Answer:
2,144.7
Step-by-step explanation:
The formula for the volume of a sphere is V=4pi r^3/3. Lets apply this formula for your sphere. The radius is 8, so lets plug in 8 in our formula. 4pi 8^3/3. Now, lets solve. 4 times pi. What is pi? We usually think of pi as 3.14. 4x3.14 is 12.56. Now, lets do 8^3/3. 8 times 3 is 512, and divided by 3 is 170.67. Alright, now we have 12.56 times 170.67. That is 2144.7 rounded to the nearest tenth.
Answer:
1. R
2. Match the year with the price. For example, 2006 should have a line directly on 15.
3. A (The first number on each row is the second number multiplied by 4)
4. C
5. A
MAKE SURE TO DOUBLE-CHECK JUST IN CASE!
Answer:
-9
Step-by-step explanation:
You have to plug 8 into the formula for x. f(8) = -2(8)+7 = -16+7 = -9
Answer:
x-int:(-2,0)(-4,0) . y-int:(0,8)
Step-by-step explanation:
y = x2+6x+8 and y = (x+2)(x+4)
x-int:
x+2=0
x= -2
(-2,0)
x-int:
x+4=0
x=-4
(-4,0)
y-int: plug 0 for x
y=(0+2)(0+4)
y=8
(0,8)
Answer:
19683
Step-by-step explanation:
As the formula of the geometric sequence:
![a_{n} =a_{1} *r^{n-1}](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3Da_%7B1%7D%20%2Ar%5E%7Bn-1%7D)
In the sequence of 1, 3, 9..., you have a1 = 1 and r = 3. Therefore:
![a_{10} =1 *3^{10-1} = 3^{9} =19683](https://tex.z-dn.net/?f=a_%7B10%7D%20%3D1%20%2A3%5E%7B10-1%7D%20%20%3D%203%5E%7B9%7D%20%3D19683)
Hope this helps!
