Answer:
the domain of given f is (-2,4)
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m is the slope and b is the y intercept. We are given a slope of three so
y=3x+b, using point (1,3) we can solve for b
3=3(1)+b, 3-3=0 so b=0 then our line is
y=3x
The x intercept is when y=0 and this occurs when x=0 or the point (0,0)
The y intercept occurs when x=0, this occurs when y=0 or the point (0,0)
Answer:
<h3><u>$480</u></h3>
Step-by-step explanation:
<u>You divide $800 by 5 and get $160. Then multiply $160 by 2 and get $320. Then subtract $320 from $800 and get $480.</u>
Step-by-step explanation:
A)
The length of the box is 30 − 2x inches.
The width of the box is 30 − 2x inches.
The height of the box is x inches.
So the volume is:
V = x (30 − 2x)²
B)
V(3) = 3 (30 − 6)² = 1728
V(4) = 4 (30 − 8)² = 1936
V(5) = 5 (30 − 10)² = 2000
V(6) = 6 (30 − 12)² = 1944
V(7) = 7 (30 − 14)² = 1792
As x increases, the volume of the box increases to a maximum and then decreases.
C)
The ends of the domain occur when V = 0.
0 = x (30 − 2x)²
x = 0 or 15
So the domain is (0, 15).
