Xy = -10/ 4
= -2.5
So, xy = -2.5
Answer:
A
Step-by-step explanation:
The constant rate of change in this question simply means the slope
To get the slope, we simply get two points and apply the slope equation;
The points are;
(3,60) and (6,30)
The slope equation is;
m = (y2-y1)/(x2-x1) = (30-60)/(6-3) = -30/3 = -10 ft/s
So our answer is the first option as it represents a decent of -10 ft/s
<span>The trapezoid have vertices at (2,0), (2,2), (4,0), and (4,4)
and the rotation </span><span>about the x-axis.
the points (2,0), (4,0) are located on the x-axis
calculate the function y = m x + c using the other </span>vertices <span>(2,2), (4,4)
by substituting in the function y
m = 1 , and c =0
∴ y = x
</span>The volume can be calculated using

∴

∴

∴
2(x+6)=14
steps:
1. 2x+12=14, distribute the 2.
2. 2x=2, subtract 12
3. x=1, divide 2
