If the sequence f is defined as
then
As you can see above, the difference between two consecutive terms gives us a constant.
So f is actually an arithmetic progression (AP), and it has (– 8) as its common difference:
• If f(1) = 100, then

Dup= 72 miles
<span>ddown= 120 miles </span>
<span>v= riverspeed </span>

<span>rdown= 32mph + v </span>
<span>t both ways= t </span>
<span>d=r*t </span>
<span>d/r=t </span>
<span>t=ddown/rdown </span>

3b+b because 3+1=4 just add b and replace 1 with b
b is the same as 1
3b is the same as 3
If the present value and number of periods are the same, but interest rate is lowered, this means that less interest needs to be paid each month, and the correct answer is a) decrease the monthly payment.
Monthly payments would increase if the interest rate increases. Monthly payments cannot be eliminated.
Answer:
Step-by-step explanation:
<u>TRUE</u>
All isosceles triangles have at least 2 acute angles due to 2 sides are equal.
The exterior angle of an equilateral triangle is obtuse.
If the perimeter of an equilateral triangle is P, then the length of each of the sides is P/3.
<u>FALSE</u>
All isosceles triangles are equilateral triangles.
If you know the length of one of the legs of an isosceles triangle, you can determine it’s the perimeter
