4 0

Answer:

12/100 = x/350

4200 = 100x

4200/100 = 100x/100

42 = x

350 - 42 = 308

the sale price is $308

the discount is $42

Find the average rate of change of the number of digital cameras sold from 2006 to 2015
asambeis [7]

Answer:

5900 units per year  

Step-by-step explanation:

The average rate of change  from (x₁, y₁) to (x₂, y₂) is the slope of the straight line joining the two points.

slope = (y₂ - y₁)/(x₂ - x₁)

From the graph, I estimate your points to be (2006, 35 000) and (2015, 88 000).  

slope = (88 000 - 35 000)/(2015 - 2006) = 53 000/9 ≈ 5900 units per year

The  average rate of change in the number of digital cameras sold between 2006 and 2015 was 5900 units per year.

The formula κ​(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a​ twice-differentiable plane curve as a function of x. Use thi
Katyanochek1 [597]

Answer:

K(x) =  \frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }    ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = -5x^2

first Determine the value of F'(x)

F'(x) = \frac{d(-5x^2)}{dy}

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = \frac{d(-10x)}{dy}

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x)  = \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }

 K(x) =  \frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }    ( curvature function)
