Find the distance between the two points in simplest radical form.
(-9, 8) and (-3,-1)
Answer:

Answers

Answer 1

Answer:

3[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)

d = [tex]\sqrt{(-3-(-9))^2+(-1-8)^2}[/tex]

  = [tex]\sqrt{(-3+9)^2+(-9)^2}[/tex]

  = [tex]\sqrt{6^2+81}[/tex]

   = [tex]\sqrt{36+81}[/tex]

   = [tex]\sqrt{117}[/tex]

   = [tex]\sqrt{9(13)}[/tex]

   = [tex]\sqrt{9}[/tex] × [tex]\sqrt{13}[/tex]

   = 3[tex]\sqrt{13}[/tex]

Answers

I am guessing that you mean 2cos2(45° - A) = 1 + sin2A

According to a double angle identity, 2cos2θ - 1 = cos(2θ)

So, 2cos2(45° - A) - 1

= cos (90° - 2A) =cos90°cos2A + sin90°sin2A = (0)cos2A + (1)sin2A = sin2

Thus, 2cos2(45° -A ) = 1 + sin2A

Ashley is bagging 32 pumpkin muffins and 28 banana muffins for
some friends. Each bag will hold only one type of muffin. Each bag
will hold the same number of muffins. What is the greatest number
of muffins she can put in each bag? How many bags of each type
of muffin will there be?

Answers

the greatest amount of muffins she can put in each bag is 4 because both 32 and 28 are divisible by 4

if she chooses to put 4 in each bag there will be 8 bags of pumpkin muffins and 7 bags of banana muffins

Perimeter of Triangle Please. Thank you ASAP

Answers

Step-by-step explanation:

The perimeter of a parallelogram is twice the sum of the length of a longer and a shorter side.

The length can be evaluated by the distance formula between two points (x_1,y_1), (x_2, y_2)

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For the longer side,

[tex]d=\sqrt{(7-(-4))^2+(3-2)^2}=\sqrt{122}[/tex]

or the shorter side,

[tex]d=\sqrt{(7-6)^2+(3-(-2))^2}=\sqrt{26}[/tex]

Therefore, the perimeter is given by,

[tex]2(\sqrt{122}+\sqrt{26})\approx254.2[/tex]

Answer:

B

Step-by-step explanation:

The steps in the original function of f of B are

1. multiply by 2

2. subtract 9

Then the steps of the inverse equation would be

1. add 9

2. divide by 2

And this is what we see here. G is actually the inverse of f. Therefore B is the correct answer. If you repeat the same process for the other answers you'll find that it doesn't actually make an inverse.

You can also graph these to see whether or not its an inverse.

YZ=60

Step-by-step explanation:

8x = 81 -1

8x =80

x = 80/8

if 3x+ 5y +4z =0 , prove that 27x³ +125y³ +64z³=180xyz​

Answers

Answer:

Use the following identity:

a³ + b³ + c³ = 3abc if a + b + c = 0

Substitute:

a = 3x, b = 5y, c = 4z

and get:

(3x)³ + (5y)³ + (4z)³ = 3(3x)(5y)(4z)27x³ + 125y³ + 64z³ = 180xyz

We know

If a+b+c=0

[tex]\boxed{\sf a^3+b^3+c^3=3abc}[/tex]

[tex]\\ \sf\longmapsto 3x^3+5y^3+4z^3=3(3x)(5y)(4z)[/tex]

42 = -48 + 3r
This is some random stuff the teacher didn’t teach us about

Answers

Answer:

[tex]42 = - 48 + 3r[/tex]

add 48 to either sides:

[tex]42 + 48 = ( - 48 + 3r) + 48 \\ 90 = 3r \\3r = 90[/tex]

divide all sides by 3:

[tex] \frac{3r}{3} = \frac{90}{3} \\ \\ { \boxed{ \boxed{r = 30}}}[/tex]

Answer:

r = 30

Step-by-step explanation:

42 = -48 + 3r

First, we will add 48 to both sides so that r can be isolated

42 + 48 = -48 + 48 + 3r

Then, we will add

90 = 3r

Then to isolate r, we have to get rid of the 3To get rid of the 3, we will divide by 3 on both sides

[tex]\frac{90}{3} =\frac{3r}{3}[/tex]

Then, divide

30 = r
