Answer:
Answer is B
Step-by-step explanation:
This is because you can combine both the green tiles. With the other options, you can't combine them.
(also I did the test )
For this case the first thing we must know is the following conversion of units:
1 AU = 1.50 * 10 ^ 8 Km
Applying the conversion of units we have:
(2,767) * (1.50 * 10 ^ 8) = 415050000
Rewriting we have:
4.15 * 10 ^ 8 Km
Answer:
A: 4.15 x 10 ^ 8 km
Answer:
a) see the attached file
b) Coordinates of vertex = (0, 4)
Step-by-step explanation:
Given:
Focus of parabola is and the directrix is
To sketch: the parabola
To find: coordinates of the vertex
Solution:
As the focus lies on the y-axis and y-coordinate of the focus is positive,
equation of parabola is
Here, denotes the vertex of parabola, focus is and the directrix is
According to question,
So,
On adding these equations,
Put in
So, equation of parabola is
For part a), see the attached file.
b)
Coordinates of vertex =
Answer:
3 v (v - 7) (w - 1) thus the answer is B:
Step-by-step explanation:
Factor the following:
3 v^2 w - 21 v w - 3 v^2 + 21 v
Factor 3 v out of 3 v^2 w - 21 v w - 3 v^2 + 21 v:
3 v (v w - 7 w - v + 7)
Factor terms by grouping. v w - 7 w - v + 7 = (v w - 7 w) + (7 - v) = w (v - 7) - (v - 7):
3 v w (v - 7) - (v - 7)
Factor v - 7 from w (v - 7) - (v - 7):
Answer: 3 v (v - 7) (w - 1)
Answer:
3.25 and 4
Step-by-step explanation:
2y + 1/2 > 2y - (5/4y - 9/2)
2y + 1/2 > 3/4y + 9/2
1 1/4y > 8/2
y > 3.2
of the choices, only 3.25 and 4 are greater than 3.2
(3.2 is not greater than 3.2)
