If cot^(4)x − cot^(2)x = 1, then the value of cos^(4)x + cos^(2)x is

1

Step-by-step explanation:

------- (1)

Putting the value of in the equation:

           (Using the identity

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
