The value of different f(x) for different value of 'x' in the given graph is f(-3) = -1 , f(-2)=0. f(-5)= 3, f(-4) =0

Given that, The f(x) graph we can observe that it is a shifted parabola.

We can translate the parabola vertically to produce a new parabola that is similar to the basic parabola. The function [tex]y=x^2 + b[/tex] has a graph which simply looks like the standard parabola with the vertex shifted b units along the y-axis. Thus the vertex is located at (0,b). If b is positive, then the parabola moves upwards and, if b is negative, it moves downwards.

Similarly, we can translate the parabola horizontally. The function[tex]y =(x-a)^2[/tex]has a graph which looks like the standard parabola with the vertex shifted a units along the x-axis. The vertex is then located at (a,0). Notice that, if a is positive, we shift to the right and, if a is negative, we shift to the left.

So, for the given question

b = parabola shift unit along y-axis = -1 units

a = parabola shift unit along x-axis = -3 units

So, equation of parabola = [tex]f(x)=y = (x+3)^2-1[/tex]

Now,

for x = -3. f(-3)=[tex](-3+3)^2-1=-1[/tex]

So, f(-3)= -1

x = -2. f(-2)=[tex](-2+3)^2-1=0[/tex]

So, f(-2)= 0

x = -5. f(-5)=[tex](-5+3)^2-1 = 3[/tex]

So, f(-5)= 3

x = -4. f(-4)=[tex](-4+3)^2-1=0[/tex]

So, f(-4)= 0

Therefore, from the graph f(x),  value of f(x) for diiferent value of x is f(-3)=-1. f(-2)=0.f(-5)=3.f(-4)=0.

The orthocenter is the point where a triangle's three altitudes intersect, and the centroid is the point where the three medians intersect.

The coordinates of the orthocenter of Δ RST is (3, 6).

An orthocenter of a triangle is the point at which altitudes drawn perpendicular from the vertex to the opposite sides of a triangle intersect. A triangle typically has three altitudes, and the intersection of all three altitudes is known as the orthocenter.

The orthocenter is the point where a triangle's three altitudes intersect, and the centroid is the point where the three medians intersect.

The midpoint of AD is (-1+3/2, 11+1/2) or (1, 6). Note that DC is a line that connects the vertex C and D, the midpoint of AB. The distance from D(1, 6) to C(7, 6) is 7 - 1 or 6 units.

If P is the centroid of the triangle XYZ, then PC = (2/3) DC.

So, the centroid is 2/3(6) or 4 units to the left of C. The coordinates of the centroid (P) are (7 - 4, 6) or (3, 6).

Answer:

x

Step-by-step explanation:

When you add them, you get 4/4x which is also known as 1x.

The inequality can be simplified to:

x > -1

And the graph can be seen in the image below.

Here we have the inequality:

5x + 8 > 3

To solve this, we need to isolate the variable x in one side of the inequality.

5x + 8 > 3

We subtract 8 in both sides:

5x > 3 - 8

5x > -5

Now we divide both sides of the inequality by 5.

x > -5/5

x > -1

Now, to graph this, we need to do an open circle at x = -1, and shade all the region to the right of this point, like in the example below.

The standard deviation of the number of residents in the sample who were born in Colorado is 7.82

PC = Indicates the real population of residents born in Colorado  

PC = 0.427 shows estimated proportion for residents born in Colorado

nC = 250 sample size selected

Let X = random variable of interest

n = 250 , p = 0.427

Now the probability mass function is given by

P(X) =  (nCx)(p)^x(1-p)^n-x

Here (nCx) means combinatory and its formula is:

nCx = n! / (n-x)!x!

Let's calculate the expected value by the given formula.

E(X) = np = 250 x 0.427 = 106.75

x is equal to the -10 or less than the -10

Inequality:

In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions. Inequalities can be posed either as questions, much like equations, and solved by similar techniques, or as statements of fact in the form of theorems. For example, triangle inequality states that the sum of the lengths of any two sides of a triangle is greater than or equal to the length of the remaining side. The mathematical analysis relies on many such inequalities (e.g., the Cauchy-Schwarz inequality) in the proofs of its most important theorems.

In mathematics, an inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions.[1] It is used most often to compare two numbers on the number line by their size. There are several different notations used to represent different kinds of inequalities:

The notation a < b means that a is less than b.

The notation a > b means that a is greater than b.

In either case, a is not equal to b. These relations are known as strict inequalities,[1] meaning that a is strictly less than or strictly greater than b. Equivalence is excluded.

In contrast to strict inequalities, there are two types of inequality relations that are not strict:

The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or, equivalently, at most b, or not greater than b).

The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).

The relation not greater than can also be represented by a ≯ b, the symbol for "greater than" bisected by a slash, "not". The same is true for not less than and a ≮ b.

The notation a ≠ b means that a is not equal to b; this inequation sometimes is considered a form of strict inequality.[2] It does not say that one is greater than the other; it does not even require a and b to be member of an ordered set.

In engineering sciences, less formal use of the notation is to state that one quantity is "much greater" than another,[3] normally by several orders of magnitude.

The notation a ≪ b means that a is much less than b.[4]

The notation a ≫ b means that a is much greater than b.[5]

This implies that the lesser value can be neglected with little effect on the accuracy of an approximation (such as the case of ultra relativistic limit in physics).

In all of the cases above, any two symbols mirroring each other are symmetrical; a < b and b > a are equivalent, etc.

The additional cost required to pay for a 30 minutes call is 49.4 cents.

What is a word problem?

A word problem is defined as a mathematical problem written in form of words or sentences. These are assigned to students to determine their hold on the concepts.

Calculation of cost of calling 30 minutes

The cost for calling 4 minutes is 7.6 cents

The cost for calling 1 minute is 7.6 / 4

= 1.9

The cost for calling 30 minutes = 1.9 × 30

= 57 cents

The word 'more' in the word problem specifies the additional cost needed to make a 30-minute call i.e. it requires the difference between the cost of a 4-minute call and a 30 minutes call.

More cost = còst for calling 30 minutes- cost for calling 4 minutes

= 57 - 7.6

= 49.4 cents

The triangle having vertices X(-7,-3), Y(-2,-5), Z(-4,-1)  is obtuse.

According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:

acute if [tex]a^{2} + b^{2} < c^{2}[/tex]

obtuse if  [tex]a^{2} + b^{2} > c^{2}[/tex]

right if  [tex]a^{2} + b^{2} = c^{2}[/tex]

XY = [tex]\sqrt{(-2 + 7)^{2} + (-5 + 3)^{2} }[/tex]

∴ XY = 5.38

YZ = [tex]\sqrt{(-4 + 2)^{2} + (-1 + 5)^{2} }[/tex]

∴YZ = 4.47

ZX = [tex]\sqrt{(-4 + 7)^{2} + (-1 + 3)^{2} }[/tex]

∴ ZX = 3.60

∴The longest side is XY = 5.38.

Hence, a = YZ, b = ZX and c = XY;

Consider [tex]a^{2} + b^{2}[/tex] :

= [tex]4.47^{2} + 3.60^{2}[/tex]

= 32.94.

Now consider [tex]c^{2}[/tex]:

= [tex]5.38^{2}[/tex]

Thus, [tex]a^{2} + b^{2} > c^{2}[/tex]
