Using translation concepts, it is found that the correct option regarding the function is:

The function h(x) is decreasing on the interval (3, ∞).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent function is given by:

[tex]f(x) = \sqrt{x}[/tex]

Which increases on (0, ∞).

The translated function is given by:

[tex]g(x) = -2\sqrt{x - 3}[/tex]

With the translation, the domain is now (-3, ∞), and the function is decreasing, hence the correct option is given by:

The function h(x) is decreasing on the interval (3, ∞).

The complex number in rectangular form z = (5√3 / 4) - i 5/4 is equivalent to the complex number in polar form z = 5/2 · (cos 11π/6 + i sin 11π/6). (Correct choice: C)

Complex numbers are elements of the form z = a + i b, where [tex]a, b \in \mathbb{R}[/tex]. In other words, represents a generalization from real numbers. The polar form of a complex number is shown below:

[tex]z = r\cdot (\cos \theta + i \,\sin \theta)[/tex]     (1)

Where:

The norm is determined by Pythagorean theorem and the direction by inverse trigonometric reason. If we know that z = (5√3 / 4) - i 5/4, then its polar form is shown below:

Norm

[tex]r = \sqrt{\left(\frac{5\sqrt{3}}{4} \right)^{2}+\left(-\frac{5}{4} \right)^{2}}[/tex]

r = 5/2

Direction

[tex]\theta = \tan^{-1} \left[\frac{\left(-\frac{5}{4} \right)}{\left(\frac{5\sqrt{3}}{4} \right)} \right][/tex]

θ = 11π/6 rad

Thus, the complex number in rectangular form z = (5√3 / 4) - i 5/4 is equivalent to the complex number in polar form z = 5/2 · (cos 11π/6 + i sin 11π/6).

Step-by-step explanation:

Analysis:

(1) Translate square A two squares right

(a, b) ⇒ ( a + 2, b)

{ (1, 4)          {(3, 4)

{ (1, 1)   ⇒   { (3, 1)

(2) ... one square up:

(a, b) ⇒ (a, b + 1)

{ (3, 4)           { (3, 5)

{ (3, 1)    ⇒    {  (3, 2)

{   (5, 1)       {      (5, 2)

Answer:

192

Step-by-step explanation:

so you basically make an equation like this:

4*4(5+7)

4*4(12)

4*48

=192

The function on the table is decreasing on the interval [-2, 0).

A function is decreasing if, as x increases, f(x) decreases.

We can see that at x = -2, f(-2) = 12.

Then at x = 0, f(0) = 0.

And for the value after that:

x = 1, f(1) = 3

So now the function increases. Then we conclude that the function is decreasing on the interval [-2, 0), and after that the function increases.

The probability that a student, chosen at random, does not study chemistry is 20/41.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Here, Total number of student = 41

         Student who does not study chemistry = 20

So, the probability = favorable outcome / total outcomes

             P(not studying chemistry) = 20 / 41

Thus, The probability that a student, chosen at random, does not study chemistry is 20/41.

Step-by-step explanation:

If we make a list of all the sums that we can get, we have:

1+2, 1+3, 1+4, 1+5, 1+6, 2+3, 2+4, 2+5, 2+6, 3+4, 3+5, 3+6, 4+5, 4+6, 5+6

Answer:

first 2 options and 5th option are true

Step-by-step explanation:

locate y = - 4 on the y- axis. then a horizontal line through y = - 4 intersects the curve at x = - 2 and x = 1

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

the axis of symmetry is a vertical line through the vertex with equation

x = c ( c is the value of the x- coordinate of the vertex )

vertex = ( - [tex]\frac{1}{2}[/tex], - 6 )

equation of axis of symmetry is x = - [tex]\frac{1}{2}[/tex]

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

the minimum value is the y- coordinate of the vertex

that is the minimum value of f(x) is - 6

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

given a parabola in standard form

ax² + bx + c ( a ≠ 0 )

• if a > 0 then graph opens up

• if a < 0 then graph opens down

Here the graph opens up , then coefficient of f(x) is positive

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

the solutions to f(x) = 0 are the values of x on the x- axis where the graph crosses.

the solutions are x = 2 and x = - 3
