The roots of a quadratic function are the points at which the cross the x axis (the x- intercepts). so your roots are
(3) 3 and -6
Answer:
For mean
To show the mean of height measures for 40 students, you need to write-out exactly 40 heights into a calculator and add them up.
Then divide that total number by 40.
Step-by-step explanation:
Eg for 4 students
5 , 5.1, 5.2, 5.7 = 21ft
21/4 = 5.25ft.
Apply the same method but use 40 measures in addition for calulator or long addition. Then divide by 40.
Y=-4
X=2
Yeah that’s all I got to say lol
The answer is Set Y. Because 6 / 6 = 1.
24 / 6 = 4.
36 / 6 = 6.
78 / 6 = 13.
84 / 6 = 14.
Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = 
r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = r²h
V = (2²)(4)
V = 16
V = 50.3 cm³
