Chepi is an ecologist who studies the change in the narwhal population of the arctic ocean over time. she

observed that the population loses 5.6% of its size every 2.8 months. the population of narwhals can be

modeled by a function, n, which depends on the amount of time, t (in months).

when chepi began the study, she observed that there were 89,000 narwhals in the arctic ocean.

write a function that models the population of the narwhals t months since the beginning of chepi's study.

Step-by-step explanation:

Given that Chepi is an ecologist who studies the change in the narwhal population of the Arctic ocean over time. She   observed that the population loses 5.6% of its size every 2.8 months. The population of narwhals can be

modeled by a function, N, which depends on the amount of time, t (in months).

Initial population = 89000

Since it loses 5.6% every 2.8 months we can write

where t is the no of months from the beginning

i.e. where t is the number of months.

Step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
