Answer:
253cm²
Step-by-step explanation:
Area of the trapezoid = 1/2(b1+b2)*h
Given
h = 22cm
b1 = 10.5cm
b2 = 12.5cm
Substitute
Area of the trapezoid = 1/2(10.5+12.5)*22
Area of the trapezoid = 1/2(23)*22
Area of the trapezoid =11*23
Area of the trapezoid = 253cm²
Hence the area of the trapezoid is 253cm²

The circumference of a cylinder is 20 inches and the volume is 600 cubic inches. Calculate the height.
Answers
Answer:
h = 18.88 inches
Step-by-step explanation:
Given that,
The circumference of a cylinder is 20 inches
The volume of the cylinder, V = 600 cubic inches
We need to find the height of the cylinder. We know that the volume of a cylinder is given by :
[tex]V=\pi r^2h[/tex]
r is radius
We know that,
circumference = 2πr
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{20}{2\pi}\\\\r=3.18\ \text{inches}[/tex]
So,
[tex]h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{600}{\pi\times (3.18)^2}\\\\h=18.88\ \text{inches}[/tex]
So, the height of the cylinder is 18.88 inches.

[tex]7[/tex]
Step-by-step explanation:
This means that there are 20 terms in between 11 and 31
[tex]31-11=20[/tex]
Since we know that the [tex]11th[/tex] term is [tex]29[/tex] and the [tex]31st[/tex] term is [tex]169[/tex], you can subtract the two to find out the values in between
[tex]169-29=140[/tex]
Now all we have to do is divide the values in between by the number of terms to find the common difference.
[tex]\frac{140}{20} =7[/tex]
Therefore the common difference is [tex]7[/tex]

Which term makes the equation y=sup(x,3)+2x+1 nonlinear?
Answers
Answer:
sup(x,3)
Step-by-step explanation:
Linear equation:
A linear equation has the following format:
[tex]y = ax + b[/tex]
In a linear equation, when x changes by 1, y will always change by the amount a, which is called slope.
In this question:
y=sup(x,3)+2x+1
[tex]y = 2x + 1[/tex] would be a linear equation.
However, the expression sup(x,3), that is, the higher value between x and 3, means that the function is not linear.
