Answer:
Option D
Step-by-step explanation:
Rate of change of a linear function between two points
and
is given by,
Rate of change 'm' = 
From the given table,
Rate of change of the function between (-2, 6) and (-4, 9),
Rate of change 'm' = 
m = 
Initial value = y-intercept
Let the equation of the line passing through a point (h, k) is,
y - k = m(x - h)
If a point (-2, 6) is lying on the graph of the function,
y - 6 = 
y = 
y = 
Y-intercept of the function = 3
Therefore, initial value of the function = 3
Option D is the answer.
Answer: C
Step-by-step explanation:
Reflecting over the x axis, the image of a point in Quadrant 2 is a point in Quadrant 3.
The triangle formed from the height of the cone and the radius of its base is a special 3,4,5 triangle. The slant height is 5cm.
Recall that the area of a circle = pi*r^2
Substitute 3 in for r
Area = pi * (3)^2 = 9pi
SA = pi*r*l + B
Substitute our values into the equation
SA = pi * 3 * 5 + 9pi
SA = 15pi + 9pi
SA = 24pi cm^2
