George went to The Clothes Shack and bought 4 pairs of jeans for $30, 2 pairs of T-shirts for $15, and 3 pairs of shorts for $20. Write an expression that can be used to find the total amount that George spent. How much did George spend?

Answer:Answer:

81 miles

Step-by-step explanation:

From the question 7/10 of the trip has been said to be downhill. It therefore means that 3/10 is not downhill.

Miles = 270

Downhill = 7/10

Not downhill = 3/10

Now we have To calculate Miles that are not downhill (uphill)

But first I calculated for the number of downhill miles

270x7/10

Downhill = 189 miles

To get the number of not downhill miles

I subtracted 189 from the total number of miles on the question.

270 - 189

= 81 Miles.

Therefore 81 Miles of the trip are not downhill.

Step-by-step explanation:

"Determine the number and type of roots for the equation using one of the given roots. Then find each root. (inclusive of imaginary roots.)"

Given one of the roots, we can use either long division or grouping to factor each cubic equation into a binomial and a quadratic.  I'll use grouping.

Then, we can either factor or use the quadratic equation to find the remaining two roots.

1. x³ − 7x + 6 = 0; 1

x³ − x − 6x + 6 = 0

x (x² − 1) − 6 (x − 1) = 0

x (x + 1) (x − 1) − 6 (x − 1) = 0

(x² + x − 6) (x − 1) = 0

(x + 3) (x − 2) (x − 1) = 0

The remaining two roots are both real: -3 and +2.

2. x³ − 3x² + 25x + 29 = 0; -1

x³ − 3x² + 25x + 29 = 0

x³ − 3x² − 4x + 29x + 29 = 0

x (x² − 3x − 4) + 29 (x + 1) = 0

x (x − 4) (x + 1) + 29 (x + 1) = 0

(x² − 4x + 29) (x + 1) = 0

x = [ 4 ± √(16 − 4(1)(29)) ] / 2

x = (4 ± 10i) / 2

x = 2 ± 5i

The remaining two roots are both imaginary: 2 − 5i and 2 + 5i.

3. x³ − 4x² − 3x + 18 = 0; 3

x³ − 4x² − 3x + 18 = 0

x³ − 4x² + 3x − 6x + 18 = 0

x (x² − 4x + 3) − 6 (x − 3) = 0

x (x − 1)(x − 3) − 6 (x − 3) = 0

(x² − x − 6) (x − 3) = 0

(x − 3) (x + 2) (x − 3) = 0

The remaining two roots are both real: -2 and +3.

"Find all the zeros of the function"

For quadratics, we can factor using either AC method or quadratic formula.  For cubics, we can use the rational root test to check for possible rational roots.

4. f(x) = x² + 4x − 12

0 = (x + 6) (x − 2)

x = -6 or +2

5. f(x) = x³ − 3x² + x + 5

Possible rational roots: ±1/1, ±5/1

f(-1) = 0

-1 is a root, so use grouping to factor.

f(x) = x³ − 3x² − 4x + 5x + 5

f(x) = x (x² − 3x − 4) + 5 (x + 1)

f(x) = x (x − 4) (x + 1) + 5 (x + 1)

f(x) = (x² − 4x + 5) (x + 1)

x = [ 4 ± √(16 − 4(1)(5)) ] / 2

x = (4 ± 2i) / 2

x = 2 ± i

The three roots are x = -1, x = 2 − i, x = 2 + i.

6. f(x) = x³ − 4x² − 7x + 10

Possible rational roots: ±1/1, ±2/1, ±5/1, ±10/1

f(-2) = 0, f(1) = 0, f(5) = 0

The three roots are x = -2, x = 1, and x = 5.

"Write the simplest polynomial function with integral coefficients that has the given zeros."

A polynomial with roots a, b, c, is f(x) = (x − a) (x − b) (x − c).  Remember that imaginary roots come in conjugate pairs.

7. -5, -1, 3, 7

f(x) = (x + 5) (x + 1) (x − 3) (x − 7)

f(x) = (x² + 6x + 5) (x² − 10x + 21)

f(x) = x² (x² − 10x + 21) + 6x (x² − 10x + 21) + 5 (x² − 10x + 21)

f(x) = x⁴ − 10x³ + 21x² + 6x³ − 60x² + 126x + 5x² − 50x + 105

f(x) = x⁴ − 4x³ − 34x² + 76x − 50x + 105

8. 4, 2+3i

If 2 + 3i is a root, then 2 − 3i is also a root.

f(x) = (x − 4) (x − (2+3i)) (x − (2−3i))

f(x) = (x − 4) (x² − (2+3i) x − (2−3i) x + (2+3i)(2−3i))

f(x) = (x − 4) (x² − (2+3i+2−3i) x + (4+9))

f(x) = (x − 4) (x² − 4x + 13)

f(x) = x (x² − 4x + 13) − 4 (x² − 4x + 13)

f(x) = x³ − 4x² + 13x − 4x² + 16x − 52

f(x) = x³ − 8x² + 29x − 52

Answer:

y = 3

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

We know that a horizontal line has a slope of zero:

Slope m = 0

y = 0x + b

y = b

Since we are trying to find a line that fits with (-1, 3), we look solely at the y-value.

y = 3

We want to find the equation of a horizontal line such that it passes through a given point.

The answer is: y = 3

We know that the general form of a horizontal line is:

y = a

Where a is a real number.

Now, we also want that our line passes through the point (-1, 3).

Notice that the y-value of the point is 3, and in a horizontal line we can have only one value of y, so the horizontal line must be:

y = 3

The graph of the line and the point can be seen below

Answer:

Infinite Amount of Solutions

Step-by-step explanation:

Step 1: Write out equation

2a + 6 = 2a + 5 + 1

Step 2: Combine like terms

2a + 6 = 2a + 6

Here we see that we have the same slope and same y-intercept or the same equation. When this happens, our solution set is infinite amount of solutions, as any value a can be plugged in and would be true.

Part A

1 hour = 60 minutes

0.5 hours = 30 minutes (multiply both sides by 0.5)

11.5 hours = 11 hours + 0.5 hours

11.5 hours = 11 hours + 30 minutes

11.5 hours = 11 hours, 30 minutes is the answer

========================================

Part B

20% = 20/100 = 0.20

The lion sleeps 20% more than the cat, which means the lion sleeps 0.20*11.5 = 2.3 hours more

This leads to 11.5 + 2.3 = 13.8 hours being the total time the lion sleeps

1 hour = 60 minutes

0.8 hours = 48 minutes (multiply both sides by 0.8)

13.8 hours = 13 hours + 0.8 hours

13.8 hours = 13 hours + 48 minutes

13.8 hours = 13 hours, 48 minutes is the amount of time the lion sleeps

Answer:  B. g(x) = –4(x – 3)2

Step-by-step explanation: To apply the changes to the equation of a vertical stretch of 4 and a translation of 3 units to the right, as well as the correct answer would be choice B.

The reason for this is when you apply a vertical stretch, because it changes the y-values (which causes it to vertically stretch or appear skinnier when graphed), you would multiply 4 to f(x) which would look like 4x^2.

Then, since you have a reflection over the x-axis, you must multiply a -1 to f(x) to reflect it over the x-axis which would result in -4x^2.

Finally, it also asks to shift the graph right 3 which by moving it right, you change the x values meaning you will perform f(x-3) to achieve this (subtract the value from x when you move right, and add the value to x when you move left).

Complete Question  

Find the average value of the function over the given interval. (Round your answer to three decimal places.) f(x) = 12e^x, [−6, 6] Find all values of x in the interval for which the function equals its average value. (Enter your answers as a comma-separated list. Round your answers to three decimal places.)

Answer:

The  average is  

  [tex]AV  =  403[/tex]

The value of  x is

   [tex]x =  4[/tex]

Step-by-step explanation:

From the question we are told that

  The equation is  [tex]f(t) =  12e^x[/tex]

  The  points consider is  [-6 , 6]

Generally the average value of the function over the given interval is mathematically represented as

          [tex]AV  =  \frac{1}{z-w} \int\limits^ z_w {f(x)} \, dx[/tex]

          [tex]AV  =  \frac{1}{ 6 - (-6)}  \int\limits^{6}_{-6} { 12e^x} \, dx[/tex]

          [tex]AV  =  \frac{1}{12 } e^x| \left 6} \atop {-6}} \right.[/tex]

          [tex]AV  = e^6 -e^{-6}[/tex]

          [tex]AV  =  403[/tex]

Generally when the function equal the average we have that

        [tex]f(x) =  12e^{x} =  403[/tex]

        [tex]e^{x} =  34[/tex]

          [tex]x =  ln(34)[/tex]

        [tex]x =  4[/tex]

f(x) = 3x – 2, g(x) = 7 – x2.

3f(1) - 49(-2)

Substitute the given value into the function and evaluate.

101

The value of 3f(1) - 49(-2) for the given function f(x) = 3x – 2 will be 101.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the function,

f(x) = 3x – 2

Now,

f(1) = 3(1) - 2 = 1

So,

3f(1) - 49(-2) = 3×1 - 49(-2)

⇒ 3 + 98 = 101

Hence "The value of 3f(1) - 49(-2) for the given function f(x) = 3x – 2 will be 101".

2/5 and 3/10

now, we have,

to compare you need to make them common denominator,

and that could be10.

to make both denominators equal to ten just multiply the top and bottom of 2/5 by 2.

i.e. 2*2/5*2

=4/10

this will turn it into 4/10.

now, we get,

4/10 is greater than 3/10

Hence, 2/5> 3/10 , 2/5 is greater than 3/10.

Answer:

Step-by-step explanation:

Given the ratio of fiction to nonfiction books in a classroom library is 2 to 3, then the total ratio of both books will be 2+3 = 5. If there are 24 books non fiction books in the library, to get the amount of fictionbooks that are there we will follow the following steps.

First we will calculate the total number of books in the shelf;

3/5 * Total number of books = total non fiction books

3/5 * Total number of books = 24

3*Total number of books = 5*24

3*Total number of books = 120

Total number of books = 120/3

Total number of books = 40

Therefore there are 40 total of books on the shelf.

Total number of fiction books = 2/5 * 40

Total number of fiction books = 2* 8

Total number of fiction books = 16 books

Hence there are 16 fiction books on the shelf.
