Answer:

  p(x) = x^4 -8x^3 +16x^2 -8x +15

Step-by-step explanation:

Assuming you want real coefficients, the imaginary root means its conjugate is also a root. In factored form, the polynomial is ...

  p(x) = (x -3)(x -5)(x -i)(x +i) = (x^2 -8x +15)(x^2 +1)

  p(x) = x^4 -8x^3 +16x^2 -8x +15

Answer:

C

Step-by-step explanation:

It's y=-4/1-21

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line is y = (-1/2)x + 7

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Let the equation of the line is y = m(1)x + c

The line is perpendicular to 2x - 8y = 3

The means,

2x - 8y = 3

-8y = 3 - 2x

y = -(3 - 2x)

y = -3 + 2x

y = 2x - 3

This is in the form of y = m(2)x + c

m(2) = 2 and c = -3

Now,

The line y = m(1) + c is perpendicular to y = m(2) + c

So,

m(1) x m(2) = -1

m(1) = -1/2

Now,

The line contains (-8, 11) = (x, y).

This means,

y = m(1)x + c

11 = (-1/2) x -8 + c

11 = 4 + c

c = 11 - 4

c = 7

Now,

The equation of the line is y = (-1/2)x + 7

Thus,

The equation of the line is y = (-1/2)x + 7

Answer:

Hope this helped ;)

No.

When you divide by a positive value you do not flip the inequality, only when dividing by a negative value.

2x < -6

To solve for c you divide both sides by 2, which is a positive value so the inequality stays the same:

X < -6/2

X < -3

Answer: fourth option (3² × 5)

Step-by-step explanation: The prime factorization of 135 is (3² × 5) because:

3 x 3 x 3 = 27

27 x 5 = 135

The answer to the question is (3² × 5).

Answer:

3^3 × 5 [Fourth option, bottom one]

Step-by-step explanation:

First, 3^2 × 5^2 cannot be correct because although 3, and 5 are prime numbers 3^2 × 5^2 ≠ 135 as 3^2 × 5^2 = 225.

Second, 3 × 5 × 9 can't be right because although 3 × 5 × 9 = 135, 9 is not a prime number.

Third, 3 × 5^3 is not correct because although 3 and 5 are prime numbers, 3 × 5^3 ≠ 135 as 3 × 5^3 = 375.

The last question must be correct because it is the only remaining choice answer. Plus 3 and 5 are both prime numbers, and 3^3 × 5 = 135, 3^3 × 5 = 3 × 3 × 3 × 5 = 27 × 5 = 135.

Answer:

Starting price is $50.70.

Next day the price is $50.70 + $17.75 = $68.45

This price then changed by: [tex]-3\frac{3}{4}\%=-3.75\%[/tex].

So in order to calculate that we do: [tex]68.45 - (3.75/100*68.45)=65.883125 =\$65.88[/tex]

Therefore final price is $65.88.

Yes, this is reasonable.

Answer:

(w * 2) + 5 = 9

Explanation:

Product means multiplication. Five more than means adding 5. So, add five to the answer of w times 2 is 9.

(w * 2) + 5 = 9

Thus the equation is 5 + 2w = 9 and the unknown number is 2.

Given,

Five more than the product of a number and 2 equals 9.

We will use the unknown number as w.

We will form an equation.

Find the equation.

Let the unknown number be w.

"Five more than the product of a number and 2 equals 9".

we can write this as:

5 + w x 2 = 9

5 + 2w = 9

Find the unknown number.

We have,

5 + w x 2 = 9

5 + 2w = 9

Subtract 5 on both sides.

5 + 2w - 5 = 9 - 5

2w = 4

Divide both sides by 2.

w = 2

Thus the equation is 5 + 2w = 9 and the unknown number is 2.

Answer:

there is no image

Step-by-step explanation:

Answer:

You need to use y=mx+b

In this case, m=1.5 so that means that y=1.5x

Now you must find out the y intercept which is "b" in y=mx+b

I think it is the first one (y=1.5x+72)

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

Explanation:

The given slope is m = 1.5

We want the line to go through (x,y) = (6,72). This means x = 6 and y = 72 pair up together.

We'll plug those m, x, and y values into the equation below to solve for b

y = mx+b

72 = 1.5*6+b

72 = 9+b

72-9 = b ... subtract 9 from both sides

63 = b

b = 63 ... y intercept

-------------------

Since m = 1.5 and b = 63, we go from y = mx+b to y = 1.5x+63

Answer:

From smallest to largest 1/4, 1/3,1/2

Step-by-step explanation:

As the data suggests: 1/4 would be the smallest, 1/3 is in the middle, and 1/2 is the largest sum.

1/4 = 0.25

1/3 ≈ 0.33

1/2 = 0.5

The fractions in order of size, smallest to largest, 1/4, 1/3, 1/2

Used the concept of ascending order that states,

Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right.

The numbers arranged in order from least to the greatest number is called Ascending order.

Given that,

The fraction is,

1/4, 1/2, 1/3

Now evaluate the fractions as

1/4 = 0.25

1/2 = 0.5

1/3 = 0.33

After arranging the number into ascending order, we get;

0.25, 0.33, 0.5

Or, 1/4, 1/3, 1/2

Therefore, the fractions in order of size, smallest to largest is,

1/4, 1/3, 1/2

Step-by-step explanation:

Answer: The middle 90% of incomes are between $6621.25 and $12378.75 .

Step-by-step explanation:

The critical z-value for 90% confidence = 1.645

Given: Mean income per household  =  $9500

standard deviation = $1750

then,  middle 90% of incomes are between $(9500-(1.645)(1750)) and (9500+(1.645)(1750))

i.e.  middle 90% of incomes are between $6621.25 and $12378.75.

Hence, the middle 90% of incomes are between $6621.25 and $12378.75 .
