Answer:

  (0.75, -1)

Step-by-step explanation:

The center of the circle is at the midpoint of any diameter segment. The midpoint formula can be used.

  C = (A +B)/2

  C = ((-1, 1) +(2.5, -3))/2 . . . . fill in A and B

  C = (-1+2.5, 1-3)/2 . . . . . . .  add the coordinates

  C = (1.5, -2)/2 . . . . . . finish the addition; next, divide by 2

  C = (0.75, -1) . . . . . . the center of the circle

from most to least:

i: 1/2, 1/3, 1/7, 1/10

ii: 2/3, 2/5, 2/9, 2/11

iii: 5/6, 3/4, 2/3, 1/2

iv: 4/5, 3/4, 5/8, 1/2

Answer:

(D)

Step-by-step explanation:

If it has a leading coefficient of 1, then it can not (A) or (B) because they have a two in front of it. Next, we can check the roots -2 and 7. -2 goes with (x+2), while 7 goes with (x-7). Therefore, you can already see that the answer is (D). To make sure. let us check the root 5 with multiplicity of 2. 5 goes with (x-5), implying that there must be 2 (x-5)'s. Only (D) satifies that as well, so the answer must be (D).

D on edge

Step-by-step explanation:

the range is about 45

Answer:

stop rushing brat

Step-by-step explanation:

Step-by-step explanation:

Steps to solve "45 is 3 percent of what number?"

We have, 3% × x = 45

or,

3

100

× x = 45

Multiplying both sides by 100 and dividing both sides by 3,

we have x = 45 ×

100

3

x = 1500

If you are using a calculator, simply enter 45×100÷3, which will give you the answer.

Answer:

Step-by-step explanation:

4x² + 28x + 49

4x² + 14x + 14x + 49

2x(2x) + 2x(7) + 7(2x) + 7(7)

2x(2x + 7) + 7(2x + 7)

(2x + 7)(2x + 7)

(2x + 7)²

= 28

Answer:

80 ft

Step-by-step explanation:

if 1 = 20 then 20 is width but ? is length

1=20

2=40

3=60

4=80

since 4 in is length then actual length is 80ft

Answer:

80ft

Answer:

The period of the model is [tex]\frac{3\pi}{4}[/tex] seconds. The period represents the time needed for the function to complete one cycle.

Step-by-step explanation:

Cosine is a trigonometric function and trigonometric functions are characterized by having a periodical behavior. The period is the time needed for the function to cover an angle of [tex]2\pi[/tex] radians. By this approach we find that:

[tex]\frac{8\pi\cdot t}{3} = \frac{2\pi\cdot t}{T}[/tex] (1)

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]T[/tex] - Period, measured in seconds.

Then, we solve (1) for [tex]T[/tex]:

[tex]\frac{8}{3} = \frac{2\pi}{T}[/tex]

[tex]T = \frac{6\pi}{8}\,s[/tex]

[tex]T = \frac{3\pi}{4}\,s[/tex]

The period of the model is [tex]\frac{3\pi}{4}[/tex] seconds. The period represents the time needed for the function to complete one cycle.

To prove that the triangle is scalene, calculate all the lengths of the sides.

The formula for a line like this is basically pythagorean theorem, which is

[tex]p = \sqrt{ {(y2 - y1)}^{2} + {( x2 - x1})^{2} } [/tex]

(x1, y1) and (x2, y2) are the respective vertexes.

Answer:

-18x

Step-by-step explanation:

First step: remove the parentheses.

So, you'll have -3x*6.

multiply the numbers (3 x 6 = 18)

and you'll get -18x.

No

Step-by-step explanation:

I don't think those are equivalent because 7/8 is positive while -7/-8 is negative.

Answer:

See below.

Step-by-step explanation:

It is similar because the order of operations is the same for fractions and for whole numbers.

It is different because when you add or subtract fractions, you need a common denominator. When you deal with whole numbers, there are no denominators.

Answer:

16.

Step-by-step explanation:

What does 75% Off mean? It means 75% of the price is subtracted. So find 75% of 64.

Here is our equation: 75/100 x 64 = 48.

So 48 dollars is going to be subtracted from 64, which gives us 64-48=16.

So the price of the wedding cake during the sale is 16.

Ce clasă ești sa văd daca te pot ajuta

Answer: Choice B) 35.3 degrees

======================================================

Work Shown:

Apply the law of sines

sin(S)/s = sin(R)/r

sin(S)/16 = sin(120)/24

sin(S) = 16*sin(120)/24

sin(S) = 0.57735026918962

S = arcsin(0.57735026918962)

S = 35.2643896827542

S = 35.3

Make sure your calculator is in degree mode.

Step-by-step explanation:

Answer: -48x-16

Step-by-step explanation:

-8-8(6x+1)

So we are going to let the first -8 stand still for a moment and focus on the "-8(6x+1) part. We will solve this using distributive property.

-8 x 6x = -48x

and

-8 x 1 = -8

This is our new problem -8 -48x -8 .

Lets do like terms. Our like terms are (-8) and (-8). And we know -8 -8 = -16.

Now we'll add that to our (-48x) . I hope you can understand this!
