Using the PSN method:
P = -9
S = 8
So N = 9,-1
Using 9 and -1 in the original equation gives:
Step-by-step explanation:
Use SOH-CAH-TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Side a is adjacent to the 29° angle, and 14 is opposite of the 29° angle. So use tangent:
tan 29° = 14 / a
a = 14 / tan 29°
a ≈ 25.3
Side c is the hypotenuse, and 14 is opposite of the 29° angle. So use sine:
sin 29° = 14 / c
c = 14 / sin 29°
c ≈ 28.9
Answer:
The vertex of a parabola is found by
'h' position = -b / (2 * a) = 0 / 2 * -4 = 0
'y' position = ah^2 + bh + c = -4*0 + 0 -20
vertex = (0, -20)
Step-by-step explanation:
Answer: there is no sufficient evidence
Step-by-step explanation: We need to perform an hypothesis test on the average gram setting on the machine before we can draw out a conclusion.
We need the sample mean, either of population or sample standard deviation and sample size to perform the test.
None of these parameters was given to us, hence we don't have enough sufficient evidence to prove the statement.
