Some math help please <br> thaank ye

The 'template' for a quadratic function is:
$f(x) = ax^{2}+bx+c$ , where <em>a</em> is the vertical stretch/compression factor.
If the <em>a</em> in f(x) is 2/5, then vertically stretching the function is done by multiplying the function by 2, making:
$g(x) = 2(\frac{2}{5}x^{2}-2)\\g(x)=\frac{4}{5}x^{2}-2$

C=6π yd, find area, answer in terms of π

Elenna [48]

Answer:

$A=9\pi\ yd^2$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference is equal to

$C=2\pi r$

we have

$C=6\pi\ yd$

substitute

$6\pi=2\pi r$

Solve for r

$r=3\ yd$

step 2

Find the area

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=3\ yd$

substitute

$A=\pi (3)^{2}$

$A=9\pi\ yd^2$

A car passes a landmark on a highway traveling at a constant rate of 45 kilometers per hour. Two hours later, a second car passe

Maru [420]

Distance=rate .time

The rate of car 1 is 45km/hr

The rate of 2 car is 70/hr

We know that the second car left two hours after the first

If we let car 1 time =x

Then the time of second car=x-2

When two car reach the landmark,

The distance traveled by each will be the same

Therefore let us set up our equation using the formula for distance

Distance of car 1 = 45*x=45x

Distance of 2 car = 70(x-2)

=70x-140

Set these two equals to each other to designate when they reach the landmark

45x=70x-140

-25x=-140

X=140/25=28/5

=5 3/5

The time traveled by car 2 in the same direction

=v-2=(5 3/5-)-2= 3 3/5 hours

After 3 3/5 hours, car will be overtake car 1
