Please solve for h: V=πr²h

1 answer:

8 0

Solve for h:V = π h r^2
V = h π r^2 is equivalent to h π r^2 = V:π h r^2 = V
Divide both sides by π r^2:
Answer: h = V/(π r^2)

How to find slope intercept form when slope equals 3 over 4 passing through 8, 2

IgorC [24]

Answer:

The slope intercept form would be y = 3/4x - 4

Step-by-step explanation:

To find the slope intercept form of this line, we start with using our given information in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y - 2 = 3/4(x - 8)

y - 2 = 3/4x - 6

y = 3/4x - 4

3/4 = c/36<br><br><br> I need help with this fraction proble.

Nataliya [291]

Answer:

c = 27

Step-by-step explanation:

given $\frac{3}{4}$ = $\frac{c}{36}$ ( cross- multiply )

4c = 3 × 36 = 108 ( divide both sides by 4 )

c = 27

note that $\frac{27}{36}$ = $\frac{3}{4}$ in simplest form

4.Is it sometimes, always, or never true that, if A and B both have dimensions n x n , AB=BA ? Explain.

REY [17]

Answer: Is true sometimes.

Step-by-step explanation:

I guess that here we have two matrices, A and B, that are nxn.

We can see that if those matrices can conmutate, then we can try it with some simple matrices.

$A = \left[\begin{array}{ccc}1&0\\0&-1\end{array}\right] . B = \left[\begin{array}{ccc}2&0\\1&1\end{array}\right]$

Here, we would have that:

$AB = \left[\begin{array}{ccc}2&0\\-1&-1\end{array}\right]$

$BA = \left[\begin{array}{ccc}2&0\\1&-1\end{array}\right]$

You can see that AB and BA are different, then the statement is not always true.

But it is true sometimes, if A or B are the identiti, then I*A = A*I, in this case would be true.

It is also true if A and B are diagonal matrices, let's prove it:

$A = \left[\begin{array}{ccc}a&0\\0&b\end{array}\right] , B = \left[\begin{array}{ccc}c&0\\0&d\end{array}\right]$

$AB = \left[\begin{array}{ccc}ac&0\\0&bd\end{array}\right] = BA$
