Answer:

If I calculated correctly, the tangent line is horizontal where x ≈ -5.3 + 9.3i, and -5.3 - 9.3i

I'm somewhat concerned at having gotten complex numbers, and strongly recommend going through the steps to see if I missed anything.  I checked it myself and don't see any errors.

Step-by-step explanation:

You can do this by taking the derivative of the function and solving for zero:

f(x) = 2x³ + 32x² + 220x + 11

f'(x) = 6x² + 64x + 220

f'(x) = 2(3x² + 32x + 110)

We can't factor that further, so let's do it the long way, starting by letting f'(x) equal zero:

0 = 2(3x² + 32x + 110)

0 = 3x² + 32x + 110

0 = 9x² + 96x + 990

0 = 9x² + 96x + 256 + 734

0 = (3x + 16)² + 734

(3x + 16)² = -734

3x + 16 = ± i√734

3x = -16 ± i√734

x = (-16 ± i√734) / 3

x ≈ (-16 + 27.9i) / 3, and  (16 - 27.9i) / 3

x ≈ -5.3 + 9.3i, and -5.3 - 9.3i

I'm always wary when I end up with complex numbers.  I'd suggest double checking everything here, but I'm fairly certain I did everything correctly.

20<5n<25

4<n<5

Inequalities help us to compare two unequal expressions.The compound inequality that shows the range of numbers that Dewayne might be thinking of is 8<(5n-7)<13.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The given clue by Dewayne can be written in the form of inequality as shown below. Therefore, we can write,

Hence, the compound inequality that shows the range of numbers that Dewayne might be thinking of is 8<(5n-7)<13.

Step-by-step explanation:

The terms are what are separated by + or - signs. They generally consist of a product of numbers and variables, or they may be a number or variable by itself.

Additional comment

When you're learning about terms, you are generally concerned with polynomials. For that purpose, a "term" is as described above.

More generally, any designated expression or part of an expression can be referred to as a "term". For example, we might refer to √(b²-4ac) in the expression ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

as "the radical term", or we might refer to 2a as "the denominator term". In this expression, the term (b²-4ac) is given the name "discriminant".

Answer:

Angle 1 is 69°. Angle 2 is 111°

Explanation:

Answer:

top one is 48 cm, bottom one is 17.5in.

Step-by-step explanation:

From what I understand, these shapes are increasing in size, so they will increase at a certain number. Our top one is rotated, but the 12cm is equivalent to the 3cm from the previous rectangle, thus making it greater by 4 times. To find x, we multiply 12cm by 4 to get 48cm. Same concept for the shapes on the bottom. Our 56in is equivalent to 8in, making it 7 times larger. Now, we multiply 2.5 by 7 to get 17.5in.

Answer:

B. -6

Step-by-step explanation:

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

b = 4, f(b) = -15

a = 2, f(a) = -3

Plug in the values

[tex] \frac{-15 - (-3)}{4 - 2} [/tex]

[tex] = \frac{-12}{2} = -6 [/tex]

The average rate of change of the given quadratic function in the given interval is -6.

On the graph, we can see that:

f(4) = -15

f(2) = -3

Then the average rate of change on that interval will be:

[tex]y = \frac{f(4) - f(2)}{4 - 2} = \frac{-15 + 3}{2} = -6[/tex]

Then we conclude that the average rate of change of the given quadratic function on the given interval is -6.

Answer:

x = 11.75

Step-by-step explanation:

hope this was helpful!

Answer:

11.75

Step-by-step explanation:

Answer:

Angle 1 =  108°

Angle 2 =  72°

Angle 3 =  120°

Angle 4 =  96°

Angle 5 =  144°

Step-by-step explanation:

We need to find the measures of the interior  angles in a pentagon if the measure  of each consecutive angle is in the  ratio 9:6:10:8:12.

Let x be the common ratio

So, we can write:

Angle 1 = 9x

Angle 2 = 6x

Angle 3 = 10x

Angle 4 = 8x

Angle 5 = 12x

We know that the sum of all angles of pentagon = 540

So, adding all angles and equal them to 540, we can find value of x

[tex]9x+6x+10x+8x+12x=540\\45x=540\\x=\frac{540}{45}\\x=12[/tex]

So, we get the value of x: x=12

Now, calculating the angles by putting x=12:

Angle 1 = 9x = 9(12) = 108°

Angle 2 = 6x = 6(12) = 72°

Angle 3 = 10x = 10(12) = 120°

Angle 4 = 8x = 8(12) = 96°

Angle 5 = 12x= 12(12) = 144°

Answer:

$1.77

Step-by-step explanation:

$1 plus 75 cents plus 2 cents

The total amount of money that Rachel has is $1.77.

The study and use of numbers, their relationships, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The word "arithmetic" (which derives from the Greek word "arithmos," "number") is frequently used to refer to the basic ideas in measuring, calculation, and number theory (specifically, the operations of addition, subtraction, multiplication, division, raising to powers, and root extraction).

As per the given data:

We are given the amount of dollar bills, quarters and pennies Rachel has.

Dollar bills = 1

Quarters = 3

Pennies = 2

1 Dollar bill = $1

1 Quarter = $0.25

1 Penny = $0.01

Total money that Rachel has

= 1 × (Dollar bill) + 3 × (Quarters) + 2 × (Pennies)

= 1 × ($1) + 3 × ($0.25) + 2 × ($0.01)

= 1 + 0.75 + 0.02

= $1.77

The total amount of money that Rachel has is $1.77.

Hence, The total amount of money that Rachel has is $1.77.

1.What is the population of interest in this study?

Bloomberg business week NorthAmerica Subscribers

2. Quantitative

Annual income is quantitative because it is numeric, that is repress red by numbers which can be used to perform sensible numerical computation such as additions, mean, multiplication and so on.

3.Qualitative

No ; ownership of an American express card is a Qualitative variable as it will take responses as (yes or no), even when represented or coded as numbers, it will make no numerical sense to peform mathematical calculations with it.

4.

No ; time series data has to do with data collected with respect to a particular month, year or seasonal data.

Answer:

-1

Step-by-step explanation:

So to solve this, it tells you that (3, -2) is a solution so you can substitute x = 3 and y = -2 into the equation which would look like this:

[tex]3*3-p*-2-7 = 0[/tex]

Then, you solve the equation for p:

first, simplify the left side

[tex]9 +2p-7=0\\2+2p=0[/tex]

subtract 2 from both sides

[tex]2p=-2[/tex]

divide both sides by 2

[tex]p=-1[/tex]

Now, you have p = -1!
