Answer:
<h2><u><em>
x = 10</em></u></h2>
Step-by-step explanation:
The length of the base of an isosceles triangle is x. The length of the leg is 2x-2. The Perimeter of the triangle is 46. Find X.
2x - 2 + 2x - 2 + x = 46
5x - 2 - 2 = 46
5x = 50
x = 50 : 5
x = 10
Answer: Choice A
y=0.0714x-9.2682
==============================================
Explanation:
I used GeoGebra (free graphing software) to find the line of best fit, aka the regression line. You can do so by hand, but I think it's tedious busywork and prefer to use technology whenever possible. Other graphing and spreadsheet programs are able to compute the regression line as well.
Check out the diagram below.
Answer: $4,467.2
Step-by-step explanation:
The formula for this is A = P (1 - r) ^t
Where p is the Principal, r is the rate and t= time
Given from the question, p = $8000
rate= 11% = 11/100 = 0.11
Time = 5 years
Slot the values into the formula:
A= 8000 (1 - 0.11) ^5
= 8000 (0.89)^5
8000 × 0.5584
=$4,467.2
After 5 years, the worth of the car would have depreciated to $4,467.2
I hope this helps.
