Hey! So you’re gonna need to use the Pythagorean Theorem (a^2 + b^2 = c^2).
You’re looking for one of the legs here, so after inputting the values your equations should look like this: 6^2 + b^2 = 10^2.
Next, find what the numbers squared are: 36 + b^2 = 100.
Then, isolate the variable: b^2 = 64.
Lastly, square root both sides: √b^2 = √64.
You should find the answer is 8.
Answer:
x = [-b +-sq root (b^2 -4ac)] / 2a a=2 b=-2 c=3
x = [--2 +- sq root(4 - 4*2*3)] / 2*2
x = [2 +- sq root (-20)] / 4] / 4
x1 = 2 + 4.472135955 i / 4
x1 = .5 + 1.1180339887i
x2 = 2 - 4.472135955 i / 4
x2 = .5 - 1.1180339887i

Answer:
A) 1/30
Step-by-step explanation:
total of 25 coins at beginning
total of 24 coins after the first coin is drawn and spent
P('d' then 'n'): 5/25 · 4/24 = 1/5 · 1/6 = 1/30
Answer and Step-by-step explanation:
1. We can see that this kite-shape has 4 triangles in it.
The area of a triangle is as follows:
Where:
b = Base (length)
h = Height
<u>Top Right Triangle Area:</u>
b = 9
h = 3
A =
A =
<u>Bottom Right Triangle Area:</u>
b = 9
h = 3
A =
A =
<u>Top Left Triangle Area:</u>
b = 4
h = 3
A =
A = 6
<u>Bottom Left Triangle Area:</u>
b = 4
h = 3
A =
A = 6
Now, we add all the areas together to get the area of the kite figure.
A = +
A = 27 + 12
A = 39
<u>The area of the kite figure is 39 </u><u>.</u>
2. We have to find the area of the trapezoid.
(I'm not sure if the 9 is for the entire bottom side length)
- If the bottom side length is 9, then we would use the formula:
A =
to find the area of the entire trapezoid.
A = × 8.2
A ≈ 46.74
