The equation of the parabolas given will be found as follows:
a] general form of the parabolas is:
y=k(ax^2+bx+c)
taking to points form the first graph say (2,-2) (3,2), thus
y=k(x-2)(x-3)
y=k(x^2-5x+6)

taking another point (-1,5) 
5=k((-1)^2-5(-1)+6)
5=k(1+5+6)
5=12k
k=5/12
thus the equation will be:
y=5/12(x^2-5x+6)

b] Using the vertex form of the quadratic equations:
y=a(x-h)^2+k
where (h,k) is the vertex
from the graph, the vertex is hence: (-2,1)
thus the equation will be:
y=a(x+2)^2+1
taking the point say (0,3) and solving for a
3=a(0+2)^2+1
3=4a+1
a=1/2
hence the equation will be:
y=1/2(x+2)^2+1

the sides of a triangle are in the ratio 2:3:4. if the measure of the shortest side of the triangle is 12 centimeters what is th
REY [17]
Hello,
We see that there is the ratio
2:3:4, which let us to conclude the ratio between the shortest and longest side is 2:4 or 1:2, so the longest side is two times bigger than the smallest.
To find the longest side:
12×2=24 cm. As a result, the length of the longest side is 24 cm. Hope it help!

35 teenagers were asked what takeaways they liked to eat.
STatiana [176]

The number of teenagers that liked Indian only is 11 students.

<h3>How to use Venn Diagrams?</h3>

Counting students who liked Chinese and pizza

There were 35 teenagers altogether.

  • 24 liked Chinese
  • 16 liked Indian
  • 10 liked pizza

Since all the students who liked pizza also liked Chinese, and no student liked all three, we can just think about the remaining 25 students.

Of these, 14 liked Chinese and 16 liked Indian.

Since each student liked at least one of these, and there are a total of 30 'likes', then 5 students must like both Indian and Chinese.

This leaves 11 students who liked Indian only.

Thus, we conclude that the number of teenagers that liked Indian only is 11 students.
