The function f(x) is graphed below. How many points on the graph represent a relative minimum? PLEASE need help i don't understand. Need help NOWWW!!!

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".

Answer: 0.06 sq km

Step-by-step explanation:

We first convert each dimension from meters to kilometers. 300 meters is equal to 0.3 kilometers. 200 meters is 0.2 kilometers. We now compute the area: 0.3 km * 0.2 km = 0.06 sq km.

The conversion of 230.2 g to metric ton is given by 0.0002302 metric tons.

Grams (g) and metric ton (MT) are the SI units of mass. Scientist measure various things with different units. The following are measures and their units;

Convert metric ton to grams:

1 metric ton = 1,000,000 grams

230.2 g = 230.2 ÷ 1,000,000

= 0.0002302 metric tons

Therefore, it can be said that 230.2 g is equivalent to 0.0002302 metric tons

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)

The first guitar lesson will cost (E $80

The cost of the first lesson is solved by comparing the costs

Since the cost of the first lesson is twice the cost of each additional lessons, double counting the first lesson makes the total number of lesson to be 9

if 9 lessons costs $360 then 1 lesson will cost

9 = 360

1 = ?

cross multiplying

8 * ? = 360 * 1

? = 360 / 9

? = 40

The unit cost is 40 taking the double counts makes the first lesson to be 2 * 40 = $80 then other lessons are 40

The unit price for brand A is $0.0517 and the unit price for brand B is $0.0828. Based on the unit price Brand A is better to buy.

Given that, Brand A has a box of 42 forks for $2.17. Brand B has a box of 48 forks for $3.97.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

The cost of each fork of brand A

= 2.17/42

= $0.0517

The cost of each fork of brand B

= 3.97/48

= $0.0828

Therefore, the unit price for brand A is $0.0517 and the unit price for brand B is $0.0828. Based on the unit price Brand A is better to buy.

A and C = 13 and D and E = 24

Step-by-step explanation:

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 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

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.

Next term in the series is [tex]a_{n+1}=\frac{4^{n+1}}{5^{n+2}.(n+1)}[/tex]

Now, the ratio is [tex]|\frac{a_{n+1}}{a_n}| =|\frac{\frac{4^{n+1}}{5^{n+2}.(n+1)}}{\frac{4^n}{5^{n+1}.n}}}|[/tex]

The empty space can be found by subtracting the load from the capacity of the truck. The attached calculator output shows there is room for an addition 0.0725 tons.

My-Lien will have enough room to move the gravel.

Alternate solution

You can convert 3 5/16 to a decimal: 3.3125. Clearly, this amount is less than 3.3850.

The balance of the account at the end of 21 years, given the deposit amount and the interest rate is $10, 351. 41

The balance on the account at the end of 21 years is the future value of the amount in the account today. This means that this balance can be found by the formula:
= Amount deposited x ( 1 + rate) ^ number of years
