Find the exact circumference, in terms of , of a circle with the given radius.

1 answer:

8 0

By definition, when we say circumference, this is the measure or the distance around the circle. To find the circumference of a circle we use this formula. C = π x the diameter of the circle or C = 2πr .
Given that the radius is x/2 miles, let us plug in the values.
So C = 2(3.14)(x/2)
C = 6.28 (x/2)
C= 6.28x/2
C = 3.14x
So the circumference of the given circle above would be 3.14x miles. Hope this answer helps.

71° the line thats horizontal through center splits the angles. so you take the angle on the opposite side and subtract it from 180° to get the bottom angle. and that angle is equal to x

The solutions for $-5 +2x^{2} = -6x$ is option 3. $x= \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .$

Step-by-step explanation:

Step 1:

First, we must bring the equation to the form of $ax^{2} +bx +c =0.$

So $-5 +2x^{2} = -6x$ becomes $2x^{2} +6x-5=0.$

The value of a is the coefficient of the $x^{2}$ term, the value of b is the coefficient of x term and c is the coefficient of the constant term.

Comparing the above equation to $ax^{2} +bx +c =0,$ we get $a = 2, b = 6,$ and $c=-5.$

We have the formula $x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}.$

Step 2:

By substituting the known values, we get

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} =\frac{-6 \pm \sqrt{6^{2}-4 (2)(-5)}}{2 (2)}.$

$\frac{-6 \pm \sqrt{6^{2}-4 (2)(-5)}}{2 (2)} = \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .$

This is the third option.

A gas station charges $2.19 per gallon of gas. use function notation to describe the relationship between the total cost c(g) an

Butoxors [25]

For this case, the first thing we must do is define a variable:
g: number of gallons of gas.
c (g): total cost.
We then have a linear function of the form:
c (g) = 2.19 * g
Answer:
A function notation to describe the relationship between the total cost c (g) and the number of gallons purchased is:
c (g) = 2.19 * g
