Step-by-step explanation:

keeping in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

[tex]\bf \stackrel{\textit{x-intercept}}{(\stackrel{x_1}{6}~,~\stackrel{y_1}{0})}\qquad \stackrel{\textit{y-intercept}}{(\stackrel{x_2}{0}~,~\stackrel{y_2}{5})} ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{6}}}\implies -\cfrac{5}{6}[/tex]

[tex]\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-\cfrac{5}{6}}(x-\stackrel{x_1}{6}) \\\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{6}}{6(y-0)=6\left(-\cfrac{5}{6}(x-6) \right)}\implies 6y=-5(x-6) \\\\\\ 6y=-5x+30 \implies 5x+6y=30[/tex]

The standard form of the line with an x-intercept of 6 and a y-intercept of 5 is -5x + 6y = 30.

The standard form of a linear equation is given by the equation Ax + By = C, where A, B, and C are real numbers and A and B are not both zero. To find the standard form of the line with an x-intercept of 6 and a y-intercept of 5, we can use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept.

First, let's find the slope using the two intercepts. The slope is (y-intercept - x-intercept) / (0 - 6) = (5 - 0) / -6 = -5/6.

Now, we can substitute the slope and the y-intercept into the standard form equation to get: (-5/6)x + y = 5. Multiplying through by 6, we get -5x + 6y = 30. Therefore, the standard form of the line is -5x + 6y = 30.

Answer:

The sixteenth term is (7.5y - 6.5x).

Step-by-step explanation:

The first term of the A.P. is given to be x and the common difference is assumed to be d.

So, the third term = y = x + (3 - 1)d {Given that the third term is y}

Then, 2d = y - x

⇒ [tex]d = \frac{y - x}{2}[/tex]

Therefore, the sixteenth term of the A.P. will be = x + (16 - 1)d

= [tex]x + 15 \times \frac{y - x}{2}[/tex]

= x + 7.5y - 7.5x

= 7.5y - 6.5x (Answer)

Answer:

The sixteenth term is [tex]x+\frac{15(y-x)}{2}[/tex].

Step-by-step explanation:

Given,

[tex]a_1=x[/tex]

[tex]a_3=y[/tex]

And also given, [tex]T_n=a+(n-1)d[/tex]

We have to find out the 16th term of given A.P.

Firstly, we will find out the common difference(d).

Common difference(d) is calculated by given formula.

[tex]T_3=a+(n-1)d[/tex]

On putting the values, we get;

[tex]y=x+(3-1)d\\\\y=x+2d\\\\2d=y-x\\\\d=\frac{y-x}{2}[/tex]

Now the value of 'd' is calculated, so we can find out the 16th term by using the formula.

[tex]T_{16}=x+(16-1)\frac{y-x}{2}\\\\T_{16}=x+15\times\frac{y-x}{2}\\\\ T_{16}=x+\frac{15(y-x)}{2}[/tex]

Hence The sixteenth term is [tex]x+\frac{15(y-x)}{2}[/tex].

Answer:

a. y = 0.012x²

b. 4.80 m

c. 25 m/s

Step-by-step explanation:

a. First, we need to determine what kind of function this is (linear, quadratic, etc.).

Logically, the function must pass through the origin, so we can compare the ratios between points.

Let's look at (5.00, 0.30) and (10.00, 1.20).  When we double the speed, the depth quadruples.  That tells us this must be a quadratic equation.

y = kx²

Plug in a point to find k:

0.30 = k (5.00)²

k = 0.012

Therefore, the equation is:

y = 0.012x²

We can check our answer by plugging in more points.

1.20 = 0.012 (10.00)²

2.70 = 0.012 (15.00)²

b. Find y when x = 20.00.

y = 0.012 (20.00)²

y = 4.80

c. Find x when y = 7.50.

7.50 = 0.012 x²

x = 25

Answer:

2!

Step-by-step explanation:

To find out what fraction of 2 1/2 is 4/5, convert 2 1/2 to a fraction (5/2), then multiply 4/5 by the reciprocal of 5/2 which gives 8/25. So, 4/5 is 8/25 of 2 1/2.

The question is asking about what fraction of 2 1/2 is 4/5. In order to solve this, we should firstly convert the mixed number 2 1/2 to a fraction, which is 5/2. Then we have to divide 4/5 by 5/2 to find out the fraction. To divide fractions, we multiply the first fraction (the dividend) by the reciprocal of the second fraction (the divisor).

So, the problem becomes 4/5 * 2/5, and the solution is 8/25. Therefore, 4/5 is 8/25 of 2 1/2.

Answer:

53

Step-by-step explanation:

f(n) = 7n - 3

f(8) = 7*8 - 3 = 56 - 3 = 53

Final answer:

To find the 8th term of the arithmetic sequence given by f(n) = 7n - 3, substitute n with 8 and calculate the result to get 53.

Explanation:

The question is about finding the 8th term of an arithmetic sequence. The function for the sequence is given as f(n) = 7n - 3. To find the 8th term, we substitute n with 8 in the function. So, f(8) = 7(8) - 3. Calculating the value, we get f(8) = 56 - 3 = 53.

So, the 8th term of the sequence is 53. This result is obtained by applying the formula for the general term of an arithmetic sequence, where f(n) represents the term at position n. In this sequence, each term is obtained by adding 7 to the previous term.

The constant difference between successive terms (7 in this case) is a characteristic feature of an arithmetic sequence. Therefore, the 8th term of the sequence is 53.

Answer:

The closed linear form of the given sequence is [tex]a_{n}=0.75n-0.45[/tex]

Step-by-step explanation:

Given that the first term [tex]a_{1}=0.3[/tex] and [tex]a_{n+1}=a_{n}+0.75[/tex]

To find the closed linear form for the given sequence

The formula for arithmetic sequence is

[tex]a_{n}=a_{1}+(n - 1)d[/tex]  (where d is the common difference)

The above equation is of the given form  [tex]a_{n+1}=a_{n}+0.75[/tex]

Comparing this we get d=0.75

With [tex]a_{1}=0.3[/tex] and d=0.75

We can substitute these values in [tex]a_{n}=a_{1}+(n - 1)d[/tex]

[tex]a_{n}=a_{1}+(n - 1)d[/tex]

[tex]=0.3+(n-1)(0.75)[/tex]

[tex]=0.3+0.75n-0.75[/tex]

[tex]=-0.45+0.75n[/tex]

Rewritting as below

[tex]=0.75n-0.45[/tex]

Therefore [tex]a_{n}=0.75n-0.45[/tex]

Therefore the closed linear form of the given sequence is [tex]a_{n}=0.75n-0.45[/tex]

Answer:

the answer is 3

Step-by-step explanation:

Final answer:

The multiplication property of equality states that multiplying or dividing both sides of an equation by the same number does not change the equality. The reciprocal of 1/3 is 3/1 or 3. So, if you multiply or divide both sides of an equation by 3/1 (the reciprocal of 1/3), you will maintain the equality.

Explanation:

The multiplication property of equality states that multiplying or dividing both sides of an equation by the same number does not change the equality. In this case, we have the fraction 1/3. The reciprocal of 1/3 is 3/1 or 3. Multiplying both sides of an equation by 3 is equivalent to dividing both sides by 1/3. So, if you multiply or divide both sides by 3/1 (the reciprocal of 1/3), you will maintain the equality.

To calculate the area of a carpet square with sides of 9 inches, you multiply the side length by itself, resulting in an area of 81 square inches.

The question is asking for the area of a carpet square whose sides are 9 inches long. To find the area of a square, you multiply the length of one side by itself, because the formula for the area of a square is Area = side × side. In this case, each side of the carpet square is 9 inches long.

So, the area of the carpet square would be calculated as follows:

Therefore, the area of the carpet square is 81 square inches.

Answer:

[tex]3n^3(2-n^2)[/tex]

Step-by-step explanation:

Given expression:

[tex]6n^3-3n^5[/tex]

To factor out the expression completely.

Solution:

In order to factor out the expression, we will find the greatest common factor of each term.

To find the G.C.F. of the two terms, we will list down their factors and then find the common ones.

The factors of the terms can be given as:

[tex]6n^3=2\times 3\times n\times n\times n[/tex]

[tex]3n^5=3\times n\times n\times n \times n\times n[/tex]

The G.C.F. = [tex]3\times n\times n\times n=3n^3[/tex]

So, we factor out the G.C.F. and write the remaining factors inside the parenthesis.

The expression will be given using distributive property as:

⇒ [tex]3n^3(2-n^2)[/tex] (Answer)

Final answer:

To factor out [tex]6n^3 - 3n^5,[/tex] find the greatest common factor and simplify the expression.

Explanation:

A factor, in mathematics, refers to a number or algebraic expression that divides another number or expression evenly, meaning without leaving a remainder. When we say that one number is a factor of another, it means that when you divide the larger number by the factor, the result is an integer. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, because each of these numbers divides 12 without leaving a remainder.

Factoring out [tex]6n^3 - 3n^5[/tex] involves finding the greatest common factor of the terms.

Step 1: Factor out [tex]n^3[/tex] from both terms to get [tex]n^3(6 - 3n^2).[/tex]

Step 2: Further simplify to [tex]n^3(2)(3 - n^2[/tex]) for the final factored form.

Complete Question:

As you missed to add the area and length value. So, after a little research I was able to find the complete question. I will answer the question based on this complete question I am mentioning, but hopefully it would clear your concept anyways. So, here is the complete question.

The Area of a rectangular patio is 5 5/8 square yards, and it's length is 1 1/2 yards.What is the patio's width,in yards?

Answer:

The width of patios is [tex]w = \frac{15}{4} yards[/tex].

Step-by-step explanation:

As the area of a rectangular patio is [tex]A = 5\frac{5}{8}[/tex] square yards.

⇒ [tex]A = 5\frac{5}{8}[/tex]

⇒ [tex]A = 5\frac{5}{8}[/tex] can be written as : [tex]A = \frac{45}{8}[/tex]

The length of a rectangular patio is [tex]l = 1\frac{1}{2}[/tex] square yards.

⇒[tex]l = 1\frac{1}{2}[/tex]

⇒[tex]l = 1\frac{1}{2}[/tex]  can be written as : [tex]l = \frac{3}{2}[/tex]

As the area of rectangular patio can be computed by multiplying the length and width. So, width [tex](w)[/tex] can be computed by dividing the Area by length.

[tex]A = lw[/tex]

[tex]w = \frac{A}{l}[/tex]

So, [tex]w = \frac{\frac{45}{8}}{\frac{3}{2} }[/tex]

[tex]w = (\frac{45}{8}) (\frac{2}{3} )[/tex]

[tex]w = \frac{90}{24}[/tex]

[tex]w = \frac{15}{4}[/tex] or [tex]w = 3\frac{3}{4}[/tex]

Hence, the width of patios is [tex]w = \frac{15}{4} yards[/tex].

Answer:

The total payment Janie have to make is $5466 .

Step-by-step explanation:

Given as :

The loan principal = $4850

The rate of interest applied = 13.8% compounded monthly

Let The time period of loan = t years

The monthly payment she make = $455.50 each month

I.e She make payment for t years = $455.50 × n

where n is the number of terms

From Compound Interest

Amount = Principal × [tex](1+\dfrac{\textrm rate}{12\times 100})^{12\times time}[/tex]

Or,  $455.50 × n  = $4850 × [tex](1+\dfrac{\textrm 13.8}{12\times 100})^{12\times time}[/tex]

Or, [tex]\dfrac{455.50}{4850}[/tex] × n  = [tex](1.0115)^{12\times 1}[/tex]

Or, 0.0939 × n  = [tex](1.0115)^{12}[/tex]

Or, 0.0939 × n = 1.14707

∴ n = [tex]\dfrac{1.14707}{0.0939}[/tex]

I.e n = 12.21 ≈ 12

So, The number of terms Janie she will pay = 12

So, The total payment she have to make = $455.50 × 12 = $5466

Hence The total payment Janie have to make is $5466 . Answer
