Answer:
h(x) = - 4x² + 5
Step-by-step explanation:
To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)
h(x) = - 2(2x² + 1) + 7
= - 4x² - 2 + 7
= - 4x² + 5
Answer: 3 + 7i
Step-by-step explanation:
Equation expanded: 12 + 5i - 9 + 2i // now simplfy
12 - 9 = 3
5i + 2i = 7i
// together, we get
3 + 7i

Answer:
26,664 inches
Step-by-step explanation:
Set up a proportion to solve this...
33 inches is to 1.25 miles as 'x' inches is to 1,010 miles
33/1.25 = x/1,010 now solve for x by cross multiplying
33,330 = 1.25x
33,330/1.25 = x
26,664 = x
m∠H = 50°
∠H is a inscribed angle, and so that the intercepted arc would be twice the amount of the angle.
Arc KI = 100°
Because ∠KGI & ∠HKI share the same arc, the measurement for ∠KGI will be the same as ∠HKI, or 50°
m∠KGI = 50°
Next, find m∠KJI. arcKJI = 2(∠H) = 2(50) = 100
m∠KJI = 100°
