Answer:
Area = 24.75 sqr units
Step-by-step explanation:
You will need these formulas:
![d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_2%20-%20x_1%29%5E2%20%2B%20%28y_2-y_1%29%5E2%7D)
Midpoint = ![(\frac{x_{1} + y_{1} }{2} , \frac{x_{2} + y_{2} }{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx_%7B1%7D%20%2B%20y_%7B1%7D%20%7D%7B2%7D%20%2C%20%5Cfrac%7Bx_%7B2%7D%20%2B%20y_%7B2%7D%20%7D%7B2%7D%29)
Area = b x h
Let us treat CD as the base. Find the length of the base with the distance formula. Use the coordinates for points C & D.
![d = \sqrt{(-2 - (-8))^2 + (-8-(-7))^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-2%20-%20%28-8%29%29%5E2%20%2B%20%28-8-%28-7%29%29%5E2%7D)
![d = \sqrt{37}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B37%7D)
The base is
.
The height is the distance between point E and the midpoint of line CD.
Midpoint of CD =
= (
,
)
Use the distance formula to find the height.
![d = \sqrt{(-5 - (-\frac{15}{2} ))^2 + (-2-(-5))^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-5%20-%20%28-%5Cfrac%7B15%7D%7B2%7D%20%29%29%5E2%20%2B%20%28-2-%28-5%29%29%5E2%7D)
![d = \frac{\sqrt{61} }{2}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B%5Csqrt%7B61%7D%20%7D%7B2%7D)
Find the area with the two distances that were found.
Area = ![(\sqrt{37}) (\frac{\sqrt{61} }{2})](https://tex.z-dn.net/?f=%28%5Csqrt%7B37%7D%29%20%28%5Cfrac%7B%5Csqrt%7B61%7D%20%7D%7B2%7D%29)
Area = ![\frac{\sqrt{2257} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B2257%7D%20%7D%7B2%7D)
Area = 24.75 sqr units
<em>Answer:</em>
<em>x = 2√5</em>
<em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>x² = 20</em>
<em>x² = 4×5</em>
<em>x² = 2²×5</em>
<em>x = √2²×5</em>
<em>x = 2√5</em>
<em>Good luck !</em>
Answer:
300 times bigger.
Step-by-step explanation:
That would be (1.8 * 10^27 ) / (6 * 10^24)
= 0.3 * (10^27/10^24)
= 0.3 * 10^3
= 3 * 10^2
= 300.
Answer:
<u>$21.56</u>
Step-by-step explanation:
- Original price = $3.85
- Marked up by 40% = 3.85 x 1.4 = $5.39 per bottle
<u>Cost and discount of 5 bottles</u>
- Cost = 5 x 5.39 = $26.95
- Discount of 20% = 26.95 x 0.8 = <u>$21.56</u>
Answer:
1 ofc
Step-by-step explanation:
Think of it:
1% is pretty much ![\frac{1}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B100%7D)
so the equal to that is 1
