Answer:

The circumference of the wheel is 50.24 inches

Step-by-step explanation:

What I did was divide the diameter by two (Because you need to radi to get the diameter) to be sure of the answer. I then, multiplied the diameter by 3.14 to get 50.24in.

Parallel to y=−3x−2, through (-3, -3)
VashaNatasha [74]

Answer:

Use the formula y-y1=m(x-x1) <---memorize this. The m here is the slope.

Step-by-step explanation:

The equation is in y=mx+b form

Remember mx=slope and b=y-intercept

The question wants you to find the equation that is Parallel to y=-3x-2 and passes through (-3,-3)=(x1,y1)

Parallel=same slope -3x

So now all that's left is to plug into the equation.

y-(-3)=-3(x-(-3))

y+3=-3(x+3) ----> positive - a negative = positive so x-(-x)=x+x

y+3=-3x-9 ----> distribute like terms(subtract 3 from 3 and 3 from -9)

y=-3x-12 - This is your answer, you can check by graphing it.

How can I anwser this ?? help me
lana [24]
Exactly like the previous question you posted.

-3x² - 9x = 0

Divide each side of the equation by -3 :

x² + 3x = 0

Factor the left side:

x (x + 3) = 0

This is true if x=0 or if x=-3 .

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition

  • Left to Right<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)

<u>Algebra II</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-5, -2) → x₁ = -5, y₁ = -2

Point (-3, 4) → x₂ = -3, y₂ = 4

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [Distance Formula]:                                                       \displaystyle d = \sqrt{(-3+5)^2+(4+2)^2}
  2. [√Radical] (Parenthesis) Add:                                                                        \displaystyle d = \sqrt{(2)^2+(6)^2}
  3. [√Radical] Evaluate exponents:                                                                    \displaystyle d = \sqrt{4+36}
  4. [√Radical] Add:                                                                                               \displaystyle d = \sqrt{40}
  5. [√Radical] Simplify:                                                                                         \displaystyle d = 2\sqrt{10}
