Answer:
y=a(x^2-5x+4)
Step-by-step explanation:
I mean there are a bunch of answers. to figure it out, you can use the formula where you have solved the zeroes in terms of x.
y=(x-1)(x-4)
y=x^2-5x+4
Now if you add any a value to this function, your function will stretch or compress accordingly
y=a(x^2-5x+4)
So there isn't a single correct answer, but if you're looking for a bunch, then just replace the a value with whatever value you want, you'll still get the same answer since they're all proportional to one another.
Answer:
The answer is 20pi
Step-by-step explanation:
perimeter of a semicircle = pi* radius
perimeter of first semicircle = 5.pi
perimeter of second semicircle = 5.pi
perimeter of third semicircle = 10. pi
total perimeter = 5pi +5pi + 10pi
= 20pi
Out of 15 marbles, 3 are yellow, which leaves 12 more marbles that are NOT yellow. 12/15 would be your answer
