Answer:

  f(x) = x^3 -4x^2 +4x -16

Step-by-step explanation:

If 2i is a zero, then its conjugate, -2i, is also a zero. When p is a zero, then (x-p) is a factor. For the three given zeros, the factors are ...

  f(x) = (x -4)(x -2i)(x +2i)

  f(x) = (x -4)(x^2 +4)

  f(x) = x^3 -4x^2 +4x -16 . . . . . . multiplied out to standard form

Now, f(2) = (2 -4)(2^2 +4) = (-2)(8) = -16. This is the required value, so we're done.*

  f(x) = x^3 -4x^2 +4x -16

_____

* If the required value were something else, then we would have to multiply the f(x) we found by some factor to make the value of f(2) come out right. That factor would be ...

  k = (desired f(2))/(f(2) for our function so far)

In this case, ...

  k = -16/-16 = 1

Answer:

f(1) = 10, f(2) = 17, f(3) = 24, f(4) = 31, f(5)=36, f(6)=45

Step-by-step explanation:

f(1) = 7(1) + 3     f(2) = 7(2) + 3   f(3) = 7(3) + 3    f(4) = 7(4) + 3   f(5) = 7(5) + 3

 f(1) = 7 + 3        f(2) = 14 + 3      f(3) = 21 + 3     f(4) = 28 + 3      f(5) = 35 + 3

   f(1) = 10             f(2) = 17            f(3) = 24            f(4) = 31            f(5) = 38

f(6)= 7(6) + 3

 f(6) = 42 + 3

    f(6) = 45

Answer:

The price is now $44

Step-by-step explanation:

The original price is $55

The discount percent is20%

Calculate the savings: 20% of $55 = $11

Subtract the savings from the original price to get the sale price: $55 - $11 = $44

Answer:

m = - 1

Step-by-step explanation:

Given

- 9m - 86 = - 75 + 2m ( subtract 2m from both sides )

- 11m - 86 = - 75 ( add 86 to both sides )

- 11m = 11 ( divide both sides by - 11 )

m = - 1

Question:

The probability of rolling a number less than 3 on a number cube is 2/6 . Jennifer rolls a number cube 60 times. How many times should Jennifer expect to roll a number less than 3?

Answer:

The expected value is 20

Step-by-step explanation:

Given

[tex]n= 60[/tex] --- Number of rolls

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

Required

Determine the expected value

Expected value (E(x)) is calculated using:

[tex]E(x) = n * p[/tex]

Substitute values for n and p

[tex]E(x) = 60 * \frac{2}{6}[/tex]

[tex]E(x) = \frac{120}{6}[/tex]

[tex]E(x) = 20[/tex]

Answer:

b=(3a/(2h)), x=(y-b)/m

Step-by-step explanation:

Simply isolate b ;

a=2/3bh, Divid both sides by 2/3 and h

a/(2/3h)=b, simplify

b=(3a/(2h))

Simply isolate x;

y=mx+b; subtract b from both sides and divide by m

y-b=mx

(y-b)/m=x

Answer:

11.  x = 3 and BC = 8.

Step-by-step explanation:

FA = 2BC so

3x + 7 = 2(3x - 1)

3x + 7 = 6x - 2

-3x = -9

x = 3

and BC = 3(3) - 1 = 8.

Answer:

EF / LM = 1 / 4

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.

Dilation is the enlargement or reduction in the size of a figure. If a point A(x, y) is dilated by a scale factor of k, the new point is at A'(kx, ky).

Translation is the movement of a point right, left, up or down. If a point A(x, y) is translated a units left and b units down, the new point is at A'(x - a, y - b).

Translation preserves the size and shape of an object. Dilation preserves the shape but not the size.

Cdef maps to jklm with the transformation (x,y) to (4x,4y) to (x-4,y-9).

CDEF was first dilated by a scale factor of 4 to get (4x,4y) before it was translated by (x-4,y-9). Since dilation changes the size of the figure, hence JKLM would be 4 times the size of CDEF. Therefore:

LM / EF = 4

EF / LM = 1 / 4

Answer: Package C

Step-by-step explanation:

The best buy will be the one that is cheapest per pound.

Package A = 4.98 /2 = $2.49 per pound

Package B = 12.25/5 = $2.45 per pound

Package C = 18.80/8 = $2.35 per pound

Package D = 23.70/10 = $2.37 per pound

Package C has the lowest price per pound at $2.35 and so is the best buy.

The inequality when rewritten with first with zero on one side and secondly with one rational expression on the other side gives;

1) Option A; add -3 to both sides

2) Option C; multiply both sides by (x-2)

The inequality we want to rewrite is;

[3/(x + 2)] + 4 ≥ 3

Now, when working with fractions of equations, when we want to simplify it, we do so by multiplying each term by the LCM of the denominators.

However, in this case, we want to first make the inequality to have zero on one side. Thus, to do that, we have to get rid of the 3 on the right by adding 3 to both sides of the inequality.

Now, if we want to make one rational expression to be on one side, then we need to multiply both sides by the LCM of the denominator which is (x + 2).

Answer:

The first graph is the graph of the solution set of the inequality  [tex]-\frac{3}{5}[/tex] x ≥ 9

Step-by-step explanation:

If multiply or divide the two sides of the inequality by a negative number, then we must reverse the sign of the inequality

Example:

2 < 3, when we divide both sides by -1, then it will be -2 > -3

Let us solve the question

∵ [tex]-\frac{3}{5}[/tex] x ≥ 9

→ To find x divide both sides by [tex]-\frac{3}{5}[/tex]

∵ [tex]-\frac{3}{5}[/tex] is a negative number

→ From the rule above

∴ Reverse the sign of inequality

∴ x ≤ -15

∵ We have an equal sign with the sign of inequality

∴ The vertex of the arrow should be bold

∵ The sign of inequality is smaller than

∴ The arrow must be pointed to the left ⇒ (negative direction)

∵ x ≤ -15

∴ The arrow represents it has a bold starting point at -15 and pointed

   to the left

∴ The answer is the first graph
