Answers

3/8 of the animals are birds
of the birds: 4/15 are birds of prey

If you want to know what fraction of the animalsat the zoo are birds of prey, you can calculate this using the following steps:

4/15 * 3/8 = 12 / (15*8) = 1 / (5*2) = 1 / 10 = 0.1

Result: In the town zoo, 1/10 of animals are birds of prey.

The temperature of a chemical reaction ranges between 30 degrees Celsius and 70 degrees Celsius. The temperature is at its lowest point when t = 0, and the reaction completes 1 cycle during a 10-hour period. What is a cosine function that models this reaction?

Answers

Let us consider function as T= Acos(teta)+B, max and min values will occur when cos(teta) = +1 and -1;
so 30= -A+B;
70= A+B;
solving both B=50, A=20;
also at t=0 , cos(teta)= -1 and finishes one cycle after t=10hour;
so(teta) = pi+pi*t/10;
so, T= 20cos(pi+pi*t/10) + 50;
