Answer:

length = 17;  breadth = 9

Step-by-step explanation:

Let x = area of rectangle; a = length; b = breadth.

+)       a × b = x (1)

+)      (a - 5) × (b + 3) = x - 9 => x = ab + 3a - 5b - 15 + 9 (2)

+)      (a + 3) × (b + 2) = x + 67 => x = ab + 2a + 3b + 6 - 67 (3)

Replace (1) into (2) & (3):

The correct direction and angle of rotation between triangle ABC in quadrant 4 and polygon A' B' C' in quadrant 3 is: 90° clockwise rotation.

A transformation in geometry is a procedure that modifies the location, scale, or orientation of a shape. Translations, rotations, reflections, and dilations are examples of common transformations.

Rotations are transformations that involve rotating a shape around a fixed point called the center of rotation. The direction of rotation can be either clockwise or counterclockwise, and the angle of rotation is the amount of rotation in degrees.

A' is located to the left of A, which indicates a clockwise rotation.

B' is located below B, which also indicates a clockwise rotation.

C' is located to the right of C, which indicates a clockwise rotation as well.

The correct response is a 90° clockwise rotation since all of the relevant vertices of polygon A' B' C' are turned clockwise in relation to triangle ABC. I regret if the prior replies left you perplexed.

The intersection points in the function is (-4, 61)

To find the intersection points of two functions, we can set them equal to each other and solve for x. Substituting x = -4, we have:

4(-4)² + 3(-4) + 3 = (-4)³ + 7(-4)² - 3(-4) + d

Simplifying, we get:

64 - 12 + 3 = -64 + 112 + 12 + d

d = -77

So the two functions intersect at x = -4 and y = 61. Therefore, the only intersection point is (-4, 61).

What are fractions?

A fraction is a mathematical representation of a quantity that expresses a part of a whole or a ratio between two quantities.

To find the total fraction of the diagram that is shaded, we need to add the fractions representing the shaded areas of the two squares.

Given that one square is shaded 2/12 and the other shaded square is 2/15, we can add these fractions:

2/12 + 2/15

To add fractions, we need to find a common denominator. The least common multiple (LCM) of 12 and 15 is 60, so we can use 60 as the common denominator for both fractions:

(2/12) + (2/15) = (2/12) * (5/5) + (2/15) * (4/4)

= 10/60 + 8/60

Now we can add the numerators:

= (10 + 8)/60

= 18/60

= 3/10

So, the total fraction of the diagram that is shaded is 3/10.

Hence, the correct answer is C. 0.3, which is equivalent to 3/10.

The radius of the circle is 12, and the equation of the circle is:

(x + 2)² + (y - 8)² = 144

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

To find the equation of a circle that is tangent to a horizontal line at a given point, we can use the standard form of the equation of a circle:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

In this case, the center of the circle is (-2, 8), which gives us:

(x + 2)² + (y - 8)² = r²

To find the radius, we need to know where the circle intersects the y = -4 line. Since the circle is tangent to the line, the distance from the center of the circle to the line is equal to the radius.

The distance between a point (x, y) and a horizontal line y = k is given by |y - k|.

In this case, the distance between the center (-2, 8) and the line y = -4 is |8 - (-4)| = 12.

Therefore, the radius of the circle is 12, and the equation of the circle is:

(x + 2)² + (y - 8)² = 144

Complete question:

What is the center at (-2, 8), tangent to the line y = -4?

Answer: To find the derivative of the function h(x), we can use the quotient rule, which states that if f(x) = u(x) / v(x), then f'(x) = [v(x)u'(x) - u(x)v'(x)] / [v(x)]^2.

Using this rule, we can find the derivative of h(x) as follows:

h(x) = (x + 2) / (x - 2)

h'(x) = [(x - 2)(1) - (x + 2)(1)] / (x - 2)^2 // apply the quotient rule and differentiate numerator and denominator

h'(x) = (-2 - 2x) / (x - 2)^2

Therefore, the derivative of h(x) is h'(x) = (-2 - 2x) / (x - 2)^2.

Step-by-step explanation:

We can label the point (75, 50) as the optimal solution for the banquet, as it represents the maximum number of guests that can be invited while staying within the constraints.

What is banquet?

A banquet is a large formal meal that usually involves multiple courses and is served to a group of people on special occasions such as weddings, awards ceremonies, or fundraising events. Banquets often include speeches, presentations, and entertainment, and are typically held in a large venue such as a hotel ballroom, banquet hall, or conference center. Banquets can be hosted for a variety of purposes, such as to honor a special guest, celebrate an achievement, or raise money for a charitable cause.

To create a graph showing the solution region of the system of inequalities representing the constraints of the situation, we can use custom relationships to define the variables and constraints.

Let's define the variables:

Let x be the number of adult guests.

Let y be the number of student guests.

Now, let's write the system of inequalities representing the constraints of the situation:

The total number of guests cannot exceed 125: x + y ≤ 125

The cost of hosting the banquet cannot exceed $3375: 45x + 15y ≤ 3375

To graph this system of inequalities, we can plot the boundary lines of each inequality and shade the region that satisfies all the constraints.

The boundary lines of each inequality are:

x + y = 125 (the line that connects the points (0, 125) and (125, 0))

45x + 15y = 3375 (the line that connects the points (0, 225) and (75, 0))

To find the viable combinations of guests that satisfy all the constraints, we need to shade the region that is below the line x + y = 125 and to the left of the line 45x + 15y = 3375.

The resulting graph should look like this:

The point where the two lines intersect, (75, 50), represents the maximum number of adult guests (75) and the maximum number of student guests (50) that can be invited to the banquet while staying within the budget and venue capacity. Any point within the shaded region represents a viable combination of guests.

We can label the point (75, 50) as the optimal solution for the banquet, as it represents the maximum number of guests that can be invited while staying within the constraints.

Answer:  there are 13 rows of seats in the theater.

Step-by-step explanation: Concurring to the issue, the number of lines is 3 less than the number of seats in each push. So, the number of lines can be communicated as "x - 3".

We know that the theater can situate 208 individuals, so the entire number of seats can be communicated as "x times (x - 3)".

Hence, we are able type in the condition as:

x(x - 3) = 208

Expanding the condition, we get:

x^2 - 3x - 208 =

Presently, ready to unravel this quadratic condition to discover the esteem of "x" which speaks to the number of seats in each push:

Utilizing the quadratic equation:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = -3, and c = -208

x = (-(-3) ± sqrt((-3)^2 - 4(1)(-208))) / 2(1)

x = (3 ± sqrt(841)) / 2

x = (3 ± 29) / 2

Ready to disregard the negative arrangement, so:

x = (3 + 29) / 2

x = 16

Hence, the number of seats in each push is 16.

And, the number of columns can be communicated as "x - 3":

Number of columns = 16 - 3 = 13

Okay, let's walk through this step-by-step:

The initial balance of the savings account: $312.50

The final balance after 9 years: $1250

Let's call the interest rate r.

We know the final balance is the initial balance times (1 + r)^9

(because of continuous compounding over 9 years)

So:

312.50 = (1 + r)^9

312.50 / (1 + r)^9 = 1250

Solving for r:

(312.50 / 1250)^(1/9) = 1 + r

0.2504 = 1 + r

0.7596 = r

Converting to a percentage:

0.7596 * 100% = 75.96%

Rounding to the nearest whole percent: 76%

So the interest rate is 76%.

Answer:

no, 3/4 is bigger because 3/5 is cut into more pieces then 3/4

Step-by-step explanation:

There would be $2,085 in the account after 12 years.

The formula for calculating the amount of money in an account after a certain number of years with continuous compounding is:

A = Pe^(rt)

Where

In this case, Julian invested $990 at an annual interest rate of 6.2% compounded continuously, which means r = 0.062. We want to find the amount of money in the account after 12 years, so t = 12. Using these values, we can plug into the formula and solve for A:

A = Pe^(rt)

A = $990 * e^(0.062*12)

A = $990 * e^(0.744)

A = $990 * 2.105

A = $2,084.95

The area of the figure is 51 cm², which is option C.

In mathematics, area refers to the measure of the size of a two-dimensional surface or shape. It is typically expressed in square units, such as square meters (m²) or square centimeters (cm²), and can be calculated for a variety of geometric shapes, including squares, rectangles, triangles, circles, and more complex shapes such as trapezoids or polygons.

To find the area of the figure, we need to identify the shape of the figure. From the given information, we know that the figure has a top side, a height, and a base. We are also told that the base is divided into two parts by a perpendicular, and one of the parts is labeled as 4 cm, while the other part from the perpendicular to the right vertex is 6.2 cm.

Based on this information, we can draw the figure as a trapezoid, where the top side is the shorter base, the height is the vertical distance between the two bases, and the longer base is the sum of the two parts of the base.

Using the given information, we can calculate the longer base:

longer base = 4 cm + 6.2 cm = 10.2 cm

Now we can use the formula for the area of a trapezoid to find the area of the figure:

A = (1/2)h(b₁ + b₂)

where h is the height, b₁ is the shorter base, and b₂ is the longer base.

Plugging in the given values, we get:

The probability of both rolls being more than 4 is 0.25, written to two decimal places.

Probability is the measure of how likely it is that a certain event will occur. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. Probability is calculated by taking the number of outcomes that are favorable to the event divided by the total number of possible outcomes.

Let X1 be the outcome of the first roll and X2 be the outcome of the second roll.
We want the probability that X1 > 4 and X2 > 4.
Since each of the 6 outcomes are equally likely and the two rolls are independent of each other, we can calculate the probability as the product of the probabilities of each event.
The probability of X1 > 4 is 3/6, and the probability of X2 > 4 is also 3/6.
Therefore, the probability that both rolls are more than 4 is:
P(X1 > 4 and X2 > 4) = (3/6) * (3/6) = 0.25
