Step-by-step explanation:

The equation that represent how many gallon of water are left in the tub after it ha drained for x minute is A(n) = -8x + 300.

In the given question, we have to write and equation that represent how many gallon of water are left in the tub after it ha drained for x minute.

From the given question, a hot tub that hold 300 gallon of water.

Hot tub drain at a rate of 8 gallon per minute.

So the slope will be = -8 , the negative sign is there because the water is leaving the tub.

Let the amount of water left in the tub at time n minutes is A(n) gallons.

The initial value of A(n) is 300 gallons.

Thus when n = 0, the value A(n) will be 300.

So, we can write the relation as

A(n) = -8n + 300

We need to find the amount left after x minute. So n = x

Now the equation is A(n) = -8x + 300.

The measure of arc GH is 102°.

What is inscribed angle?

In terms of geometry, an inscribed angle is the angle created when two chords intersect within a circle. It can also be described as the angle formed by two specified points on a circle at a given point on the circle. Two chords of the circle sharing an endpoint are equivalently used to define an inscribed angle.

Given:

The measure of inscribed angle ∠FHG is 39°.

We have to find the measure of arc GH.

Since,

FG = 2*m ∠FHG

FG = 2(39°)

FG = 78°

Let FH = 180°

⇒ GH = FH = FG

   GH = 180° - 78°

   GH = 102°

Hence, the measure of arc GH is 102°.

Answer: Let one of the number be X and the other no will be x +18, this is as per given sum.

By sum,

Step-by-step explanation: x + x + 18 = 128

or, 2 x = 128 - 18 = 110

Therefore x = 55 & the other no will be 55 + 18 = 73

Hence, 55 & 73 are the two numbers.

Answer:

Step-by-step explanation:

You know that it takes him 1 hour to go 17 kilometers so you can divide 54.4 by 17 to get the hours.

Step 3 is unnecessary (the statement is already given, plus you haven't proven the triangle is isosceles anyway).

After, omit step 5 and jump straight to 6.

After this, step 6 is the statement that used to be step 5, which is true by CPCTC.

Then, you can prove the required statement by definition from this.

The value of "x" in the algebraic equation

3(-3x - 8) = 3(-6x + 3) which makes it true is equal to 11/3 and option C is correct.

An algebraic equation is a mathematical statement that contains two equated algebraic expressions.

We shall evaluate for the value of x in the algebraic equation 3(-3x - 8) = 3(-6x + 3) as follows:

-9x - 24 = -18x + 9 {expand the bracket}

18x - 9x = 24 + 9 {collect like terms}

9x = 33

x = 33/9 {divide through by 9}

x = 11/3

Therefore, 11/3 is the value of x in the algebraic equation 3(-3x - 8) = 3(-6x + 3) that makes it true.

The values are calculated using the basic properties as follows.

Trigonometric functions are defined as the real functions which are simply the functions of an angle of a triangle. They are basically the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Trigonometric functions are also called as Circular functions.

Given sin θ = [tex]\frac{3}{7}[/tex] and cot θ = [tex]\frac{2\sqrt{10} }{3}[/tex]

In order to solve this, you need to know some of the basic trigonometric properties.

1. cot θ = 1 / tan θ

tan θ = sin θ / cos θ

So, cot θ = cos θ / sin θ

[tex]\frac{2\sqrt{10} }{3}[/tex] = cos θ /  [tex]\frac{3}{7}[/tex]

cos θ =  [tex]\frac{2\sqrt{10} }{3}[/tex] ×  [tex]\frac{3}{7}[/tex]

cos θ = [tex]\frac{2\sqrt{10} }{7}[/tex]

2. tan θ = 1 / cot θ

tan θ = 1 / [[tex]\frac{2\sqrt{10} }{3}[/tex]]

tan θ = [tex]\frac{3}{2\sqrt{10} }[/tex]

3. sec θ = 1 / cos θ

sec θ = 1 / [[tex]\frac{2\sqrt{10} }{7}[/tex]]

sec θ = [tex]\frac{7}{2\sqrt{10} }[/tex]

4. csc θ = 1 / sin θ

csc θ = 1 / [[tex]\frac{3}{7}[/tex]]

csc θ = [tex]\frac{7}{3}[/tex]

Answer:

Step-by-step explanation:

The total amount owed to the lender equals $2,330.

In our calculate, we are using a simple interest because it is only an interest charge that borrowers pay lenders for a loan. It is calculated by using the principal only and does not include compounding interest.

Data

Loan = $2000.00

Interest rate = 5.5%

Time = 3 years

The total amount owed:

= Loan + Interest.

To get our Interest, we will use "S.I. = PRT/100"

= 2000.00 * 5.5% * 3

= $330

Hence, the total amount owed equals to

The line of best fit to represent the given data would be y = 13.5x + 10.

What is the best-fit line in statistics?

A best-fit line, also known as a line of best fit, is a straight line that is used to model the relationship between two variables in a set of data.

A line of best fit is a straight line that is the best approximation of the data points. To find a line of best fit, you can use the method of least squares, which involves minimizing the sum of the squared differences between the data points and the line.

Given the data (x,y) = {(0,10), (1,12), (2,15), (3,20), (4,30)}, the slope of the line can be calculated using the formula:

slope = (NΣ(xy) - Σx * Σy) / (NΣ(x^2) - (Σx)^2)

Where N is the number of data points.

Plugging in the data:

slope = (5*(10+24+30+60+120) - (0+1+2+3+4)(10+12+15+20+30)) / (5(0+1+4+9+16) - (0+1+2+3+4)^2)

slope = 270/20 = 13.5

y-intercept can be calculated using the formula:

y-intercept = (Σy - slopeΣx)/N

y-intercept = (10+12+15+20+30 - 13.5(0+1+2+3+4))/5

y-intercept = 10

So, the equation of the line of best fit would be:

y = 13.5x + 10

This equation represents a line with a slope of 13.5 and a y-intercept of 10. This line of best fit can be used to make predictions about the ticket price for a given number of years since 1980.

Hence, the line of best fit to represent the given data would be y = 13.5x + 10.

The domain of the composite function is the intersection of the domain of f(x) and G(x). D f(x) intersection D g(x) The range of the function is now restricted by the domain of the composite function.

Therefore, the range is found by evaluating the function at the points in the domain of f(x).

You find the domain of the function by finding all numbers that can't go into the equation. Usually all that prevents this is whether or not it contains a fraction with x on the bottom or a x under a square root .

The range is found by finding the vertex and noting that it is the minimum or maximum (depending on direction) of the graph. You can find the vertex by using -b/2a for the x value and then plugging in to get y value.

The given function f(x) = –37 is a horizontal line which goes from negative infinity to positive infinity.

In this case, the domain can be any number since there is no limit on what the x value can be.

So, the domain of the given function f(x) = –37 will be all real numbers.

And, the range will always be y = –37 because no matter what x value will equal, y will always be equal to –37 in the function of f(x) = –37.

So, the range of the given function f(x) = –37 will be y = –37.

The equation x²+12x+43=0 is a quadratic equation that can be solved by factoring or using the quadratic formula.

Factoring the equation:

x²+12x+43=(x+7)(x+6)=0

x+7=0 or x+6=0

x=-7 and x=-6

Therefore, the solutions for the equation are x=-7 and x=-6.

Alternatively, you can use the quadratic formula:

x = (-b± √(b²-4ac))/2a

Where a=1, b=12, c=43

x = (-12± √(12²-4143))/2*1

x = (-12± √(144-172))/2

x = (-12± √(-28))/2

x = (-12± i*√28)/2

The slope of y = -9 is 0.

In mathematics, the slope of a line is a number that describes both the direction and the steepness of the line. It is commonly denoted by the letter "m".

The slope is defined as the ratio of the "rise" (change in the y-coordinate) to the "run" (change in the x-coordinate) between any two distinct points on the line. It is also known as the gradient of the line.

A line with a positive slope goes up as it goes to the right, while a line with a negative slope goes down as it goes to the right. A line with a slope of zero is horizontal, and a line with undefined slope is vertical.

The equation y = -9  is a horizontal line, hence, the slope is 0.
