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

So based on the given options above, the correct answer would be option E. The explicit formula for the following geometric sequence which is 0.2, -0.06, 0.018, -0.0054, 0.00162, ... would be this: an = 0.2(-0.3)^n-1. When we say geometric sequence, this is the sequence of numbers wherein each term after the first is <span>found by multiplying the previous one by a fixed, non-zero number called the common ratio. Hope this answer helps.</span>
Answer:
Equation is x^2-100=0
Step-by-step explanation:
I'm assuming everything is in standard form. Just plug in the values.
1(x)^2+(0)x+(-100)=0
0 times x is 0, so it simplifies to
x^2-100=0
