Answer:
Horizontal distance, d = 9.146
Step-by-step explanation:
The given function is
The horizontal distance, d, is the distance on ground. So, set f(d) = 0.
That is, a height of zero which becomes the ground level.
Using the quadratic formula:
Thus, the ball is in air between d=-0.146 to d=9.146.
Since the distance can not be negative, the ball remains in the air between d = 0 to d = 9.146.
Therefore d = 9.146
Answer:
5. Profit of Rs 1 per lemon
6. Rs 20
Step-by-step explanation:
5. Buy Rs 60 per 12 lemons = Rs 5 per lemon
Sell Rs 30 per 5 lemons = Rs 6 per lemon
Profit Rs 1 per lemon
6. Sell Rs 2500 per 100 pens = Rs 25 per pen
Profit per pen is 20% = (20/100)25 = 5
Cost price of a pen = 25 - 5 = 20
If each slice turns a right angle that means it turns 90* so you can only have two turns per pizza which gives 4 slices (90+90+90+90=360 - this is how many degrees in a circle) so per pizza 4 slices. For four pizzas that is 4x4 which is 16 so 16slices
