Answer:
Step-by-step explanation:
I don't know if you are a calculus student, but since calculus is the easiest way to solve this, that's what I used. The position equation is
and the velocity function, the first derivative, is
From Physics, you should know that the velocity of an object is 0 at its highest point. That means that if we sub in a 0 for the velocity and solve for t, we find the time at which the object is at its highest point. That is:
and
By the Zero Product Property,
-12 definitely does not equal 0, so that means that
t - 2 = 0 and
t = 2 seconds.
So at 2 seconds, the object is at its highest point. Go back to the position function now and sub in a 2 for t to find the height of the object at 2 seconds.
so
s(2) = 38 meters
27 = 3 × 9
35 = 5 × 7
51 = 3 × 17
So answer would be 5, 11, 31.
Hi there!
Thanks for asking for help!
I believe Part A of your answer is the expression: n+2n.
Because that is the answer for Part A, Part B is the answer: "The expression for the bookcases is n+2n because the problem says 'the larger bookcase holds twice as much as the smaller one,' and 'let n represent the amount of books the smaller bookcase holds'.
Since you need to find an expression for the amount both bookcases needs to hold you would add n (capacity of the smaller bookcase) and 2n (capacity of the larger bookcase) together to have an expression that represents the amount both hold.
Part C: 90=3n
I know this is the correct equation based on the expression written above since n+2n=3n, and the problem says "the amount both bookcases hold together is 90 books"
btw, bookcase 1 holds 30 books and the large bookcase holds 60.
Hope this helps you out! :)
