The pollution level in 1980 was 7.13 to the nearest hundredth ⇒ answer c
Step-by-step explanation:
The function , where
- p(t) is the population level at any time t
- t is the number of years after 1970
We need to find the pollution level in 1980
∵
∵ t is the number of years after 1970
∴ t = 1980 - 1970 = 10 years
- Substitute the value of t in the equation above
∴
∴
∴ p(t) = 7.13214 ≅ 7.13 to the nearest hundredth
The pollution level in 1980 was 7.13 to the nearest hundredth

im pretty sure what u have ther is right
Answer:
Step-by-step explanation:
The function repeats the same shape after every units.
The function is symmetric with respect to the origin so it is a sine function.
The amplitude is 3 because the graph has range
The equation is of the form where a=3 is the amplitude.
Hence the required equation is
Answer:
a = -4
b = 5
c = -2
