Follow PEMDAS!

First E (exponent) so you'd do 2^2=4

Then S (subtract) so you'd do 3-4=-1

your answer is -1

Answer:

No, the pool will not fit.

Step-by-step explanation:

Radius of pool: 3.14 r^2= 379.94

Divide by 3.14: r^2= 121

Square root both sides: r=11

11>10, thus the pool won't fit.

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

law of exponent
PEMDAS

<h3>tips and formulas:</h3>

${x}^{ - y} < = > \frac{1}{ {x}^{y} }$
$( {x} ^{z} )^{y} < = > {x}^{y \times z}$

<h3>let's solve:</h3>

$( {3}^{3} . {6}^{6} {)}^{ - 3}$

$\frac{1}{( {3}^{3}. {6}^{6} {)}^{3} }$

$\frac{1}{ {3}^{3 \times 3}. {6}^{6 \times 3} }$

Given the system of equations:

mr_godi [17]

Answer:

Step-by-step explanation:

Given the system of equations:

2x + 3y = 15

X + 3y = 0

What is x?

2x + 3y = 15

X + 3y = 0 subtract the bottom equation fron the top one

2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero

2x - x = 15

x = 15 Now for extra credit what is y?

X + 3y = 0

15 + 3y = 0

15 - 15 + 3y = 0 - 15

3y = -15

3y/3 = -15/3

y = -5

-15

-5

Step-by-step explanation:

diameter i.e. d = 12ft

radius i.e r= 6ft

Area of the circle is given by,

$\pi {r}^{2} = 3.14 \times {(6)}^{2}$

$= 3.14 \times 36 = 113.04 \: \: {ft}^{2}$

Write the geometric sequence in function notation.

Anni [7]

Answer:

a(n) = 7*2^(n - 1)

Step-by-step explanation:

The first term of the given geometric sequence, 7, 14, 28, 56, 112, ... , is 7, and the common ratio is 2. Each new term is twice the previous term.

Thus the general formula for the geometric sequence becomes

a(n) = 7*2^(n - 1).

As a check, let's see whether this formula correctly predicts the fourth term (56): Here n = 4, and so a(4) = 7*2^(4 - 1) = 7*2^3 = 7*8 = 56. Yes.
