Answer:

Volume of a cone is V = (1/3) of (pi)(radius^2)(height)

So (3.14)(36)(9) = 1017.36

Then divide by three.

1017.36 / 3 = 339.12

<u>V = 339.12</u>

A rock is thrown from the side of a ledge. The height (in feet), x seconds after the toss is modeled by: h(x) = -3(x-4)^2+79 How
julia-pushkina [17]

The rock lands on the graound when h(x) = 0:

h(x)=-3(x-4)^2+79=0-3(x-4)^2=-79

Dividing both sides by -3 gives

(x-4)^2=\frac{79}{3}

Taking the square root of both sides gives

x-4=\sqrt[]{\frac{79}{3}}

Finally, adding 4 to both sides gives

x=\sqrt[]{\frac{79}{3}}+4

converting to a decimal form gives

x=9.1

Hence, the rock lands on the ground after 9.1 s.

Can someone help with any of these please?

1. X1 Y1. X2, Y2

(-1,-6). ( -4,3)

Formula for slope which is m

Y2 -Y1 divide by X2-X1

3- -6/ -4 - -1= 9/-3= -3

So M = -3

Y=mx+b

-6= -3 (-1) +b

-6= 3+b

-3=-3

-9=b

Answer Y= -3x-9

2. X, Y

(-5,13)

Y=mx+b

13= 10+b

-10=-10

3=b

Answer C y= mx+b

y=-2x+3

3. (X1,Y1). (X2,Y2)

(3,-4). (5,-6)

Formula for m which is slope y2-y1 / x2-X1

-6- -4 / 5-3 = -2/2= -1 so m = -1

X, Y

(3,-4)

Y=mx+b

-4= -1(3)+b

-4= -3+b

+3=+3

-1. = b

Y= m x+b

-4= (-1) 3 +b

-4= -3. + b

+3= +3

-1. = b

Answer A y= -1x-1
