Answer:

  • 10 chores
  • Sam

Step-by-step explanation:

A) If the playing times are to be the same, then the two expressions for playing time will be equal to each other.

  Ron = Sam

  3 +1.25c = 8 +0.75c

  0.50c +3 = 8 . . . . . . . . . . subtract 0.75c from both sides

  0.50c = 5 . . . . . . . . . . . subtract 3 from both sides

  c = 5/0.50 = 10 . . . . . divide by the coefficient of c

Each would have to complete 10 chores for their playing times to be the same.

__

B) When c = 4, we have ...

  Ron: 3 +1.25·4 = 3 +5 = 8

  Sam: 8 +0.75·4 = 8 +3 = 11

Sam spent the most gaming time if both completed 4 chores.

What divisor is represented by the synthetic division below?  –5 5 x + 5 x – 5
Tju [1.3M]
For this case, the dividend is given by:
 2x ^ 3 + 10x ^ 2 + x + 5

 We note that the following numbers:
 2, 10, 1, 5
 They are the coefficients of the polynomial and they are in the upper part of the division.
 The number -5 is the opposite value of the divisor constant.
 Therefore, the divisor is given by:
 x + 5
 Answer:
 
The divisor is:
 
x + 5

Find the solution of the differential equation dy/dt = ky, k a constant, that satisfies the given conditions. y(0) = 50, y(5) =
irga5000 [103]

Answer:  The required solution is y=50e^{0.1386t}.

Step-by-step explanation:

We are given to solve the following differential equation :

\dfrac{dy}{dt}=ky~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

where k is a constant and the equation satisfies the conditions y(0) = 50, y(5) = 100.

From equation (i), we have

\dfrac{dy}{y}=kdt.

Integrating both sides, we get

\int\dfrac{dy}{y}=\int kdt\\\\\Rightarrow \log y=kt+c~~~~~~[\textup{c is a constant of integration}]\\\\\Rightarrow y=e^{kt+c}\\\\\Rightarrow y=ae^{kt}~~~~[\textup{where }a=e^c\textup{ is another constant}]

Also, the conditions are

y(0)=50\\\\\Rightarrow ae^0=50\\\\\Rightarrow a=50

and

y(5)=100\\\\\Rightarrow 50e^{5k}=100\\\\\Rightarrow e^{5k}=2\\\\\Rightarrow 5k=\log_e2\\\\\Rightarrow 5k=0.6931\\\\\Rightarrow k=0.1386.

Thus, the required solution is y=50e^{0.1386t}.
