Answer:
c. 
Step-by-step explanation:
I'd generally say this would depend on what your definition of proportional is, but there's still one clear answer in this case regardless.
Here, a direct proportional relationship will pass through (0, 0), meaning it will not have a y-intercept and y will be 0 when x is 0.

Because b is the y-intercept, C is the answer as it is the only answer that does not have one.
Answer:
A = 1011..59 ft^2
Step-by-step explanation:
The radius is 7 which means the diameter is 14. so we have a height of 16 and a length of 14 feet.
Answer:
The answer is 18x - 8.
Step-by-step explanation: Trust me, an know a lot about math.
The ball takes approximately a time of 2.041 seconds to reach its maximum height.
<h3>What time does the ball take to reach maximum height?</h3>
The height of the ball as a function of time is modelled by a <em>quadratic</em> equation, the required information can be found by transforming the expression into <em>vertex</em> form:
h = - 4.9 · t² + 20 · t + 12
h = - 4.9 · (t² - 4.082 · t - 2.449)
h + (- 4.9) · (6.615) = - 4.9 · (t² - 4.082 · t + 4.166)
h - 32.414 = - 4.9 · (t - 2.041)²
The ball takes approximately a time of 2.041 seconds to reach its maximum height.
