Answer:

The points (-2, 0) and (3,5) are the ONLY solutions of the given sets of equations.

Step-by-step explanation:

Here, the given equations are: y + 4 = x^{2}  , y -x = 2

Now checking for the given points:

(a) (-2, 0)

Here, y + 4 = 0 + 4 = 4 =   (-2)^{2}  =  x^{2} \\y- x = 0 -(-2) = 2  = RHS

Hence,  (-2, 0) is the solution of the given equations.

b) Checking for (2,0), as (-2, 0) is a solution as shown above

Here, y + 4 = 0 + 4 = 4 =   (2)^{2}  =  x^{2} \\y- x = 0 +  (-2) = -2  \neq 2(RHS)

Hence,  (2, 0) is NOT the solution of the given equations.

c) Checking for (3,5), as (-2, 0) is a solution as shown above

Here, y + 4 = 5 + 4 = 9 =   (3)^{2}  =  x^{2} \\y- x = 5 -3 = 2 -  (RHS)

Hence,   (3,5), is the solution of the given equations.

Hence, the points (-2, 0) and (3,5) are the ONLY solutions of the given sets of equations.

Find csc0 and cos0 , where 0 is the angle shown in the figure. Give exact values, not decimal approximations.
solniwko [45]

Answer:

csc(θ) =  1.1662

cos(θ)  = 0.5145

Step-by-step explanation:

I attach the image of your question in the picture below

We know the values of the adjacent and opposite cathetus

tan(θ) = Opposite / Adjacent

tan(θ) = 5/3 = 1.666

θ = tan^-1 (5/3)

θ = 59.0362 °

Now that we have the angle, we can easily find the value of the expressions needed

csc(θ) = 1 / sin(θ)  = 1/ (0.85749) = 1.1662

cos(θ)  = 0.5145
