Use the trigonometric function.

\sin30^o=\dfrac{x}{20}\\\\\sin30^o=\dfrac{1}{2}\\\\\dfrac{x}{20}=\dfrac{1}{2}\ \ \ |\cdot20\\\\x=10

\sin60^o=\dfrac{y}{20}\\\\\sin60^o=\dfrac{\sqrt3}{2}\\\\\dfrac{y}{20}=\dfrac{\sqrt3}{2}\ \ \ \ |\cdot20\\\\y=10\sqrt3

!Will mark BRAINILEST! What's the type of function that represents this pattern??

Exponentially growth.

Let’s say one person starts with the flu. After the first day, there are suddenly

1 x 2 = 4 people sick

And the rest of the days just explode in magnitude:

Day 2: 1 x 2 x 2 = 8 people sick
Day 3: 1 x 2 x 2 x 2 = 16 people sick
Day 4: 1 x 2 x 2 x 2 x 2 = 32 people sick
Etc.

You can rewrite all that repeated multiplication as *exponents*, which is why we call it exponential growth.

Day 1: 1 x 2^1 = 4
Day 2: 1 x 2^2 = 8
Day 3: 1 x 2^3 = 16

And after n days, 1 x 2^n - or just 2^n - people would be sick.

50 points will mark brainiest match each exponential function to it's rate of change
nordsb [41]

Step-by-step explanation:

An exponential function of a^x (a>0) is always ln(a)*a^x, as a^x can be rewritten in e^(ln(a)*x). ... The derivative shows, that the rate of change is similiar to the function itself. For 0<a<1, ln(a) becomes negative and so is the rate of change.
