Amy makes a rectangular poster with an area of 21+28m square inches. The width of the poster is 7 inches as shown in the followi

Lesechka [4]

You could use simple factoring to solve this. You would factor out a 7 and then have

7(3+4m) = A

l x w = A

w= 3 +4m

K=mv^2/2 solve for v

matrenka [14]

Answer: $v=\sqrt[]{\frac{2K}{m} }$

Step-by-step explanation:

$K=\frac{mv^2}{2}$

First, multiply by 2 to get rid of the 2 in the denominator. Remember that if you make any changes you have to make sure the equation keeps balanced, so do it on both sides as following;

$2*K=\frac{mv^2}{2}*2$

$2K=mv^2$

Divide by m to isolate $v^2$ .

$\frac{2K}{m}=\frac{mv^2}{m}$

$\frac{2K}{m} =v^2$

To eliminate the square and isolate v, extract the square root.

$\sqrt[]{\frac{2K}{m} }=\sqrt[]{v^2}$

$\sqrt[]{\frac{2K}{m} }=v$

let's rewrite it in a way that v is in the left side.

$v=\sqrt[]{\frac{2K}{m} }$

What is the common ratio of the geometic sequence whose second and forth terms are 6 and 54, respectively?

Luda [366]

Answer:

Step-by-step explanation:

The n th term formula of a geometric sequence is

$a_{n}$ = a $r^{n-1}$

where a is the first term and r the common ratio

Using the second and fourth term, then

ar = 6 → (1)

ar³ = 54 → (2)

Divide (2) by (1)

$\frac{ar^3}{ar}$ = $\frac{54}{6}$ = 9

r² = 9 ⇒ r = $\sqrt{9}$ = 3 → C
