Important variables to know:
I = interest
P = principal (investment)
R = simple interest rate
T = years
Formula: I = PRT
What information do we have?
I = $960
P = $4000
T = 3 years
R = ?
Plug into formula:
960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08
A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)
Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.
Step-by-step explanation:
There is a rule that if c^2 > a^2 + b^2, then it is an obtuse triangle.
*c is the longest side
I attached more information on it below.
Answer:
y=4x-1
Step-by-step explanation:
the lines can be written in their slope intercept form which is y=mx+b
m= slope=4
b=the intercept point=-1
so we have:
y=4x-1

Answer:</h2>
Percentage is related to 100 and tells us how much we have of a quantity compared to another one. Suppose you have 100 cars and want to know how much cars are in red color. If 70 cars are red, then 70 percent of the cars are red. In general, we can find the percentage of a number following the steps:
For this example, let's take number 200 and the percentage 20%:
STEP 1: Multiply the number by the percentage:
200 x 20 = 4000
STEP 2: Now divide the number by 100:
400/100 = 40
STEP 3: If necessary., round to the desired precision.
The slope is 2
the y-intercept is at (0, 7)
