Answer:
Step-by-step explanation:
Formula for volume of a circle: V=πr²
If you multiply the circle by height, it becomes a cylinder.
Formula for volume of a cylinder: V=πr²h
Plug in the numbers and get r by itself:
471 = πr²(6)
Divide both sides by 6:
78.5 = πr²
Divide both sides by π:
25 = r²
Square root both sides:
= 
²
5 = r
Radius is 5 cm
The domain is a discrete set. So we will have a discrete range.
The range is a set containing:
f(-2)=-11
f(-1)=-9
f(0) = -7
f(1) = -5
f(2) = -3
Range = {-11,-9,-7,-5,-3}
Answer:
3x+5y=4
Step-by-step explanation:
y=-3x/5 + 4
move the 5 to the other side so:
5y=-3x+4
then move -3x to the other side so:
5y+3x=4
and that is yr answer
Answer:
The answer is B
Step-by-step explanation:
A) is a negative answer
C) Is a rational answer
D) is a whole number
We first standardise
:
P(1224 >
)=P(
>
)
which reduces to finding P(Z > 1.2) = 0.115
