Answer:
(x + 10 and (x + 12)
Step-by-step explanation:
x^2 + 22x + 120 = ( ? )( ? )
We need to find two constants whose product is 120 and whose sum is 22.
Let the two constants be a and b. Then:
a*b = 120 and a + b = 22.
It's a bit easier to find a and b such that a + b = 22: 2 and 20, 4 and 18, 6 and 16, and so on. Note that 6 + 16 = 22 (correct) but that 6*16 = 96 (not correct). Try 8 and 14, 10 and 12. Note that 10 + 12 = 22 and that 10*12 = 120. So the desired roots are {10, 12} and the desired factors are (x + 10 and (x + 12).
Check: Does (x + 10)(x + 12) work out to x^2 + 22x + 120?
x^2 + 12x + 10x + 120 = x^2 + 22x + 120? YES
The factors are (x + 10 and (x + 12).
Try this option.
1 is for scalar (result is number), 2 is for vector (result is vector).
Answer:
about 60
Step-by-step explanation:
the ratio of vowels to consonants is 2:6
that can be simplified to 1:3
that means the vowels would be spun on about one third of the time
Answer:
b
Step-by-step explanation:
b should be the answer
The angular velocity by definition is given by:
w = rev / t
Where:
rev: revolutions
t: time
Substituting values we have:
w = (6 * (2 * pi)) / (12)
w = 3.141592654 rad / s
Answer:
the average angular velocity of the spinner, in radians per second, for the 12-second interval is:
w = 3.141592654 rad / s
