Answer: the first one .00000000058
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
We are looking for an exponential function
where r is less than 1.
a works because it is in the form
where r is less than 1.
b is in the form
but r is more than 1.
c. and d. are not even exponential functions.
c. is a polynomial
d. is a constant polynomial (no variable)
There are 180° in a triangle so you do
180- (30+30)
=180 - 60
=120
Therefore the answer is x = 120
