The least common denominator of 5/12 and -9/16
The answer is 48.
Now, we have to change the numerators also to make this a equal fraction to the first ones we had.
5*4 = 20
12*4 = 48
20/48
-9*3 = -27
16*3 = 48
-27/48
Answer:
y = - 
x²
Step-by-step explanation:
Since the vertex is at the origin and the focus at (0, - 4) then the parabola opens vertically down with equation
x² = 4py ( p is the distance from the vertex to the focus )
Here p = - 4 ( focus is below the vertex ), thus
x² = 4(- 4)y = - 16y ( divide both sides by - 16 )
y = - x²
The answer is it is a statistic because the value describes a characteristic of a sample.
For this case we have the following scale factor:
k = 3/14
Therefore, for the relationship of areas we have:
A1 / A2 = k ^ 2 = (3/14) ^ 2
A1 / A2 = 9/196
For the relation of volumes we have:
V1 / V2 = k ^ 3 = (3/14) ^ 3
V1 / V2 = 27/2744
Answer:
The ratio of their corresponding areas is:
9: 196
The ratio of their corresponding volumes is:
27: 2744
