Answer: 1.5 square units

The area of the whole rectangle is 3 units. Area is found by multiplying length by width. Only half of the rectangle is shaded, so if you take the whole area of the rectangle, and divide it in half, you get the area of that half rectangle.

By doing this, you divide 3 in half, and get 1.5 square units.

Hope this helps :)

Paul purchased a used vehicle that depreciates under a straight-line method.

Answer:

Option B. $900

Step-by-step explanation:

Let

y ----> the value of the car

x ----> the time in years

we know that

The linear function in slope intercept form is equal to

$y=mx+b$

where

m is the slope or the depreciation rate

b is the y-intercept or initial value of the car

we have

The y-intercept or initial value is equal to

$b=\$5,000$

$y=mx+5,000$

we have the ordered pair (5,500)

substitute the value of x and the value of y of the ordered pair in the linear equation and solve for m

$500=m(5)+5,000$

$5m=500-5,000\\5m=-4,500\\m=-\$900\ per\ year$

Is negative because is a decreasing function

The linear equation is equal to

$y=-900x+5,000$

therefore

It would depreciate $900 each year.

Colin received a bonus check for 2,500$. He is going to deposit the money into his bank account that receives 5.5% simple intere

This is the concept of financial mathematics, the simple interest rate is given by:
S.I.=(PRT)/100
where:
P=principle=$2500
R=rate=5.5%
T=time=1 year
Hence;
S.I.=(5.5*2500.1)/100
=$137.5
Thus the total amount he had after 1 year will be:
2500+137.5
=$2,637.5
