Answer:
EASY the awnser is about 15
Answer:
B)max/ opens down
Step-by-step explanation:
Parabola equation:
The equation of a parabola has the following format:

If
, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.
If
, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.
In this question:

From the graph, we already see that it opens down and has a max, and analitically, since
, this is confirmed. The correct answer is given by option b.
Answer:
Avoid guessing or choosing an answer you are unsure of. Remember, you’ll only get the extra points if you give the correct answer.
Step-by-step explanation:
Answer:
As the first part comes to the rest means, then it will fall under gravity directly.
First of all maximum height,
H=
g
u²sin²θ
H=
2×10
400×(

1
)
H=10m.
As initially the full projectile was supposed to land at A but due to explosion first part land at A', so to make the centre of mass lies at A the second part should lie at B.
f they don't break (explode) range OA
OA=
g
u²sin2θ
OA=400×sin45×

Answer:
x <u>></u> 6
Step-by-step explanation:
If it is at most 6 then it could be equal to or less than 6 but not more so it would be a <u>></u>.
For example: If you had 6 dollars to spend at the store and you want to buy some candy. You can only buy something that is less than or equal to 6 dollars or else you wouldn't have enough money. Though this example would be different in real life bc of tax, it is the same type of thing.
