The answer is option 2: 4b = 7. The other options all equal 4.
Check the picture below.
now, keep in mind that ship B is going at 20kph, thus from noon to 4pm, is 4 hours, so it has travelled by then 20 * 4 or 80 kilometers, thus b = 80.
whilst the ship B is moving north, the distance "a" is not really changing, and thus is a constant, that matters because the derivative of a constant is 0.
The the value of f(n)=
Step-by-step explanation:
The Arithemetic sequence is given as a,a+d,a+2d......a(n-1)d
and f(n)=a(n-1)d
The given sequence is 1/3,4/3,7/3...
By comapring with Arithemetic sequence,
we get a=1/3
a+d=4/3
1/3 + d = 4/3
d=1
To find value of f(10):
take n=10
f(n)=
f(n)=
f(n)=
f(n)=
Answer:
3.25 years (nearest hundredth)
Step-by-step explanation:
<u>Compound Interest Formula</u>

where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- n = number of times interest applied per time period
- t = number of time periods elapsed
Given:
- A = $4916
- P = $4000
- r = 6.4% = 0.064
- n = 4 (quarterly)
Substitute the given values into the formula and solve for t:








Therefore, it will take 3.25 years (nearest hundredth) for the account to grow to $4916.

Answer:
Step-by-step explanation:
656 ≈660 and 106 ≈ 100
this means
660×100
=66000
⇒ 656×106 ≈ 66000
