The equation of the normal line

Advanced Placement (AP)
1 answer:

Answer:

D. y = 1/2x + 3/2

Explanation:

You probably already know the point slope equation:

y = m(x - x₀) + y₀

All you need is the slope and the (x₀, y₀).

The (x₀, y₀) could be solved by plugging in the given x=-1 value into the function.

m, the slope, is the same as a derivative; ie. a derivative is a slope.

So solve for the derivative and find the slope at x=-1.

Plug into point slope equation and simplify.

A rectangle has a perimeter of 20 inches and an area of 24 square inches. What are the length and width of the rectangle?
s2008m [1.1K]
Perimeter = 2(L + W) = 20 or L + W = 10

And Area = L x W = 24

So with have the SUM "S" of 2 numbers and te PRODUCT "P' of same numbers, then

we can apply te quadratic equation X² -SX + P

X² - 10X + 24 = 0, solve this equation and you'll find L = 6 in and W = 4in

 or 4 in x 6 in

How is the idea of home represented regionally, locally and globally?
myrzilka [38]
Regionally, a home may be a general region, such as the south. Locally, this will be something on a much smaller scale such as your hometown. Globally, this will usually be a nation as your home.

Example -

My regional home is the south, my local home is Smallville, and my global home is the United States.

Hopefully, this helps! I'm a bit iffy on my answer, but I hope it satisfies you! =)
