Answer:
(b) [tex]x \ge -3[/tex]
Step-by-step explanation:
Given
[tex]g(x) = \sqrt{x + 3}[/tex]
Required
The domain
For [tex]g(x) = \sqrt{x + 3}[/tex] to be defined, the following must be true
[tex]\sqrt{x + 3} \ge 0[/tex]
Square both sides
[tex]x + 3 \ge 0[/tex]
Subtract 3 from both sides
[tex]x \ge -3[/tex]
Hence, the domain is:
(b) [tex]x \ge -3[/tex]

The x- intercepts of a parabola are (0,-6) and (0,4). The parabola crosses the y- axis at -120. Lucas said that an equation for the parabola is y=5x^2+10x-120 and that the coordinates of the vertex are (-1, -125). Do you agree or disagree? List why?
Given:
The x- intercepts of a parabola are (0,-6) and (0,4).
The parabola crosses the y- axis at -120.
Lucas said that an equation for the parabola is [tex]y=5x^2+10x-120[/tex] and that the coordinates of the vertex are (-1, -125).
To find:
Whether Lucas is correct or not.
Solution:
The x- intercepts of a parabola are (0,-6) and (0,4). It means (x+6) and (x-4) are the factors of the equation of the parabola.
[tex]y=a(x+6)(x-4)[/tex] ...(i)
The parabola crosses the y- axis at -120. It means the equation of the parabola must be true for (0,-120).
[tex]-120=a(0+6)(0-4)[/tex]
[tex]-120=a(6)(-4)[/tex]
[tex]-120=-24a[/tex]
Divide both sides by -24.
[tex]\dfrac{-120}{-24}=a[/tex]
[tex]5=a[/tex]
Substituting [tex]a=5[/tex] in (i), we get
[tex]y=5(x+6)(x-4)[/tex]
[tex]y=5(x^2+6x-4x-24)[/tex]
[tex]y=5(x^2+2x-24)[/tex]
[tex]y=5x^2+10x-120[/tex]
So, the equation of the parabola is [tex]y=5x^2+10x-120[/tex].
The vertex of a parabola [tex]f(x)=ax^2+bx+c[/tex] is:
[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]
In the equation of the parabola, [tex]a=5,b=10,c=-120[/tex].
[tex]-\dfrac{b}{2a}=-\dfrac{10}{2(5)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{10}{10}[/tex]
[tex]-\dfrac{b}{2a}=-1[/tex]
Putting [tex]x=-1[/tex] in the equation of the parabola, we get
[tex]y=5(-1)^2+10(-1)-120[/tex]
[tex]y=5-10-120[/tex]
[tex]y=-125[/tex]
So, the vertex of the parabola is at point (-1,-125).
Therefore, Lucas is correct.

Parallelogram A B C D is shown. Line segment X Y goes from point X on side A B to point Y on side C D to form 2 trapezoids.
Figure ABCD is a parallelogram. Two trapezoids are created using line segment XY such that AX ≅ CY.
What is true about the areas of the trapezoids?
Each area is equal to half of the area of ABCD.
The area of AXYD is less than the area of BXYC.
The area of AXYD is greater than the area of BXYC.
Each area is equal to the area of ABCD.
Answer:
Each area is equal to half the area of ABCD
Step-by-step explanation:
AX ≅ CY
In parallelogram, opposite sides are equal.
AB = CD
AX + XB = CY + YD
CY + XB = CY + YD
XB = CY + YD - CY
XB = CY
Both trapezoids have equal area
Area of AXYD + area of BXYC = area of ABCD
Answer:
A. ) Each area to equal to half of the area of ABCD

Answer:
[tex]g(-2)=20[/tex]
Step-by-step explanation:
Given [tex]g(x)=2x^2-2x+8[/tex], substitute what is in the parentheses for [tex]x[/tex] to find an output.
For [tex]g(-2)[/tex], the term [tex]-2[/tex] is in the parentheses. Thus, substitute [tex]x=-2[/tex] into [tex]2x^2-2x+8[/tex] to find [tex]g(-2)[/tex]:
[tex]g(-2)=2(-2)^2-2(-2)+8,\\g(-2)=2\cdot 4+4+8,\\g(-2)=8+4+8,\\g(-2)=\boxed{20}[/tex]
Answer:
a) 8
b) 20
c) 20
Step-by-step explanation:
a) Insert X=0 from g(0) to the equation: 2(0) power of 2 - 2x0 +8.
b) Insert X=(-2) from g(-2) to the equation: 2(-2) power of 2 - 2x(-2) +8.
c) Insert X=3 from g(3) to the question 2(3) power of 2 - 2x3 +8.

(iii) Show it in a Venn diagram. In a survey of 120 students, 60 drink milk, 50 drink curd and 20 students drink milk as well curd then, Draw a Venn diagram to illustrate the above information. (ii) Find the number of students who drink neither of them.
Answer:
Step-by-step explanation:
As you can see in the venn diagram that is attached below, The individuals that drink milk are in green, those that drink curd are in yellow, and those that drink both are in light blue. Since the sum of those that drink milk with those that drink curd is 110 and a total of 120 students were surveryed. Then this means that 10 of the students neither drink milk nor curd. These students are represented outside of the venn diagram but within the box of surveyed students.

Your organization has 20 employees who need an accounting software update installed. Due to a miscommunication, the purchaser only paid to update 10 licenses. The software company issued a paper license and a single key for updating 10 users. Since this is an enterprise paper license, there is no mechanism that enforces a limit to the number of times the key can be used, so you decide to go ahead and update all 20 users. What are the possible consequences of this decision? (Select TWO.)
Answer:
a. you risk losing your job
b. you expose your company to litigation by violating the software agreement.
Step-by-step explanation:
Doing this puts our job at a risk and it also exposes the company that you work for to litigation. Legally, there is an agreement that puts a limit to the total number of licenses that should be in use. When you use more licenses than you should, this could be regarded as theft. Normally the best thing that you should do is to ask purchasing that they make payments for another 10 licenses. It is very likely that this software company would know of this violation. as the users try to register this software, the software company could get knowledge of this. The activations are not to be shared.

Pls help me with this set problem
(1) False. [tex]\{0\}\in\mathscr{U}[/tex] is saying "the set containing only 0 (that is, {0}) is an element of [tex]\mathscr U[/tex]", but this is not the case. [tex]\mathscr U[/tex] is the set containing only 0 and 1.
(2) True. [tex]\{0\}\subset\mathscr{U}[/tex] means "the set {0} is a subset of [tex]\mathscr{U}[/tex]". 0 itself is an element of [tex]\mathscr U[/tex], so {0} is indeed a subset of [tex]\mathscr U[/tex].
(3) True. 0 is clearly an element of [tex]\mathscr U[/tex].
(4) False. This statement says "0 is a subset of [tex]\mathscr U[/tex]" but 0 itself is not a set, it's a number.

There are 120 teachers in a ABC school. Determine the value of k using the systematic sampling technique to select a sample of 40 teachers.
Answer:
K=30
Step-by-step explanation:
120÷4 = 30
k=30
The value of k for selecting 40 teachers out of 120 is 1 / 3.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that there are 120 teachers in an ABC school and 40 teachers need to be selected,
The value of k will be calculated by the concept of probability as below,
k = Number of favourable outcomes / Number of sample
k = 40 / 120
k = 1/3
Therefore, the value of k for selecting 40 teachers out of 120 is 1 / 3.

sheesh i only seeing 5 and 18find the equation of the straight line passing through the point (0,2) which is perpendicular to line y=1/4x+5
Answer:
y = -4x + 2
Step-by-step explanation:
Given the following data;
Points (x1, y1) = (0, 2)
Perpendicular line = y = ¼x + 5
To find the equation of the straight line passing;
Mathematically, the equation of a straight line is given by the formula: y = mx + c
Where;
m is the slope.x and y are the pointsc is the intercept.From the question, we can deduce that the slope (m) of the perpendicular line is ¼.
y = ¼x + 5 = mx + c
Since the points are perpendicular to the equation of line, it must have a slope that is its negative reciprocal because the slopes of perpendicular lines are negative reciprocals of each other.
Therefore, ¼ = -4
Next, we would write the equation of the straight line using the following formula;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - 2 = -4(x - 0)
y - 2 = -4x - 0
y - 2 = -4x
y = -4x + 2
