Describe the behavior of the function ppp around its vertical asymptote at x=-2x=−2x, equals, minus, 2.

insens350 [35]

Answer:

$x->-2^{-}, p(x)->-\infty$ and as $x->-2^{+}, p(x)->-\infty$

Step-by-step explanation:

Given

$p(x) = \frac{x^2-2x-3}{x+2}$ -- Missing from the question

Required

The behavior of the function around its vertical asymptote at $x = -2$

$p(x) = \frac{x^2-2x-3}{x+2}$

Expand the numerator

$p(x) = \frac{x^2 + x -3x - 3}{x+2}$

Factorize

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

Factor out x + 1

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

We test the function using values close to -2 (one value will be less than -2 while the other will be greater than -2)

We are only interested in the sign of the result

----------------------------------------------------------------------------------------------------------

As x approaches -2 implies that:

$x -> -2^{-}$ Say x = -3

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

$p(-3) = \frac{(-3-3)(-3+1)}{-3+2} = \frac{-6 * -2}{-1} = \frac{+12}{-1} = -12$

We have a negative value (-12); This will be called negative infinity

This implies that as x approaches -2, p(x) approaches negative infinity

$x->-2^{-}, p(x)->-\infty$

Take note of the superscript of 2 (this implies that, we approach 2 from a value less than 2)

As x leaves -2 implies that: $x>-2$

Say x = -2.1

$p(-2.1) = \frac{(-2.1-3)(-2.1+1)}{-2.1+2} = \frac{-5.1 * -1.1}{-0.1} = \frac{+5.61}{-0.1} = -56.1$

We have a negative value (-56.1); This will be called negative infinity

This implies that as x leaves -2, p(x) approaches negative infinity

$x->-2^{+}, p(x)->-\infty$

So, the behavior is:

$x->-2^{-}, p(x)->-\infty$ and as $x->-2^{+}, p(x)->-\infty$

Jack and Jill applied for the same credit card from the same bank. The bank checked both of their FICO scores. Jack had an excel

iren [92.7K]

Answer:

a. Jack's monthly periodic rate = 1%

b. Jill's monthly periodic rate = 1.75%

c. Amount paid more by Jill than Jack = $5.25

Step-by-step explanation:

a. Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?

Jack's monthly periodic rate = Jack's annual percentage rate (APR) / Number of months in a year = 12% / 12 = 1%

b. Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?

Jill's monthly periodic rate = Jill's APR / Number of months in a year = 21% / 12 = 1.75%

c. If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Jack's finance charge = Jack's monthly periodic rate * Average daily balance = 1% * $700 = $7

Jill's finance charge = Jill's monthly periodic rate * Average daily balance = 1.75% * $700 = $12.25

Amount paid more by Jill than Jack = Jill's finance charge - Jack's finance charge = $12.25 - $7 = $5.25

The product of 9 and a number decreased<br> by ten in an algebraic formula

lapo4ka [179]

Answer:

9n -10

Step-by-step explanation:

If n represents the number, the product of the number and 9 is 9n. That value decreased by 10 is ...

9n -10

_____

<em>Additional comment</em>

The English expression is ambiguous in that we cannot tell if the number is decreased by 10 before becoming part of the product (9(n-10)), or if the correct interpretation is the one shown above. The order of operations is used as a guide, telling us that the multiplication is done before the subtraction since there is no indication of grouping.
