What is the relative size of (how many times as large) a circle's' circumference C to its diameter, d

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
4 0

Answer:

The circumference is pi times larger than the diameter of a circle.

Step-by-step explanation:

The formula of the circumference of a circle is

C = 2(pi)r = (pi)d

C = (pi)d

To find the ratio of the circumference to the diameter, divide both sides of the equation by d.

C/d = pi

The circumference is pi times larger than the diameter of a circle.

What is the inverse of the function g(x)=-\dfrac{2}{3}x-5g(x)=− 3 2 ​ x−5g, left parenthesis, x, right parenthesis, equals, minu
Semenov [28]

Answer:

g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}

Step-by-step explanation:

Given function,

g(x) = -\frac{2}{3}x-5

Step 1 : Replace g(x) by y:

y = -\frac{2}{3}x-5

Step 2 : Swap x and y:

x = -\frac{2}{3}y-5

Step 3 : Solve the equation for y ( isolate y in the left side ):

x +\frac{2}{3}y=-5

     \frac{2}{3}y=-5-x

      y=\frac{3}{2}(-5-x)

      y=-\frac{15}{2}-\frac{3}{2}x

      y=-\frac{3}{2}x-\frac{15}{2}

Step 4: Replace y by g^{-1}(x):

g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}

Hence, the inverse of the function g(x) is g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}.

Find the roots of the following factored quadratic equation.<br> y= (2x-9) (7x-4)
Marina86 [1]

Answer:

x = 4.5, 4/7

Step-by-step explanation:

To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.
