Step-by-step explanation:
Take the LCM of the denominators:
=> LCM = 18
=> -7/9 x 2/2 = -14/18
=> -4/9 x 2/2 = -8/18
=> 1/9 x 2/2 = 2/18
=> 1/2 x 9/9 = 9/18
When the number is negative, the greater the number, the smaller it is.
So, -14 is smaller than -8.
< = smaller than
=> -14/18 < -8/18 < 2/18 < 9/18
=> -7/9 < -4/9 < 1/9 < 1/2
Answer:
V = 23.85 ft³
Step-by-step explanation:
The dimension of the square base = x ft by x ft
Height of box = y
Volume of the box, 
Cost of top = $4 * 
Cost of the bottom = $9 * 
Cost of the sides = $3 * 4xy
Total cost = 4x² + 9x² + 12xy
Total cost = 13x² + 12xy
Total cost = $193
193 = 13x² + 12xy

But volume, V = x²y
V = 
V =
...................(1)
At maximum value, V' = 0
0 = 

x = 2.23
Put the value of x into (1)

V = 23.85 ft³
DOMAIN:
- Set of allowable inputs (set of 1st elements of the ordered pairs in relation)
- X point
- AKA the input
DEFINE INPUT:
A number that'll be used in a function rule to determine the value of the output
RANGE:
- Set of possible outputs (set of 2nd elements of the ordered pairs in relation)
- Y point
- AKA the output
DEFINE OUTPUT:
Result of applying a function rule to the value of ani input
ORDERED PAIRS:
(-1, 7): -1 is the domain & 7 is the range
(3, 5): 3 is the domain & 5 is the range
(4, 9): 4 is the domain & 9 is the range
(-6, -10): -6 is the domain & -10 is the range
(-2, 8): -2 is the domain & 8 is the range
Hope this helps you!!! :)
