Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, the statement that could be true for g is: D. g(-13) = 20.

In Mathematics, a range can be defined as the set of all real numbers that connects with the elements of a domain.

From the information provided, the domain and range of this function g(x) in interval notation is given by:

Function g(0) = 2 is false because it was stated that g(0) = -2. Also, g(-4) = -11 is outside the scope of the given range for this function.

Furthermore, function g(7) = -1 is not within the domain for the given function. However, g(-13) = 20 is within the domain for the given function and produces an output that is within the scope of the given range for this function.

The given exponential function is increasing so it will be growth and the percentage increase is 97%.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given function,

y = 7000(1.97)^x

As x increase the 1.97^x will be increased thus, y will be increased so it will be growth.

Suppose x = 0

y = 7000

Suppose x = 1

y = 1.97 x 7000

% increase = (1.97 x 7000 - 7000)/7000

% increase = 97 %

Hence "The given exponential function is increasing so it will be growth and the percentage increase is 97%".

The points that must be on the graph for the quantities to be proportional to each other are (2, 44), (3, 66) and (4, 88)

From the question, we have the following parameters that can be used in our computation:

Championship T-shirts sell for $22 each.

The above parameter means that

The unit rate of a T-shirt = $22

This can be represented as

Unit rate = 22

The interpretation of the above rate is that:

The number of n T-shirts is the unit rate multiplied by n

So, we have the following equation

Cost of n shirts = Unit Rate * n

When the number of shirts is 2, we have

Cost of 2 shirts = 22 * 2

Cost of 2 shirts = 44

When the number of shirts is 3, we have

Cost of 3 shirts = 22 * 3

Cost of 3 shirts = 66

When the number of shirts is 4, we have

Cost of 8 shirts = 22 * 4

Cost of 4 shirts = 88

So, the points are (2, 44), (3, 66) and (4, 88)

Answer:

A and C = 13 and D and E = 24

Step-by-step explanation:

The value of the given limits [tex]\lim_{x \to \infty} 1/x^2[/tex] is 0,[tex]\lim_{x \to \22} \frac{(x^2-4)}_(x-2)}[/tex] is 4  ,[tex]\lim_{x \to \pi} sinx\\[/tex] is 0 and [tex]\lim_{x \to \55} e[/tex] is e.

Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.

Because the value of that function at that point doesn't define.

a)

[tex]\lim_{x \to \infty} 1/x^2[/tex] by substitute limit 1/∞² = 0

b)

[tex]\lim_{x \to \22} \frac{(x^2-4)}_(x-2)}[/tex] here (x² - 4)/(x - 2) = (x - 2)(x + 2)/(x - 2) = (x + 2)

Putting x = 2 will give the limit as 2 + 2 = 4.

c)

[tex]\lim_{x \to \pi} sinx\\[/tex] herer put x to π so sinπ = 0.

c)

[tex]\lim_{x \to \55} e[/tex] here no variable thus e will be the answer.

Hence "The value of [tex]\lim_{x \to \infty} 1/x^2[/tex] is 0,[tex]\lim_{x \to \22} \frac{(x^2-4)}_(x-2)}[/tex] is 4  ,[tex]\lim_{x \to \pi} sinx\\[/tex] is 0 and [tex]\lim_{x \to \55} e[/tex] is e".

The probability that Jordan will win in three or fewer matches if they play 5 matches using binomial probability distribution is; 0.95636

The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability.

The general formula for binomial probability distribution is;

P(X = x) = nCx * p^(x) * (1 - p)^(n - x)

where;

Px = the probability of exactly x events occurring

x = the number of expected successful outcomes

n = the number of trials you perform

nCx = the number of different combinations for x items you test in n trials

We are given probability that Jordan wins the match as 1/3. Thus;

p = 1/3 = 0.333

Thus, probability that Jordan will win in three or fewer matches if they play 5 matches is;

P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)

From online binomial probability calculator, we have;

P(X ≤ 3) = 0.95636

Proved that ΔXYW ≅ ΔZYW

Consider the two triangles triangle XYW and triangle ZYW

According to SAS congruent rule if 2 sides and one angle of the one triangle is equal to the 2 sides and one angles of the another triangle, then both the triangles are congruent

The length of the side XY = The length of the side ZY

The line YW bisect the angle XYZ

Then the measure of angle XYW = The measure of angle ZYW

The length of the YW is common

Therefore the 2 sides and one angle of the triangle XYW is equal to the 2 sides and one angle of the triangle ZYW

Then the  triangles XYW and triangle ZYW are congruent

Given that, the nth term of a series represented by [tex]a_n=\frac{4^n}{5^{n+1}.n}[/tex].

A convergent series is a series whose partial sums tend to a specific number, also called a limit. A divergent series is a series whose partial sums, by contrast, don't approach a limit. Divergent series typically go to ∞, go to −∞, or don't approach one specific number.

The measure of the missing length of the triangle is 16 units.

According to the question,

We have the following information:

We have a figure of right-angled triangle where two sides are given.

In order to find the third side of this triangle, we will use the Pythagoras theorem.

So, we have the following expression:

[tex]AC^{2} = AB^{2} + BC^{2}[/tex]

[tex](20)^{2} = AB^{2} + (12)^{2}[/tex]

400 = [tex]AB^{2}[/tex] + 144

Subtracting 144 from both sides of the equation:

[tex]AB^{2}[/tex] = 400-144

[tex]AB^{2}[/tex] = 256

We know that the square root of 256 is 16 or in other words, the square of 16 is 256.

AB = 16 units

Hence, the measure of the missing length of the triangle is 16 units.

The value of 198.02 percent of £83.02 is £164.40

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

The value will be illustrated thus:

198.02% × £83.02

= 1.9802 × £83.02
