Answer:

$\boxed{Selling\ Price = Rs.\ 424}$

Step-by-step explanation:

Cost Price = Rs. 400

Profit = 4 % of Cost Price

=> $\frac{4}{100} * 600$

=> 4 * 6

=> Profit = Rs. 24

Now, Selling Price = Cost Price + Profit

Selling Price = 400+24

Selling Price = Rs. 424

Answer:

0.25feet

Step-by-step explanation:

The equation is not well written. Let the equation of the height be modelled as;

h = -16d²+8d+4

The velocity of the ball is zero at its maximum height.

Velocity = change in displacement/time

v = dh/dd

Differentiate

v = -32d+8

Since dh/dd = v = 0

0 = -32d+8

Add 32d to both sides

0+32d = 8

32d = 8

Divide both sides by 32

32d/32 = 8/32

d = 1/4

d = 0.25feet

Hence the maximum height of the tennis ball is 0.25feet

Note that the modeled equation was assumed. You can apply the same calculation to any equation given
