Answer:

A'(t) = rA(t)

Step-by-step explanation:

Given

A(t) \to Amount

Required

The differential equation

The equation for the amount is:

A(t) = A_0 * e^{rt}

Where:

A_0 \to initial amount

r \to rate

t \to time

DifferentiateA(t) = A_0 * e^{rt}

A'(t) = A_0 * r * e^{rt}

So, we have:

A'(t) = rA_0 * e^{rt}

From the question, we have: A(t) = A_0 * e^{rt}

So, the equation becomes

A'(t) = rA(t)

Anna007 [38]

Answer:

a) 83%

b) 0.892

Step-by-step explanation:

percentage that attends class on friday = 74%

percentage that pass because they attend class on friday = 88%

percentage that pass but did not go to school on friday = 20%

a) percentage of students expected to pass the course

  = (74% x 88%) +(88% x 20%)

   = 0.6512 + 0.176

   = 0.8272

   = 83%

b) If a person passes the course, what is the probability that he/she attended classes on Fridays

        = 74% divided by 83%

        = 0.892

Three consecutive integers whose sum is -147
suter [353]

Step-by-step explanation:

Let the first integer be x

2nd integer = x + 1

3rd integer = x + 2

x + x + 1 + x + 2 = -147

3x + 3 = -147

3x = -147 - 3

3x = -150

x = -150 ÷ 3

x = -50

The three consecutive integers are

-50, -49, -48
