You’ll need to make an exponential function in order to find your answer.
Let’s try the function f(x) = 870(1.037)^x.
Then, plug in three for x and your output will be the answer. Remember, you’re being asked for the balance, NOT the yield.
The answer is $970.19

The half-life of radioactive actinium (^227 Ac) is 22 years. How much will remain after 15 years? Find R first.
Llana [10]
Use the formula below.

Let A_0 = 1 because you just want to know the percentage left. Usually that's the initial amount.

t = 15, the number of years past. n = 22, the half-life.

A=A_0(0.5)^{\frac{t}{n}} \\  \\ A=0.5^{\frac{15}{22}} \\  \\ A=0.62 = 62\%

ABCD is a parallelogram. AB>AD. Prove: m∠ADB>m∠BDC. Show your work (statement reason maybe?)
Gwar [14]

In the parallelogram ABCD, join BD.

Consider the triangle Δ ABD.

It is given that AB > AD.

Since, in a triangle, angle opposite to longer side is larger, we have,

∠ ADB > ∠ ABD. --- (1)

Also, AB || DC and BD is a transversal.

Therefore,

∠ ABD = ∠ BDC

Substitute in (1), we get,

∠ ADB > ∠ BDC.
