For
choose the correct substitution for a, b, and c in the general form of

a. a=1,b=1, c=5

​b. a-1,b=0, c=5

c. a=1,b=0,c=-5

d. a=1,b=5, c=0

the answer is 8/21

hope this

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
