You deposit $800 in an account that pays 2.65% annual interest compounded continuously. What is the balance after 12 years? Use

balu736 [363]

Answer:Let P = initial investment

r = annual interest rate (decimal form)

t = number of years

A(t) = amount after t years

Then, A(t) = Pert

A(12.5) = 800e(0.0265)(12.5)

= 800e0.33125

= $1114.17

-6 - 3(2x + 4) = 18what’s the answer

Brrunno [24]

Answer:

$x=-6$

Step-by-step explanation:

$-6-3\left(2x+4\right)=18$

Add 6 to both sides:

$-6-3\left(2x+4\right)+6=18+6$

$-3\left(2x+4\right)=24$

Divide both sides by -3:

$\frac{-3\left(2x+4\right)}{-3}=\frac{24}{-3}$

$2x+4=-8$

Subtract 4 from both sides:

$2x+4-4=-8-4$

$2x=-12$

Divide both sides by 2:

$\frac{2x}{2}=\frac{-12}{2}$

$x=-6$

Help me please. This is my last question

Crazy boy [7]

Answer: D. 44

Step-by-step explanation:

Here, we need to know the concept of trigonometry.

Sine (sin) = Opposite/Hypotenuse = O/H
Cosine (cos) = Adjacent/Hypotenuse = A/H
Tangent (tan) = Oppostie/Adjacent = O/A

-----------------------------------------------------------------------------

Given

- The adjacent side of angle x and the hypotenuse.

- We are going to use Cosine.

<u>Solve</u>

cos (x) = 15/21

x = cos⁻¹ (15/21)

x ≈ 44

Hope this helps!! :)
