V = pi * r^2 * h
.22 = 3.14 * r^2 * .84
.22 = 2.6 r^2
divide both sides by 2.6
.08 = r^2
r = .3 the radius is approximately .3 m

CHECK
V = 3.14 * .3^2 * .84
V = .24 m^3

Answer:

\huge\boxed{\texttt{Yes. Explanation for why.}}

Step-by-step explanation:

If we have the equation y = \frac{1}{2}x - 4 and we want to test if the point (4,–2) satisfies the equation, we can plug the x and y values into the equation and see if they make the equation true.

4 is the x value, -2 is the y.

-2 = (\frac{1}{2}\cdot4)-4

-2 = 2 - 4

-2 = -2

So this does satisfy the equation.

Hope this helped!

Let f(x) = –4x and g(x) = 5x2. Andrew finds the composition [f o g](x) as shown below. What error did Andrew make? = 5(–4x)2 = 5
Elden [556K]
F(g(x)) means you take the g function and put it into x in the f function.  He took the function and put it into the g, which was the incorrect order.  He should have had this: f(g(x))=-4(5x^2)

26=4v+3v+12 can anyone help?
motikmotik

Answer:

Step-by-step explanation:

Combine like terms

3v + 4v

26=7v+12

Subtract    12  from both sides of the equation

26-12

12-12

14=7v

Simplify

so subtract the 12's

Divide both sides of the equation by the same term

14 divided by 7

7 divided by 7

Simplify

do the division and move the term on the other side and it would be

v=2

Solution

 

v=2
