance from the center where the cable is touching the ground
at the far end y = 90 m and x = 800
90 = a × 800²
now height at x = 400
y = 22.5 m
height of the cables at 400 m is equal to y = 22.5 m
For inverse functions f(g(x)) = g(f(x)) = x
f(g(x)) = 4 - 3/2 (1/2 x + 3/2) = 4 - 3/4 x - 9/4 = 7/4 - 3/4x
Therefore, the functions are not inverses.
