Answer:
8x - 10
Step-by-step explanation:
Combine like terms:
2x + 6x - 10
= 8x -10
Evaluate the trigonometric expression using sum and difference formulas.
1. Observe that the f(t) is change by 4 per time t => there's a acceleration of 4 => f''(t) = 4; Take the derivative of it we can get a velocity function. f'(t) = 4t + c. Since the velocity from 100 to 80 is -20 (average), this means at t = 0, f'(0) = -22 => f'(t) = 4t - 22; Take the derivative again to get the position function: f(t) = 2t^2 - 22t + d, here d = 100 should be trivial. So, the function that models the relationship is f(t) = 2t^2 - 22t + 100.
2. By the compound interest formula:
A = P (1 + r/n)^(nt) , since it's yearly, so n = 1;
results A(t) = 100 (1+0.12)^t.
3. The average rate of change is basically finding the slope, m = y1 - y2 / x1 - x2.
Answer:
8
Step-by-step explanation:
because 40 devided by 5 equals 8 so thats how many hours in the afternoon
Answer: The answer is 20 pi over 5
Step-by-step explanation:
You start by finding the circumference which you would get 20 pi by doing 2 times pi times your radius which is 10 then you find the fraction of the circle using the central angle which is 1/5 then you multiply 1/5 by 20 pi which you would put over 1 which then gives you 20 pi over 5
