Answer 1

Answer:

Answer:

distributive property

Step-by-step explanation:

Given that

The voltage V of an audio speaker can be represented by $\rm V = 4√(P)$ .

Where P is the power of the speaker.

An engineer wants to design a speaker with 361 watts of power.

We have to determine

What will the voltage be of an audio speaker?

According to the question

The voltage V of an audio speaker can be represented by $\rm V = 4√(P)$ .

The power of the audio speaker = 361 watts

The voltage of an audio speaker is;

$\rm V = 4√(P)\n\n\rm V = 4√(361)\n\nV = 4 * 19\n\nV = 76$

Hence, the voltage of an audio speaker is 76 volts.

Answer:

$Voltage=76\ volts$

Step-by-step explanation:

$Given\ V=4√(P)\n\nwhere\ V\ is\ voltage\ and\ P\ is\ Power.$

$Here\ power\ is\ given\n\nP=361\ watts\n\nSubstitute\ P\ in\ the\ given\ equation\n\nV=4√(P)\n\nV=4√(361)\n\nV=4√(19* 19)\n\nV=4* 19\n\nV=76\ volts$

STEP 1Choose at least 4 of the following constructions to use on your Wrapping Paper Design:
• A bisected angle
• A perpendicular line drawn from a point not on a line to a line
• A perpendicular line drawn through a given point on a given line
• A quadrilateral with at least one pair of parallel lines
• A segment bisected by a perpendicular line, ray, or segment
• An equilateral triangle
• Two congruent triangles
• Two congruent segments
• Two parallel lines, one of which is drawn through a given point
Perform these constructions on a sheet of paper leaving all marks used in the construction.
STEP 2
Write down the instructions for the 4 chosen constructions, in your own words. Give these instructions to another person to recreate the constructions. Adjust your instructions as needed to make sure they are clear and precise. (Take notes, this will be included in your reflection summary).
STEP 3
Combine your constructions to make a pattern or design for your Wrapping Paper. You will do this on a standard sheet of paper. Be creative, but make sure to include all 4 of your constructions. Make sure to number your constructions and create a key describing each element.
STEP 4
Write a paragraph reflecting on any difficulties you encountered creating your design, the key, or writing your construction instructions.

what do u need to do exactly

Final answer:

This high school mathematics assignment involves practicing geometrical constructions, creating a wrapping paper design using the constructs, documenting the process, and writing a reflection summary about it.

Explanation:

This activity seems to be about practicing geometrical constructions and applying these skills in a creative context, most likely as a part of a geometry class. It involves choosing four different geometrical constructs, drawing them, recording the instructions on creating these constructs, using these constructs to make a wrapping paper design, and then reflecting on the process.

Step 1: Choose the four constructs like a bisected angle, a quadrilateral with at least one pair of parallel lines, an equilateral triangle, and two parallel lines, one of which is drawn through a given point.

Step 2: Carefully write down the step by step instructions for the chosen geometrical constructs. These instructions must be easy to understand and follow.

Step 3: Combine all the selected constructs into a creative design for wrapping paper. It is essential to accurately depict the constructs in the design and label each element using a key.

Step 4: Once the design is complete, write a reflection summary about the process. This reflection may include any difficulties encountered in creating the design or writing the construction instructions.
