the function p(t)=3(e^0.0866t describes how to find the pollution level p(t) in relation to any time t, where t is the number of
ddd [48]

The pollution level in 1980 was 7.13 to the nearest hundredth ⇒ answer c

Step-by-step explanation:

The function p(t)=3(e^{0.0866t}) , 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

∵ p(t)=3(e^{0.0866t})

∵ t is the number of years after 1970

∴ t = 1980 - 1970 = 10 years

- Substitute the value of t in the equation above

∴ p(t)=3(e^{0.0866*10})

∴ p(t)=3(e^{0.866})

∴ p(t) = 7.13214 ≅ 7.13 to the nearest hundredth

The pollution level in 1980 was 7.13 to the nearest hundredth

Two roots of a third degree polynomial function f(x) are –4 and 4. Which statement describes the number and nature of all roots
marta [7]

Answer:

Step-by-step explanation:

A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.

If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
