Answer:

The equation that models the situation is A(t) = 13(1.0078)^t

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

A(t) = A(0)(1+r)^t

In which A(0) is the starting value and r is the growth rate, as a decimal.

Starting value of 13 and a growth rate of 0.78%.

This means that A(0) = 13, r = 0.0078

Write an equation to model the situation.

A(t) = A(0)(1+r)^t

A(t) = 13(1+0.0078)^t

A(t) = 13(1.0078)^t

The equation that models the situation is A(t) = 13(1.0078)^t

Help quick! I'll mark your answer as the brainliest if your answer is correct!
Anna007 [38]

Answer:

They would never intersect because they are parallel lines. You can tell they are parallel lines because they have the same slope and they have a different y-intercept. However, this doesn't mean that there was no solutions, there were, thats how i was able to tell what their slopes and y-intercepts were. So if there is an answer that you can choose from that explains that they won't intersect because they are parallel then that is the correct answer. It may be C, but I would see if there is another option.

Vikki [24]
First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
                      (1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.
