Answer:
1/1
Step-by-step explanation:
graph the equation and than put it in a fraction of rise over run.
Answer:
3.6 m
Step-by-step explanation:
The garden has a rectangular shape; the area of a rectangle is given by
where
A is the area
L is the length
W is the width
For the garden in this problem, we have:
is the area
is the length of the garden
Therefore, we can re-arrange the equation in order to find W, the width of the garden:
Answer:
2035.6 is the slope of the regression line and represents the increase in payscale for every additional year of experience.
Step-by-step explanation:
The relationship between the payscale and years of experience in the company is represented by the equation:
This is a linear regression model of the form
where m is the slope of the regression line and c represents the intercept.
So in the original equation, 2035.6 corresponds to the slope of the regression line and represents the increase in payscale for every additional year of experience.
Answer:
See answers below.
Step-by-step explanation:
<u>Large Rectangle:</u><u> </u> length x width = (x + 3)(x - 4) =
x² - 4x + 3x - 12
x² - x - 12
<u>Smaller Rectangle:</u> length x width = (x)(3) = 3x
<u>Shaded Region: </u>shaded area = lg. rectangle minus small rectangle
A = (x² - x - 12) - 3x
A = x² - 4x - 12
<u>Solve for x, if shaded reion's area is 48 square units: </u>
48 = x² - 4x - 12
x² - 4x - 12 -48 = 0
x² - 4x - 60 = 0
(x - 10)(x + 6) = 0
x - 10 = 0 or x + 6 = 0
x = 10 or x = -6
But x represents a length, so x cannot be -6.
x = 10
First, you must find the width of GHJK. Since the area of it is 84m², divide 84 by 7.
84÷7=12
So the width of GHJK is 12m.
Next, find the scale of GHJK to LMNP. Since the height of both are already available, you can divide 21÷7 to get 3
This means that to get the width of LMNP you must multiply the width of GHJK by 3.
12×3=36.
Now, to get the area of LMNP, multiply 21 by 36.
21×36=756
So, the area of LMNP is 756m². (Don't forget the units!>
