BRAINLIEST PLEASEEEE HELP DUE IN 3hrs Can someone help me with this

Answer:

The correct option is;

d. Reflecting about the line y = -1, followed by translating 8 units to the right

Step-by-step explanation:

The coordinates of the vertices of the banner Jane created = A(-4, 3), B(-1, 5) and C(-1, 2)

By reflecting across the line y = -1, we get

A(-4, 3) by reflection across the line y = -1 gives A(-4, -5)

B(-1, 5) by reflection across the line y = -1 gives B(-1, -7)

C(-1, 2) by reflection across the line y = -1 gives C(-1, -4)

By translating 8 units to the right get

A(-4, 3) by translation 8 units right gives A prime (4, -5)

B(-1, 5) by translation 8 units right gives B prime (7, -7)

C(-1, 2) by translation 8 units right gives C prime (7, -4)

Therefore, the two transformation that she could perform so that the transformed vertices become A prime (4, -5), B prime (7, -7), and C prime (7, -4) are;

1) Reflection across the line y = -1

2) An horizontal translation 8 units to the right get.

Transformation involves changing the size and position of a shape.

The sequence of two transformations are: (d). reflecting about the line y = -1, followed by translating 8 units to the right

The coordinates of ABC are given as:

\(\mathbf{A =(-4,3)}\)

\(\mathbf{B =(-1,5)}\)

\(\mathbf{C =(-1,2)}\)

First, the coordinates of ABC are reflected across the line \(\mathbf{y =-1}\)

The transformation rule is:

\(\mathbf{(x,y) \to (x,-y -2 \times 1)}\)

So, we have:

\(\mathbf{A' = (-4,-3 -2 \times 1)}\)

\(\mathbf{A' = (-4,-5)}\)

\(\mathbf{B' =(-1,-5 - 2 \times 1)}\)

\(\mathbf{B' =(-1,-7)}\)

\(\mathbf{C' =(-1,-2 -2 \times 1)}\)

\(\mathbf{C' =(-1,-4)}\)

Next, the shape is translated 8 units right.

The rule of this transformation is:

\(\mathbf{(x,y) \to (x + 8, y)}\)

So, we have:

\(\mathbf{A" = (-4 + 8, -5)}\)

\(\mathbf{A" = (4, -5)}\)

\(\mathbf{B" =(-1+8,-7)}\)

\(\mathbf{B" =(7,-7)}\)

\(\mathbf{C" =(-1+8,-4)}\)

\(\mathbf{C" =(7,-4)}\)

Hence, the sequence of two transformations are:

Step-by-step explanation:

The floor area of the engineer's model of the sugar factory is 10.825 square feet.

To determine the floor area of the engineer's model of a sugar factory in square feet, we need to convert the given measurements from inches to feet. Since there are 12 inches in a foot, we can divide both dimensions by 12 to convert them.

The length of the model in feet is 30 inches / 12 = 2.5 feet, and the width is 52 inches / 12 = 4.33 feet.

To find the floor area, we multiply the length by the width:

Area = Length × Width

= 2.5 feet × 4.33 feet

= 10.825 square feet

It's important to note that the given measurements are not a standard aspect ratio or scale for a sugar factory. The given dimensions may be scaled down for the model's convenience, so the calculated floor area is only applicable to the scale of the model.

In actuality, a sugar factory would have much larger dimensions.

To find the area of the shaded polygon, we had to assume that each dotted line was one unit. In which case, the coordinates are:

Hence, the area of the polygon is A \(\approx\) 11.15 units.

To get the area of the polygon, we must determine the length of all it's sides.

a) A-B is given by the distance formula:

distance = √((x2 - x1)² + (y2 - y1)²)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using this formula, we can calculate the distance between points A(1,4) and B(5,6) as follows:

distance = √((5 - 1)² + (6 - 4)²)

= √(16 + 4)

= √(20)
A-B = 4.47213595

A-B \(\approx\) 4.47

b)
To find B-C we use the same method:
B-C = 3.16 units.

c)
To find C- D we use the same method:
C- D  \(\approx\) 3.16 units.

d) to find D-A  we use the employ the same method:
D - A \(\approx\) 2.83



Since this is an irregular quadrilateral, we will require the use of the
length of one of it's diagonals which is also computed using the distance formula to get: 4.47 Units.

The measure of side KL is 65.4 to the nearest tenth.

If the side on one form is a and the side on the other form is b, then there will be a common ratio r between the two forms, such that a = b x r. Simply divide the length of one comparable side by the other to arrive at a similar ratio, r = a / b.

We have the quadrilaterals, GHIJ is similar to KLMN.

That means, the common ratio is constant.

To find the common ratio:

Side of GHIJ / Side of KLMN = k (let),

here we choose similar sides.

Substituting the value of sides to the formula,

48 / 11 = k

k = 4.363636

So, the length of KL = k x similar side of GHIJ

The length of KL = 4.363636 x 15

The length of KL = 65.4

Therefore, side KL = 65.4.

The number of tractors lent by the first, second and third stations results in a system of three simultaneous equations which indicates;

The first originally station had 39 tractors, the second station had 21 tractors and the third station originally had 12 tractors

Simultaneous equations are a set of two or more equations that have common variables.

Let x represent the number of tractors at the first station, let y represent the number of tractors at the second tractor station, and let z, represent the number of tractors at the third tractor station

According to the details in the question, after the first transaction, we get

Number of tractors at the first station = x - y - z

Number of tractors at the second station = y + y = 2·y

Number of tractors at the third station = z + z = 2·z

After the second transaction, we get;

Number of tractors at the first station = 2·x - 2·y - 2·z

Number of tractors at the second station = 2·y - (x - y - z) - 2·z = 3·y - x - z

Number of tractors at the third station = 2·z + 2·z = 4·z

After the third transaction, we get;

Number of tractors at the first station = 2 × (2·x - 2·y - 2·z) = 4·x - 4·y - 4·z

Number of tractors at the second tractor station = 6·y - 2·x - 2·z

Number of tractors at the third tractor station = 4·z - (2·x - 2·y - 2·z) - (3·y - x - z) = 7·z - x - y

The three equations after the third transaction are therefore;
4·x - 4·y - 4·z = 24...(1)

6·y - 2·x - 2·z = 24...(2)

7·z - x - y = 24...(3)

Multiplying equation (2) by 2 and subtracting equation (1) from the result we get;

12·y - 4·x - 4·z - (4·x - 4·y - 4·z) = 16·y - 8·x = 48 - 24 = 24

16·y - 8·x = 24...(4)

Multiplying equation (3) by 2 and multiplying equation (2) by 7, then adding both results, we get;

14·z - 2·x - 2·y = 48

42·y - 14·x - 14·z = 168

42·y - 14·x - 14·z + (14·z - 2·x - 2·y) = 48 + 168

40·y - 16·x = 216...(5)

Multiplying equation (4) by 2 and then subtracting the result from equation (5), we get;

40·y - 16·x - (32·y - 16·x) = 216 - 48 = 168

8·y = 168

y = 168/8 = 21

The number of tractors initially at the second station, y = 21

16·y - 8·x = 24, therefore, 16 × 21 - 8·x = 24

8·x = 16 × 21 - 24 = 312

x = 312 ÷ 8 = 39

The number of tractors initially at the first station, x = 39

7·z - x - y = 24, therefore, 7·z - 39 - 21 = 24

7·z = 24 + 39 + 21 = 84

z = 84/7 = 12

The number of tractors initially at the third station, z = 12

Step-by-step explanation:

The theoretical probability of Nadir being chosen as part of the group of four students for the student council is 4/6, which simplifies to 2/3.

To calculate the theoretical probability, we need to determine the number of favorable outcomes (Nadir being chosen) and divide it by the total number of possible outcomes (all combinations of four students out of the six).

First, let's calculate the number of favorable outcomes. Since we want Nadir to be chosen, we can consider Nadir as one of the positions to be filled. This leaves us with three remaining positions to be filled by the remaining five students (Michelle, Olivia, Parvi, Quinn, and Richard). Therefore, the number of favorable outcomes is the number of ways to choose three students out of the five, which is given by the combination formula: 5 choose 3 = 5! / (3! * (5-3)!) = 10.

Next, let's determine the total number of possible outcomes, which is the number of ways to choose four students out of the six. Using the combination formula again, we have 6 choose 4 = 6! / (4! * (6-4)!) = 15.

Finally, we divide the number of favorable outcomes by the total number of possible outcomes: 10 / 15 = 2/3. Therefore, the theoretical probability of Nadir being chosen as part of the group is 2/3.

By using the product and quotient rules of logarithms, we can simplify this expression as follows

2 loga( 4) + 3 loga( X-4) - log a(4)

= loga(4 ²) + loga((X-4)³) -  loga (4) = loga (16 ) + loga((X-4)³) - loga (4)

Combining the logarithms  using the power rule and quotient rule we have

log(x+3) + log (x-3)

By using the product rule of logarithms, we can combine these logarithms

log (x +3) +log (x - 3) = log ((x +3 )(x -3 ))

Step-by-step explanation:

Simple interest is a method for calculating the percentage of interest paid on a sum over a predetermined time period at a predetermined rate. The annual simple interest rate on the principal amount of 10000 at the end of 7 years would be 3%.

In simple interest, the principal amount doesn't change. Simple interest is a clear-cut and simple method for figuring out how much money has earned interest. It is a way to figure out how much interest will be charged.

Simple interest can be computed by multiplying the principal amount by the rate multiplied by the time period. In banks and other financial institutions, simple interest is frequently used to complete a variety of calculations. The total amount of cash that was spent on interest during the course of the loan is described.

Simple Interest = ( Principal × Rate × Time ) / 100

First, we need the Simple Interest (S.I)

Total = Principal + Simple Interest

T = P + S.I

$10,000 = $12,100. + S.I

S.I = $12,100 - $10,000

S.I = 2100

Simple Interest = (Principal × Rate × Time) / 100

S.I = (P × R × T) / 100

2100 = (10000 × R × 7) / 100

2100 = 70000R / 100

2100 = 700R

R = 2100 / 700

R = 3

a) the solutions to the equation sin(2x) = cos(x) over [0, 2π] are x = π/6, π/2, 5π/6, and 3π/2., b) The simplified expression for (f(x) - f(a))/(x - a) is -(a - x)/(ax).

a. To solve the equation sin(2x) = cos(x) over the interval [0, 2π], we can use trigonometric identities and algebraic manipulations. Let's begin:

sin(2x) = cos(x)

Using the double angle formula for sine, we have:

2sin(x)cos(x) = cos(x)

Rearranging the equation, we get:

2sin(x)cos(x) - cos(x) = 0

Factoring out the common term cos(x), we have:

cos(x)(2sin(x) - 1) = 0

Now we can set each factor equal to zero:

cos(x) = 0   or   2sin(x) - 1 = 0

For cos(x) = 0, the solutions over [0, 2π] are x = π/2 and x = 3π/2.

For 2sin(x) - 1 = 0, we have:

2sin(x) = 1

sin(x) = 1/2

The solutions for sin(x) = 1/2 over [0, 2π] are x = π/6 and x = 5π/6.

b. To find and simplify (f(x) - f(a))/(x - a), where f(x) = -4/x + 3, we'll substitute the values into the expression and simplify:

(f(x) - f(a))/(x - a) = (-4/x + 3 - (-4/a + 3))/(x - a)

To simplify further, we can find a common denominator for -4/x and -4/a:

(-4/a + 3a/a - (-4/x + 3x/x))/(x - a)

= (-4a + 3a - (-4x + 3x))/(ax)

= (-a + x)/(ax)

= -(a - x)/(ax)

Using the formula of area of a circle, about 226.08in² has been eaten

The diameter of the pizza is given as 24 inches. To calculate the area of the entire pizza, we need to use the formula for the area of a circle:

Area = π * r²

where π is approximately 3.14 and r is the radius of the circle.

Given that the diameter is 24 inches, the radius (r) would be half of the diameter, which is 12 inches.

Let's calculate the area of the entire pizza first:

Area = 3.14 * 12²

Area = 3.14 * 144

Area ≈ 452.16 square inches

Now, if half of the pizza is consumed, we need to calculate the area of half of the pizza. To do that, we divide the area of the entire pizza by 2:

Area of half of the pizza = 452.16 / 2

Area of half of the pizza ≈ 226.08 square inches

Therefore, if half of the pizza is consumed, approximately 226.08 square inches of pizza would be eaten.
