I believe it is supposed to be (0.8^x) because if it was like it was written, ur cake would be getting bigger.
ur range is gonna be P(t) while ur domain is t
P(t) = 350(0.8)^t
after 5 minutes
P(5) = 350(0.8^5)
P(5) = 350(114.688)
P(5) = 115 pieces <==
after 10 minutes
P(10) = 350(0.8^10)
P(10) = 37.581
P(10) = 38 pieces <==
after 15 minutes
P(15) = 350(0.8^15)
P(15) = 12.315
P(15) = 12 pieces <==
Step 1. Simplify the fraction
Step 2. Multiply the numerator
Step 3. Multiply denominator
There's your answer! hope this helps!
Answer:
-3.872983346
Step-by-step explanation:
In this case we have: cos θ = 1/4 Whose possible solutions are: θ = 2 * pi * n - Acos (1/4) θ = 2 * pi * n + Acos (1/4) Where, n belongs to the natural numbers. As sin θ <0 then the solution is: θ = 2 * pi * n - Acos (1/4) For n = 1 we get: θ = 4.965069236 radians Thus: tan θ = tan (4.965069236) = - 3.872983346 Answer: tan θ = -3.872983346
