Pepsi [2]

Answer:

B. x = 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

check by substituting each given value of x into the function

x = 0 ⇒ y =  × 0² = 0

hence (0, 0) is correct

x = 2 ⇒ y =  × 4 = 3

hence (2, 4 ) is incorrect

x = 3 ⇒ y =  × 9 = 6  

hence (3, 6 ) is correct

x = 5 ⇒ y =  × 25 = 18  

hence (5, 18 ) is correct

The lateral surface area of a cylinder is given by the formula S= 2πrh. Solve the equation for r.
alukav5142 [94]

Answer:

Well, with the info I have been given I would say; The L.A of a cylinder is SA+=2(pi)(r)(h).

Step-by-step explanation:

SA=Surface Area

LA=Lateral Area

Pi=3.14

R=Radius

H=Height

V=Volume

LA=2*pi*r*h <-- finds the Lateral Area of a cylinder

SA=LA+2*base or SA=2*pi*r*h+2*pi*r^2<-- finds the Surface Area of a cylinder

V=pi*r^2*h<---- Finds volume of the cylinder

monitta

Answer:

z =  \frac{47}{7} = 6 \frac{5}{7}

Step-by-step explanation:

7 =  \frac{40}{z - 1}  \\ 7(z - 1) = 40 \\ 7z - 7 = 40 \\ 7z = 40 + 7 \\ 7z = 47 \\

\boxed{\bold{Answer:{\boxed{\green{\bold{z =  \frac{47}{7} = 6 \frac{5}{7}}}}}}}
