Answer:

x = -6 x= -3

Step-by-step explanation:

f(x) = x^2+9x+18

Set equal to 0 to find the zeros

0 = x^2+9x+18

Factor, what numbers multiply to 18 and add to 9

6*3 =18

6+3=9

0= (x+6) (x+3)

Using the zero product property

x+6 =0 x+3 =0

x = -6 x= -3

Circle F has a diameter of 36m and = 240o. Find the length of . Leave your answer in terms of pi.

andrezito [222]

Answer:

So, the arc length is $24\pi$

Step-by-step explanation:

We are given

diameter =36m

so, we can find radius

$r=\frac{36}{2}=18m$

and angle as

$\theta=240$

Since, it is in degree

so, we can change it in radian

$\theta=240\times \frac{\pi}{180}$

$\theta=\frac{4\pi}{3}$

now, we can find arc length

$L=r\times \theta$

now, we can plug values

$L=18\times \frac{4\pi}{3}$

$L=24\pi$

Step-by-step explanation:

y = -x + 12

Replace x with y.

x = -y + 12

Solve for y, x = -y + 12

= 12 - x
