By applying a rotation of 90° clockwise to square ABCD, we have the following:

A rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise direction.

In Mathematics, rotating a point 90° about the origin in a clockwise or counterclockwise direction would produce a point that has the coordinates (y, -x).

By applying a rotation of 90° clockwise to square ABCD, the coordinate of the image of square A'B'C'D' is given by:

(x, y)                           →               (y, -x)

Points at A = (-3, 5)   →  Points at A' = (5, -(3)) = (5, -3)

Points at B = (-7, -2)   →  Points at B' = ((-2), -(-7)) = (-2, 7).

Points at C = (-8, 8)   →  Points at C' = (8, -(-8)) = (8, 8).

Points at D = (-4, 10)   →  Points at D' = (10, -(-4)) = (10, 4).

Number of students need to be sampled = 610

A study to determine the true average number of alcoholic drinks consumed by Greek students is conducted.

Standard Deviation, σ = 6.3

Margin Error of population mean, E = 0.5

Probability = 95% = 0.95

The p-value corresponding to 0.95 probability = (1+0.95)/2 = 0.975

The z-score corresponding to this p-value = 1.96 [from the z-tables]

Now, The margin error, E = zσ/√n, where n is the sample size

⇒ n = (zσ/E)²

⇒ n = (1.96 x 6.3/0.5)²

⇒ n ≈ 610

Hence 610 students need to be sampled.

Number of biology book sold are 223.

Number of psychology books sold are 183.

In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities.

Given Data

A textbook store sold a combined total of 392 biology and psychology textbooks in a week. the number of psychology textbooks sold was 48 less than the number of biology textbooks sold.

Let number of biology books sold be x

Let number of psychology books sold be (x- 48)

Total book sold = 392

392 = x + x - 48

392 + 48 = 2x

446 = 2x

x = 223

The total e-waste generated over these two years in the region, expressed in scientific notation, is B. 2.49 x 10^7 tons.

Scientific notation is a standard form of expressing a short or large number in a decimal form.

Scientific notation involves writing a number that is greater than 1 but less than 10 with the power of 10.

Correct scientific notations express numbers as products of a number between 1 and 10 multiplied by an appropriate power of 10 based on its place value in the given decimal.

Thus, the total e-waste generated cannot be expressed in scientific notation as Options A, C, or D because these do not comply with the rules of scientific notations, unlike Option B.

Answer:

34.1%, D

Step-by-step explanation:

To convert a number into a percent, you multiply it by 1, or more precisely, 100%. 100% can be thought of as 100 * 1%

The correct solution to the equation is -13.

-12x + 12 = -3(5x + 8)

Split the right-hand side,

-12x + 12 = -15x + 24 (This line have error, instead of + there will be - )

Shifted the values of x to the left-hand side and the constant values to the right-hand side,

3x + 12 = 24

3x = 12

x= 4, which is the incorrect value of x.

The correct solution to the equation,

-12x + 12 = -3(5x + 8)

Split the right-hand side,

-12x + 12 = -15x - 24

Shift the values of x to the left-hand side and the constant values to the right-hand side,

3x = -36

The final value of x,

x = -13

Therefore, the value of x is -13.

Riley hit 46 balls and Paul hit 29 balls at the driving range.

According to the question, let

Number of balls hit by Riley be x

Number of balls hit by Paul be y

Together Riley and Paul hit 75 balls

∴x+y=75       (1)

Riley hit 17 more balls than Paul

∴x= y + 17      (2)

Now we have to solve these simultaneous linear equations (1) and (2)

Replacing the value of x from equation (2) into equation (1) we get,

y+17+y=75

⇒2y + 17 = 75

⇒2y = 75 - 17

⇒2y = 58

⇒y = 58/2             (dividing both sides by 2)

⇒y = 29

∴No. of balls hit by Riley = x = y +17 = 29 + 17 = 46         (from equation (2))

Therefore, Riley hit 46 balls and Paul hit 29 balls at the driving range.

Step-by-step explanation:

what I understood :

line s : y = -10x + 5/4

the slope is always the factor of x (here : -10).

a parallel lines must have the same slope.

line t : y = -10x + b

to get b we use the coordinates of the given point :

3 = -10×1 + b = -10 + b

13 = b

The number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

As given in the question,

Total gasoline with Darlene is equal to 6 3/4 gallons

Convert mixed fraction into proper fraction:

6 3/4 = 27/4 gallons

Every time amount of gasoline used to mow her lawn = 3/ 8gallon

Number of times Darlene mow her lawn before she needs more gasoline

= (27 / 4) ÷ (3 /8)

= (27 /4) × (8/3)

= 18 times

Therefore, the number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

Step-by-step explanation:

To calculate the future value we need to use the compound formula:

where P is the principal, r is the interest rate in decimal form, n is the number of times the interest is compound in any given time t.

In this case we have that P=901, r=0.035 and since the interest is compound semiannually this means that n=2. Finally t=6. Plugging this values into the equation above we have that:

Therefore the future value would be $1109.53

The answer is A because it's a non-recurring decimal.

Answer:

No

Step-by-step explanation:

Using a graph typing in 9x and looking at the table, (2,1) is not on the table, so (2,1) is not a solution to 9x

Answer:

No

Step-by-step explanation:

to determine if (2, 1 ) is a solution, substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it is a solution.

y = 9x ( substitute x = 2 )

y = 9 × 2 = 18 ≠ 1

then (2, 1 ) is not a solution to the equation.

After applying the given translation we get the function as 3x + 5

Graph translation is the process of converting an equation or existing graph into a new graph.

One common type of algebraic issue is changing algebraic equations.

A parent function's graph is altered by a translation. The three different types of translation are dilations, reflections, and translations.

A function can have its y-values modified vertically or its x-values changed horizontally (affects the x-values).

We are aware that the x- and y-coordinates must be modified to reflect the translation by the specified amount.

f( x ) = 3x is translated 5 units upwards.

Therefore the required graph is f ( x ) = 3x + 5 .
