<span>Graphs can be used to represent periodic data because you can show rise and fall of something and express situations that may be tough to show in writing.</span><span>

In the case that the periodic data is on the range of the function (the y axis)

You can use functions to represent periodic data:

example y=sin(x)</span>

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

zzz [600]

Answer:

$\frac{\Delta v}{v}=0.426$

Step-by-step explanation:

you have that the average sped is given by the following formula:

$v(x,t)=\frac{x}{t}$

The uncertainty formula for a division is given by:

$\frac{\Delta v}{v}=\sqrt{(\frac{\Delta x}{x})^2+(\frac{\Delta t}{t})^2}$ (1)

Δv: uncertainty in speed

Δx: uncertainty in the distance = 0.9m

Δt: uncertainty in time = 0.7s

x: distance = 8.1m

t: time = 1.7s

You replace the values of all parameters in the equation (1):

$\frac{\Delta v}{v}=\sqrt{(\frac{0.9}{8.1})^2+(\frac{0.7}{1.7})^2}\\\\\frac{\Delta v}{v}=0.426$

Hence, the relation between the uncertainty in the average velocity is 0.426

Somebody plz plz plz plz tell me how she got divided by 5!!! It’s URGENT

mezya [45]

When we're finding the mean we add all the numbers then we DIVIDE THE AMOUNT OF NUMBERS. In this case, we have to divide by 5 because that's the amount of numbers there are.
