The equation that is an example of inverse variation is B none

<h3>How to determine the equations that are direct variation?</h3>

There are several types of variations.

Some of them include:

Direct variation
Joint variation
Inverse variation

Equations that are inverse variation are represented as:

y = k/x

Where k represents the constant of proportionality or variation

From the list of options, none of the equations has the form y = k/x

Hence, the equation that is an example of inverse variation is B none

Answer:

Continuous

Step-by-step explanation:

For the function to be continuous, f(x) must approach the same value as x approaches π from the left as the right.

f(π⁻) = f(π⁺)

lim(x→π) x sin x = lim(x→π) x tan x

π sin π = π tan π

0 = 0

Yes, the function is continuous.

The present value of the money in your savings account is $420, and you're receiving 3% annual interest compounded monthly. What

iragen [17]

Present value: P=$420
Annual interest: i=3%=3/100→i=0.03
Compounded monthly→Number of periods per year: n=12
Future Value: F=?
In two months: t=2

F=P(1+i/n)^t
F=$420(1+0.03/12)^2
F=$420(1+0.0025)^2
F=$420(1.0025)^2
F=$420(1.005006250)
F=$422.1026250
Rounded to two decimal places:
F=$422.10

Answer: Option B. $422.10

Jenna bought 5 reams of paper at the store for a total of $21 . The tax on her purchase was $1 . Write a equation and solve to f

ludmilkaskok [199]

Answer:

The equation needed is $\textrm{Cost of 1 ream of paper} = \frac{20}{5}$

The cost per ream of paper = $4

Step-by-step explanation:

Here, the cost of 5 reams of paper = $ 21

The tax on her purchase = $1

So, the actual cost of 5 reams of paper = Total Cost paid - Tax amount

= $ 21 - $ 1 = $20

So, the actual cost of 5 reams of the paper is $20.

Now, to find out the cost of 1 ream of paper:

$\textrm{Cost of 1 ream of paper} = \frac{\textrm{Total amount paid for 5 reams}}{\textrm{ 5}} \\= \frac{20}{5} = 4$

= $4

Hence, the cost of each ream of paper = $ 4.

A round mirror has a circumference of 87.92 inches. Calculate the area of the mirror.

Zarrin [17]

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=87.92 \end{cases}\implies 87.92=2\pi r\implies \cfrac{87.92}{2\pi }=\boxed{r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2~\hspace{7em}A=\pi \left( \boxed{\frac{87.92}{2\pi }} \right)^2 \\\\\\ A=\pi \cdot \cfrac{87.92^2}{4\pi^2}\implies A=\cfrac{87.92^2}{4\pi }\implies A\approx 615.127998$
