Answer:

Step-by-step explanation:

Given a function f(x) where the first derivative with respect to x evaluated in two equals

f'(2)=1/2

The slope of the tangent line is

mt=1/2

Therefore, the slope of the normal line is

mn=-1/(1/2)

mn=-2

Evaluating the given point in the general form

y-y1=m(x-x1)

y-(-1)=-2(x-2)

y+1=-2x+4

y=-2x+3

How much work is done when a taxi driver lifts a 100N100N suitcase 0.7m0.7m into the trunk of his cab

Rudiy27

Answer:

70 joules

Step-by-step explanation:

We have the following information

100N and 0.7 m

What is workdone?

We say that Work is done if a force which is applied to an object is able to move that object. We calculate the value of The work by multiplying the force by what is known to be the movement of the object.

(Workdone = Force x distance).

A force of 100 newtons, in this question moves an object 0.7 meters

Workdone =

100N x 0.7

= 70 joules

Thank you!

A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.75 mi long. You walk acro

Sergio [31]

C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.

You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer

Solve the equation by completing the square

Ilya [14]

Answer:

We got the quadratic equation:

$x^2+8x-3=0$

Solving by completing the square:

$x^2+8x-3=0\\x^2+8x+16-16-3=0\\(x+4)^2-16-3=0\\(x+4)^2-19=0\\(x+4)^2=19\\x+4=\pm \sqrt{19} \\x=-4\pm \sqrt{19} \\\\x_{1} =-4+\sqrt{19} \\x_{2} =-4-\sqrt{19}$

Therefore, the answer is letter C
