Anyone know how to do this??
Ghella [55]

Answer:

csc²(x)

Step-by-step explanation:

csc(x) = 1/sin(x)

sin²(x) + cos²(x) = 1

=> cos²(x) = 1 - sin²(x)

cos(2x) = cos²(x) - sin²(x) = (1 - sin²(x)) - sin²(x) =

= 1 - 2×sin²(x)

=> 2×sin²(x) = 1 - cos(2x)

sin²(x) = 1/2×(1-cos(2x))

=> 1 - cos(2x) = 2×(1/2×(1-cos(2x)) = 2×sin²(x)

=> 2 / (1-cos(2x)) = 2 / (2×sin²(x)) = 1/sin²(x) =

= 1/sin(x) × 1/sin(x) = csc(x)×csc(x) = csc²(x)

Solve equation by completing the square round to the nearest hundredth if necessary <br> X2-4x-=5
kipiarov [429]

Answer:

x=-1 and x=5

Step-by-step explanation:

we have

x^{2} -4x=5

Solve it by completing the square method

We take the coefficient of x that is -4, divide it by 2 and then square it

so

-\frac{4}{2}=-2

square it

(-2)^2 = 4

Adds 4 both sides

x^{2} -4x+4=5+4

Combine like terms right side

x^{2} -4x+4=9

Rewrite as perfect squares

(x-2)^{2}=9

take square root both sides

x-2=\pm3

x=2\pm3

therefore

x=2+3=5

x=2-3=-1
