For this case we have the following function that models the problem is:
The time for which the maximum height occurs is obtained by deriving the equation:
We equal zero and clear x:
The maximum height is obtained by evaluating the time obtained in the given equation:
Then, by the time it reaches the ground we have:
From here, we clear x solving the quadratic equation:
We discard the negative root, and obtain as a result:
Answer:<span>
2.The pumpkin's maximum height is 151.02 feet and it hits the ground after 6.04 seconds </span>
Answer:
If you are to express 5000 in scientific notation form, it would be:
5 ·
Step-by-step explanation:
Looking at it, there is only 1 sig fig (significant figure) and this means if you are to change it to number from between 1 - 10
it would be: 5
so it would look like 5.000 or just 5.
5,000. vs. 5.000 are both completely different things, that are expressed in different ways. But in this case, you can see that we have move the decimal place 3 times, which is why we have
That is how you get your answer!
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
Answer:
A would be the correct answer i believe
Step-by-step explanation:
but im not sure how to explain this though sorry.
:(
Supplementary angles are when both angles sum up to 180
So,
G is 20%*K, so convert to decimals hence,
0.20*k
Hence
0.20*K + K = 180 degrees
