Find the domain for the particular solution to the differential equation dy dx equals the quotient of 3 times y and x , with ini
Svetach [21]
For this case we have the following difference equation:
 dy / dx = 3xy&#10;
 Applying separable variables we have:
 dy / y = 3xdx&#10;
 Integrating both sides we have:
 \int\ ({1/y}) \, dy =  \int\ {3x} \, dx
 ln (y) = (3/2) x ^ 2 + C&#10;
 applying exponential to both sides:
 exp (ln (y)) = exp ((3/2) x ^ 2 + C)&#10;&#10; y = C * exp ((3/2) x ^ 2)
 For y (1) = 1 we have:
 C = 1 / (exp ((3/2) * 1 ^ 2))&#10;&#10;C = 0.2
 Thus, the particular solution is:
 y = 0.2 * exp ((3/2) x ^ 2)&#10;
 Whose domain is all real.
 Answer:
 y = 0.2 * exp ((3/2) x ^ 2)
 Domain: all real numbers

The percentage profit is 140%

What is percentage?

Percentage can be described as the expression of a number in hundredth.

The formula for calculating percentage profit is

profit/cost price × 100

cost price=  $50
selling price= $15
number of mats produced= 8

selling price of the mat= 15 × 8
= 120

Profit= selling price-cost price

= 120-50
$70

Therefore the percentage profit can be calculated as follows

= 70/50 × 100
= 1.4 ×100
= 140

Thus, the percentage profit is 140%

1.

Shirts cost $20 each and ties cost $12 each.

<u>Expression for the cost:</u>

  • 20s + 12t

Correct choice is B

2.

<u>An expression that represents 40% of a number is:</u>

  • 40*n/100 = 0.4n

Correct choice is B. False

3.

t = -2, x = 3 and z = 5

  • 4z + 3x − t =
  • 4*5 + 3*3 - (-2) =
  • 20 + 9 + 2 =
  • 31

Correct choice is C. 31
