Answer:
y=1/2x+1/2
Step-by-step explanation:
In order to find the slope, you can use rise/run, in this case, the slope is 1/2 and the y-intercept is at (0, 0.5)
Let , so that .
Recall that
so we get the antiderivative
and back-substitute to get it in terms of :
Answer:
R = 3.057% per year
Step-by-step explanation:
This is a compound interest question
From the question, we have the following information
P = Principal = $1,725.95.
A = Amount after 25 years = $3,703.05
T = Time = 25 years
n = Compounding frequency = compounded monthly = 12
r = interest rate = ???
The formula to calculate the interest rate in a compound interest question =
r = n[(A/P)^1/nt - 1]
r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]
r = 3.057%
Therefore, the interest rate on the account is 3.057%
If she has $4800 then 7.5% of that would be 360
4800(0.075)=360
so that's how much she can deduct
Answer:
The answer to your question is below
Step-by-step explanation:
convert tanx to sinx/cos x
simplify
sin²x + cos²x = 1 Use identity of sinx and cosx
sin²x = sin²x
