1.M=1

2.3/5

3.(NO SOLUTION)

4.0

5.1/2 =0.5

Step-by-step explanation:

Y=mx+b

M=(Y2)+(y1)/(x2)+(x1)

1. x1  y1    x2   y2

    (-4 , -5) , (3 , 4)

Slope:

M=(4)+(-5)/(3)+(-4)

=-1/-1= 1

2. x1  y1    x2   y2

    (0 , -2) , (5, -1)

Slope:

M=(-1)+(-2)/(5)+(0)

=-3/5

3. x1  y1    x2   y2

    (-5 , -1) , (5 , -3)

Slope:

M=(-3)+(-1)/(5)+(-5)

=- 4/0=(NO SOLUTION)

4. x1  y1    x2   y2

    (-5, -5) (-1, 5)

Slope:

M=(5)+(-5)/(-1)+(-5)

= 0/-6 =0

5. x1  y1    x2   y2

    (-2, 0) (4, 1)

Slope:

M=(1)+(0)/(4)+(-2)

= 1/2 =0.5

Answer:

   = 147.1369 pi

Step-by-step explanation:

The diameter is 24.26

The radius is d/2 = 24.26/2 =12.13

The area of a circle is

A = pi r^2

   = pi (12.13)^2

   = 147.1369 pi

Answer:

147.1369

Step-by-step explanation:

i think im wrong not sure. also the answer is not rounded.

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

x^1/3*x^1/5

Apply exponent rule:

x^1/3*x^1/5= x^1/3+1/5

x^1/3+1/5

Add the fractions:

LCM of 3, 5 is 15

5/15 + 3/15

Since the denominators are equal combine the fractions:

5+3/15

Add the numbers 5+3:

5+3= 8

8/15

x^8/15

Your Answer Is x^8/15

Answer:

The inverse is

f^-1(x) = (1/√2)x^¼

And it is a function

Step-by-step explanation:

Given f(x) = 4x^4

Let y = f(x), so that

y = 4x^4

Then dividing both sides by 4

x^4 = y/4

Taking the fourth root of both sides

x = (y/4)^¼

x = (1/√2)y^¼ = f^-1(y)

Put y = x

y = (1/√2)x^¼ = f^-1(x)

This is the inverse.

f^-1(x) is a function.

Answer:

-4 ± 2*sqrt(3)

Step-by-step explanation:

Well I'm not quite sure as to what the x= equations are, but for the solution to this quadratic I just used the quadratic formula. This gave me -8 ± sqrt(48)/2, which can be simplified to -4 ± 2 * sqrt(3). Hope this helps :)

Answer:

The amount of carbon in the trees and in the deer . . .

A) has increased.

Explanation:

Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.

Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.

Step-by-step explanation:

Answer:

716in³

Step-by-step explanation:

The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.

For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about 235.62 cubic inches.

For the volume of the other prism, we simply have to do length times height times width, or 6·8·10. That is equal to 480 cubic inches, which is the volume of that prism.

To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.

235.62+480= 715.62in³, or about 716in³.

Hope this helps.

Answer:

110in2

Step-by-step explanation:

Area = (base1 + base2 ) * height /2

        = ( 9 + 13) *10 /2 = 110in2

Answers:

110in^2

Step-by-step explanation:

area pf rectangle=l×w

=9in×10in

=90in^2

area of 1st triangle

A=bh/2

=2in×10in/2

=20in^2/2

=10in^2

area of 2nd triangle=10in^2

Area of trapezoid =90in^2+10in^2+10in^2

=11in^2

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours

Step-by-step explanation:

All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.

Part 1: Garden Snail

= [tex]\frac{2,800}{0.029}[/tex]

≈ 96,551.7

Part 2: North American X-15

= [tex]\frac{2,800}{4,520}[/tex]

≈ 0.6

These are the answer!
