Answer:
Equation: y = -0.5x + 2.
Step-by-step explanation:
The question says the machine uses up m gallons of oil each hour on weekends.
This means that if the machine works for 24 hours each day, it implies that:
There are only two days on weekends i.e. Saturday and Sunday.
This means that if the amount of oil used in 1 day in the weekend is 24m, then we can say:
Saturday: oil used is 24m
Sunday: oil used is 24m
Total oil used during the weekend is:
Answer:
3.8
Step-by-step explanation:
"Let the art prints be p
Cost function is 38 + 2p
Revenue function is 12p
Set cost equal to revenue
12p = 38 + 2p
Subtract 2p from each side
10p = 38"
The form of an eclipse is written as:
(x-h)^2/b^2 + (y-k)^2/a^2 = 1
Matching the values in the given equation tot he form of an eclipse you have:
a = 6
b = 4
k = 0
h = 0
A is the radius of the major axis and b is the radius of the minor axis.
H is the X offset and K is the Y offset.
The first vertex is written as (h, k+a)
Replacing the letters with their values you get:
(0, 0+6) = (0,6)
The second vertex is written as (h, k-a)
Replacing the letters with their values you get:
(0, 0-6) = (0,-6)
The vertices of the are (0,6) and (0,-6)
The vertices are the end points of the major axis, since 6 and -6 are longer than the minor axis of -4, 4 the ellipse has a vertical major axis
