Answer:
It costs $0.216 to make smaller can and $0.324 to make larger can
Step-by-step explanation:
Given:
The ratio of the surface areas = 4:9
Area of smaller cans = 36 sq in
Cost = $0.006 per square inch
To Find:
how much does it cost to make each can = ?
Solution:
Lets the area of the larger can be x
the ratio is 4 : 9
then 4x = 9.(36)
4x = 216
x = 54
The area of the larger can is 54 sq in
Now the cost of making the smaller can = = $0.216
The cost of making the Larger can = =$0.324
<h3>Explanation:</h3>
It appears that the function f(x) is ...
f(x) = 1/(x -2)
The function g(x) can be rewritten as ...
g(x) = 8/(x -2) +3 = 8f(x) +3
So, the graph of g(x) will be the graph of f(x) scaled vertically by a factor of 8, then shifted upward 3 units.
First off, we need the slope
<u /><u />
That leaves you with
12/3 = 4
<em><u>point-slope form: </u></em> y-y1 = m ( x - x1)
So...
y - (-4) = 4 ( x - (-2))
y + 4 = 4 (x + 2)
y + 4 = 4x + 8
Now subtract 4 from both sides of the equation
y = 4x +4
