The answer and explanation in the pic below
Good luck,!
If helped..mark brainliest please ;)
Answer:
A.
B.Therefore the solution is defined on the interval:
6≤ x ≤ +∞
Step-by-step explanation:
Given differential equation is
Integrating both sides:
........(1)
Given y(0)= 6
it means y=0 when x=6
Putting x=6 and y=0 in the equation (1)
Equation (1) become:
Therefore
(B)
The quantity under root must greater than or equal to zero.
Therefore,
When x≥0 then the value of is real other wise the value of is imaginary.
Therefore the solution is defined on the interval:
6≤ x ≤ +∞
Answer:
<u>x = -2</u>
<u>y = -6</u>
Step-by-step explanation:
<u>Equating the equations</u> :
- x - 4 = 4x + 2
- 3x = -6
- x = -2
62/1 99.2/x
99.2/62 = x
The answer is 1.6 hours.
