Answer:
0.18 sec or 3.4 sec.
For second part, it will take 3.7 sec.
First part:
Set h(t) = 17and solve for t.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.

Answer:
12%
Step-by-step explanation:
You are going to want to use a modified compound interest formula, as shown below. This version of the compound interest formula is what you use to solve for the interest rate.
![r=n[(\frac{A}{P})^{1/nt}-1]](https://tex.z-dn.net/?f=r%3Dn%5B%28%5Cfrac%7BA%7D%7BP%7D%29%5E%7B1%2Fnt%7D-1%5D)
r = interest rate (decimal)
n = numbers of times compounded (annually)
A = total amount
P = principal amount
<em>t = time (years)</em>
Now, lets plug in the values:
![r=1[(\frac{6,000}{3,000})^{1/(1)(6)}-1]](https://tex.z-dn.net/?f=r%3D1%5B%28%5Cfrac%7B6%2C000%7D%7B3%2C000%7D%29%5E%7B1%2F%281%29%286%29%7D-1%5D)
Next, multiply <em>r </em>by 100 to get our answer:
The last step is to round our answer to the nearest whole number:
12.246 -> 12
There is exactly one x-intercept. Then the correct option is A.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function.
The continuous function that generated the following table of values will be
x -3 0 1 5 11
y 4 -3 2 0 7
The value of y at x-intercept will be 0.
Then there is exactly one x-intercept.
Then the correct option is A.
