Answer:
The inverse is ±sqrt((x+4)/9)
Step-by-step explanation:
y = 9x^2 – 4
We want to find the inverse
Exchange x and y
x = 9y^2 -4
Solve for y
Add 4 to each side
x+4 = 9y^2 -4+4
x+4 = 9y^2
Divide each side by 9
(x+4)/9 = 9/9y^2
(x+4)/9 = y^2
Take the square root of each side
±sqrt((x+4)/9) = sqrt(y^2)
±sqrt((x+4)/9) = y
The inverse is ±sqrt((x+4)/9)
Answer:
e) 75
Step-by-step explanation:
Given the following :
Total length of cable = 60 foot
Length of each stripe = (4/5) of a feet
Number of stripes = ( total cable length / length of each stripe)
Number of stripes = ( 60 / (4/5))
Number of stripes = 60 ÷ 4/5
Number of stripes = (60 * (5/4)
= (60 * 5) / 4
= 300 / 4
= 75
Number of stripes made = 75
