In our equation, the Y value is the dependent variable and the X is the independent variable. The amount of pounds lost depends on the number weeks on a diet. To get the actual pounds Steve was able to lose in 4 weeks, we have:

Y = 1.8x + 1.2
Y = 1.8(4) + 1.2
Y = 8.4 pounds

Please answer quickly! ill mark u brainliest!

Ierofanga [76]

Answer:

Step-by-step explanation:

f(x) = 2x - 5

When x = -2,

f(-2) = 2*(-2) - 5 = - 4-5 = (-9)

When x = 0,

f(0) = 2*0 - 5 = -5

When x = 5,

f(5) = 2*5 - 5 = 10 - 5 = 5

x -2 0 5

y -9 -5 5

soda is sold in aluminum cans that measure 6 inches in height and 2 inches in diameter. how many cubic inches of soda are contai

Gekata [30.6K]

Answer:

18.84 cubic inches

Step-by-step explanation:

Height of aluminum cans = 6 inches

Diameter of can = 2 inches

we know that diameter is twice of radius

So,

Diameter of can = 2 inches = 2* radius of can

radius of can = 2 inches/2 = 1 inches

We also know that volume of any cylindrical object is given by

volume of cylinder = $\pi r^2 h$

where h is height of cylinder

and r is radius of cylinder

___________________________________

Amount of soda in can will be equal to volume of can

$volume \ of \ can = \pi r^2h\\\\ volume \ of \ can = 3.14*1^2* 6 \ ( \pi= 3.14)volume \ of \ can = 18.84 \\\\$

Thus, 18.84 cubic inches of soda are contained in the given full can.
