Answer:
132.54cm²
Step-by-step explanation:
We can use the formula [ C²/4π ] to solve.
= 40.8²/4π
= 1,664.64/12.56
≈ 132.54cm²
Best of Luck!
Because it has a slope of 5, we can already set up part of the equation:
y = 5x
Now, we need to find the y-intercept.
We can do that by subtracting 1 from the x value of the provided coordinate pair, and subtracting 5 from 9.
1 - 1 = 0
9 - 5 = 4
The y-intercept is 4.
<h3><u>Our equation is y = 5x + 4</u></h3>
Slope = (y2 - y1) / (x2 - x1)
slope = (-7-10) / (5 - (-3)
slope is supposed to be -17/8
I am guessing she made her mistake by adding a negative sign...the student did : (-7 - (-10) / (5 - (-3) = (-7 + 10) / (5 + 3) = 3/8
x and 4x are supplementary to each other, meaning they add up to 180. So your equation is 180=5x. Divide both sides by 5 to get 36=x.
