Ilya [14]

point slope form of a line

y-y1 = m(x-x1)

y-7 = -2 (x-1)

if you want it in slope intercept form

y-7 = -2x +2

add 7 to each side

Answer:

f(x)=-3(x-8)(x+2)

Step-by-step explanation:

f(8)=-3(8-8)(8+2)=-3×0×10=0

f(-2)=-3(-2-8)(-2+2)=-3×(-10)×0=0

f(0)=-3×(0+8)×(0+2)=-3×8×2=-48

GEOMETRY AID URGENT?

weeeeeb [17]

Lets assume center point of circle as O

OD is the radius of circle . so OD is also 7

All the sides of the triangle are equal . so angle at the center O is 60 degree.

radius = 7

Length of arc CD = $\frac{theta}{360} * 2*\pi*r$

= $\frac{60}{360} * 2*\pi*7$

= $\frac{1}{6} * 2*\pi*7$

= $\frac{7\pi}{3}$
