Write each expression using a single exponent x^9/x^2
Answer:
[tex]x^{7}[/tex]
Step-by-step explanation:
using the rule of exponents
[tex]\frac{a^{m} }{^{a^{n} } }[/tex] = [tex]a^{(m-n)}[/tex] , then
[tex]\frac{x^{9} }{x^2}[/tex] = [tex]x^{(9-2)}[/tex] = [tex]x^{7}[/tex]
The expression (x⁹)/(x²) in single exponent is x⁷.
To write the expression (x⁹)/(x²) using a single exponent
we can apply the exponent rule for division, which states that when dividing two exponential expressions with the same base, we subtract the exponents:
[tex]\frac{a^m}{a^n}=a^m^-^n[/tex]
(x⁹)/(x²)
= x⁹⁻²
= x⁷
Therefore, the expression (x⁹)/(x²) can be simplified to x⁷.

Work out
m
and
c
for the line:
y
=
x
+
4
Answer:
m = 1
c = 4
Step-by-step explanation:
First let's review what a slope-intercept form is.
Slope-intercept form is a specific form of linear equations. It always has y on one side and all the other terms on the other. Its structure is:
[tex]y = mx + c[/tex],
where m is the slope and c is the y-intercept.
You can easily read slope (m) and intercept (c) in your equation.
[tex]y = mx + c\\y = x + 4[/tex]
You can see that m in front of x is 1, because x = 1x. Multiplying with 1 perserves the number.
So:
[tex]m = 1\\c = 4[/tex]
You have been given data about gas prices in 15 states.
2018 Gas Price Data
Max: $2.42
Min: $2.03
Mean: $2.098
Median: $2.06
Mode: $2.04
Variance: 0.0121
Standard Deviation: $0.1098
What does the mean and median of the data say about gas prices in 2018?
Both the mean and the median can be used to describe where the “center” of a dataset is located. It’s best to use the mean when the distribution of the data values is symmetrical and there are no clear outliers. It’s best to use the median when the distribution of data values is skewed or when there are clear outliers.
Find a function y of x such that 2yy′=x and y(2)=6
Answer:
[tex]y=\sqrt{\frac{x^{2}}{2} +34}[/tex]
Step-by-step explanation:
[tex]2y\left( x\right) y^{\prime }\left( x\right) =x[/tex]
[tex]\Longrightarrow \int 2y\left( x\right) y^{\prime }\left( x\right) dx=\int x\ dx[/tex]
[tex]\Longrightarrow y^{2}\left( x\right) =\frac{x^{2}}{2} +c\ \text{(c is a constant)}[/tex]
[tex]y\left( 2\right) =6\Longleftrightarrow y^{2}\left( 2\right) =36[/tex]
[tex]y^{2}\left( 2\right) =36\Longleftrightarrow \frac{\left( 2\right)^{2} }{2} +c=36\ \Longleftrightarrow c=34[/tex]
[tex]\Longrightarrow y\left( x\right) =\pm\sqrt{\frac{x^{2}}{2} +34}[/tex]
Which equation can be used to find A, the area of the parallelogram shown?
Explanation:
The area of a parallelogram is equal to base times height.
The base and height are always perpendicular to one another. Usually the base is horizontal along the ground (if not then you'd need to rotate your paper until it is, but that step is optional).
The base is 6 meters and the height is 7 meters.
Therefore, area = base x height = 6 x 7
The side of 11 meters is not used at all. It's likely put in there as a distraction.
Answer:
A = 6 * 7
Step-by-step explanation:
A parallelogram follows the same rules as a regular quadrilateral, as the only difference is that both its sides have been moved along.

Amelia's car used 16 gallons to travel 656 miles. How many gallons of gas would she need to travel 533 miles?
Answer:
13 gallons of gas.
Step-by-step explanation:
If amelia used 16 gallons of gas for 656 miles, she is traveling 41 miles per gallon. (656 divided by 16). So we take the amount she needs to travel which is 533, and divide it by 41 because 41 miles is equal to one pound of gas, so, 533 divided by 41 is 13, she needs 13 gallons of gas to travel 533 miles.

Rewrite each fraction with a denominator of 24. 2/3 and 5/8
Answer:
2/3 of 24 is 16/24
5/8 of 24 is 15/24
Step-by-step explanation:
if you multiply across 2/3 by 8/8 it equal to 16/24
if you multiply across 5/8 by 3/3 it equal to 15/24
Answer:
16/24 and 15/24
Step-by-step explanation:
To get the denominator in 2/3 to be 24 we multiply by 8 since 3 * 8 = 24, since we multiplied the denominator by 8 we must multiply the numerator by 8 as well to keep things equal, therefore 2 * 8 = 16, and we arrive at 16/24.
Likewise for 5/8, to get the denominator 8 to be 24, we multiply by 3, multiplying the numerator by 3 to keep things equal will result in 15/24.

The histogram is shown below.7/10 of the class passed the assignment.============================================================
Explanation:
Part 1
Sort the data values to get
51, 54, 58, 60, 60, 62, 70, 72, 72, 75, 76, 80, 85, 88, 90, 90, 95, 100, 100, 100
Now let's say we had these intervals
51-6061-7071-8081-9091-100Notice each interval is 9 units wide.
The 5 scores 51,54,58,60,60 are in the interval 51-60, which means the first interval has a bar that's 5 units tall.
The scores 62,70 are in the interval 61-70, which means the second bar is 2 units high.
Keep this process going to create the histogram shown below.
It looks like you have the right idea, but your class interval widths aren't the same each time.
Because the class interval widths can change, this means other histograms are possible. Just be sure to stick to one interval width.
-----------------------------------
Part 2
Set A = set of scores that are 70 or larger, i.e. those who passed
Set A = {70, 72, 72, 75, 76, 80, 85, 88, 90, 90, 95, 100, 100, 100}
Set B = set of all scores in the class
Set B = {51, 54, 58, 60, 60, 62, 70, 72, 72, 75, 76, 80, 85, 88, 90, 90, 95, 100, 100, 100}
There are 14 items in set A and 20 in set B

Step-by-step explanation:
When writing decimals into fractions, you first take the last digit, (in this case 9), and place it as your numerator, then count how many decimal places there are after 0. <---- in our case we have 3 decimal places which means our denominator has 3 zeros. Hence it is 1000.

Answer:
[tex]m\angle{W} = {75{^\circ}}[/tex]
[tex]m\angle{Y} = {15{^\circ}}[/tex]
[tex]m\angle{Z} = {90{^\circ}}[/tex]
Step-by-step explanation:
All angles in a triangle must add up to [tex]180{^\circ}[/tex]
First we can use an equation to find [tex]x[/tex]
[tex](x - 15) + (2x - 165) + 90 = 180[/tex]
[tex]3x - 180 = 90[/tex]
[tex]3x = 270[/tex]
[tex]x = 90[/tex]
Now we can solve for [tex]\angle W[/tex]and [tex]\angle Y[/tex] through substitution
[tex]\angle{W} = 90 - 15 \rightarrow \boxed{75{^\circ}}[/tex]
[tex]\angle{Y} = 2x - 165 \rightarrow 2(90) - 165 \rightarrow 180 - 165 \rightarrow \boxed{15{^\circ}}[/tex]
Now we can classify the triangle
It is right because it has a [tex]90{^\circ}[/tex] angle
