Answer:
it's the square and the rectangle
Use math induction proof method will be usefully
for n=1 will get
1^2 = 1(6*1^2 -3*1 -1)/2
1 = 1(6-4)/2
1 = 1(2)/2
1 = 1
suppose true for n=k and prove for k = k+1
hope this will help you
Answer:
shortest side = 15
Step-by-step explanation:
The question is a bit ambiguous. Do you mean (3/4) x or do you mean 3/(4x)?
I'll take it to be the first one.
(x + 3) + 4(x - 13) + (3/4)x = 3x + 6 Remove the brackets on the left
x + 3 + 4x - 52 + 0.75 x = 3x + 6 Combine
5.75x - 49 = 3x + 6 Subtract 3x from both sides.
2.75x - 49 = 6 Add 49 to both sides
2.75x = 55 Divide by 2.75
x = 55/ 2.75
x = 20
Now for the shortest side
x + 3 = 23
4(x - 13) = 4(20 - 13) = 4*7 = 28
(3/4)*20 = 15
The shortest side = 15
The cash price of the ring was $ 16,560.80.
Knowing the down payment, the interest rate and the monthly payments, to determine what is the cash price of the ring, the following calculation must be performed, applying the compound interest formula:
- Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest
- X x (1 + 0.072 / 12) ^ 3.5x12 = 360 x 42
- X x 1.006 ^ 42 = 15,120
- X x 1.2856 = 15,120
- X = 15,120 / 1.2856
- X = 11,760.80
- 11,760.80 + 4,800 = Cash price
- 16,560.80 = Cash price
Therefore, the cash price of the ring was $ 16,560.80.
