During a chemical reaction, the function y=f(t) models the amount of a substance present, in grams, at time t seconds. At the start of the reaction (t=0) , there are 10 grams of the substance present. The function y=f(t) satisfies the differential equation dydt=−0.02y^2

The solution of differential equation =

y =

Step-by-step explanation:

Given-

y=f(t) models the amount of a substance present, in grams, at time t seconds

when t = 0  then y = 10

the differential equation is

Integrate both side

+ C

when t = 0  then y = 10

C =

y =

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
