Answer:
g(f(x))=x^2 + 14x + 48
Step-by-step explanation:
you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.

Detailed solution is given below in the attached image
Answer:

Step-by-step explanation:
The measure of arc which the right triange cuts from the circle is
this means the central angle has the same measure.
Angle with measure
is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence

Angles with measures
and
are complementary angles (add up to 90°), so

Answer: 2.2x * 10^3
You would have to move the decimal place 3 times for 2.2x to get 2,200x, thus you get 10^3.
Hope this helps!
