Answer:

C. $81

Step-by-step explanation:

To find out how much money would be in Terence's account balance after 2 weeks, we can use the formula provided to us.

A(t)=100(0.9)^t

Next, we plug in 2 in the formula:

1) A(t)=100(0.9)^2     First, solve the squared portion.

2) A(t)=100(0.81)    Next, multiply the last 2 numbers.

A(t)=81

Terence's account balance after 2 weeks will be C. $81

For the function f(x) = x2 ­ -12, find (f o f­-1)(4) A. 0 B. 4 C. 10 D. 6
slega [8]

We actually don't need to do any computation. By definition, the inverse function f^{-1} changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.

You have to think like this: if the function makes a step further, the inverse function makes that same step back.

This means that the composition f \circ f^{-1} is always the identity function f(x) = x. In fact,

(f\circ f^{-1})(x) = f(f^{-1}(x)) = x

So, for every function, you have

(f\circ f^{-1})(4) = f(f^{-1}(4)) = 4

The graph of a system of equations is
Dovator [93]

Answer:

The system has no solution.

Step-by-step explanation:

In order for the system to have a solution, both graphs must have an intercept to each others. We see in the picture that both graphs are parallel and do not have any interceptions which we don't know the solution to the system.

That means if graphs are parallel and have no interceptions, there are no solutions. The system of equations are for finding the interceptions of both graphs. But of course! Parallel lines do not intercept.

If you have any questions, feel free to ask.
