Answer:
F. 82
Step-by-step explanation:
To calculate the length of BC, Pythagoras theorem will be used.
It says, Hypotenuse^2 = Perpendicular^2 + Base^2
In our case, Perpendicular = AB = 18 and Base = AC = 80
therefore,
Hypotenuse^2 = 18^2 + 80^2 = 6724
Hypotenuse = BC =
= 82
Answer:
B. 1/12.
Step-by-step explanation:
There are 3 even numbers on the die so Probability(an even) = 3/6 = 1/2.
Probability (rolling a 4) = 1/6.
Probability ( rolling an even then a 4) = 1/2 * 1/6 = 1/12.
let point A has coordinates (-9;12),B(-3;12),C(-5;10) and D(-11;10).Then the vector AB={6;0}, BC={2;-2}, CD={6;0}, AD={2;-2} and their and the length of the vectors
![|AB| = |CD| = \sqrt{ {6}^{2} + {0}^{2} } = \sqrt{36} = 6 \\ |BC| = |AD| = \sqrt{ {2}^{2} + {( - 2)}^{2} } = \sqrt{8}](https://tex.z-dn.net/?f=%20%7CAB%7C%20%3D%20%7CCD%7C%20%3D%20%5Csqrt%7B%20%7B6%7D%5E%7B2%7D%20%2B%20%7B0%7D%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B36%7D%20%3D%206%20%5C%5C%20%7CBC%7C%20%3D%20%7CAD%7C%20%3D%20%5Csqrt%7B%20%7B2%7D%5E%7B2%7D%20%2B%20%7B%28%20-%202%29%7D%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B8%7D%20)

Answer: The first box
Step-by-step explanation:
V represents volume and r represents radius
So V(r) represents the volume of the basketball with respect to radius
Answer:
Step-by-step explanation:
If you want the mid point for these questions then for the 1st
1. add -6 and -2 which is -8 then divide by 2 which is -4, then add -1 and -3 which is -4 and then divide by 2 which is -2. so the mid point is (-4,-2)
2. its the same as above first add -4 and 2 which is -2 then divide by 2 which is -1, then add -5 and 3 which is -2 and divide by 2 which is -1. the point is (-1,-1)
3. -3+3=0 dived by 2 which is 0, -1+5=4 divide by 2 which is 2
point is (0,2)
4. -3+4=1 divide by 2 which is 1/2 =0.5, -2+7=5 then divide by 2 which is 5/2=2.5. point is (0.5,2.5)
