There are 13 possibilities for second place, since a dog can't get both first and second place.
There are 12 possibilities for third place, since a dog can't get both first, second, and third place.
There are 11 possibilities for fourth place, since a dog can't get both first, second, third, and fourth place.

The inverse of x y is: x y x y y x x y y x

Answers

Answer:

The inverse of xy is yx.

Step-by-step explanation:

Given: xy

We need to find the inverse of xy.

To find inverse of an expression, we need to replace the variable x by y and y by x.

Given xy.

Now replace x by y and y by x, we get

Therefore, the inverse of xy is yx.

Let me show you an example.

y = x - 2

To find the inverse function, replace x by y and y by x, we get

x = y - 2

It is an equation, to write the equation in terms of y, add 2 from both sides, we get

x + 2 = y -2 + 2

x + 2 = y

Therefore, y = x + 2

A clearance rack is marked as 35% off the regular price. A shirt on the clearance rack has a regular price of $45.99. If there is 7.25% sales tax, what will the shirt ring up for at the register?
a.
$17.26
b.
$21.67
c.
$29.89
d.
$32.06

Answers

It would ring up for $32.06. To find that answer, first you would have to calculate the discount. To do so you can multiply 45.99 times .65 (100%-35%=65% which in decimal form equals .65). That gives you an answer of $29.89 BEFORE sales tax. To add the sales tax, find the decimal of the percent tax (7.25% = .0725) and add it to one (1.075) and multiply that by the clearance price (29.89X1.075). That gives you a final answer of $32.06. Hope this helps!

The shirt ring-up at the register will be $32.06. Then the correct option is D.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Percentage (P) = [Final value - Initial value] / Initial value x 100

A clearance rack is marked as 35% off the regular price. A shirt on the clearance rack has a regular price of $45.99. If there is a 7.25% sales tax.

The shirt ring up for at the register will be given as,

Lima is constructing a square in which two of its vertices are points A and B. He has already used his straightedge and compass to construct the lines and arcs shown.

Answers

The location above point b, label as point C. That distance is the span at which the compass should stay. I am presuming that is is the same distance from A to B in which two sides of the square are consructed. Keeping the span the same, place the point of the compass on point C and create an arc in the vacinity of the third vertex of the square. Repeat this process with the point of the compass on point A without changing the span of the compass. Where the arcs intersect, label point D. Use the straight edge to draw in AD and CD. The square is completed.

A new hybrid car has a 18-gallon gas tank. On one tank of gas, the owner can drive 540 miles. The number of miles traveled varies directly with the number of gallons of gas the car uses.

a. Write an equation that relates the number of miles traveled with the number of gallons of gas used.

b. How many miles can the owner travel on 12 gallons of gas?

Answers

To find the amount of miles/gallon, we have 540 miles/18 gallons=30 miles/gallon. As we add 30 miles for every gallon, the amount of miles traveled is 30*x (e.g. if x is 1 then 0+30=30 and if x is 2 then 30+30 (2 times)=60) with x being the amount of gallons. For b, we just plug 12 in for x to get 20*12=360

Write the equation for the vertical line that contains point E (10,-3)

Answers

A vertical line is known as undefined and goes straight up and down.

This means it eventually crosses the x axis.

Undefined equations are represented by x= (wherever it crosses the x axis)

So since this point is (10 , -3), it crosses the x axis at 10 and goes up and down forever.

The equation of the line is x = 10.

Answer:

The growth factor is '2'

Step-by-step explanation:

Here, the given function that represents the population of the rabbits that is increasing exponentially,

[tex]f(x)=5(2)^t----(1)[/tex]

Since, the growth factor is a multiplier that increases the value per period,

Also, in an exponential growth function,

Since, in function (1) t is a variable ( time in months )

By comparing, b = 2,

2) option J

That is the application of Pythagorean theorem, which applys for right triangles.

3) Use sine ratio

sin (30°) = opposite-leg / hypotenuse

=> opposite-leg = hypotenuse * sin(30°)

opposite-leg = f(h)

hypotenuse = h

sin(30°) = 1/2

=> f(h) = h * 1/2

5) The slope - y -intercept function of the line is y = mx + b where m is the slope and b is the y-intercept.

In this problem m = c and b = d

6) Use the formula speed = distance / time => time = distance / speed

=> f(x) = x / m < ------ option J

7) Use the equation of the distance

distance^2 = (x - x1)^2 + (y - y1)^2

given y = 2x + 7 and (x1,y1) = (3,0)

=> distance^2 = (x - 3)^2 + ( 2x + 7 - 0)^2

=> distance^2 = (x - 3)^2 + (2x + 7)^2

=> f(x) = √ [ (x - 3)2 + (2x + 7)^2 ] <------- option D

Your business borrowed 10 bitcoins on May 1, when 1 bitcoin was worth $1,418.86. On June 1, 1 bitcoin was worth $2,441.29. Not counting the 1 month of interest, what is the total amount, including the principal, your business owed on June 1, in dollars?

Answers

Final answer:

The business owed a total of $24,464.43, including the principal, on June 1.

Explanation:

To calculate the total amount your business owed on June 1, we need to find the value of the borrowed bitcoins in dollars on that date.

Step 1: Convert the number of borrowed bitcoins to dollars on May 1 by multiplying it by the value of 1 bitcoin in dollars: 10 bitcoins * $1,418.86/bitcoin = $14,188.6.

Step 2: Convert the value on May 1 to the value on June 1 by multiplying it by the change in the value of 1 bitcoin:

$14,188.6 * ($2,441.29/$1,418.86)

= $24,464.43.

Therefore, your business owed a total of $24,464.43, including the principal, on June 1.

The total amount owed on June 1, not counting the 1 month of interest, is $24,412.90.

To calculate the total amount owed on June 1, we need to multiply the number of bitcoins borrowed by the value of one bitcoin on that date.

On May 1, the business borrowed 10 bitcoins, and the value of one bitcoin on June 1 was $2,441.29. Therefore, the total amount owed on June 1, excluding interest, is calculated as follows:

Number of bitcoins borrowed = 10

Value of one bitcoin on June 1 = $2,441.29

Total amount owed on June 1 (in dollars) = Total amount owed on June 1 (in dollars) = [tex]10 \times $2,441.29[/tex]

Total amount owed on June 1 (in dollars) = $24,412.90

Thus, the total amount owed on June 1, not counting the 1 month of interest, is $24,412.90.

Which figure shows how a shape can be rotated about an axis to form a cone?
A. Triangle

Answers

Check out the attached image to see the answer. It is the answer choice with the right triangle (with 90 degree angle) laying on top of the axis. It is NOT the first triangle shown as we won't get a cone in that case. It will be a sort of spinning top.

The figure that shows how a shape can be rotated about an axis to form a cone is (d) right triangle

How to determine the figure?

The shapes are given as:

A. Triangle

B. Circle

C.Square

D. right triangle

Rotating a circle about its axis would form a sphere, while a square would be rotated to form a cylinder.

However, when a right triangle is rotated, it forms a cone

Hence, the figure is (d) right triangle

Find equations in standard form of the lines through point P that are A.) parallel to, and B.) perpendicular to, line L. P(0,-4); L: 2y=x. I've tried solving it and looking at examples, but no examples in my book are like this problem.

Answers

2y = x
y = 1/2x....the slope of this line is 1/2.

A parallel line will have the same slope.
y = mx + b
slope(m) = 1/2
(0,-4)....x = 0 and y = -4
now we sub and find b, the y int
-4 = 1/2(0) + b
-4 = b
so ur equation is : y = 1/2x - 4...but we need it in standard form Ax + By = C

y = 1/2x - 4....subtract 1/2x from both sides
-1/2x + y = -4...multiply both sides by -2
x - 2y = 8 <== standard form of parallel line
==========================
the slope of the line was 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular line will have a slope of -2...see how I flipped 1/2 making it 2/1...and changed the sign, making it -2.

y = mx + b
slope(m) = -2
(0,-4)...x = 0 and y = -4
sub and find b
-4 = -2(0) + b
-4 = b
so this equation is : y = -2x - 4....but we need standard form

y = -2x - 4....add 2x to both sides
2x + y = -4 <== standard form of perpendicular line
