Answer:
k = -2
Step-by-step explanation:
f(x) = (x − h)² + k
(h, k) is the (x, y) coordinate of the vertex
For a vertex of (4, -2)
h = 4
k = -2

Step-by-step explanation:
We have to determine the number of cubic centimeters in 5.78 cubic yards.
Since there are 764555 cubic centimeters in 1 cubic yard.
To convert cubic yard to cubic centimeters, we have to multiply the given cubic yards with 764555.
Therefore, 5.78 cubic yards
= 
= 4419127 cubic centimeters
Therefore, there are 4419127 cubic centimeters in 5.78 cubic yards.
Answer:
There are 14 new books and 22 old books in the package.
Step-by-step explanation:
New books cost $20 and used books cost $8. The bookstore wants to sell packages that have 36 books total, and the store charges $456 for each package.
If the number of new books in the package is x and that of old books in the package is y, then we can write two simultaneous equations as
x + y = 36 ........... (1) and
20x + 8y = 456
⇒ 5x + 2y = 114 ............ (2)
Now, solving equations (1) and (2) we get,
5x + 2(36 - x) = 114
⇒ 3x + 72 = 114
⇒ 3x = 42
⇒ x = 14
Then, y = 36 - x = 22.
Therefore, there are 14 new books and 22 old books in the package. (Answer)
