12.6$Answer:
Step-by-step explanation:
1$ - 20$ = 19$ / 3 = 6.3$
6.3$ x 2 = 12.6$
First, simplify the denominator into 1+3i. Then multiply both the numerator and denominator by 1-3i to rationalize the denominator. Then, the numerator becomes i+3, and the denominator becomes 10. So, the first answer is correct.
Answer:
53.5 and 36.5
The Sum of two angles is 90 degree
Is called complementary angle
53.5 + 36.5 =90
53.5 - 36.5 =17

Find constant a.
----------------------------------------------------------------------------
Given that g(4) = 8
--------------------------------------
Substitute x = 4
--------------------------------------
g(4) = a(4)² + 24 = 8
16a + 24 = 8
--------------------------------------
Take away 24 from both sides
--------------------------------------
16a = 8 - 24
16a = -16
--------------------------------------
Divide by 16 on both sides
--------------------------------------
a = -1
Now that we know that a = -1, plug it back to the equation.
g(x) = -x² + 24
--------------------------------------
Find g(-4)
--------------------------------------
g(-4) = - (-4)² + 24
g(-4) = -16 + 24
g(-4) = 8
----------------------------------------------------------------------------
Answer: 8
