Answer:
J' : (8, 1)
K' : (5, 1)
L' : (3, 6)
M' : (0, 6)
Step-by-step explanation:
the rule for reflection over the y-axis is (x, y) → (-x, y)
therefore:
J' : (8, 1)
K' : (5, 1)
L' : (3, 6)
M' : (0, 6)
Correct question is;
A football is kicked up into the air. Its height, H, above the ground, in meters, at t seconds can be modelled by () = 24 − 4.9²
(a) Determine the expression for the instantaneous rate of change in height at time t.
(b) Determine ' (2) What does ' (2) represent?
Answer:
A) '() = 24 − 9.8
B) '(2) = 4.4 m/s
It means that at a distance of 2 m above the ground, the speed of the ball is 4.4 m/s
Step-by-step explanation:
We are given the function to represent the height as;
() = 24 − 4.9²
A) expression for the instantaneous rate of change in height at time t will be gotten by differentiation of the height function. Thus;
'() = 24 − 9.8
B) '(2) = 24 - 9.8(2)
'(2) = 4.4 m/s
This means that at a distance of 2 m above the ground, the speed of the ball is 4.4 m/s
Y=-1/2x+3 is the slope intercept form.
