Answer:

$\boxed{\bold{B \ = \ 3,000 \ (1+0.42)^t}}$

Step By Step Explanation:

Goal: Write an equation that can be used to find her balance after 't' years

Deposit: $3,000

Interest: 4.2%

Turn 4.2% Into Decimal

Decimal: 0.42

't': 't' is undefined, so 't' stays the same

Balance = B

Balance = 3,000 Multiplied By 1 + 0.42. That is then multiplied by itself 't' times

10.) Find the exact value of cos⁡(2 sin^(−1)⁡(3/5) ). Do not use a calculator and show your work!

Talja [164]

Double angle identity for cosine:

$\cos\left(2\sin^{-1}\dfrac35\right)=\cos^2\left(\sin^{-1}\dfrac35\right)-\sin^2\left(\sin^{-1}\dfrac35\right)$

By the Pythagorean theorem, if $\sin x=\dfrac35$ , it follows that $\cos x=\dfrac45$ :

$\cos^2x+\sin^2x=1\implies \cos x=\pm\sqrt{1-\sin^2x}$

where we take the positive root because $-\dfrac\pi2\le\sin^{-1}x\le\dfrac\pi2$ , and $\cos x$ is non-negative throughout this domain.

So we have

$\cos^2\left(\sin^{-1}\dfrac35\right)-\sin^2\left(\sin^{-1}\dfrac35\right)=\left(\dfrac45\right)^2-\left(\dfrac35\right)^2=\dfrac7{25}$
