Answer:
100 has <u>5</u> factor pairs, so that many different rectangles can be drawn. 15 only has <u>2</u> factor pairs, so only that many different rectangles can be drawn.
Explanation:
there are 5 pairs of whole numbers that multiplied together will be 100:
- 100 x 1 = 100
- 50 x 2 = 100
- 25 x 4 = 100
- 20 x 5 = 100
- 10 x 10 = 100
while there are only 2 pairs of whole numbers that multiplied together will be 15:
- 15 x 1 = 15
- 3 x 5 = 15
Answer:
the vertex of the parabola is:(-2,0)
the focus of the parabola is:(-2,
)
the directrix of the parabola is:y=
Step-by-step explanation:
we know that for any general equation of the parabola of the type 
the vertex of the parabola is given by (h,k)
where 
and 
therefore by the given data we have h=-2 and k=0
hence vertex=(-2,0)
the general equation of the parabola of the type 
; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a
so focus is 
now the directrix of the parabola is 
.
Y=1 because on each equation it needs 1 for it to be the answer
