Let y(t) be the percentage of the population that supports a particular government policy. The rate of change of the level of support for the policy is proportional to both the percentage of the population that agrees with the policy and the percentage that disagrees with the policy. Let the constant of proportionality for this relationship be written as k. dy/dt = ky(100-y)
Enter the differential equation that is satisfied by y.
Suppose that k is negative, people also change from agreeing to disagreeing because they have second thoughts about the policy. Suppose that this rate is proportional to the percentage of people that agree with the policy, with constant of proportionality equal to c.

true

explanation:

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
