Answer:
x y Negativo tres cuartos Negativo
Step-by-step explanation:
Answer: The equation that can be used to find x, is given by

Step-by-step explanation:
Let the number of degrees he lowered the temperature by each time be 'x'.
Temperature he starts with = 12.2° C
Temperature he stopped with = -14.61° C
According to question, it is said that he lowers the temperature 5 times by the same amount each time.
So, it becomes,

Hence, the equation that can be used to find x, is given by

Answer:
No correlation
Step-by-step explanation:
There is not a positive line of dots
There is not a negative line of dots
so that means there is no correlation
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.
Can you add the picture with it cuz i think you forgot
