<h3>What is division?</h3>

Division means the separation of something into different parts, sharing of something among different people, places, etc.

Alex has 1/3 of a candy bar.

He wants to share what he has left of his candy bar with his 2 friends so that all three of them get equal portions.

Then the fraction of the candy bar will each kid get will be

\rightarrow \dfrac{1/3}{3}\\\\\rightarrow  \dfrac{1}{3\times3}\\\\\rightarrow  \dfrac{1}{9}

Find the radius of the circle whose equation is x^2 + y^2 = 4.
KATRIN_1 [288]

Answer:

Radius of the given circle is r = 2.

Step-by-step explanation:

Given equation of the circle is x^2 + y^2 = 4.

Now we need to find the radius of the given circle x^2 + y^2 = 4.

To find that let's compare with the formula of the circle with is x^2 + y^2 = r^2, where r is the radius.

We get r^2 = 4

take square root of both sides.

r=2

Hence radius of the given circle is r = 2.

A car travels down a highway at 25 m/s. An observer stands 150 m from the highway.
makvit [3.9K]
Let x be the distance (in feet) along the road that the car has traveled and h be the distance (in feet) between the car and the observer.

(a) Before the car passes the observer, we have dh/dt < 0; after it passes, we have dh/dt > 0. So at the instant it passes the observer we have dh/dt = 0, given that dh/dt varies continuously since the car travels at a constant velocity.

PLEASE HELP ME SOLVE THIS Find all x-values for which f ( x ) = 2 for the function below.
alisha [4.7K]

Answer:

<h3>x = -3</h3>

Step-by-step explanation:

First let us get the equation of the coordinates

y-y0 = m(x-x0)

Using the coordinates ( - 3, 2 ), ( - 1, 0 )

m = 0-2/-1-(-3)

m = -2/2

m = -1

Substitute m = -1 and (-1, 0) into the formula

y - 0 = -1(x+1)

y = -x-1

f(x) = -x-1

Since f(x) = 2

2 = -x-1

-x = 2+1

-x = 3

x = -3

Hence the value of x is -3
