Answer:
f(t) = 1.22·(173/122)^(t/5)
Step-by-step explanation:
(a) An exponential growth (or decay) function can be written using the form ...
f(t) = (initial value)·(ratio in period)^(t/period)
Here, we're given an initial value of 1.22, a growth ratio of 1.73/1.22 in a period of 5 years, so we can write the function as ...
f(t) = 1.22·(173/122)^(t/5)
__
(b) In 2038-2012 = 26 years, the value of the function is ...
f(26) = 1.22·(173/122)^(26/5) ≈ 7.50 . . . . million
Answer:
so what's 10 x 15?
that's what it's mainly asking you
10 x 15
answer: is 150
- that's what I think it is..
Answer:
f(-3) = -3
Step-by-step explanation:
Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.
Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>
Step 3: Use BEDMAS rules to complete the calculation.
Therefore the answer is f(-3) = -3.
Answer: 1
Step-by-step explanation: the cosine function oscillates between the values -1 to 1
The amplitude of this particular function is understood to be 1
A₁ = 1 = 4⁰
a₂ = 4 =4¹
a₃ =4 x 4=4²
a₄ =4 x 4² =4³
