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

Please help i need the answer and how you got it!
Andreas93 [3]

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:

<h2>\huge a)\frac{1}{ {3}^{9}. {6}^{18}  }</h2>

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

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.
