Find the equation of the normal to the curve y=x^2-2x^2-4x+1 at thepoint (-1,2)

balandron [24]

Answer:

$y=-\frac{1}{3}x+\frac{5}{3}$

Step-by-step explanation:

Assuming that the first exponent in the formula for the curve should be 3, not 2...

$y=x^3-2x^2-4x+1$

The derivative is

$y'=3x^2-4x+4$

The slope of the tangent line at the point (-1, 2) is the value of the derivative at x = -1.

$y'|_{x=-1} = 3(-1)^2-4(-1)+4=3-4+4=3$

The slope of the normal line is the opposite reciprocal of the slope of the tangent line.

$m_{\text{normal} = -\frac{1}{3}$

Using the Point-Slope form of a linear equation, the normal line is

$y-2=-\frac{1}{3}(x-(-1))\\y-2=-\frac{1}{3}(x+1)\\y=-\frac{1}{3}x-\frac{1}{3}+2\\y=-\frac{1}{3}x+\frac{5}{3}$

An office administrator earns $16 an hour, and she works 48 hours a week. What is her weekly wage?

Dvinal [7]

If she works 48 hours per week and she earns 16 dollars per hour, we can find the weekly wage by multiplying 48 by 16. This gets us a weekly wage of $768 (Choice A).

Lady_Fox [76]

Answer:

Step-by-step explanation:

The coefficient is the number that comes before the variable

7<u>x</u>+14

In this case, the variable is x.

The number that comes before x is 7, so 7 is the coefficient.

Hope this helps! :)

Calculate the next 3 terms and write the formula for the nth term for the following sequences. x, x+2, x+4,…

Vikki [24]

Answer:

Forth term = x + 6

Fifth term = x + 8

Sixth term = x + 10

Formular for nth term:

${ \tt{n _{th} = a + (n - 1)d}} \\ { \tt{{n _{th} = x + (n - 1) \times 2}}} \\ { \tt{{n _{th} =x + 2n - 2 }}}$
