What is a polynomial?

A polynomial function is a mathematical expression that is consists of different types of variables such as non-zero coefficients, positive exponents, and constants.

Types of polynomials

1. Linear polynomial function: it is made up of a single variable raised to the power of 1. An example is y + 2

2.  Quadratic polynomial function - it has a single variable and it is raised to the power of 2. An example is x² + 10x + 25

3. Cubic polynomial function: it has a single variable raised to the power of 3. An example is 5y³ + y²

4. Binominal function: this is a function that contains only two terms. An example is t³ - 400

2²ˣ = 6ˣ⁻³
How would I convert this to logarithmic form, then solve in log M / log N format?

Answers

6 = 2 • 3, so

6ˣ⁻³ = 2ˣ⁻³ • 3ˣ⁻³

Then in

2²ˣ = 6ˣ⁻³

we would have

2²ˣ = 2ˣ⁻³ • 3ˣ⁻³

2²ˣ / 2ˣ⁻³ = 3ˣ⁻³

2²ˣ⁻ˣ⁺³ = 3ˣ⁻³

2ˣ⁺³ = 3ˣ⁻³

Now take the logarithm of both sides. The base you choose doesn't matter.

log(2ˣ⁺³) = log(3ˣ⁻³)

Recall that log(aⁿ) = n log(a), so that the equation reduces to

(x + 3) log(2) = (x - 3) log(3)

Solve for x :

log(2) x + 3 log(2) = log(3) x - 3 log(3)

(log(2) - log(3)) x = - 3 log(2) - 3 log(3)

Recall that log(a) - log(b) = log(a/b), and log(a) + log(b) = log(ab), so that

log(2) - log(3) = log(2/3)

- 3 log(2) - 3 log(3) = - 3 (log(2) + log(3)) = - 3 log(6)

So, we get

log(2/3) x = - 3 log(6)

x = -3 log(6) / log(2/3)

As I mentioned, the base of the logarithm doesn't matter, x will always have the same value of about 13.257.

1. If energy is the ability to cause change, then
what evidence is there that energy is produced in
the interaction between the wind and the blades of
the wind turbine?

Answers

Answer:

We get electricity, that's all the evidence

Step-by-step explanation:

Have a GOOD DAY

We will use the idea that "energy is the ability to cause change" to study the interaction between wind and the blades of a turbine.

This is actually really trivial, if we look at the blades and they are stopped, then we can conclude that there is no wind, thus there is no energy. (By the Newton's laws, we know that there must be a force to change the movement of something).

Now if wind comes, the wind will cause a force on the blades making them rotate.

So a form of energy comes, mechanical energy, and we can see how it produces changes.

Then by the rotation of the blades, there are dynamos that can be used to charge and store energy, this is (roughly) how a wind turbine works.

So to answer this all you need to do is set the equations equal to each other. You set 0.75x=10+0.50x, then you can plug in any of the values. So either 6,8,30, or 40. And that’ll give you your answer, to help u out the answer is 40. They both end up equaling 30.

Ashley recently opened a store that uses only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes one person \dfrac{2}{3} 3 2 ​ start fraction, 2, divided by, 3, end fraction of a minute to prepare one bag. How many hours will it take Ashley and 4 of her friends to prepare 1575 bags of samples?

Answers

Answer:

5.3 hours

Step-by-step explanation:

Ashley recently opened a store that uses only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes Ashley 2/3 of a minute to prepare one bag. It takes each of her friends 75% longer to prepare a bag. How many hours will it take Ashley and 4 of her friends to prepare 1575 bags of samples?

Time it takes 1 person to preprate one bag = 2/3 min

Time it takes each friend of Ashley: 75% more than 2/3 min

75% × 2/3 minutes

=75/100 × 2/3 minutes

= 0.75 × 2/3

= 0.5 min

= 1/2 minutes

Friends = 2/3 min + 1/2 min = 7/6 min per friend

Time it takes Ashley and the 4 friends working along to prepare one bag:

Ashley's time per bag = 1 bag / (2/3) min

= 3/2 bag/min

Ashley's friends time per bag = 1 bag / (7/6) min

= 6/7 bag/min

Total = 3/2 bag/min + 4 × 6/7 bag/min

= (3/2 +24/7)

= 69/14 bag/min

Time it takes to prepare 1575 bags of samples = number of bags / number of bags per min

= 1,575 bags / (69/14) bags/min

= 319.56 min

Convert to hours:

356.56 min / 60 min per hour

= 5.3 hours

The force of gravity on the surface of jupiter is about 2.5 times as strong as that on earth. ON jupiter, the height of a ball dropped from a 100-meter tower is given by the function h(t) = -25t +100 meters at t seconds. How many seconds will it take for the ball to hit the ground?

Answers

Answer:

4 seconds

Step-by-step explanation:

Given

[tex]h(t) = -25t + 100[/tex]

Required

Determine what time it hits the ground

When the ball is on the ground, the height is at 0

i.e.

[tex]h(t) = 0[/tex]

Substitute 0 for h(t) in [tex]h(t) = -25t + 100[/tex]

[tex]0 = -25t + 100[/tex]

Collect Like Terms

[tex]25t = 100[/tex]

Solve for t

[tex]t = 100/25[/tex]

[tex]t = 4[/tex]

Hence, the ball will hit the ground in 4 seconds

The gravity coaster travels 340 meters in 10 seconds. The hurricane coater travels 190 meters in 5 seconds. Both coaters travels at a constant. Mario wants to ride the faster roller coaster. How fast does the gravity coaster travel? Find the unit rate.

Answers

Answer:

Mario would like to ride Hurricane coaster.

Gravity coaster travels at a unit rate of 34 m/s.

Step-by-step explanation:

Distance traveled by Gravity coaster = 340 meters

Time taken by Gravity coaster = 10 seconds

Distance traveled by Hurricane coaster = 190 meters

Time taken by Hurricane coaster = 5 seconds

Unit rate is nothing but the distance traveled by each coaster in unit time.

To find the unit rate, we can use the following formula:

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Unit rate or speed of Gravity coaster = [tex]\frac{340\ m}{10\ s} = 34\ m/s[/tex]

Unit rate or speed of Hurricane coaster = [tex]\frac{190\ m}{5\ s} = 38\ m/s[/tex]

So, the faster coaster is the Hurricane coaster.

Mario would like to ride Hurricane coaster.

Gravity coaster travels at 34 m/s.

Find the slope of the line drawn on the graph. If your answer is a fraction, leave in simplified fraction form.

Answers

given that each unit is equal to 1 , which is assumed since they aren’t marked , the answer would be

reason — slope = rise over run , so you would move up 2 and over 5 units to get the slope of 2/5

Answer: The slope would be 2/5.

Step-by-step explanation: To find the slope, it's rise divided by run. The 2 points on this graph are (-2,-1) and (3,1). So basically,  change in y value, divided by the change in x value.

eight more than three times a number is 32

Answers

Answer:

3 times 8 = 24  + 8 = 32

Step-by-step explanation:

Answer:

The number is 8

Step-by-step explanation:

3x + 8 = 32

3x = 24

x = 8

________

A number can be denoted as x. 3 times a number is 3 of that number, and 8 more than a number is that number plus 8. This relationship can be given by:

x + x + x + 8 = 32

(x + x + x) + 8 = 32

3x + 8 = 32

3x + 8 - 8 = 32 - 8

3x = 24

3x/3 = 24/3

x = 8
