R₀, 270° is the rule that describes the transformation

Rotation simply means turning. In a cartesian plane, if a point P, whose position vector is (x,y), is rotated through θ° about the origin, the position of the image P' is

a. (-y, x) for θ = 90°

b. (-x, -y) for θ = 180°

c. (y, -x) for θ = 270°

Given the: Triangle RST with vertices R(2, 0), S(4, 0), and T(1, -3). And the image of triangle RST after a rotation has vertices R'(0, -2). S'(0, -4), and T(-3, -1)

From the given vertices it is obvious that the relation between preimage and image is defined as

(x, y) => (y, -x)

Therefore, the rule that describes the transformation is (y, -x) for θ = 270° (i.e. when the figure rotates 270° counterclockwise). So the third option (R₀, 270° ) is the answer.

Answer:

$370.62

Step-by-step explanation:

Ken spends $344.76 before tax at a hardware store. If the sales tax rate in his city is 7.5%, what is the total cost of his purchase? Round to the nearest cent if necessary.

7.5% = 0.075

0.075 * $344.76  = $25.857 in tax so:

cost + tax

$344.76 + $25.857 = $370.617

rounded:  $370.62

The area of a square with a side length √8 represents a rational number, which is equal to 8 square units.

Rational numbers are real numbers of the form m / n, where m and n are integers, where n ≠ 0. The rest of real numbers are irrational (i.e. π, √5, ∛7, e) Besides, the area of the square is determined by the following formula:

A = l²

Where l is the side length of the square.

First, substitute the side length of the square in the area formula:

A = (√8)²

Second, use algebraic properties to simplify the expression and find the corresponding result:

A = ([tex]8^{\frac{1}{2} }[/tex])²

A = 8

This number represents a rational number as 8 is equivalent to the rational number 8 / 1.

The solution of the absolute value equation |3x - 6| = 12 is x= 6 and x = -2

The absolute value equation is

|3x - 6| = 12

We can write the absolute value equation in two ways

3x - 6 = 12

-(3x - 6) = 12

We have to solve each equation

The first equation is 3x - 6 = 12

3x - 6 = 12

3x = 12+6

3x = 18

x = 18/3

x = 6

The second equation is -(3x - 6) = 12

Apply the distributive property

-3x + 6 = 12

-3x = 12 - 6

-3x = 6

x = 6/-3

x = -2

Hence, the solution of the absolute value equation |3x - 6| = 12 is x= 6 and x = -2

Step-by-step explanation:

1. Let x = the amount of money invested at 5%, and y = the amount of money invested at 8%.

   x + y = 30,000 (the total amount invested)

   0.05x + 0.08y = 2,100 (the total interest earned)

2. Solve the system by whatever method you choose.

The value of (2/3) ÷ (1/4) is 8/3 and the value of 7 ÷ (2/3) is 21/2.

This is a question from the division of fractions.

We know the property of fractions is given by:-

(m/n) ÷ (a/b) = (m/n)*(b/a) = mb/na

Hence, we can write,

(2/3) ÷ (1/4) = (2/3) * (4/1) = 2*4/3*1 = 8/3

7 ÷ (2/3) = (7/1)*(3/2) = 7*3/ 1*2 = 21/2

Answer:

Step-by-step explanation:

You have tickets that sell for $25 and $15, and you sold 55 tickets for $1025. You want to know the number of each sold.

Let 'a' represent the number of advance tickets sold. Then 55-a is the number of same-day tickets sold. The total revenue is ...

  25a +15(55 -a) = 1025

  10a + 825 = 1025 . . . . . simplify

  10a = 200 . . . . . . . . . . subtract 825

  a = 20 . . . . . . . . . . . divide by 10; the number of advance tickets

  55 -20 = 35 . . . . the number of same-day tickets

20 advance tickets and 35 same-day tickets were sold.

The correct option regarding the price is C. no; The packs of socks are marked up to $7 and then discounted to $4.20.

In this situation, a shoe store buys packs of socks wholesale for $5 each and marks them up by 40%. The price will be:

= Original price + Markup

= 5 + (40% × 5)

= 5 + 2

= $7

Then, the store decides to discount the packs of socks by 40%. This will give a price of:

= 7 - (40% × 7)

= 7 - 2.8

= $4.2

The price isn't discounted to $5.

Zeros of polynomial are the points where the polynomial equals zero on the whole. In simple words, we can say that zeros of polynomial are values of the variable such that the polynomial equals 0 at that point. Zeros of a polynomial are also referred to as the roots of the equation and are often designated as α, β, γ respectively.

The zeros of a polynomial f(x) are the values of x which satisfy the equation f(x) = 0. Here f(x) is a function of x, and the zeros of the polynomial are the values of x for which the f(x) value is equal to zero. The number of zeros of a polynomial depends on the degree of the equation f(x) = 0. All such domain values of the function, for which the range is equal to zero, are called the zeros of the polynomial.

To find the zeros of this polynomial function, we have to write the function appropriately.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. In addition to being expressed in percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.

The incidence rate is = 0.2%  or 0.002

The false negative rate is = 8%  or 0.008

The false positive rate is = 1%  or 0.001

The probability is
