Answer:
Step-by-step explanation:
y=a(x-0)(x-2)
=a(x^2-2x)
=a(x^2-2x+1-1)
or y=a(x-1)^2-a
(1,5) lies on it.
5=a(1-1)^2-a
5=0-a
or a=-5
so y=-5(x-1)^2+5
Answer:
122.67 average
Step-by-step explanation:
Mean = (every value added up)/(# of values)
Mean = (105 + 2(110) + 2(112) + 3(113) + 2(115) + 5(116) + 4(117) + 7(118) + 5(120) + 5(121) + 4(125) + 5(126) + 2(128) + 130 + 3(132) + 134 + 3(135) + 2(140) + 2(141) + 150)/60
= 7360/60
= 122.67
I had trouble understanding the data but I hope I did this right!
Answer:
C is correct.
Step-by-step explanation:
Khan Academy said so.
Do you mean 1/2 of 1/4 if so it’s just timsing the numerator by the numerator and the denominator by the denominator. So, 1 x 1 = 1 and 2 x 4 = 8
Therefore it’s 1/8!
If you didn’t understand I’ll gladly elaborate!
