Answer:
51°
Step-by-step explanation:
Given
<QPR = 39°
<PQR = 90° ( inscribed angle in semi circle)
Now
<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)
39° + 90° + <PRQ = 180°
<PRQ = 180° - 39° - 90°
<PRQ = 51°
Hope it will help :)
P(x) = 2x² - 4xq(x) = x - 3
To find the answer, we plug q(x) into p(x):
p(q(x)) = 2(x - 3)² - 4(x - 3)p(q(x)) = 2(x² - 6x + 9) - 4x + 12p(q(x)) = 2x² - 12x + 18 - 4x + 12p(q(x)) = 2x² - 16x + 30
The third option is correct.
Answer:
Yes repetition is permitting in permutations/combinations. It depends on the problem. For example a password being "555" is allowed. But in a race, racers logically can not repeat.

Answer:
12/19 or 0.6315
Step-by-step explanation:
You see that the denominator of 3/4 is 4 and the numerator of 16/19 is 16 both 4 and 16 are common factors, so you can reduce this to 3x4/19 then multiply 3/1 x 4/19 to give you 12/ 19 because 3x4 is 12 and 1x19 is 19.
