Find the volume of a trapezoid with vertices at (2,0), (2,2), (4,0), and (4,4); about the x-axis.
mr Goodwill [35]
<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
 V =\int\limits^a_b { \pi y^2 } \, dx

∴ V =  \int\limits^4_2 { \pi y^2 } \, dx = \int\limits^4_2 { \pi x^2 } \, dx&#10;
∴V =  \pi  \ *  \frac{x^3}{3} &#10;
∴V =  \frac{ \pi }{3} * (4^3-2^3)=  \frac{56 \pi }{3}

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have bud
ddd [48]

Answer: See Below

Step-by-step explanation:

Create the equation:

$34 times the number of people plus the $50 cleaning fee has to be less than or equal to $3500

Or

34p + 50 <= 3500

34p <= 3450

p <= 101.470588....

We can have a part of a person attending the reception so we have to drop the remainder/decimal. Therefore the most amount of people that can attend the party and stay within budget is 101.
