Answer:

1442 $yd^{3}$ (nearest whole number)

Step-by-step explanation:

The volume of a cone is given by

$V=\frac{1}{3} \pi r^{2} h$

We are given both the radius (r) and height (h). Sub these values into their respective variables,

$V=\frac{1}{3} \pi (9)^{2} (17)$

Put this into the calculator and you will get V = 1441.9910....

Rounding this to the nearest whole number would be 1442 $yd^{3}$

Hope this helped!!

Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance

maks197457 [2]

Answer:

The uncertainty in the average speed is 0.134 meters per second.

Step-by-step explanation:

Let be $v(t, x) =\frac{x}{t}$ the average speed function, we calculate the uncertainty in the average speed by total differentials, which is in this case:

$\Delta v = \frac{\partial v}{\partial x}\cdot \Delta x+\frac{\partial v}{\partial t}\cdot \Delta t$

Where:

$\Delta v$ - Uncertainty in the average speed, measured in meters per second.

$\frac{\partial v}{\partial x}$ - Partial derivative of the average speed function with respect to distance, measured in $s^{-1}$ .

$\frac{\partial v}{\partial t}$ - Partial derivative of the average speed function with respect to time, measured in meters per square second.

$\Delta x$ - Uncertainty in distance, measured in meters.

$\Delta t$ - Uncertainty in time, measured in seconds.

Partial derivatives are, respectively:

$\frac{\partial v}{\partial x} = \frac{1}{t}$ , $\frac{\partial v}{\partial t} = - \frac{x}{t^{2}}$

Then, the total differential expression is expanded as:

$\Delta v = \frac{\Delta x}{t}-\frac{x\cdot \Delta t}{t^{2}}$

If we get that $\Delta x = 2.3\,m$ , $t = 6.3\,s$ , $x = 6.1\,m$ and $\Delta t = 1.5\,s$ , the uncertainty in the average speed is:

$\Delta v = \frac{2.3\,m}{6.3\,m}-\frac{(6.1\,m)\cdot (1.5\,s)}{(6.3\,s)^{2}}$

$\Delta v = 0.134\,\frac{m}{s}$

The uncertainty in the average speed is 0.134 meters per second.

Joe started to save money to purchase a new game console. His savings at the end of the first week included a jar of 468 nickels

Jet001 [13]

The system of equations that can be used to determine the number of nickels and dimes is:

x + y = 468

0.05x + 0.01y = 34.40

Where:

x = number of nickels

y = number of dimes

The equation that can be used to determine the number of nickels and dimes are known as simultaneous equations. Both equations have to be solved together in order to determine the required values.

Does anyone know what graph is correct?

VashaNatasha [74]

First graph is the correct one.

when x= 1

y=f(x) = -√1 = -1

when x= 2

y= -√2

Jack says 0.90 is between 0.9 and 0.91. Is he correct? Explain.

OleMash [197]

Well, 0.90 is actually equal to 0.9. It is less than 0.91 and equal to 0.9 so that means it is not correct.

I hope this helps:)
