Step-by-step explanation: Please find the attached files for the solution
Answer:
80
Step-by-step explanation:
We let x be Ann's savings.
Betty saves 3 times as much as Ann.
This implies that Betty's savings in terms of x
Charles save 390 less than Ann.
This implies Charles savings
Betty saves 1330 more than Charles.
This implies that when we deduct Charles savings from Betty's we have to get 1330.
Mathematical equation for the problem:
Expand :
Subtract 390 from both sides.
Divide through by 2
Hence Charles saving is
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
