Answer:
f(x) = 
Step-by-step explanation:
The given options are,
a) f(x) = 
b) f(x) = 
c) f(x) = 
d) f(x) = 
Now, clearly a) is a monotonically increasing function, hence discarded, and both of c) and d) don't pass through (0, 1) hence they are also discarded.
Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.
The answer is 30

Answer:

Step-by-step explanation:
We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:

Let's solve for x.
Combine like terms:

Add 15 to both sides:

Subtract 31 from both sides:

Divide both sides by 2:

So x is 82°.
Hope this helped!
The sum is 183/20
