Plotting the functions is highly recommended.
For A, the area under
over the interval [1, 2] is the area of rectangle with height 3 and width 2 - 1 = 1, so the area is

For B, the area under
plotted over the interval [0, 2] is the area of a triangle with height 1 and base length 2, so the area is

He is incorrect He wrote 50, when it should be 5.
Answer:
The slope of the line between these two points is 1.50.
Step-by-step explanation:
The general form of the regression line is:

Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>m</em> = slope
<em>c</em> = intercept.
The formula to compute slope using two-point method is:

In this case the dependent variable is the cost per week to feed and independent variable is the weight of the hamster.
The two points are:
(<em>x</em>₁, <em>y</em>₁) = (3, 3.50)
(<em>x</em>₂, <em>y</em>₂) = (4.8, 6.20)
Compute the slope as follows:




Thus, the slope of the line between these two points is 1.50.
Answer:
x + y = 400
5x + 9y = 2632
Step-by-step explanation:
I love these!
Okay, so this is a right angle. That means it is 90 degrees.
So far we know that on side of the angle is 47 degrees.
To get the other angle we will just subtract 90 - 47 = 43
