Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27

icang [17]

Answer: B) 1/9, 3, 27

Step-by-step explanation:

Here, we need to evaluate $3^x$ for $x = -2, x = 1, \text{ and } x = 3.$

So, we substitute values of x in the given function.

At x= -2, we have

$3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]$

At x= 1, we have

$3^1=3$

At x= 3

$3^3=3\times3\times3=27$

So, the values of $3^x$ for

Thus, the correct answer is B) 1/9, 3, 27

Caren held 260 of the shares for herself and sold the rest in equal amounts to six investors. How many shares does each investor

notsponge [240]

Answer:

40 shares each and $3,000 each

Step-by-step explanation:

The computation is shown below:

For the number of shares

Since there are total of 500 shares out of which 260 shares are held by Caren so the remaining shares left is

= 500 shares - 260 shares

= 240 shares

And, there are 6 investors

So the number of shares owned by each investor is

$= \frac{240}{6}$

= 40 shares

Now the value of the shares held by each inventory is

$= 40 shares \times \$75$

= $3,000

Total debt is $65,000

So, the liability per share is

$= \frac{\$65,000}{500}$

= $130

And each investor holds 40 shares

So, each investor is liable for

$= \$130 \times 40\ shares$

= $5,200

As we can see that the value of the shares is less than the amount liable by each investor

So each investor is liable for $3,000

And, the liability of Caren is

$= 260\ shares \times \$75$

= $19,500

Maggie graphed the image of a 90° counterclockwise rotation about vertex A of △ABC. Coordinates B and C of △ABC are (2, 6) and (

Vitek1552 [10]

Answer:

A(2, 2)

Step-by-step explanation:

I find it useful to graph the given points. The center of rotation is at the place where the perpendicular bisectors of BB' and CC' meet. That point is ...

A = (2, 2).

The graph shows you the slope of BB' is 1, so its perpendicular bisector will have a slope of -1. The midpoint of BB' is (2-2, 6+2)/2 = (0, 4). This is the y-intercept of the line, so the perpendicular bisector of BB' has equation ...

y = -x +4

The slope of CC' is -1/3, so its perpendicular will have a slope of -1/(-1/3) = 3. The midpoint of CC' is (4+1, 3+4)/2 = (5/2, 7/2). In point-slope form the equation of the perpendicular bisector of CC' is ...

y -7/2 = 3(x -5/2)

2y -7 = 3(2x -5) . . . . multiply by 2

2(-x+4) -7 = 3(2x -5) . . . substitute for y

-2x +1 = 6x -15 . . . . .eliminate parentheses

16 = 8x . . . . . . . . . . add 2x+15

x = 2 . . . . . . divide by 8

y = -2+4 = 2 . . . . from the equation for y

The intersection of the perpendicular bisectors of BB' and CC' is the center of rotation:

A = (2, 2)
