Answer:
4th option
Step-by-step explanation:
The given expression is:
In order to simplify this expression we have to multiply and divide it with the conjugate of the denominator i.e multiply and divide the entire expression with , as shown below:
Thus, 4th option gives the correct answer.
Step-by-step explanation:
a)
dy/dx = 4x √(1 − y²)
Separate the variables:
dy / √(1 − y²) = 4x dx
Integrate:
sin⁻¹ y = 2x² + C
Solve for y:
y = sin(2x² + C)
b)
Plug in initial value.
4 = sin(0 + C)
Sine cannot be greater than 1, so there is no solution.
Answer:
Angle CBA
Step-by-step explanation:
It would be CBA because Angle 1 is between those 3 points. Angle 1 is where B is so B would have to go in the middle.
Hope this helps :)
Answer:
(-2,-4)
Step-by-step explanation:
The given system is
Add both equations to eliminate y
Simplify both sides to get:
Divide both sides by 2
Put x=-2 into one of the equations say, x+y=-6 and solve for y
The solution is (-2,-4)
Line 1 to Line 2: Associative Property(?)
Line 2 to Line 3: Associative Property
The numbers in the parenthesis are switched, which is associative property.
