A

In 1995 the population was slightly above 250,000,000

Elza [17]3 years ago

Answer:

a. 250, 000, 000

Step-by-step explanation:

First, you locate 1995 on the x axis, which is in between 1990 and 2000. Then, you go straight up until you touch the line, which is right above 250, 000, 000.

Or Process of elimination:

Since it's going upward, it can't be 150, 000, 000. Since 200, 000, 000 is 1970 it has to be higher, since the line is at an angle. Which leaves us with 2 answers. 300, 000, 000 is above 2009, that leaves us with A. 250, 000, 000

If f(x)=x^2+3x+4 which of the number choices represents (f(x+h)-f(x))/h?

Helen [10]

In case you're not already aware, the expression $\frac{f(x+h)-f(x)}h$ is called the "difference quotient" and represents the average rate of change of a function $f$ over an interval $[x,x+h]$ .

For the function $f(x)=x^2+3x+4$ , by substituting $x+h$ we get

$f(x+h)=(x+h)^2+3(x+h)+4=(x^2+2xh+h^2)+(3x+3h)+4=x^2+3x+4+(2x+3)h+h^2$

Then the difference quotient is

$\dfrac{f(x+h)-f(x)}h=\dfrac{(x^2+3x+4+(2x+3)h+h^2)-(x^2+3x+4)}h$

$=\dfrac{(2x+3)h+h^2}h=2x+3+h$

where the last equality holds as long as $h\neq0$ .

Lynn is a single mother with two children's . She qualifies to file as head of household her total income was $27267 last year h

storchak [24]

Answer:

$3,078.04

Step-by-step explanation:

-Given her income is $27,267, she falls under the 10% and 12% brackets with the following boundaries as attached.

-Her tax is then calculated as;

#10% bracket;

$Tax=Taxable \ Income \times Tax \ Rate\\\\=9700\times 10\%\\\\\\=\$970.00$

#12% Tax bracket:

$Tax=Taxable \ Income \times Tax \ Rate\\\\=(27267-9700)\times 12\%\\\\\\=\$2108.04$

The total tax=970+2108.04=$3,078.04

Hence, Lynn owes $3,078.04 in taxes.

What does the ordered pair (6, 204) represent in this situation?

maxonik [38]

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
