Answer: 5.2cm^3

Steps:
Volume of a cylinder- V = π * r^2 * h
146.952 = π * 3^2 * h
146.925 = π * 9 *h
146.925 = 28.2743338823 * h
146.925 / 28.2743338823 = h

5.19640889201 = h
5.2 = h

Given the replacement set {0,1,2,3,4}, solve 6x-9=15

stepan [7]

You can solve this two ways:
One is by substituting in the numbers until you get 15=15.

6(0)-9=15
0-9=15
-9=15

6(1)-9=15
6-9=15
-3=15

6(2)-9=15
12-9=15
3=15

6(3)-9=15
18-9=15
9=15

6(4)-9=15
24-9=15
15=15
Solution is x=4

or you can find the value of x
by first adding 9 to both sides to get x by itself

6x-9=15
6x=24

Then divide by 6
x=4

Carter divided the polynomial 6x2 + 4x + 3 by the monomial 2x using long division, and got an answer of 3x + 2 + . His work is s

Gnesinka [82]

Answer:

C. Both Carter and Demi are correct and would get the same answer.

Step-by-step explanation:

Here, the given polynomial is : $P(x) =6x^2 + 4x + 3$

The given monomial : $Q(x) = 2 x$

Now, according to the given question:

Dividend = P(x), Divisor = Q(x)

Now, Carter divide P(x) by Q (x) with LONG DIVISION METHOD.

If we divide P(x) by Q(x) by Long division, we get:

$\frac{P(x)}{Q(x)} = \frac{(6x^2 + 4x + 3)}{(2x)} = 3x + 2 + \frac{3}{2} x = R(x)$

Also, if Demi divides each term of P(x) by The given monomial (2x) , we get:

$\frac{P(x)}{Q(x)} = \frac{(6x^2 + 4x + 3)}{(2x)} = \frac{6x^2}{2x} + \frac{4x}{2x} +\frac{3}{2x} \\= 3x + 2 + \frac{3}{2} = R(x)$

⇒In both the case, R(X)Quotient is SAME.

Hence, Both Carter and Demi are correct and would get the same answer.
