The given function is
According to this function, the starting height of the rocket is 20 feet because that's the initial condition of the problem stated by the independent term.
Additionally, we find the maximum height by calculating the vertex of the function V(h,k).
Where a = -16 and b = 300.
Then, we find k by evaluating the function
Hence, the maximum height is 1426.25 feet.
At last, to know the time need to hit the ground, we just use h=9.375 and we multiply it by 2
Hence, the rocket hits the ground after 18.75 seconds.
Answer:
<u> </u><u>For</u><u> </u><u>y</u><u> </u><u>:</u>
From pythogras theorem:
For the second largest inner triangle;
Equate (a) and (b):
solve the equation to get values of x, which will give you y
-3.2+(-4.6)+5.4
when you add a negative number it is the same as just subtracting it.
-3.2-4.6+5.4
-3.2-4.6 can be done like this: -(3.2+4.6) making it -7.8
-7.8+5.4
-7.8+5.4 can be done like this -(7.8-5.4) making the final answer-2.4
Hope this helps :)
Answer:
The end of the 7th day of a week would be Sunday.
Monday-1st FULL day
Tuesdau-2nd FULL day
on so on
Therefore, it would not be 7.99 days and instead a full ONE day
hopefully this makes some sense
Answer:
To round off a number to 2 decimal places, look at the digit in the thousandths place. If the digit in the thousandths place is greater or equal to 5, the hundredths digit is increased by one unit.
