Answer:

Step-by-step explanation:
We have been given two expressions
and

Now we need to find out least common multiple of these two expressions.
First we need to find out what is common factor of both expressions.
and

Least common multiple means find the expression which can be divided by both expressions.
15 and 6 both goes into 30
so 30 is part of LCM (least common multiple )
Now pickup the highest exponent of each variable.
So we get 
Hence required least common multiple is

Answer:
GI = 18; GE = 12; IE = 6
Step-by-step explanation:
The key to the question is to realize or find out what a centroid is and what it does. You can solve this question by knowing three things.
- The centroid is the meeting point of the three medians ( a median is a line that connects the midpoint of the side opposite a given vertex).
- The centroid divides the median in a ratio of 2:1. The longest segment is from the vertex to the centroid.
- The shortest segment is from the centroid to the midpoint of the side opposite the given vertex.
Point two is what you have to focus on.
GE/EI = 2/1
GE = 12 Given
Solution
GE / EI = 2/1 Substitute for the given
12 / EI = 2/1 Cross multiply
2*EI = 12 * 1 Simplify the right
2 * EI = 12 Divide by 2
EI = 12/2 Divide
Part Two
GI = EI + GE
GI = 6 + 12
GI = 18
EI = 6
Answer:

Step-by-step explanation:
Where p is the distance from focus to vertex, the equation of the parabola with focus at (0, p) is ...

Your parabola has p=9, so the equation is ...

Answer:
W = (1/7) t
Step-by-step explanation:
At t = 0, W = 0
At t = 56 minutes , W = 8 inches
W = k*t The y intercept = 0 because t = 0 W = 0
8 inches = k * 56 minutes
k = 8 / 56
k = 1/7 inches / minute
W = (1/7) t
