Answer:
Option D.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
f(t) = a*sin (b*t +c) + d
Please, see attached picture below.
By looking at the picture with all the possible cases, we can tell that the correct option is D.
The function has a period of T = 6π
Max . Amplitude = 9
Min . Amplitude = -5
Answer:
2
Step-by-step explanation:
4.0 has 2 significant digits.
The zeros after a non zero number are significant.
Any non zero number is significant.
0.004 has 1 significant digit.
4000 has 4 significant digits.
In your case 4.0 × 10^3 there is an exception because it is in scientific notation. So there are 2 significant digits.
hope this makes sense.

<h2>
Horizontal distance when projectile strikes water surface is 170 .02 feet</h2>
Step-by-step explanation:
The height is given by

We need to find when it strikes the water surface,
At water surface h = 0 feet
Substituting

Solving this quadratic equation to get x.
-32x² + 2500x + 500000 = 0
32x² - 2500x - 500000 = 0
x = 170 .02 feet or x = -91.90 feet
Negative x is not possible
Horizontal distance when projectile strikes water surface = 170 .02 feet
Answer: x<8
