M = 3rt^2 - 2rv
2rv = 3rt^2 - M
v = (3rt^2 - M)/2r
Her studies
indicate that there is an inverse relationship between TV time and GPA, and
that a student who watched 15 hours of TV per week can be expected to have a
GPA of 3.5
In equation form
15 = k(1/3.5)
Solve for k
K = 15 * 3.5
<span>K = 52.5 is the constant
of variation</span>
Answer:
C
Step-by-step explanation:
Lucky guess I guess.
Average speed = (distance final - distance initial)/(time final - time initial)
Average speed = (30-0)km /(100 -0)min = 3/10 km/min
3/10 km/min *60 min/1 h = 180/10 km/h= 18 km/h
The correct answer is option B
(5 + 3i)(4+ 2i)
= 5(4+2i) + 3i(4+2i)
= 20 +10i + 12i +6i²
= 20 +22i +6(-1)
= 20 + 22i - 6
= 14 + 22i
