Is (–2n)^4 = –8n^4? Choose the best explanation for why or why not.
A. Yes; –2 times 4 makes –8, and the n becomes n^4.
B. Yes; for n = 1, (-2n)^4 = -8 x 1 not equal to -8n^4
C. No; for values other than 0, (–2n)^4 = 16n^4 not equal to –8n^4.
D. No; the negative in front of the 2 means –2n^4 needs to become 1/2n^4

Answer:

y = -2x+4

y = (3/2)x -3

The point of intersection is (2, 0), or x=2 and y=0.

Step-by-step explanation:

The downward-sloping line drops 2 grid squares for each 1 it goes to the right, so its slope is -2. It intersects the y-axis at +4. In slope-intercept form, its equation is ...

y = slope · x + (y-intercept)

y = -2x + 4

Similarly, the upward-sloping line rises 3 grid squares for each 2 it goes to the right, so its slope is 3/2. It intersects the y-axis at -3. Its equation is ...

y = (3/2)x -3

The two lines intersect at the point where x=2 and y=0, so the coordinates are (2, 0). These are the values of x and y that satisfy both equations, so are the solution to the system.

Answer:

18.6 units

Step-by-step explanation:

A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. A diagonal can be drawn between opposite corners that splits the triangle into two equal right triangles. The distance of this diagonal is found using the Pythagorean Theorem a² + b² = c². In the rectangle a = 11 and b = 15. Substitute these values and simplify using a square root operation.

11² + 15² = c²

121 + 225 = c²

346 = c²

√346 = c

18.6= c

Step-by-step explanation:

median only shows the amount in the very middle. to represent how much money he makes in daily tips, he needs to find the mean (the average).

Answer:

Little close

Step-by-step explanation:

In statistics, when we have a list of entries to be analyzed we have few figures for observation. These are

Mean , median and mode.

Mean gives the average of all the entries. By average means.

Median gives you the middle most entry.

And mode gives the entry repeated the most.

As by definition we see that , median will give us approximation regarding daily data, hence jacob must consider the median to best represent the money he makes on daily basis.

Answer:

Alecia lives farther from school

Step-by-step explanation:

Georgia

we know that

The distance from the school to her home is 67/100 of a mile

[tex]\frac{67}{100}=0.67\ miles[/tex]

Alecia

we know that

The distance from the school to her home is

3/10 of a mile plus 4/10 of a mile

so

[tex]\frac{3}{10}+\frac{4}{10}=\frac{7}{10}=0.7\ miles[/tex]

Compare the distances

[tex]0.7\ miles>0.67\ miles[/tex]

therefore

Alecia lives farther from school

Final answer:

The answer explains that Georgia lives farther from school than Alecia based on the distances they walked.

Explanation:

Alecia: Walked 3/10 mile from school + 4/10 mile back home = 7/10 mile total distance.

Georgia: Walked 67/100 mile total distance.

Alecia vs. Georgia: Alecia walked 0.7 mile, Georgia walked 0.67 mile. Georgia lives farther from the school as 0.7 > 0.67 mile.

Answer:

y=6x

Step-by-step explanation:

let y be the weight of an object on the earth

let x be the weight of the same object on the moon

Since the weight of an object on earth is 6 times greater than the same thing on the moon, You must multiply the weight of something on the moon by six.

Hope this helped!

Final answer:

The algebraic expression for the weight of an object on Earth given its weight on the Moon, denoted as 'm', is 'W = 6m', where 'W' represents its weight on Earth.

Explanation:

The question is asking us to find an algebraic expression for the weight of an object on Earth given its weight on the Moon.

We know that the gravitational force on Earth is six times greater than on the Moon, which means objects weigh six times more on Earth than on the Moon.

If the weight of an object on the Moon is given as m, then the weight of the same object on Earth, W, would be W = 6m.

In order to see if Tom is staying on his diet you need to add the total calories of the food that he is planning on eating for dinner. The total is 1,344 calories, so if he ate all of it he would not be staying on his diet.

If the shapes are similar, the correspondent sides are in proportion:

[tex]AB\div DE = BC \div EF[/tex]

Let's plug the values and solve for x:

[tex]5x \div 5 = 4 \div x \iff \dfrac{5x}{5}=\dfrac{4}{x}\iff x = \dfrac{4}{x}[/tex]

Multiply both sides by x to get

[tex]x^2=4 \iff x=\pm2[/tex]

The only feasible solution, though, is [tex]x=2[/tex], because it wouldn't make sense to have negative lengths.

The value of x in the similar polygons in the given diagram is: B. x = 2.

Similar polygons have the same shape but different size, thus, the length of their corresponding sides are proportional together and have equal ratio.

In essence, we will have the following ratio:

5x/5 = 4/x

(x)(5x) = (4)(5)

5x² = 20

5x²/5 = 20/5

x² = 4

x = √4

x = 2 (option B)

Answer: option a.

Step-by-step explanation:

The [tex]\lim_{x \to a} f(x)[/tex] give us information about the behavior of the function when the variable x gets closer to the value a. In other words, it tells us to what value y gets closer when x gets closer to the value a.

In this case we are evaluating the limits when:

Answer:

39.473%

Step-by-step explanation:

It is actually fairly simple to get the answer to this. What you can do to find any percentage, is to take the amount done, or whatever it is in the scenario, and divide it by the total. It is like turning it into a fraction, which you can do as well. Turn this into a fraction, and then convert it. 15/38, 15 divided by 38 = 39.473.

Hope this helped ^-^

To find the percentage you have done, divide the number you did by the total number you have to do:

15 / 38 = 0.3947

Multiply that by 100 to get the percentage:

0.3947 x 100 = 39.47% ( Round as needed).

Answer: B) P-a-c.

Step-by-step explanation:

The value of b is P - a - c.

Given,

The perimeter of a triangle is given by the formula P = a + b + c.

We need to solve for b.

The total length of all three sides of a triangle is called the perimeter of the triangle.

It is given by:

P = a + b + c

Where a,b, and c are the sides of the triangle.

We have,

P = a + b + c

Subtracting a on both sides

P - a = a + b + c - a

P - a = b + c

Subtracting c on both sides

P - a - c = b + c - c

P - a - c = b

We get,

b = P  - a - c

Thus the value of b is P - a - c.

Answer:

$27,322.25

Step-by-step explanation:

Final answer:

To find the principal, you can use the formula for compound interest. The principal should be approximately $30,157.40.

Explanation:

To find the principal, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the future value of the investment (which in this case is $45,000)

P is the principal

r is the annual interest rate (which is 5% or 0.05)

n is the number of times interest is compounded per year (monthly compounding means n = 12)

t is the number of years

Using the given values, we have:

45000 = P(1 + 0.05/12)^(12*10)

Solving for P:

P = 45000 / (1 + 0.05/12)^(12*10)

P = 45000 / (1.00416667)^(120)

P ≈ 30157.40

Therefore, Bill must have a principal of approximately $30,157.40.

Then, you can set up the following system of equations:

[tex]\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.[/tex]

You can use the Elimination Method:

- Multiply the first equation by -4.0

- Add both equations.

- Solve for l.

[tex]\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5[/tex]
