ANSWER

EXPLANATION
We want to find the number of years that it will take the population to double.
To do this, we have to apply the exponential growth function:

where y = final value
a = initial value
r = rate of growth
t = time (in years)
For the population to double, it means that the final value must be 2 times the initial value:

Substitute the given values into the function above:

To solve further, convert the function from an exponential function to a logarithmic function as follows:

Solve for t:

It will take 9 years for the population to double.
Answer: A compound event is the combination of two or more simple events (with two or more outcomes).
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Z is the only relation that does not pass the vertical line test, so Z is not a function.
Answer: D
Area of a triangle is A = (1/2) (b) (h). Here we are given A and b and need to find h.
A = 24 ft^2 = (1/2) (4 ft) (height)
24 = 2(height) => height is 12 ft (answer)
Answer:
False
Step-by-step explanation:
a - (-b) would make it a + b
negative and negative equals positive
