Answer:
Last one
t = 1.5; it takes 1.5 seconds to reach the maximum height of 36 meters.
Step-by-step explanation:
h(t) = −16t² + 48t
h(t) = -16(t² - 3t)
h(t) = -16(t² - 2(t)(1.5) + 1.5² - 1.5²)
h(t) = -16(t - 1.5)² + 36
Axis of symmetry:
t = 1.5
Max height = 36

<u><em>The correct question is</em></u>
Graph the solution set to the system
Y<(1/5)x-0.41
we have
The solution is the shaded area below the dashed line 
The slope of the dashed line is positive 
The y-intercept of the dashed line is (0,-0.41)
The x-intercept of the dashed line is (2.05,0)
To find out the solution set, draw the intercepts and connect them to plot the dashed line, and shade the area below the dashed line

Answer:
14
Step-by-step explanation:
Since the volume of a prism is length*width*height, and the width is 3 and the height is 5 and the volume is 210, you get the equation 3x5x length=210. Solving it, you get length=14.
This is quite easy as it is simply knowing the formulas to solve different portions of the circle.
(A) To solve for circumference, the formula is d*pi where d is the diameter. The diameter is simply twice the radius, so we can just double 11 for it. This means 22 is the answer.
(B) The formula for area of a circle is pi*r^2, so for this one, we just need to square the radius. 11 squared is 121.
(C) To solve this, we should solve for the area of the circle, and then multiply it by 3 to represent the 3 dollars. To solve the area, we just substitute 11 into the formula for r. Afterwards, we should multiply it by 3 for the reason above. However, because we used 3.14 instead of pi, we must say the cost is approximately $1139.82. <span />
