The solution of a certain differential equation is of the form y(t)=aexp(7t)+bexp(11t), where a and b are constants. The solutio
Solnce55 [7]

Answer:

Step-by-step explanation:

Given that the solution of a certain differential equation is of the form

y(t) = ae^{7t} +be^{11t}

Use the initial conditions

i) y(0) =1

1=a(1)+b(1)\\a+b=1 ... I

ii) y'(0) = 4

Find derivative of y first and then substitute

y'(t) = 7ae^{7t} +11be^{11t}\\y'(0) =7a+11b \\7a+11b =4 ...II

Now using I and II we solve for a and b

Substitute b = 1-a in II

7a+11(1-a) = 4\\-4a+11 =4\\-4a =-7\\a = 1.75 \\b = -0.75

Hence solution is

y(t) = 1.75e^{7t} -0.75e^{11t}

seven out of every 8 students surveyed owns a bike. The difference between the number of students who own a bike and those who d
guajiro [1.7K]
So if x people were surveyed, \frac{7}{8} people owned a bike and \frac{1}{8}  did not.

The difference between them is 72:
\frac{7}{8} x-\frac{1}{8} [/tex] =72
so this means that
\frac{6}{8} x=72

let's simplify:

\frac{3}{4} x=72

and divide by 3:

\frac{1}{4} x=24

and mupliply by 4:

x=96

so 96 people were surveyed

<span>3x + y =3 
Y = 2x - 7

substitute </span>Y = 2x - 7 into  3x + y =3 
3x + y =3 
3x +2x - 7 =3 
5x = 10
x = 2

Y = 2x - 7 = 2(2) - 7 = -3
