Consider a circle whose size can vary. Let r represent the radius of the circle (in cm) and let C represent the circumference of

the circle (in cm). Suppose the function g determines the radius of the circle in cm, r, given its circumference in cm, C. Write a function formula for g.

Answer:

g(C)=\frac{C}{2\pi}

Step-by-step explanation:

Let r represent the radius of the circle (in cm) and

let C represent the circumference of the circle (in cm).

First solve the equation for 'r' using circumference formula

Circumference of circle formula is C= 2\pi r

Solve for r, divide both sides by 2pi

r=\frac{C}{2\pi}

the function g determines the radius of the circle in cm

So we replace 'r' with g(C), where C is the circumference

g(C)=\frac{C}{2\pi}

How do I answer this question
viva [34]

\text{The formula of a circle with a center (h; k) and a radius r}\\\\(x-h)^2+(y-k)^2=r^2\\\\x^2+y^2=4\to (x-0)^2+(y-0)^2=2^2\\\\\text{therefore we have the circle with a center (0; 0) and a radius 2}\\\\x-y=1\ \ \ |-x\\-y=1-x\ \ \ |\cdot(-1)\\y=x-1\\\\for\ x=0\to y=0-1=-1\to(0;-1)\\for\ x=1\to y=1-1=0\to(1;\ 0)\\\\\text{Look at the picture}

Marc is growing three bean plants as part of a science experiment. Plant A is 1/3 inch tall. Plant B is 3/4inch tall. Plant C is
Mrrafil [7]

Answer:

From shortest to tallest the answer is Plant A, Plant B, and then Plant C.

Step-by-step explanation:

To find this answer I first converted the fractions into decimals.

Plant A: 1/3 inch = 0.33 inch

Plant B: 3/4 inch = 0.75 inch

Plant C: 5/6 inch = 0.83 inch

Therefore, the answer is Plant A, Plant B, Plant C from shortest to tallest.

What is the true solution to l n 20 + l n 5 = 2 l n x x = 5 x = 10 x = 50 x = 100
Pani-rosa [81]

Answer:

x = 10

Step-by-step explanation:

l n 20 + l n 5 = 2 l n x

ln (20×5) = ln x²

ln(100) = lnx²

100 = x²

x = +/- 10

Since logs of negative numebrs don't exist, we reject -10
