Answer 1

Answer:

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

f-(100/4+37)=0

Step by step solution :

STEP

Simplify ——

Equation at the end of step

f - (25 + 37) = 0

STEP

Equation at the end of step 2

f - 62 = 0

STEP

Solving a Single Variable Equation:

3.1 Solve : f-62 = 0

Add 62 to both sides of the equation :

f = 62

One solution was found :

f = 62

Sketch one cycle of the sine curve. y = -3 sin 4theta

Answers

Answer:

Step-by-step explanation:

We have been given a function:

$y=-3sin4\theta$

We will compare it with the genral equation which is:

$y=asin bx+c$

Where, a is amplitude and period of function is $(2\pi)/(b)$

In given equation a is -3 and b is 4

So, period of the given equation is:

$(2\pi)/(4)=(\pi)/(2)$

Yo can look at the graph in the attachment.

The a is the amplitude and the period of the function is $(2\pi )/(b)$

We have been given a function

$y = -3 sin 4 \theta$

What is the general form of sin wave?

$y=asinbx+c$

We will compare it with the general equation which is

Where a is amplitude and period of the function is $(2\pi )/(b)$

In the given equation a is -3 and b is 4

So, the period of the given equation is:

$(2\pi )/(4) =(\pi )/(2)$

You can look at the graph.

There are 10 vehicles in a parking lot: 3 SUVs and 7 trucks. What is the probability that any 7 randomly chosen parking spots have 2 SUVs and 5 trucks OR 3 SUVs and 4 trucks?

Answers

We have to calculate the probability that any randomly choosen parking spots have 2 SUVs and 5 trucks or 3 SUVs and 4 trucks. We will use the formula with combinations: P = ( 3C2 * 7C5 ) / ( 10C7) + ( 3C3 * 4C7) / ( 10C7). For example: 10C7 = 10! / 7!*(10-7)! = 10!/7!*3!= 10*9*8/3*2*1 = 120, etc. P = ( 3 * 21 ) / 120 + ( 1 * 35 ) / 120 = 63 / 120 + 35 / 120 = 98 / 120 = 0.8166. Answer: The probability is 0.8166 or 81.66%.

YOUR ASSIGNMENT: Factory Lighting ProblemIn this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher.

You are deciding whether to light a new factory using bulb A, bulb B, or bulb C.

Which bulb would be better to use on the factory floor?
Which bulb would be better to use in the break room?
To answer these questions, you will compare the energy usage of the three bulbs. The amount of energy the lights use is measured in units of kilowatt-hours. A kilowatt-hour is the amount of energy needed to provide 1000 watts of power for 1 hour.

1. Circle the two bulbs you picked.
incandescent
Halogen
Fluorescent

2.

3. Practice: Summarizing (3 points)
Fill in the blanks.

The energy usage of a light bulb is a function. The input for the function is _________, measured in hours.

The output of the function is energy usage, measured in ____________.

Identify the functional relationship between the variables. _________________ is a function of _________________.

The graph of the function will show energy usage on the _____________ axis and time on the _______________ axis.
4. Practice: Organizing Information (2 points)
Use the data given to complete the table for your first bulb.
DATA TABLE A
Time (hours) x Energy (kWh) y Point (time, energy) (x, y)

The workers leave the lights on in the break room for stretches of about 3 hours. Which light bulb would light this room using the least amount of energy?

10. Practice: Summarizing (1 point)
The lights in the main room of the factory stay on for stretches of 9 hours. Which kind of light bulb would light this room with the least amount of energy?

Answers

Answer:

To determine which bulb would be better to use on the factory floor and in the break room, we need to compare the energy usage of the three bulbs: incandescent, halogen, and fluorescent.

1. Based on energy efficiency, we would circle the two bulbs that are more energy-efficient: halogen and fluorescent.

3. Summarizing:

- The energy usage of a light bulb is a function. The input for the function is time, measured in hours.

- The output of the function is energy usage, measured in kilowatt-hours (kWh).

- Time is a function of energy usage.

5. Organizing Information: DATA TABLE B

Time (hours) x Energy (kWh) y Point (time, energy) (x, y)

6. Organizing Information:

- Graph 1: Label the axes with "Time (hours)" and "Energy (kWh)". Plot the points from Table A and connect them with a line.

- Graph 2: Label the axes with "Time (hours)" and "Energy (kWh)". Plot the points from Table B and connect them with a line.

7. Summarizing:

- Graph 1 (First bulb) classification: Unknown, as the points are not provided.

- Graph 2 (Second bulb) classification: Unknown, as the points are not provided.

8. Summarizing:

- First bulb: When 3 hours is the input, the output (energy usage) is unknown. When 10 hours is the input, the output (energy usage) is unknown.

- Second bulb: When 3 hours is the input, the output (energy usage) is unknown. When 10 hours is the input, the output (energy usage) is unknown.

9. Summarizing:

- To determine which light bulb would consume the least amount of energy in the break room for stretches of about 3 hours, we need the data or information on energy usage for each bulb. Without that information, it's not possible to make a definitive conclusion.

10. Summarizing:

- Similarly, to determine which light bulb would consume the least amount of energy in the main room of the factory for stretches of 9 hours, we need the data or information on energy usage for each bulb. Without that information, it's not possible to make a definitive conclusion.

In summary, without the energy usage data for each bulb, we cannot determine which bulb would be better to use on the factory floor or in the break room, or which bulb would consume the least amount of energy for specific time durations.
