Answer:

$53\frac{1}{2}\ in$

Step-by-step explanation:

we know that

The perimeter of a square is equal to

$P=4a$

where

a is the length side of the square

in this problem we have

$a=11\frac{3}{8}\ in$

convert to an improper fraction

$11\frac{3}{8}\ in=\frac{11*8+3}{8}=\frac{91}{8}\ in$

Find the perimeter of the square

$P=4\frac{91}{8}=45.5\ in$

Remember to adds two extra inches for each corner

The wood needed is

$45.5\ in+2*4\ in= 53.5\ in$

convert to mixed number

$53.5\ in=53\frac{1}{2}\ in$

Solve the following logarithmic equations.<br> 5 log(x + 4) = 10

Ede4ka [16]

Answer:

$x=e^{2} -4$

Step-by-step explanation:

Divide both sides by 5:

$log(x+4)=\frac{10}{5} \\log(x+4)=2$

Cancel logarithms by taking exp of both sides:

$e^{log(x+4)}=e^{2} \\x+4=e^{2}$

Solve for x subtracting 4 from both sides:

$x=e^{2} -4$

I need help!!! please help me out as quick as possible

Alenkasestr [34]

Answer:

D) 262,144

Step-by-step explanation:

The given sequence is given explicitly as:

$A_n = {4}^{n - 1}$

We want to find the tenth term of this sequence.

We substitute n=10 to get:

$A_ {10}= {4}^{10 - 1}$

Simplify the exponent

$A_ {10}= {4}^{9}$

Simplify the power

$A_ {10}= 262144$

Therefore the 10th term is 262,144

What is the formula for t in this equation : s=1/2at^2 .

9966 [12]

<span>s=1/2at^2
2s = at^2
t^2 = 2s/a
t = + square root (2s/a) and </span>t = - square root (2s/a)
or
+ square root (2sa)
t = ------------------------------
a
and
- square root (2sa)
t = ------------------------------
a
