Answer: 1: B
Step-by-step explanation:
X = -2 and -5
You can set both equal to 0 to find the answers.
Answer:
I = 91.125
Step-by-step explanation:
Given that:
where E is bounded by the cylinder and the planes x = 0 , y = 9x and z = 0 in the first octant.
The initial activity to carry out is to determine the limits of the region
since curve z = 0 and
∴
Thus, z lies between 0 to
GIven curve x = 0 and y = 9x
As such,x lies between 0 to
Given curve x = 0 , and z = 0,
y = 0 and
∴ y lies between 0 and 9
Then
I = 91.125
The figure is a trapezoid (or trapezium), and the exact length of the trapezoid is 5 units
<h3>How to determine the length?</h3>
The figure is a trapezoid with the following parameters:
Area = 107.95
Base= 12
Height = 12.7
Length = x
The area of a trapezoid is:
Area = 0.5 * (Base + Length) * Height
So, we have:
0.5 * (12 + Length) * 12.7 = 107.95
Evaluate the product
(12 + Length) * 6.35 = 107.95
Divide both sides by 6.35
12 + Length = 17
Subtract 12 from both sides
Length = 5
Hence, the length of the trapezoid is 5 units
