Answer:

y = 7x

Step-by-step explanation:

Complete question:

Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)

The equation of a line in point-slope form is expressed as;

y - y0 = m(x-x0)

(x0, y0) = (0,0)

Given the equation of the line as 7x - y = -7;

Rewrite and get the slope

-y = -7x - 7

y = 7x+7

Get the slope

mx = 7x

m = 7

Substitute into the equation

y - 0 = 7(x - 0)

y = 7x

Hence the required equation is y = 7x

Explanation:

We'll use the remainder theorem.

This theorem says that if you divide p(x) over (x-k), then the remainder is p(k).

We have p(x) = x^3 + 3x^2 - 16x - 48 and the denominator is one of the four choices A through D.

Let's go through each of them until we find the answer.

-----------------

For choice A, we have x+2 which is the same as x-(-2). It matches with x-k to show that k = -2.

Plug k = -2 into p(x) to get

p(x) = x^3 + 3x^2 - 16x - 48

p(-2) = (-2)^3 + 3(-2)^2 - 16(-2) - 48

p(-2) = -12

The remainder is -12, which is not 0 like we're after. We can cross A off the list.

-----------------

We'll follow the same ideas for choices B through D

For choice B, we plug in k = 4 because x-4 matches with x-k to show that k = 4.

p(x) = x^3 + 3x^2 - 16x - 48

p(4) = (4)^3 + 3(4)^2 - 16(4) - 48

p(4) = 0

We end up with a remainder of 0, so we can stop here. Dividing (x^3+3x^2-16x-48) all over (x-4) leads to some quotient and a remainder of 0.

Put another way: (x-4) is a factor of x^3+3x^2-16x-48

Answer:

The equation for the trend line is y=2x-10

Answer:

3 bottles

Step-by-step explanation:

1 bottle -- $1.20

x bottles -- 3.60 (total cost)

Therefore, number of bottles -- (3.60/1.20) = 3

She bought 3 bottles.

Answer:

The nth term is 35+ 7(n-1) or can be written 28 + 7n

Step-by-step explanation:

This is an arithmetic sequence, where each term equals the previous term, with a constant value added.

T1 = 35

T2 = 42 = T1 + 7 = 35 + 7

T3 = 49 = T2+ 7 = 35 + 7 + 7 = 35 + 2x7

…

The nth term is equal to 35 + 7X(n-1)

Answer:

218

Step-by-step explanation:

first find the area of the circle-

[tex]A=\pi r^{2} \\A=\pi 10^{2} \\A=100\pi \\A=314[/tex]

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

[tex]a^{2} +b^{2} =c^{2} \\a^{2} +16^{2} =20^{2} \\a^{2} +256=400\\a^{2} =144\\a=12[/tex]

Now I know the height is 12. Find the area of the triangle

[tex]A=\frac{1}{2} bh\\A=\frac{1}{2} (16)(20)\\A=96[/tex]

subtract the area of the triangle from the area of the circle

314-96=218

Answer:

$17

Step-by-step explanation:

We are assuming that snow shovels for 10 families means 10 shovel in total. If the manager is offering $2 discount per shovel, and there are ten shovels, then that is a 20 dollar discount. 85, the cost after discount, plus 20 is 105. 105/10=10.5. Your family is offering two pay for two shovels, so the total for you would come to $21, but there is the $2 discount, so subtract 4 dollars, and you have $17.

Answer:

There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

Reject [tex]H_0\ at\ 5%[/tex] level of significance

Step-by-step explanation:

From the question we are told that:

Sample size 1 [tex]n_1=15[/tex]

Spacing 1 [tex]s_1=8[/tex]

Mean 1 [tex]\=x_1=8.48[/tex]

Standard deviation 1 [tex]\sigma_1=0.96 kPa[/tex]

Sample size 2 [tex]n_2=16[/tex]

Spacing 2 [tex]s_2=6[/tex]

Mean 1 [tex]\=x_1=9.93[/tex]

Standard deviation 1[tex]\sigma_1=1.02 kPa[/tex]

Generally the hypothesis is mathematically given as

Null [tex]H_0:\mu_1-\mu_2[/tex]

Alternative [tex]H_a:\mu_1\mu_2[/tex]

Generally the equation for pooled estimate is mathematically given by

  [tex]S=\sqrt{\frac{(n_1-1)\sigma_1^2+(n_2-1)\sigma_2^2}{n_1+n_2-2} }[/tex]

Therefore

  [tex]S=\sqrt{\frac{(15-1)0.96^2+(16-1)1.02^2}{15+15-2} }[/tex]

 [tex]S=0.9905[/tex]

Generally the equation for test statistics is mathematically given by

 [tex]t=\frac{\=x_1+\=x_2}{S\sqrt{\frac{1}{n _1}+\frac{1}{n_2}}}[/tex]

 [tex]t=\frac{\=8.48-9.93}{0.9905\sqrt{\frac{1}{15}+\frac{1}{15}}}[/tex]

 [tex]t=-4.00091[/tex]

Therefore From table

 [tex]P value=P(t_{15+15-2}=4.00091)[/tex]

 [tex]P value=0.00041918[/tex]

 [tex]P<0.0005[/tex]

Therefore

There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

Reject [tex]H_0\ at\ 5%[/tex] level of significance
