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 this formula to find the curvature function of the following curve. ​f(x)=−5x2 The curvature function is κ​(x)=nothing.

Answers

Answer:

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

Step-by-step explanation:

considering the Given function

F(x) = [tex]-5x^2[/tex]

first Determine the value of F'(x)

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

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = [tex]\frac{d(-10x)}{dy}[/tex]

F" (x) = -10

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

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

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

write a real-world problem in which two negative integers are subtracted​

Answers

Problem:

Mary was 12 (-12) feet below sea level, she sawm down another 5 feet (-5). How many feet below sea level is Mary?

(if needed) Answer: -17

The real-world problem in which two negative integers are subtracted​ is a person diving below the surface of a sea for 60 feet and 50 feet.

-60 - 50 = -110.

110 feet below the surface of the sea.

We have to write a real-world problem in which two negative integers are subtracted​.

Let us consider that a person is at the surface of a sea before he dives deep.

The person started to dive below the surface and he was now 60 feet below the surface.

Again he started to dive deep to 50 feet below.

So the person is at how many feet below the surface: - 60 - 50 = -110 feet.

The person is 110 feet below the surface.

And -60 and -50 are the two negative integers subtracted.

Thus,

The real-world problem in which two negative integers are subtracted​ is a person diving below the surface of a sea for 60 feet and 50 feet.

-60 - 50 = -110.

110 feet below the surface of the sea.

Which of these steps will eliminate a variable in this system? 4x-9y=8 2x+3y=24

Answers

For eliminate a variables we need addition method or elimination method.

Define the term Variable?

In an equation or formula, a variable is a symbol or letter that stands in for an unknowable or varying quantity or value.

We can multiply the second equation by -2, so that the coefficient of x in both equations will be the same but with opposite signs:

⇒ 4x - 9y = 8

⇒ -4x - 6y = -48

Add the two equations together: ⇒ -15y = -40

⇒ y = 8/3

Substitute this value of y back into either equation to solve for x.

⇒ 4x - 9(8/3) = 8

⇒ 4x - 24 = 8

⇒ x = 8

Therefore, the steps to eliminate a variable in this system using the addition method are to multiply the second equation by -2, add the two equations together to eliminate the x variable, solve for y, and then substitute that value back into either equation to solve for x.

g(x) = x^3

(f • g)(x) = (3x+2)(x^3)
(f • g)(x) = 3x^4 + 2x^3
(f • g)(-5) = 3(-5)^4 + 2(-5)^3
(f • g)(-5) = 3(625) + 2(-125)
