Lynne invested 35,000 into an account earning 4% annual interest compounded quarterly she makes no other deposits into the accou
storchak [24]

Hello!

Lynne invested 35,000 into an account earning 4% annual interest compounded quarterly she makes no other deposits into the account and does not withdraw any money. What is the balance of Lynne's account in 5years

Data:

P = 35000

r = 4% = 0,04

n = 4

t = 5

P' = ?

I = ?  

We have the following compound interest formula

P' = P*(1+\dfrac{r}{n})^{nt}

P' = 35000*(1+\frac{0,04}{4})^{4*5}

P' = 35000*(1+0,01)^{20}

P' = 35000*(1,01)^{20}

P' = 35000*(1.22019003995...)

P' \approx 42,706.66

So the new principal P' after 5 years is approximately $42,706.66.  

Subtracting the original principal from this amount gives the amount of interest received:

P' - P = I

42,706.66 - 35000 = \boxed{\boxed{7,706.66}}\end{array}}\qquad\checkmark

Solve, finding all the solutions in [O, 2pi).<br> cot(x) cos(x) + cot(x) = 0
KATRIN_1 [288]

Step-by-step explanation:

cot(x) cos(x) + cot(x) = 0

cot(x) (cos(x) + 1) = 0

cot(x) = 0 or cos(x) = -1

cot(x) = 0

x = π/2, 3π/2

x ≠ 0, π

cos(x) = -1

x = π

Therefore, the answer is x = π/2, 3π/2.

I'm not sure what I got wrong for this question... anything may help
torisob [31]

Answer:

Wrong: Linear functions, cubic functions

Step-by-step explanation:

Both can decrease. Cubic functions nearly always decrease at some point and, if there is a negative slope, linear functions can decrease as well.

The y-intercept is where the curve crosses through the y axis (it intercepts it). In this case the y intercept would be worth three dollars at year 0. As years are time, and time is generally placed along the x axis.
