Answer:
3.2%
Step-by-step explanation:
-Let r be the simple interest rate per annum.
-Given the total amount after 1 year is 1857.60, the initial amount is 1800
#We use the simple interest formula to find the rate of interest:
Hence, the annual interest rate on the deposit is 3.2%
(2x+7)-(3x-5) you first distribute the negative sign to the 3x-5, making the expression 2x+7-3x+5, which simplifies to -x+12
The answer is 2(3tan(x)-tan^3(x))/(1-3tan^2(x)) but it is a very long and tedious calculation using alot of trig identities.
Answer:
−6(+2)
Step-by-step explanation:
Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
<u>aₙ = 3 + 4ⁿ⁻¹</u>
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
<u>Let's check if the answer is right:</u>
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct
Hope this helps!
