Answer:

The slope of the line is 2. It means Jan runs 2 laps every minute.

Step-by-step explanation:

From the given graph it is noticed that the line passing through the points (2,4) and (5,10).

The slope of lines is

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of given line is

$m=\frac{10-4}{5-2}$

$m=\frac{6}{3}$

$m=2$

The slope of the line is 2.

In the given graph x axis represents the time in min and y-axis represents the laps run. The slope defines the number of laps in each minute.

The slope is 2, it means Jan runs 2 laps every minute.

For A for the mean just add them all up which would be which is 430 and divide by the number of numbers there is so 430 divided by 8 = 53.75 and the median order them from least to greatest and find the one in the middle which is 52 and 56 when there's two just add them and then divide it by 2 which is 54

Hope this helped :)

Asap! find the length of the arc

Fantom [35]

Answer:

A. $\frac{21}{4} \pi\ \space\ in$

Step-by-step explanation:

The formula for arc length is:

arc length = rθ

where:

r is the radius = 7 in

θ is the central angle in radians = 135 × $\frac{ \space\ \pi\ }{180}$ = 3/4 π

Substituting these values into the formula:
arc length = 7 in × 3/4 π

= $\frac{21}{4} \pi\ \space\ in$

A circular pen has an area of 64<img src="https://tex.z-dn.net/?f=%20%20%5Cpi%20" id="TexFormula1" title=" \pi " alt=" \pi " a

Allisa [31]

What we know:
shape is circular
Area=64π yr²
Area=πr²
circumference=2πr

In order to find circumference we need r=radius. We can use the area to find r by solving for r using substitution of the information we know above.

Area=πr²
64π=πr² substitution
64π/π=π/πr² multiplicative inverse
64=r²
√64=√r² properties of radicals
8=r We would get two solutions, a positive and negative one but we will only use the positive solution since radius is positive

Circumference=2πr
C=2π(8)=16π yards

Someone please help thank you

Answer:

Slope is your rise over the run so in this case you will start from a pretty point that passes exactly on the line and go up for you rise and over for your run it will be -1/4 it is negative because the line is pointing down and to the left if it is pointing up to the right it is positive
