Answer:

Correct answer is option C

Step-by-step explanation:

Given are 4 graphs and we have to select the graph that has a maximum

at (-4,2)

All the graphs seem to be that of a parabola

The curve has maximum only when it is open downward.

Hence Option a and option b cannot be correct as these have a minimum and open upward

Option C and option D are both open downward

Of these, we find that only C graph has the maximum at (-4,2)

D is wrong because max is at (4,2)

So only correct option is option c

Answer:

<h2>The circumference is multipled by 4.</h2>

Step-by-step explanation:

The formula of an area of a circle"

$A=\pi r^2$

The formula of a circumference of a circle:

$C=2\pi r$

The area multipled by 16:

$16A=16\pi r^2\\\\16A=\pi(4^2r^2)\\\\16A=\pi(4r)^2$

The radius has increased fourfold, therefore:

$C'=2\pi(4r)=4(2\pi r)=4C$

The circumference is multipled by 4.

You can calculate the area and check the circumference:

$r=11.6\ in\\\\A=\pi(11.6)^2=132.56\pi\\\\16A=(16)(134.56\pi)=2152.96\pi\ in^2$

Calculate the radius:

$\pi r^2=2152.96\pi$ <em>divide both sides by π</em>

$r^2=2152.96\to r=\sqrt{2152.96}\\\\r=46.4\ in$

Calculate the circumference of both circles:

$r=11.6\ in\\\\C=2\pi(11.6)=23.2\pi\ in$

$r=46.4\ in\\\\C'=2\pi(46.4)=92.8\pi\ in$

$\dfrac{C'}{C}=\dfrac{92.8\pi}{23.2\pi}=4\to C'=4C$

What is the difference in the number of calories in a

Aleonysh [2.5K]

Answer:

C)265

Step-by-step explanation:

To find the median you list all the numbers in order from least to greatest. The number in the middle is the median.

In this case there are two middle number so you have to add them together then devide them by 2.

700, 740, <u>810, 900</u>, 1050, 1120.

810 + 900 = 1,710

1,710/2 = 855.

Your median is 855.

To find the difference you just subtract the two numbers.

1,120-855= 265.
