Answer:
-6.75
Step-by-step explanation:
V=127.16pi m^3
The formula for the Volume of a Cylinder is V=(pi)r^2h
First we have to fill in the variables with the information we have. The radius is 3.4m. The height is 11m. We want to leave the answer in terms of pi, so we won't multiply by pi at all. Let's plug it in.
V=(pi)3.4^2•11
To square a number we multiply it by itself, so 3.4 • 3.4 equals 11.56.
V=(pi)11.56•11
Next, we multiply the radius squared, which we already found by the height of the cylinder which is 11. 11.56 times 11 equals 127.16.
V=127.16pi
We found the final answer and don't use pi since we want it in terms of pi. Since a Cylinder is a 3-D figure, that means the units of measurement is cubed.
The answer is A) 127.16pi m^3
Answer:
B and D
Step-by-step explanation:
(2x-6):(6x-4)
you can divide everything by 2
2x÷2=x, -6÷2=-3
6x÷2=3x, -4÷2=-2
so it's B X-3:3x-2
(2x-6):(6x-4)
multiply everything by 2
2x × 2 = 2x, -6 × 2 = -12
6x × 2 = 12x, -4 × 2 = -8
so it's D (4x-12): (12x-8)
x^2-9x+18=0
So I'm gonna solve it as if you need to find the x values
So 18 is positive and 9 is negative, so we have to find 2 values that multiply to +18 but add to a -9
Which is negative 3 and negative 6. double - = +
(x-3) (x-6)
x intercepts ---> x= 3 x= 6
Answer:
Yes
Step-by-step explanation:
Slope intercept form is:
y=mx+b
where m is the slope, and b is the y intercept
We are given the slope, it is -3. We are also given the y intercept, (0,4). In this form, the 0 in (0,4) is ignored, and our y intercept is considered to be 4.
Therefore, m is -3, and b is 4.
y=mx+b
y=-3x+4
So, your answer is correct.
