Answer:
the value of hi changes from 58 to 0:
h(t) = -4.9t^2 +19.8t
Step-by-step explanation:
If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.

Step-by-step explanation:
<span>x = number of domestic stamps
y = number of foreign stamps
Malik
collects rare stamps and has a total of 212 stamps.
=> x + y = 212
he has 34 more
domestic stamps than foreign stamps.
=> x = y + 34
which
equation represents the total number of stamps malik collected?
x + y = 212
which
equation represents the difference in the number of foreign and domestic
stamps malik collected?
x - y = 34
which system of linear equations represents the
situation?
x + y = 212
x - y = 34

Answer:the amount that the bookstore pay the publisher for the book is $64.4
Step-by-step explanation:
Let x represent the amount that the bookstore pay the publisher for the book.
The college bookstore marks up the price that it pays the publisher for a book by 35%. This means that the value of the mark up would be
35/100 × x = 0.35 × x = 0.35x
Therefore, the amount that the bookstore is selling the book would be
x + 0.35x = 1.35x
If the selling price of a book is $ 87.00, then it means that
1.35x = 87
x = 87/1.35 = 64.4
