Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]

Given that:

[tex]f(x) = 2(x - 2)^2 - 8[/tex]

To identify the true statement, I will make use of graphical method.

See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]

From the attached graph, we can see that the graph as a minimum at:

[tex](x,y) = (2,-8)[/tex]

And it opens upward.

This implies that the minimum y-value of f(x) is at -8, and it has no maximum.

In other words, the range of the function is:

[tex]f(x) \ge -8[/tex]

Hence, the true statement is option (a):

The range of f(x) is [tex]y \ge -8[/tex]

Answer:

  -4 1/8

Step-by-step explanation:

Many people find it easier to factor out -1, then do the addition. The fractions need a common denominator before they can be added. A suitable denominator that is a multiple of both 4 and 8 is 8.

The fraction 1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8.

__

So, the problem can be rewritten as ...

  -(1 7/8 +2 2/8)

  = -((1+2) +(7/8 +2/8))

  = -(3 +9/8)

The fraction 9/8 is an improper fraction equal to 8/8 +1/8 = 1 1/8. Then the sum is ...

  -(3 +1 1/8) = -4 1/8

Step-by-step explanation:

Answer:

30.5 meters

10.5 meters

Step-by-step explanation:

x = length

y = width

x = y + 20

2x + 2y = 82 (the perimeter of a rectangle)

using the first equation as substitute in the second equation we get

2×(y + 20) + 2y = 82

2y + 40 + 2y = 82

4y = 42

y = 42/4 = 21/2 = 10.5 meters

x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters

Answer:

  = 0.108

Step-by-step explanation:

Use a calculator or long division.

When using long division, it is convenient to move the decimal points in both numbers to the right 2 places. This makes the divisor an integer, so makes it easier to keep track of appropriate place value in the quotient.

Answer:

£180, £120 and £60.

Step-by-step explanation:

The number of parts = 3 + 2 + 1 = 6.

360 / 6 = 60, so the shares are:

3*60 = 180

2*60 = 120

1 * 60 = 60.

The distribution of £360 in the ratio of 3:2:1 will be  £180, £120 and £60.

What is a ratio?

In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.

The number of parts = 3 + 2 + 1 = 6.

360 / 6 = 60, so the shares are:

3  x 60 = 180

2 x 60 = 120

1  x 60 = 60.

Hence the distribution of £360 in the ratio of 3:2:1 will be  £180, £120 and £60.

Dividing the segments, it is found that:

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

[tex]K - J = \frac{1}{n}(J - L)[/tex]

And this is the answer to option b.

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

Option a:

If [tex]\mathbf{n = 4}[/tex], it has that:

[tex]K - J = \frac{1}{4}(J - L)[/tex]

This is applied to find both the x-coordinate and the y-coordinate of K.

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

Thus:

[tex]K - J = \frac{1}{4}(J - L)[/tex]

[tex]x - 4 = \frac{1}{4}(4 - 0)[/tex]

[tex]x - 4 = 1[/tex]

[tex]x = 5[/tex]

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

Thus:

[tex]K - J = \frac{1}{4}(J - L)[/tex]

[tex]y - (-5) = \frac{1}{4}(-5 - (-7))[/tex]

[tex]y + 5 = \frac{2}{4}[/tex]

[tex]y = \frac{1}{2} - 5[/tex]

[tex]y = \frac{1}{2} - \frac{10}[2}[/tex]

[tex]y = -\frac{9}{2}[/tex]

The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]

Answer:

As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.

First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]

z2=−4±42−4×1×16√2×1=−4±16−64√2

=−4±−48√2=−2±12−−√i=−2±23–√i

=4(−12±3√2)i

=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2

=4e2kiπ3

As this is the value of z2 , whereas we want z , we need to take the square roots of both sides

z=4–√ekiπ3+nπ , where n∈0,1

=2e(k+3n)iπ3

=2cis((k+3n)iπ3)

As we have two values of k and two values of n , this gives us four solutions.

Writing these angles in terms of degrees, we have: 60, 120, 240 and 300

Evaluating, we end up with the four solutions

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Step-by-step explanation:

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a

X1,2=(-4+-√[16–16*4])/2

After you solve that you substitute back z^2 = x
