The equation for percentage increase is
{(New value - old value) / old value} x100%
Therefore it should be
{(22.5 - 19.5) / 19.5} x 100%
=15% (rounded to nearest whole number)
Answer is B
Answer: 230 - 180
Step-by-step explanation:
Answer:
D. Y = 200(1.18)^x
Step-by-step explanation:
The answer represents the correct exponential growth function. (1.18)^x represents the rate of change and 200 represents the starting value

Answer:
means the inverse function
=
Step-by-step explanation:
means the inverse function
to find an inverse function, flip the x and y variables and solve for y
f(x) = 5x^3 - 6
y = 5x^3 - 6
x = 5y^3 - 6
x + 6 = 5y^3
(x + 6)/5 = y^3
= y
