If 5-y^2=x^2 then find d^2y/dx^2 at the point (2, 1) in simplest form. ​
ratelena [41]

Answer:

y"(2, 1) = -5

Step-by-step explanation:

Step 1: Define implicit differentiation

5 - y² = x²

Step 2: Find dy/dx

  1. Take implicit differentiation: -2yy' = 2x
  2. Isolate y': y' = 2x/-2y
  3. Isolate y': y' = -x/y

Step 3: Find d²y/dx²

  1. Quotient Rule: y'' = [y(-1) - y'(-x)] / y²
  2. Substitute y': y" = [-y - (-x/y)(-x)] / y²
  3. Simplify: y" = [-y - x²/y] / y²
  4. Multiply top/bottom by y: y" = (-y² - x²) / y³
  5. Factor negative: y" = -(y² + x²) / y³

Step 4: Substitute and Evaluate

y"(2, 1) = -(1² + 2²) / 1³

y"(2, 1) = -(1 + 4) / 1

y"(2, 1) = -5/1

y"(2, 1) = -5

Given g(x) where f(x)= 3x-1 and g(x)= f(x+1). graph
tatiyna

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=3x-1

we know that

To find out the function f(x+1) exchange the variable x for (x+1) in the function f(x)

so

f(x+1)=3(x+1)-1

f(x+1)=3x+3-1

f(x+1)=3x+2

therefore

g(x)=3x+2

using a graphing tool

see the attached figure

Company 1: (24 + 26 + 28 + 23 + 21) / 5 (this is how many numbers added together) = 24.4

Company 2: (6 + 32 + 9 + 31 + 21) / 5 = 19.8

Company 3 (15 + 15 + 15 + 15 + 15) / 5 = 15

Company 4: (13 + 10 + 45 + 12 + 15) / 5 = 19

Company 1 has the longest average commute time per employee.
