It would be 82 or 54

Because 72-18=54%
OR 100-18 would be =82

Left to Right

Algebra II

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-2, 3)

Point (9, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(9+2)^2+(3-3)^2}$
Add/Subtract: $d = \sqrt{(11)^2+(0)^2}$
Simplify: $d = \sqrt{(11)^2}$
Simplify: $d = 11$

2. Find the simple interest. P=$90300, R=8.7%, T=2

ZanzabumX [31]

Answer:

$15,712.20

Step-by-step explanation:

First you convert the percentage to decimal form out of 100 (which you divide)

8.7%/100 = 0.087

A = P(1 + rt)

A = $90,300(1 + 0.087 * 2) ( * = multiplication)

I = $106,012.20 - $90,300= $15,712.20

Which you should get $15,712.20

Hope this helps!

Undercoverage might lead to bias in this study due to the risk of collecting data from a small number of people who feel strongly about the research study in this scenario.

<h3>What is Undercoverage bias?</h3>

This refers to a type of sampling bias which occurs when the research population aren't adequately represented in the study.

This type of sampling involves getting data from a selected few people who may have the same opinion or view about the study which doesn't depict the true representation of the population.

This makes the study to be biased which is why undercoverage is usually avoided when conducting a research.

The function c(x) = 0.5x+70 represents the cost c (in dollars) of renting a truck from a moving company, where x is the number o

tigry1 [53]

Step-by-step explanation:

the given function: $c(x) = 0.5x+70.$

Where C = cost (in dollars) and x is the number of miles you drive the truck.

when we compare the given function by slope- the intercept form y=mx+b, what we get is

Slope m = 0.5 whose fraction can be written as $\frac{1}{2}$

And y-intercept b =70.

for us to be able to graph it, we need to plot y-intercept from 70 and then plot some more points by applying or increasing the points by $\frac{1}{2}$

the shaded lines on the graph indicates the given function.

cost is at $70 for 0 number of miles. travelled.

Thus;

the Domain: x≥0 and Range : $C(x)$ ≥ $70$
