Answer:

$6.5\pi\ in$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=3\frac{1}{4}\ in$

Convert to an improper fraction

$r=3\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}\ in$

substitute

$C=2\pi(\frac{13}{4})$

$C=\frac{13}{2}\pi=6.5\pi\ in$

2/3 minus 5/8<br> what’s the answer

Rama09 [41]

Hey there!

$\frac{2}{3}$ $-$ $\frac{5}{8}$
Change the " $subtract$ " symbol to a $addition$ symbol
$\frac{2}{3} + \frac{-5}{8}$
$(-5)(3)$ $= -15$
$2(8)$ $=16$
$3$ $(8)$ $=$ $24$
$\frac{16}{24} + \frac{-15}{24}$
Add " $16 + (-15)$ " together
$\frac{16+ (-15)}{24}$
$16 + (-15)$ $= 1$
$24$ $= 24$
Therefore, $\boxed{Answer: \frac{1}{24} }$

Good luck on your assignment and enjoy your day!

Which of these functions had a greater rate of change than the function graphed below, and why?

Mrac [35]

Answer:

C

Step-by-step explanation:

When we talk of rate of change, we talk of the slope of the line

If we had a line;

y = mx + b

m is the slope ( which is the rate of change)

To get the slope of the line, we select any two points on the line and apply the slope formula

m = y2-y1/x2-x1

let us take points (0,0) and (3,9)

m = 9-0/3-0 = 9/3 = 3

The slope here is 3

so from the option, we can see that the third option is the correct answer
