Answer:
after 4 months $8352.96
AFTER 13 MONTH $7426.507
AFTER 23 MONTH A = 7675.69
Step-by-step explanation:
Given data:
P = $9388.81
Compound interest cab be determined as
A = P( 1+ r/n)^(nt)
after 4 months
A = 9513.58
But he has to pay $1160.62 after 4 month so remaining amount is
P = 9513.58 - 1160.62 = $8352.96
AFTER 13 MONTH, so total time is 9 month
A = 8604.79
But he has to pay $1178.29 after 13 month so remaining amount is
P = 8604.79 - 1178.28 = $7426.507
AFTER 23 MONTH so total time is 10 month
A = 7675.69
ANSWER: 40
EXPLANATION:
1) 40.73 to 1 significant figure = 40.
2) 1.06 to 1 significant figure = 1.
3) Therefore, we just multiply 40 by 1, which equals 40.
FURTHER EXPLANATION (IF NEEDED):
With significant figures, whole numbers such as 10, 20, 50 etc. have 1 significant figure. This is because the 0 does not count as a significant figure.
With decimals, all numbers after the decimal point are also included as significant figures (even 0). E.g. 40.73 has 4 significant figures and 1.06 has 3 significant figures.
EXAMPLES (IF NEEDED):
Rounding to 2 significant figures:
Rounding to 3 significant figures:
- 40.73 = 40.7
- 1.06 = 1.06 (because it's already in 3 significant figures)
Rounding to 4 significant figures:
- 40.73 = 40.73 (already in 4 significant figures)
- 1.06 = 1.060 (0 is counted as a significant figure if there is a decimal or another number comes after that 0)
E.g. 1006 has 4 sig figs, while 1060 would have 3 sig figs because the last 0 is not counted as a significant figure. 10.60 would have 4 sig figs because of the decimal.
Hello!
Since x = 19 the answer to the problem is 19
Hope this helps!
Answer:
Step-by-step explanation:
we know that
The equation of a exponential decay function is given by
where
y is the value of the investment
x is the number of years
a is the initial value
r is the rate of change
we have
