Step-by-step explanation:
When we multiplying, we find the sum of the exponents so
[tex]3 {}^{ \frac{1}{2} } \times 3 {}^{ \frac{1}{2} } \\ {3}^{ \frac{1}{2} + \frac{1}{2} } \\ = {3}^{ \frac{2}{2} } \\ = 3[/tex]

There is a sale on Blu-rays in a local shop – 20% off selected items. Your favorite Blu-ray before the sale cost $18. How much will you save? How much will you pay?
Answers
Answer:
save $3.6, pay $14.4
Step-by-step explanation:
A cd costs $18
If there is a 20% discount, you only have to pay 80% of the original price.
This means you only have to pay (0.80 x $18=) $14.4 dollars, which means you saved ($18 - $14.4=) $3.6.
Or you could just do $18 x 0.20 = $3.6

Show set of data that is a function using at least 5 domain values and 5 range values. It can be shown in a format of your choice
Answers
Answer:
Five domain values of the function f(x) = x² - 1, are; 1, 2, 3, 4, 5
Five range values of the function f(x) = x² - 1, are; 0, 3, 8, 15, 24
Step-by-step explanation:
The values in the domain are the values of the independent or (normally) x-variable
The values i the range are the values obtained by applying the function relationship to the domain as follows;
Let 'f(x)' represent the function that generates the values of the data in the data set,
For f(x) = x² - 1, we have the following table;
[tex]\begin{array}{ccc}x&f(x)\\1&0\\2&3\\3&8\\4&15\\5&24\end{array}[/tex]
Therefore;
The function is f(x) = x² - 1
The five domain values are; 1, 2, 3, 4, 5
The five range values are; 0, 3, 8, 15, 24.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Variables
Stuffed bears = b
Stuffed dogs = d
Step 2: Define Systems
$7b + $8d = $3800
b + d = 500
Step 3: Rewrite Systems
b + d = 500
[Equality Property] Multiply everything by -7: -7b - 7d = -3500Step 4: Redefine Systems
7b + 8d = 3800
-7b - 7d = -3500
Step 5: Solve for d
Elimination
Combine 2 equations: d = 300Step 6: Define Answer
d = 300 means that the students bought 300 stuffed dogs.
Answer:
D
Step-by-step explanation:
Remark
Let the stuffed bear = x
Let the stuffed dog = y
Equations
x + y = 500 (1)
7x + 8y = 3800 (2)
Solution
There are two ways you could do this. You can use substitution or you could use multiplying equation 1 by either 7 or 8 to get rid of the x or y.
Multiply (1) by 7
7x + 7y = 3500 (3) Write equation (2) below (3) and subtract
7x + 8y = 3800 Subtract
-y = - 300 Multiply by - 1
y = 300
Use the result for y to get x using equation 1
x + y = 500
x + 300 = 500 Subtract 300
x = 500 - 300
x = 200
Stuffed bears = 200
Stuffed dogs = 300

How many degrees are on
the interior of a Polygon that
has 18 sides?
Answers
Answer:
ask yourself
Step-by-step explanation:
Answer:
160.00° Degrees
Step-by-step explanation:
To find the answer, we have to use the interior angle formula which is
(n-2)*180, where n is the number of sides. This formula gives us the sum of all interior angles in a polygon having ‘n’ sides.
For a polygon with 18 equal sides, first finding the sum of all interior angles of the polygon:-
=(n-2)*180= (18–2)*180=16*180=2880 degree.
We found the sum of all interior angles of 18 sided polygon and it is 2880 degrees.
The polygon we are considering has all sides equal, which means it is a regular polygon. So we can conclude that all of its interior angles are equal.
Sum of all eighteen angles=2880, One angle=2880/18=160 degrees.
Thus, we concluded that the interior angle of the regular eighteen sided polygon
is 160 degrees
Sami lights up a candle every 10 minutes. Every candle burns for exactly 40 minutes. How many candles are burning exactly 55 minutes after Sami lit up the first candle?
Answers
Answer:
4
Step-by-step explanation:
Candle is lit every 10 minutes :
Number of candles lit in 55 minutes:
Starting from 0 minute ; Numbe rod candles lit on 55 minutes = 6
1st candle burns out after 40 minutes
Second burns out after 50 minutes
Third will burn out after 60 minutes
Hence Number of candles still burning :
Number of candles lit - Number of candle burnt out
6 - 2 = 4 candles

Check whether -2 is a zero of the polynomial 3x2 + 4x + 32 .
Answers
Answer:
x = - 2 is not a zero
Step-by-step explanation:
If x = - 2 is a zero of the polynomial then f(- 2) = 0
f(x) = 3x² +4x + 32
f(- 2) = 3(- 2)² + 4(- 2) + 32 = 3(4) - 8 + 32 = 12 - 8 + 32 = 36
Since f(- 2) ≠ 0 , then x = - 2 is not a zero of the polynomial

Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario? Each water bottle is same price and each bag of chips is same price. * A) 3w + 2c = 9.45 AND 5w + 4c = 14.75 B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 3) 2w + 3c = 14.75 AND 4w + 5c = 9.45 D) 5c + 9w = $24.20
Answers
Answer:
B) 2w + 3c = 9.45 AND 4w + 5c = 14.75
Step-by-step explanation:
Let us represent:
Number of water bottles = w
Number of bag of chips = c
Hence:
Samaia buys two water bottles and three bags of chips for $9.45.
2w + 3c = 9.45......Equation 1
Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75.
4w + 5c = 14.75......Equation 2
Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario?
Option B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 is the correct option.
