Answer:  The required value of the expression at x = 0 is 7.

Step-by-step explanation:  We are given to evaluate the following expression for x = 0.

g(x)=7+(-4x^2)~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To evaluate, we must substitute x = 0 in the given expression.

So, putting x = 0 in equation (i), we get

g(x)\\\\=7+(-4x^2)\\\\=7-4x^2\\\\=7-4\times 0^2\\\\=7-0\\\\=7.

Thus, the required value of the expression at x = 0 is 7.

mariarad [96]

Answer:

∅ = 42°

Step-by-step explanation:

90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)

because the radii lines form an isosceles triangle, ∠∅ also = 42°
