Answer:

Step-by-step explanation:

C=pi (d)      circumference = pi (3.14) times the diameter which is 10, because the radius 5 and diameter is twice the radius..........

you can also use Formula C=2pi r which will give you the same answer.

31.4 cm for orange circle

the diameter (all the way through the center of the circle) for blue circle would be 20

C=pi (d)   3.14 times 20=  62.8 cm for blue circle

Answer:

The Orange circle is: 78.5 cm

And The Blue circle is 314.2 cm

Step-by-step explanation:

By taking the formula r^2(pi), and filling it in with the radius for the orange circle you will get 78.5. For the blue circle the radius would be the orange's radius combined with the rim given. Using the same formula you will get 314.2.

Answer:

3

Step-by-step explanation:

To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).

Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).

So we have: (87-45) / (29-15)

This can be simplified to: 42/14, or 3.

Let me know if this helps!

horrorfan [7]

Answer:

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.

Since it's a decimal it can not be an integer.

If 5-y^2=x^2 then find d^2y/dx^2 at the point (2, 1) in simplest form. ​
ratelena [41]

Answer:

y"(2, 1) = -5

Step-by-step explanation:

Step 1: Define implicit differentiation

5 - y² = x²

Step 2: Find dy/dx

  1. Take implicit differentiation: -2yy' = 2x
  2. Isolate y': y' = 2x/-2y
  3. Isolate y': y' = -x/y

Step 3: Find d²y/dx²

  1. Quotient Rule: y'' = [y(-1) - y'(-x)] / y²
  2. Substitute y': y" = [-y - (-x/y)(-x)] / y²
  3. Simplify: y" = [-y - x²/y] / y²
  4. Multiply top/bottom by y: y" = (-y² - x²) / y³
  5. Factor negative: y" = -(y² + x²) / y³

Step 4: Substitute and Evaluate

y"(2, 1) = -(1² + 2²) / 1³

y"(2, 1) = -(1 + 4) / 1

y"(2, 1) = -5/1

y"(2, 1) = -5

PLS HELP TIMED EXAM plsss
zimovet [89]
Might be 134 because since angle 2 and 8 are lined up like that it is same side exterior angles which means they are supplementary from each other so they will equal 180. So I did 180-46 to get 134, I’m not sure if I’m correct

6m-2 = 2m+6<br><br><br>answer pls​
Mekhanik [1.2K]

Answer:

m=2   :)

Step-by-step explanation:

Let's solve your equation step-by-step.

6m−2=2m+6

Step 1: Subtract 2m from both sides.

6m−2−2m=2m+6−2m

4m−2=6

Step 2: Add 2 to both sides.

4m−2+2=6+2

4m=8

Step 3: Divide both sides by 4.

4m /4 = 8/ 4

m=2
