Answer:

Step-by-step explanation:

There is no value on the y axis at points 0 and 12, so since that axis is meant to represent the car's speed, there is no movement at those two points. So D is the correct answer.

5 0

Answer:

Step-by-step explanation:

In this problem, the zeros of the graph are when the car is not in motion. The curve of the graph itself is the speed/when the car is in motion. You cannot have a negative mph or kph or negative movement, so your answer choice is D.

ozzi

Answer:

After 9 years the account will be worth 13709.60$

Step-by-step explanation:

We are given the following in the question:

We are given the following in the question:

P = $8000

r = 6% = 0.046

n = 12

The compound interest is given by:

$A = p\bigg(1+\dfrac{r}{n}\bigg)^{nt}$

where A is the amount, p is the principal, r is the interest rate, t is the time in years.

Putting the values, we get,

$13709.60 = 8000\bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\dfrac{13709.60}{8000} = \bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\Rightarrow 1.7137 = (1.005)^{12t}\\\Rightarrow t \approx 9$
