Answer: SECOND OPTION

Step-by-step explanation:

Substitute any value of n shown in the table attached into each function given in the options, and observe if you obtain the value of [tex]a_n[/tex] shown in the table.

Let's substitute n=1 (According to the table, you need to obtain [tex]a_n=3[/tex]):

For the first option:

[tex]f(1)=1+3=4[/tex]

For the second option:

[tex]f(1)=7(1)-4=3[/tex]  THIS IS THE FUNCTION

For the third option:

[tex]f(1)=3(1)+7=10[/tex]

 For the fourth option:

[tex]f(1)=1+7=8[/tex]

Therefore, the answer is the second option.

ANSWER

[tex]f(n) = 7n - 4[/tex]

EXPLANATION

The terms of the sequence are;

[tex]3,10,17,24,31,...[/tex]

This implies that,

[tex]a_1=3[/tex]

The constant difference is

[tex]d = 10 - 3 = 7[/tex]

The nth term of the sequence is;

[tex]a_n=a_1+d(n-1)[/tex]

[tex]a_n=3+7(n-1)[/tex]

[tex]a_n=3+7n - 7[/tex]

[tex]a_n=7n-4[/tex]

Or

[tex]f(n) = 7n - 4[/tex]

The correct choice is B.

Answer:

what is √25x^2y^2/√xy in simplest from? Assume x≥o and y≥0

The correct answer to this question is 5√xy

Step-by-step explanation:

The given expression in its simplest form is [tex]5 \sqrt{xy}[/tex]

From the question,

We are to evaluate sqrt 25x^2y^2/sqrt xy in its simplest form.

First, we will write the given expression properly

The given expression is

[tex]\frac{\sqrt{25x^{2} y^{2} } }{\sqrt{xy} }[/tex]

Now, the expression can be evaluated as shown below

[tex]\frac{\sqrt{25x^{2} y^{2} } }{\sqrt{xy} }[/tex]

[tex]\frac{\sqrt{25 } \times \sqrt{x^{2} y^{2}} }{\sqrt{xy} }[/tex]

This becomes

[tex]\frac{5 \times xy }{\sqrt{xy} }[/tex]

This becomes

[tex]\frac{5 \times xy}{(xy)^{\frac{1}{2} } }[/tex]

This can be written as

[tex]5 \times xy \div (xy)^{\frac{1}{2} }[/tex]

By applying one of the laws of indices

We get,

[tex]5 \times (xy)^{1-\frac{1}{2} }[/tex]

[tex]5 \times (xy)^{\frac{1}{2} }[/tex]

[tex]5 \times \sqrt{xy}[/tex]

[tex]5 \sqrt{xy}[/tex]

Hence, the given expression in its simplest form is [tex]5 \sqrt{xy}[/tex]

Answer:

Yeah true

Step-by-step explanation:

Because it makes sense

It is true that when developing a proof, focusing on the "given" information is crucial as it forms the foundation of the logical argument leading to the conclusion that needs to be proven.

When developing a plan for a proof, it is indeed important to look at the "given" information. This is true because in the context of mathematical proofs, the "given" information represents the starting point from which you will build you argument to reach a conclusion. These are the facts, definitions, or previously proven theorems that can be used in establishing the validity of the statement you are tasked to prove.

To develop a successful proof, one generally follows a systematic approach:

This structured approach to problem-solving involves using what you know to logically arrive at a conclusion that was previously unknown or needs to be proven. This method not only applies to mathematics but also to other fields that require logical reasoning and evidence-based conclusions.

By factoring out and simplifying, we can see that given expression is divisible by both 30 and 37.

The method for solving this question involves using certain properties of numbers and exponents. Firstly, observe the expressions (36^5-6^9) and (38^9-38^8). You can factor out 6^5 from the first expression and 38^8 from the second expression, giving you 6^5(6^4-1) and 38^8(38-1) respectively.

You will notice that 6^4-1 is 1295 and 38-1 is 37.  Both 1295 and 37 are divisible by 37, rendering the whole expression divisible by 37. Moreover, 1295 is divisible by 5 and 6^1 is divisible by 6, making the expression divisible by 5*6 = 30.

Therefore, the whole expression is divisible by both 30 and 37.

To prove the divisibility of the expression, we factor and simplify it. The expression is divisible by both 30 and 37 due to its factors.

To prove that the value of the expression b(36^5 - 6^9)(38^9 - 38^8) is divisible by 30 and 37, we can factor out 6 from both terms in each parenthesis.

This gives us b(6^4)(6^9 - 1)(38^8)(38 - 1).

Next, we divide each term by 6, giving us b(6^3)(6^9 - 1)(38^8)(38 - 1)/6.

We can simplify this expression further by factoring out 2 from both terms in the first parentheses, giving us 2^3b(6^6)(6^3 - 1)(38^8)(38 - 1)/6.

Now we can see that the expression is divisible by both 30 and 37, since it contains factors of 2, 3, 5, and 37.

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

y------> the total cost

x------> the number of shirts

we know that

The linear equation is

[tex]y=1.50x+4.50[/tex] ------> equation of the line

To graph the line find the intercepts

The y-intercept is the value of y when the value of x is equal to zero

The x-intercept is the value of x when the value of y is equal to zero

Find the y-intercept

For x=0

[tex]y=1.50(0)+4.50=4.50[/tex]

The y-intercept is the point (0,4.50)

Find the x-intercept

For y=0

[tex]0=1.50x+4.50[/tex]

[tex]1.50x=-4.50[/tex]

[tex]x=-4.50/1.50=-3[/tex]

The x-intercept is the point (-3,0)

Answer:

33 grams

Step-by-step explanation:

We multiply the total weight of the choco. bar (94 grams) by 0.36 to obtain the number of grams of cocoa present:

0.36(94 grams) = 33.04 grams.

The bar contains 33.04 grams of cocoa.  Round this up to 33 grams.

Answer: 33.84 gr

Step-by-step explanation:

You have the following information given in the problem:

- Hans chocolate bar is 36% cocoa.

- The chocolate bar weighs 94 grams.

Therefore, to calculate the amount of grams of cocoa it contains (which you can call x), you must multiply the weight of the chocolate bar by the percentafe of cocoa it has

Therefore, you obtain the following result:

[tex]x=94gr*0.36\\x=33.84gr[/tex]

Let's reason through it.

We are given the inequality that says, in English, that the absolute value of ten times x is greater than -2.

Let's consider three cases:

x is negative

- When x is negative the number in the absolute value will be negative. But because it is inside the absolute value, the number becomes positive. Therefore, for any x that is negative (however small or large), the left side will be positive. Any positive value (however small) is greater than a negative value, so the inequality is satisfied in this case.

x is positive

- When x is positive, the number inside the absolute value will be positive. The absolute value of a positive number is itself, so the left hand side will be positive again. Then, for all positive values of x (however small or large), the inequality will be satisfied because any positive value is larger than -2.

x is zero

- Even in the case of zero, when the left hand side will be zero, the equality is satisfied. This is because zero is greater than -2. If this doesn't immediately make sense, imagine the two numbers on the number line. 0 is to the right of -2, so it is larger.

Since we cannot find a value for x that does not satisfy the inequality, the solution to the inequality is all values of x. See the attached image.

Step-by-step explanation:

Answer:

f ( -2 ) = 30

g ( -2 ) = 3

Step-by-step explanation:

when it says f(x) and then has f(-2) - you fill in all x's in the equation with -2.. like this:

f(x) = -7(-2-2) +2                         g(x) = 2(-2)^2 -5

f(x) = -7(-4) +2                             g(x) = 2(4) -5

f(x) = 28 + 2                                g(x) = 8 - 5

f(x) = 30                                      g(x) = 3

Answer: 36

Step-by-step explanation:

The length and width of the rectangle is 12 and 10 respectively.

Let the consecutive integers be :

Area of rectangle = Length × width

120 = a(a + 2)

120 = a² + 2a

a² + 2a - 120 = 0

a² - 10a + 12a + 120 = 0

a(a - 10) + 12(a - 10)

a = 10 or a = -12

The width cannot be negative, Hence, width = 10

Length = a + 2

Length = 10 + 2

Length = 12

The length and width of the rectangle is 12 and 10 respectively.
