In any function y = f(x) , set of all possible values of x define the domain of f(x), in the graph The curve in terms of x-axis(in 1st & 3rd quadrant) goes from -4 to -2(doesnt include -2).

So domain = [-4, -2)

Similarly, in 2nd and 4th quadrant, for x-axis

It goes from 2 to 5 (doesnt include 2 & 5)

So domain = (2, 5)

Hence,

Domain of the f(x) is [-4, -2) U (2, 5).

Range tells the possible values of y, for this function it goes from -5 to +3(doesnt include 3).

Range is [-5, 3)

1. What is the slope of the following Table?

qaws [65]

It should be 2, because your adding 2 each time for the y value. When your finding slope it’ll always be the change in y over the change in x. Hope this helps!!

Which of the following is an equation of a circle in

DaniilM [7]

Answer:

$x^2 + (y - 4)^2 = \dfrac{25}{9}$

Step-by-step explanation:

The equation of a circle with center at (h, k) and radius r is

$(x - h)^2 + (y - k)^2 = r^2$

You have center (0, 4).

We get:

$(x - 0)^2 + (y - 4)^2 = r^2$

$x^2 + (y - 4)^2 = r^2$

To find the radius, we use the distance formula to find the distance from the center of the circle to the given point on the circle.

$r = d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$r = \sqrt{(\dfrac{4}{3} - 0)^2 + (5 - 4)^2}$

$r = \sqrt{(\dfrac{4}{3})^2 + 1^2}$

$r = \sqrt{\dfrac{16}{9} + \dfrac{9}{9}}$

$r = \sqrt{\dfrac{25}{9}}$

We need r^2 in the equation of the circle, so

$r^2 = \dfrac{25}{9}$

The equation of the circle is

$x^2 + (y - 4)^2 = \dfrac{25}{9}$

A company has two manufacturing plants with daily production levels of 5x+14 items and 3 x-5 items, respectively. The first plan

xxTIMURxx [149]

Answer:

$2x+19$

Step-by-step explanation:

The first is $5x+14$

The second is $5x-5$

So $5x+14-(5x-5)=2x+19$

The histogram displays the number of 2012 births among U.S. women ages 10 to 50 . Each bin represents an interval of two years,

Advocard [28]

Answer:

Number of births to women below 22 years of age: 830

% of births occurred to women of age between 34 and 36: 6.35%

Step-by-step explanation:

There are two parts to this question:

To calculate the number of births, we look at the histogram below.

We see that each bar has a number on top, suggesting that particular for the age limit. Number of births to women below age of 22, we start adding all numbers below the mark of 22 on x-axis:

⇒ 39+134+29+363 = 830

To calculate the percentage, we divide the number of births in that particular interval by total number of births and then multiply by 100.

To calculate the total number of births, we add all the numbers on the top of the bars:

⇒ 39+ 134+294+363+391+425+460+474+432+343+250+163+98+49+17+4+1 Total births = 3937

$\frac{250}{3937} \times 100\\ 0.0635 \times 100\\= 6.35 \%$
