Find the value of the trigonometric ratio. Simplify the ratio if possible.

sweet [91]

Step-by-step explanation:

Given that,

BC = 8

Ac = 15

We can find AB using the pythagoas theorem.

$AB=\sqrt{AC^2+BC^2}\\\\=\sqrt{15^2+8^2}\\\\AB=17$

We know that,

$\cos\theta=\dfrac{B}{H}$ , B is base and H is Hypotenuse

$\cosB=\dfrac{8}{17}$

Hence, this is the required solution.

you deposit 300 in an account that pays 5 1/2% annual interest compounded cnyinuously find the balance at the end of 5 years

algol [13]

First find the multiplier: 5.5% + 1 = 1.0505.

Then we do amount x (multiplier) to the power of how many years.

300 x (1.0505)^5

The answer is <span>383.79696707.

We round this to 2dp, making it £393.80

REMEMBER UNITS!!!

Hope this helps xox :)</span>
