Answer:
The accumulated amount after 4 years is $1280.
Step-by-step explanation:
Principal = $1000
Time = 4 years
Rate of Interest = 7%
SIMPLE INTEREST =
⇒SI =
or, the amount of simple Interest = $280
Now, Accumulated Amount = Principal Amount + Simple Interest
= $1000 + $280
= $1280
Hence, the accumulated amount after 4 years is $1280.
Answer:
No, Peter is correct.
Step-by-step explanation:
Since 24 minutes = 0.4 hour, 7 hours, 24 minutes is equal to 7.4 hours, which is equivalent to what Peter had said, therefore, Peter is correct.
<u>Answer</u>
B. f(n) = 56(0.5)^n-1
<u>Explanation</u>
f(n) (1) 56
(2) 28
(3) 14
(4) 7
To find the correct relation we have to test all of them.
A. f(n) = 28(0.5)^n
f(1) = 28(0.5)¹
= 28 × 0.5 = 14
<em>f(n) = 28(0.5)^n ⇒ Not correct relation</em>
B. f(n) = 56(0.5)^n-1
f(1) = 56(0.5)¹⁻¹ = 56×1
= 56
F(2) = 56(0.5)²⁻¹ = 56 × 0.5 = 28
F(3) = 56(0.5)³⁻¹ = 56 × 0.25 = 14
<em> f(n) = 56(0.5)^n-1 ⇒ It is the correct relation</em>
C. f(n) = 56(0.5)^n
f(1) = 56(0.5)¹ = 56 × 0.5 = 28
<em>f(n) = 56(0.5)^n ⇒ Not correct relation</em>
D. f(n) = 112(0.5)^n-1
f(1) = 112(0.5)¹⁻¹ = 112 × 1 = 112
<em>f(n) = 112(0.5)^n-1 ⇒ Not correct relation</em>
The answer is d (i.e. 51).
the first 9 pages utilize 9 digits. the remaining 21 pages utilize two digits number. Therefore,
21*2=42
the total is 42+9=51
