A liquid shake is being served in a cone shaped container with a base diameter of 8 centimeters and a height of 22 centimeters.

zhuklara [117]

Answer:

The container weighs approximately 28 g.

Step-by-step explanation:

In order to solve this problem we first need to calculate the volume of the container, since it's shaped like a cone we must use the following formula:

volume container = (pi*r²*h)/3

Applying the data from the problem:

r = d / 2 = 8/2 = 4 cm

volume container = [pi*(4)²*22]/3

volume container = (pi*16*22)/3

volume container = (352*pi)/3 = 368.6135 cm³

Since the density is 0.82 g/cm³, we can find the mass of the shake by using the following formula:

density = mass / volume

shake mass = density*volume = 0.82*368.6135 = 302.26307 g

Since the container plus shake weighs 330 grams, then the container alone weighs:

container = 330 -302.26307 = 27.73693 g

The container weighs approximately 28 g.

Given :-

The roots of the function are 5 and -3 .

To Find :-

The Quadratic function .

Answer :-

The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,

$\sf\longrightarrow$ f(x) = ( x - π )(x-∆)

So on using this we have ,

$\sf\longrightarrow$ f(x) = ( x -5)( x -(-3))

$\sf\longrightarrow$ f(x) = (x-5)(x+3)

$\sf\longrightarrow$ f(x) = x(x-5)+3(x-5)

$\sf\longrightarrow$ f(x) = x² -5x +3x -15

$\sf\longrightarrow$ f(x) = x² -2x -15

Hence the required answer is x² -2x -15.

The family car runs out of gas. You have to push it up the driveway into a service station. The ramp is 4 meters long and rises

Sophie [7]

Answer:

Step-by-step explanation:

slope, m = 0.1m/4m = 0.025

Theoretical effort (ignoring friction) = 9000N * 0.025 = 225 N

actual effort = 300 N

efficiency

= potential energy out / actual energy in

= 225 N / 300 N = 0.75
