Create a 5th degree trinomial that has a constant term of 3.

Answers

Answer:

[tex]2x^5+3x^2+3[/tex] is a trinomial having with:

three terms degree 5 and The constant term '3'

Step-by-step explanation:

Considering the trinomial

[tex]2x^5+3x^2+3[/tex]

Any polynomial with 3 terms is a trinomial, so it is a trinomial.

It is clear that '5' is the highest power of the 'x' variable. so, the polynomial has a degree of 5.

'3' is the constant term. The reason is that any term with no variable is called a 'constant' term. So, '3' is the constant term.

Therefore, [tex]2x^5+3x^2+3[/tex] is a trinomial having with:

three terms degree 5 and The constant term '3'

Cardi B is buying a condo built within

floors, where f is the number of floors.

How tall, in feet, would her condo be in the skyscraper if she was on the 26th floor?
PLEASE HELP... 25 points

Answers

Answer:

13f is equation

which is floors times height

Step-by-step explanation:

26*13=338

338 feet tall

Brainliest appreciated!

Answer:

(H)=13f and  the height is 338ft

Step-by-step explanation:

height of skyscraper=h

f=floors

height per floor is 13ft...

(H)=13f

(H)=13*f, if f is 26, then to find height multiply 13 by 26

doing this you get 13*26=338ft

A population of values has a normal distribution with μ = 245.3 and σ = 96 . You intend to draw a random sample of size n = 50 . Find the probability that a single randomly selected value is greater than 246.7. P(X > 246.7) = 0.0146 Incorrect Find the probability that a sample of size n = 50 is randomly selected with a mean greater than 246.7. P(M > 246.7) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

Answers

Answer:

0.4589

Step-by-step explanation:

We solve using z score formula

The z score formula for a random number of samples is:

z = (x-μ)/σ/√n, where x is the raw score, μ is the population mean, and σ is the population standard deviation

Hence:

z = 246.7 - 245.3/96/√50

z = 0.10312

Probability value from Z-Table:

P(x<246.7) = 0.54107

P(x>246.7) = 1 - P(x<246.7) = 0.45893

Approximately to 4 decimal places = 0.4589

The probability that a single randomly selected value is greater than 246.7 is 0.4589

Deion divided 1/2 of a liter of plant fertilizer evenly among some smaller bottles. He put 1/8 of a liter into each bottle. How many smaller bottles did Deion fill?

Answers

Answer:

4 bottles

Step-by-step explanation:

Given

[tex]Fertilizer = \frac{1}{2}L[/tex]

[tex]Bottles = \frac{1}{8}L[/tex]

Required

Determine the number of bottles

Represent the number of bottles with N

This implies that N bottles of [tex]\frac{1}{8}L[/tex] fit into [tex]\frac{1}{2}L[/tex] of fertilizer. The relationship between them is:

[tex]Fertilizer = Bottles * N[/tex]

[tex]\frac{1}{2}L = \frac{1}{8}L* N[/tex]

[tex]\frac{1}{2} = \frac{1}{8}* N[/tex]

Multiply through by 8

[tex]8 * \frac{1}{2} = 8 * \frac{1}{8}* N[/tex]

[tex]4 = 1* N[/tex]

[tex]4 = N[/tex]

[tex]N = 4[/tex]

Hence, there are  N = 4

Tre has to pay $180 to book the recording studio plus $30 per hour of recording time. The function c(h)=30h+180 relates the total cost, c(h) of the recording session (in dollars) to the number of hours, (h) needed to record the tracks.

Answers

Answer:

1. $3302. 11.5 hours

Step-by-step explanation:

Continuation of the question:

1. Find c (5) and interpret your solution in the context of the problem 2. Find the value of h when c() = 525 and interpret your solution in the context of the problem

Solution

c(h) = 30h + 180

1 ...............................................

c(5) = 30*5 + 180 = $330

2 ...............................................

525 = 30h + 18030h = 525 - 18030h = 345h = 345/30 h = 11.5 hours

Answers

Answer:

Slope is 100

y-intercept is 85

Step-by-step explanation:

The equation of a straight line can be modeled according to the function;

y = mx + c

where m is the slope and c is the y-intercept

comparing what we have ;

y = 100x + 85 with the standard form ;

Slope will be 100 and y-intercept is 85

5. Jordan works at the car wash a few hours a week and works mowing lawns for extra money.
Because of his schoolwork, he can't work more than 10 hours per week. Write a rule to see possible
solutions for his work schedule. Let x represent hours at the car wash, and y represent the hours
mowing lawns.

Answers

Answer:

The rule is

x + y ≤ 10

Step-by-step explanation:

Here, we want to write a rule that can help get solutions for the individual work hours

The number of hours for car wash is x while the number of hours for mowing lawns is y

Since he cannot work more than 10 hours, he can still work less than 10 hours

What we just have is that the addition of both working hours must not be over 10

So the rule to write is;

x + y ≤ 10

When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120. Find the hourly rate of pay for Ben and Judy.

Answers

Answer:

They each earn 15 an hour

Step-by-step explanation:

Answer:

They both make $15

Step-by-step explanation:

In the first scenario Judy worked for 4 hours, (4)*(15)=60 plus Ben, (1)*(15)=15 which equals 75. In the second scenario, Judy works 2 hours so (2)*(15)=30 and Ben works 6, (6)*(15)= 90 which is 120.

Answer:

  64r -48r -144

Step-by-step explanation:

The January cost expression is ...

  62p -48p -144 -432 = profit

The cost is identified as having 3 components, so the profit will have 4 components:

  (selling price)×p - ((cost per unit)×p +(fixed monthly cost)) -(first month startup cost) = profit

Comparing this to the given equation, we identify the components as ...

  selling price = 62

  cost per unit = 48

  fixed monthly cost = 144

  first month startup cost = 432

We note that 432 = 3×144, so is consistent with the description of startup costs.

Increasing the selling price by $2 will raise it from 62 to 64. In February, the initial month startup cost disappears, so the profit equation becomes ...

  (selling price)×r - ((cost per unit)×r +(fixed monthly cost)) = profit

  64r -48r -144 = profit
