The square root of 104 is approximately 10.198039, which can be confirmed using a calculator. It’s not a perfect square, so rounding it to 10.2 is often sufficient for practical purposes.

To find the square root of 104, we will use a calculator since it's not a perfect square. The square root of 104 is approximately 10.198039.

Here’s a step-by-step approach:

The exact value includes more decimal places, so for most purposes, you can round it to an appropriate value, such as 10.2 for simplicity.

The answer is:

The correct option is the first option,

[tex]y=\frac{5}{4} (x-1)[/tex]

To solve this problem, we need to remember that the point-slope form of a line is given by the following equation:

[tex]y-y_{1}=m(x-x_{1})\\\\y-0=\frac{5}{4}(x-1)[/tex]

We are given two points of the line,

[tex](5,5)\\(1,0)[/tex]

Where,

[tex]x=5\\x_{1}=1\\y=5\\y_{1}=0\\[/tex]

Then, substituting the given points into the equation ,to calculate m (slope), we have:

[tex]m=\frac{y-y_{1}}{x-x_{1}}[/tex]

[tex]m=\frac{5-0}{5-1}=\frac{5}{4}[/tex]

The slope of the function is [tex]\frac{5}{4}[/tex]

Now, substituting "x1" and "y1" and the slope in the point-slope equation, we have:

[tex](y-0)=\frac{5}{4} (x-1)[/tex]

[tex]y=\frac{5}{4} (x-1)[/tex]

Hence, the correct option is the first option,

[tex]y=\frac{5}{4} (x-1)[/tex]

Have a nice day!

Answer:

The correct answer is first option

y = 5/4(x - 1)

Step-by-step explanation:

It is given two coordinates (5, 5) and (1, 0)

To find the slope

Slope = (y₂ - y₁)/(x₂- x₁)

slope = (5 - 0)/(5 - 1) = 5/4

To find the equation

(y - y₁)/(x - x₁) = 5/4

(y - 0)/(x - 1) = 5/4

y = 5/4(x - 1)

The correct answer is first option

Have a nice day.

The average pay for Tim Worker's second job income monthly is $232.50.

To calculate the average, first, sum up all the monthly incomes:

200 + 150 + 250 + 260 + 285 + 380 + 200 + 225 + 200 + 250 + 220 + 150 = $2970

Next, divide the total income by the number of months (12 in this case) to find the average:

2970 / 12 = $232.50

So, the average monthly income from Tim Worker's second job is $232.50.

To find the average income, you add up all the monthly incomes and then divide by the total number of months. In this case, adding up Tim Worker's monthly incomes gives us $2970. Then, dividing by 12 (the number of months) gives us the average monthly income of $232.50. This method ensures that each month's income contributes equally to the overall average, regardless of fluctuations in individual months. So, despite variations in Tim Worker's monthly income, the average remains consistent at $232.50 per month.

Answer:

22x + 99

Step-by-step explanation:

Given

9(2x + 9) + 2(2x +9) ← factor out (2x + 9) from each term

= (2x + 9)(9 + 2)

= 11(2x + 9) ← distribute parenthesis

= 22x + 99

Here's two ways you can solve this exercise: you can expand the multiplications and sum like terms:

[tex]9(2x+9)+2(2x+9) = 18x+81+4x+18 = 22x+99[/tex]

Or you can factor the parenthesis:

[tex]9(2x+9)+2(2x+9) = (2x+9)(9+2) = 11(2x+9) = 22x+99[/tex]

Answer:

[tex](x + 3) {}^{2} - 16[/tex]

Step-by-step explanation:

[tex] {x}^{2} + 6x - 7 = (x + 3) {}^{2} - (3) {}^{2} - 7 \\ = (x + 3) {}^{2} - 16[/tex]

The equation x^2 + 6x - 7 can be written in the form (x+a)^2 + b as (x + 3)^2 - 16 by completing the square.

To solve this, we will complete the square for the polynomial x^2 + 6x - 7. The equation (x+a)^2 + b involves squaring a binomial (x+a) and adding a constant. Completing the square can convert x^2 + 6x - 7 to this form.

Step 1: Half of the coefficient of x is (6/2)=3 so a=3. Then we square a to get a^2 = 9.

Step 2: We adjust the original equation by subtracting and adding a^2 within it: (x^2 + 6x + 9) - 9 - 7.

Step 3: Simplify the equation to get (x + 3)^2 - 16, which is the form we desired.

Answer:

20x - 8

Step-by-step explanation:

using the distributive property to simplify (5x-2)4, you would multiply the outside term (4) by each inside term (5x-2).

for example:

4 × 5x = 20x

4 × -2 = -8

once you distribute the 4 into 5x-2, you are left with 20x - 8 which needs no further simplifying

Answer:

Step-by-step explanation:

The distributive property: a(b + c) = ab + ac

(5x - 2) · 4 = 4(5x - 2) = (4)(5x) + (4)(-2) = 20x - 8

For this case we must find the inverse of the following function:

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

We follow the steps below:

Replace f(x) with y:

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

We exchange the variables:

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

We solve for "y":

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

Multiply by -2 on both sides of the equation:

[tex]\sqrt {y + 3} = - 2x[/tex]

We raise both sides of the equation to the square to eliminate the radical:

[tex](\sqrt {y + 3}) ^ 2 = (- 2x) ^ 2\\y + 3 = 4x ^ 2[/tex]

We subtract 3 from both sides of the equation:

[tex]y = 4x ^ 2-3[/tex]

We change y by f ^ {- 1} (x):

[tex]f ^ {- 1} (x) = 4x ^ 2-3[/tex]

Answer:[tex]f ^ {- 1} (x) = 4x ^ 2-3[/tex]

Answer:

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

Step-by-step explanation:

Given : [tex]f(x) =-\frac{1}{2}\sqrt{x+3}[/tex].

To find : Find the inverse of the given function.

Solution : We have given

[tex]f(x) =-\frac{1}{2}\sqrt{x+3}[/tex].

Step 1: take f(x) = y

[tex]y =-\frac{1}{2}\sqrt{x+3}[/tex].

Step 2 : Inter change y and x.

[tex]x =-\frac{1}{2}\sqrt{y+3}[/tex].

Step 3 : Solve for y

Taking square both sides

[tex]x^{2} = \frac{1}{4}(y+3)[/tex].

On multiply both sides by 4.

[tex]4x^{2} = (y+3)[/tex].

On subtraction both sides by 3.

[tex]4x^{2} -3 = y[/tex].

Here, [tex]f(x)^{-1}= y[/tex] is inverse of f(x)

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

Therefore, [tex]f(x)^{-1}= 4x^{2} -3 [/tex] .

Answer:

He has 11 quarters

Step-by-step explanation:

* Lets study the information in the problem to solve it

- The value of dimes and quarters is $6.35

- There are dimes and quarters

- The dime = 10 cents

- The quarter = 25 cents

* We must change the money from dollars to cents

∵ $1 = 100 cents

∴ $6.35 = 6.35 × 100 = 635 cents

- The number of dimes = 3 + 3 × number of quarters

* Let number of dimes is D and number of quarter is Q

∴ D = 3 + 3Q

∴ 10D + 25Q = 635

* Substitute the value of D from first equation in the second equation

∴ 10(3 + 3Q) + 25Q = 635 ⇒ open the bracket

∴ 10(3) + 10(3Q) + 25Q = 635

∴ 30 + 30Q + 25Q = 635 ⇒ collect like terms

∴ 30 + 55Q = 635 ⇒ subtract 30 from both sides

∴ 55Q = 605 ⇒ divide both sides by 55

∴ Q = 11

* He has 11 quarters

Answer:

y = 3x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 9 ← is in slope- intercept form

with slope m = 3

• Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (2, - 2) into the partial equation

- 2 = 6 + c ⇒ c = - 2 - 6 = - 8

y = 3x - 8 ← equation of parallel line

Answer:

y=15

Step-by-step explanation:

The formula for direct variation is

y = kx

5 =k*2

Solve for k

Divide by 2

5/2 = k

y = 5/2 x

Now we substitute x=6

y = 5/2(6)

y = 15

Answer:

y = 15

Step-by-step explanation:

If the variables are directly proportional, increasing one by a factor of 3 will mean the other one also increases by a factor of 3.

6 is 3 times 2, so the value of y will be 3 times 5, or 15.

___

You can write the relation as a proportion:

y/x = 5/2 = ?/6

Multiplying by 6 gives ...

(5/2)·6 = ? = 15

___

Or, you can bother with an equation relating x and y:

y = kx

5 = k·2 . . . plug in the given values and solve for k

5/2 = k . . . divide by 2

Then ...

y = (5/2)·6 = 15 . . . . same as the proportion, above.

If you rearrange this to y = 5·(6/2) then you see the relation described at the beginning of this solution. The new value of y is the old value multiplied by the factor by which x changes.

Answer:

B

Step-by-step explanation:

The range is the set of y-values for which the function is defined.

** Attached is the graph of the function

By looking at the graph, we can clearly see that there aren't any y-values that is not permitted in the graph. The function is defined for all y-values. Hence the range is set of all real numbers, or, the range is (-∞, +∞)

Answer choice B is right.

Final answer:

The range of the reciprocal function 1/x is all real numbers except zero, expressed in interval notation as (-∞, 0) ∪ (0, +∞).

Explanation:

The range of the reciprocal function, which is denoted as 1/x, can be understood by considering the behavior of the function as x approaches different values. As x approaches zero from the positive side (x → 0+), the reciprocal 1/x becomes increasingly larger, theoretically 'going to infinity' (∞). Similarly, as x approaches zero from the negative side (x → 0-), 1/x becomes increasingly negative, 'going to negative infinity' (-∞). Thus, the range of the reciprocal function excludes zero, but includes all other real numbers. In interval notation, the range is expressed as (-∞, 0) ∪ (0, +∞).

Answer:

Option D. [tex]\$6,139.25[/tex]

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=4\ years\\ P=\$5,350\\ r=0.035\\n=1[/tex]  

substitute in the formula above  

[tex]A=\$5,350(1+\frac{0.035}{1})^{1*4}[/tex]

[tex]A=\$5,350(1.035)^{4}=\$6,139.25[/tex]

Final answer:

The future amount of money in the account after 4 years with annual compound interest is approximately $6,139.25, which is option D.

Explanation:

The student's question pertains to the calculation of compound interest over a period of 4 years on a principal amount at a given interest rate. To calculate compound interest, we use the formula A = P(1 + r)^n, where A is the total amount after n periods, P is the principal amount, r is the annual interest rate (as a decimal), and n is the number of years the money is compounded. Applying this formula:

P = $5,350 (the principal amount)

r = 0.035 (since 3.5% as a decimal is 0.035)

n = 4 (compounding for 4 years)

Using the formula:

A = $5,350(1 + 0.035)^4

A = $5,350(1.035)^4

A = $5,350 * 1.14888281

A ≈ $6,139.25

Thus, the amount of money in the account at the end of 4 years, with compound interest, will be approximately $6,139.25, which corresponds to option D.

It was given that: the volume is 2,279.64 in³

The height of the cylinder is also given as: h=18 in.

We substitute, the given values into the formula to get:

[tex]2279.64= \frac{1}{3} \times (3.14) \times {r}^{2} \times 18[/tex]

[tex]2279.64= 18.84 {r}^{2} [/tex]

[tex] {r}^{2} = \frac{2279.64}{18.84} [/tex]

[tex] {r}^{2} = 121[/tex]

We take positive square root to get;

[tex]r = \sqrt{121} [/tex]

[tex]r = 11in[/tex]

Therefore the diameter is 2(11) which is equal to 22 inches.

8.99 rounded to 1 decimal place is 9.0, since the number after the decimal is 9, which is 5 or over, hence, the rounding up.

In mathematics, rounding means to replace a number with an approximate value that has a shorter, simpler, or more explicit representation. To round the number 8.99 to 1 decimal place, you need to look at the second number after the decimal point. Since that number is 9, which is 5 or over, we round up the first number after the decimal point, which is 8. Thus, 8.99 rounded to 1 decimal place is 9.0.

We can observe that whatever point we choose for R, one of the equal sides will be either PR or QR because points P and Q share the same x-coordinate (2).

Considering the coordinates of P (2, 7) and Q (2, -3), the vertical distance between P and Q is 10 units. For triangle PQR to be isosceles, the distance from R to either P or Q needs to be the same. This means point R must be horizontally aligned with P and Q to maintain its x-coordinate as 2, while the y-coordinate must be equidistant from P and Q's y-coordinates.

Since point P's y-coordinate is 7, and Q's is -3, the y-coordinate of R must be the average of 7 and -3, which is (7 + (-3))/2 = 2.

Therefore, the coordinates of R should be (2, 2), making triangle PQR isosceles with PR and QR as the equal sides. However, none of the given options (I, II, III) have an x-coordinate of 2, so none of these points could form an isosceles triangle with P and Q according to the given coordinates.
