Answer:
Step-by-step explanation:
Use distance formula to get a distance function in terms of x representing the distance from a point on curve (x,y) to point (3,0)
y = 8/x
Minimize the function by setting derivative equal to 0.
Simplify and solve for x
This becomes a 4th degree polynomial, you can use graphing calculator to find zeros.
Also intuitively you can recognize that 64 = 4^3, so if x=4 you get
1 = 1
Therefore x=4 is a solution, substituting give y =2
Answer:
y=-3x+50
Step-by-step explanation:
y=50-3x ,where x is number of days.
Answer:
A=6x²
Step-by-step explanation:
A cube is an object which is three-dimensional. A cube has six square faces.
If the side length = x inches
The area of a square = x²
Therefore, the expression for the surface area of a cube(with 6 square faces) with a side length of x is given as:
A=6x²
