Answer:
3.
Step-by-step explanation:
Note the prime factorization of 120,
Therefore, there are 3 distinct prime factors, namely 2, 3 and 5.
Answer:
Vertex: V=(0,0)=(h,k)→h=0, k=0
Opens downward:
(x-h)^2=4p(y-k)
Width focal: p=-6<0 (donwnward)
Replacing h=0, k=0 and p=-6 in the equation above:
(x-0)^2=4(-6)(y-0)
x^2=-24y
Answer: The equation of the parabola is x^2=-24y
Step-by-step explanation:
3x is the cost for x notebooks
24*3 is the cost of 24 notebooks
that is 24*3=72
