F(1) = 45
f(n) = f(n-1) * 4/5
Step-by-step explanation:
f(n) = 45 x (4/5)ⁿ⁻¹
f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45
f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²
f(n) = f(n-1) * (4/5)¹ = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹

</span>What is 8 increased to 22.
I believe you want me to show you what is the interest increased from 8 to 22
Let’s start the solution process:
=> 8 is the original number and supposed to be the 100% value
=> 22 is the increased number
subtract 22 by 8 to know how much is added.
=> 22 – 8 = 14
=> 14 / 8 = 1.75
=> 1.75 * 100% = 175%
Thus, the added increased is around 175% of the original money</span>
3/7 or 3:7 because you tossed the dice 7 times and got an even number 3 of those times.
Answer:
0
Step-by-step explanation:
The negative would just cancel the positives out. Therefore, since they are both adding together the same things the negatives would make the outcome 0.
L= length= 2w+4
w= width
P= perimeter= 7w-3
SOLVE FOR WIDTH
Perimeter of a Rectangle Formula
P= 2(l + w)
7w - 3= 2((2w + 4) + w)
combine like terms in parentheses
7w - 3= 2(3w + 4)
multiply 2 by parentheses
7w - 3= (2*3w) + (2*4)
multiply in parentheses
7w - 3= 6w + 8
add 3 to both sides
7w= 6w + 11
subtract 6w from both sides
w= 11 width
LENGTH
l= 2w + 4= 2(11) + 4= 22 + 4= 26
PERIMETER
P= 7w-3= 7(11) - 3= 77 - 3= 74
CHECK
74= 2(26 + 11)
74= 2(37)
74= 74
ANSWER: The length is 26, the width is 11 and the perimeter is 74.
Hope this helps! :)
