Answer

36 = 2 \times 2 \times 3 \times 3 \\   \:  \:  \:  \:  \:  \:  \:  \: =  {2}^{2}  \times  {3}^{2}

Step-by-step explanation:

First write the prime factors of 36 that you can see here

2 \:  \:  \: 2 \:  \:  \: 3 \:  \:  \: 3

Now write 36 as a product of its prime factors.

36 = 2 \times 2 \times 3 \times 3 \\   \:  \:  \:  \:  \:  \:  \:  \: =  {2}^{2}  \times  {3}^{2}

A mail order company charges 4.5% for shipping and handling. If the total order is 54.34 how much was the order total before shi
Andrews [41]

Answer:

$52

Step-by-step explanation:

Given that :

Amount charged for shipping and handling = 4.5%

Let cost of order = x

Total amount charged = 54.34

However,

total. Amount charged = (total cost + handling and shipping)

54.34 = x + 0.045x

54.34 = 1.045x

Order total before shipping = 54.34 / 1.045

Order total before shipping = 52

-3^2= -(3)^2

The exponent of 2 only applies to the number 3. -(3)^2 should equal -9. This is true because according to the order of operations, exponents should be evaluated before multiplication. The negative sign here represents -1* 3^2.
If you want to find -3 to the power of 2 it must be written (-3)^2.

What is the equation, in standard form, of a parabola that models the values in the table? x~ -1 0 2
Inessa05 [86]
<h2>Steps</h2>
  • Standard Form Equation: f(x) = ax² + bx + c

So firstly, since (0,5) is one of our values we can plug it into the standard form equation to solve for the c variable (since 0 will cancel out the a and b variable):

5=a*0^2+b*0+c\\5=c

Now we know that the value of c is 5. Next, plug in (-1,12) into the standard form equation and simplify (remember to also plug in 5 for the c variable):

12=a*(-1)^2+b*(-1)+5\\12=a-b+5\\7=a-b

Next, plug (2,15) into the standard form equation and simplify:

15=a*2^2+b*2+5\\15=4a+2b+5\\10=4a+2b\\5=2a+b

Now, with our last two simplified equations we will create a system of equations:

7=a-b\\5=2a+b

Now, I will be using the elimination method with this system. With the system, add up the equations together and you will get:

12=3a

From here, we can solve for the a variable. With it, just divide both sides by 3:

4=a

Now that we know the value of a, plug it into either equation to solve for the b variable:

7=4-b\\3=-b\\-3=b\\\\5=2(4)+b\\5=8+b\\-3=b

<h2>Answer</h2>

Putting all of our obtained values together, your final answer is:

f(x)=4x^2-3x+5
