ANSWER

It is horizontally compressed by a factor of 2 and reflected over the y-axis.

EXPLANATION

The parent function given to us is

y = \sqrt{x}

The parent function has been transformed to obtain

y = \sqrt{ - 2x}

This transformation is of the form:

y = \sqrt{kx}

If

|k| > 1

then,there is a horizontal compression by a factor of k.

Hence

y = \sqrt{ - 2x}

is horizontally compressed by a factor of 2.

Since -2<0, it is a reflection in the y-axis.

The correct choice is the last option.

Question: What is the volume of the box? Explain how you found your solution.
Vikki [24]

The volume of the box is 100 cubic meter.

Step-by step explanation:

Given data:

Length of the box = 10 m

Width of the box = 5 m

Height of the box = 2 m

<u>To find the volume of the box:</u>

Volume of the box = length × width × height

                               = 10 m × 5 m × 2 m

                               = 100 cubic meter

Hence the volume of the box is 100 cubic meter.

in 2014 the attendance at jefferson schools fall festival was 650 in 2015 the attendance was 575 what was the percent change
Gnoma [55]

There was 11.54% decrease in attendance.

Step-by-step explanation:

Attendance in 2014 = Old value = 650

Attendance in 2015 = New value = 575

Change = New value - Old value

Change = 575 - 650 = -75

The negative sign indicates a decrease in attendance.

Decrease percentage = \frac{Change}{Old\ value}*100

Decrease\ percent=\frac{75}{650}*100\\\\Decrease\ percent=\frac{7500}{650}\\\\Decrease\ percent=11.538\%

Rounding off to nearest hundredth

Decrease percent = 11.54%

There was 11.54% decrease in attendance.
