The area of the composite figure is 186.5 m².
How to find the area of a composite figure?The figure above is a composite figure. A composite figure is a shape that has two or more shapes in it.
Hence, the area of the composite figure is the sum of the whole individuals area of the shapes.
The composite figure can be divided into rectangles, square and quarter circle.
area of the composite figure = area of rectangle + area of square + area of quarter circle
area of the composite figure = 8 × 9 + 6 × 6 + 1 / 4 × 3.14 × 10²
area of the composite figure = 72 + 36 + 1 / 4 × 3.14 × 100
area of the composite figure = 108 + 314 / 4
area of the composite figure = 108 + 78.5
area of the composite figure = 186.5 m²
Therefore, the composite figure with different shapes has an area of 186.5 metres squared.

If the degree of a polynomial function is odd and the leading coefficient is negative, then the end behavior of the function is
The end behavior of a polynomial function is to decrease without bound as x approaches negative infinity, and to increase without bound as x approaches positive infinity.
If the degree of a polynomial function is odd and the leading coefficient is negative, then the end behavior of the function is as follows:
As x approaches negative infinity, the value of the function decreases without bound.
As x approaches positive infinity, the value of the function increases without bound.
To understand why this is the case, consider a polynomial function of the form:
f(x) = a_n x^n + a_{n-1} x^{n-1} + ... + a_1 x + a_0
where n is odd and a_n < 0.
As x approaches negative infinity, the dominant term in the polynomial is a_n x^n, and since n is odd and a_n is negative, the value of the dominant term approaches negative infinity as x approaches negative infinity.
Similarly, as x approaches positive infinity, the dominant term in the polynomial is again a_n x^n, but this time the value of the dominant term approaches negative infinity as x approaches positive infinity.

The function f(x) = –5x2 + 13x + 6 represents the height, in meters, of a coin x seconds after it is thrown into the air. What is the maximum height of the coin
The maximum height of the coin is approximately 14.825 meters.
To find the maximum height of the coin, we need to find the vertex of the parabolic function. The x-coordinate of the vertex is given by:
x = -b/2a
where a = -5 and b = 13 are the coefficients of the quadratic function f(x) = -5x^2 + 13x + 6.
Plugging these values into the formula, we get:
x = -13/(2×(-5)) = 13/10
Now we can find the y-coordinate of the vertex by plugging in x = 13/10 into the function:
f(13/10) = -5(13/10)^2 + 13(13/10) + 6

The measures of the angles of a triangle are shown in the figure below. Find the measure of the largest angle.
(5x+14)°
(6x+17)°
105°
Answer:
105° is the largest angle
Step-by-step explanation:
All angles add up to 180°
Find the value of x
105 + 6x + 17 + 5x + 14 = 180
Combine like terms
136 + 11x =180
Isolate the x ( subtract 136 from both sides)
11x = 44
Divide both sides by 11
x = 4
Now substitute the value of x into each expression to find the largest angle
5(4) + 14 = 20 + 14 = 34°
6(4) + 17 = 24 + 17 = 41°
105 > 41 > 34

The volume, in cubic centimetres, of a rectangular box can be modelled by the polynomial expression 2x3−11x2−41x+140. Determine an equation to represent the area of the base of the box if the height, in centimetres, is given by 2x−5. [APP 3 marks]
The equation for area of the base of the box will be x² - 6x + 28.
What is Volume ?
In physics and mathematics, volume is a measure of the amount of three-dimensional space occupied by an object or a region. It is often measured in cubic units, such as cubic meters, cubic centimeters, or cubic feet.
The volume (V) of a rectangular box is given by the product of its length (l), width (w), and height (h):
V = lwh
Given that the volume is modelled by the polynomial expression 2x³- 11x² - 41x + 140, we can write:
V = 2x³ - 11x² - 41x + 140
And since the height is given by 2x - 5, we can substitute this expression into the formula for volume:
V = lwh = (lw)(2x - 5)
So we need to find an equation for the area of the base (lw). We can do this by rearranging the formula for volume:
lw = V / (2x - 5)
Substituting the expression for V, we get:
lw = (2x³ - 11x² - 41x + 140) / (2x - 5)
We can simplify this expression by polynomial long division or synthetic division, which gives:
lw = x² - 6x + 28
Therefore, the equation for the area of the base of the box is:
A = x² - 6x + 28, where A is the area in square centimeters, and x is the length in centimeters.

PLS HELP! I WILL MAKE U BRAINLIST! LATE WORK
Step-by-step explanation:
to graph a line always find 2 points out has to go through. that means the points' coordinates make the equation true.
I usually start with x = 0.
point 1 of equation 1 is then
y = -2×0 + 6 = 6
(0, 6)
point 1 of equation 2 is then
y = (3/2)×0 - 1 = -1
(0, -1)
then I pick a value for x that makes the handling of any fractions easier. like in our case x = 2.
point 2 of equation 1 is then
y = -2×2 + 6 = -4 + 6 = 2
(2, 2)
point 2 of equation 2 is then
y = (3/2)×2 - 1 = 3 - 1 = 2
(2, 2)
oh, so I have found the intersection point right away (point 2 of both equations).
so, let's pick a different point 2 for equation 1, like x = 4
y = -2×4 + 6 = -8 + 6 = -2
(4, -2)
with these 4 points you define the 2 lines, and you have the intersection point at (2, 2).
Mixes two varieties of saffron X and y the ratio 3:8 if the cost of X is rupees 154 per g and that of y is rupees 121 per gram at what price should he sell the mixture make a profit of 25%
The seller should sell the mixture at Rs. 162.5 per gram to make a profit of 25%.
Let's assume that the quantity of variety X in the mixture is 3x and the quantity of variety Y is 8x. Therefore, the total quantity of the mixture will be 3x + 8x = 11x.
The cost of variety X is Rs. 154 per gram. Therefore, the cost of 3x grams of variety X will be 3x × Rs. 154 = Rs. 462x.
Similarly, the cost of variety Y is Rs. 121 per gram. Therefore, the cost of 8x grams of variety Y will be 8x × Rs. 121 = Rs. 968x.
The total cost of the mixture will be the sum of the costs of the individual varieties:
Total cost = Rs. 462x + Rs. 968x = Rs. 1430x
To make a profit of 25%, the selling price of the mixture should be 1.25 times the cost price:
Selling price = 1.25 × Total cost
= 1.25 × Rs. 1430x
= Rs. 1787.5x
Therefore, the selling price of the mixture should be Rs. 1787.5x to make a profit of 25%. To find the price per gram of the mixture, we need to divide this selling price by the total quantity of the mixture:
Price per gram of mixture = Selling price / Total quantity
= Rs. 1787.5x / 11x
= Rs. 162.5 per gram (approx.)

Answer:
x²+5x+6 can be factored as (x+2)(x+3)
x²-4 can be factored as (x+2)(x-2)
x³+8 can be factored as (x+2)(x²-2x+4)
The common factor of all three expressions is (x+2). Therefore, the HCF of x²+5x+6, x²-4, and x³+8 is (x+2).
Step-by-step explanation:
Answer: To find the highest common factor (HCF) of these three polynomials, we can factor each polynomial and then look for the factors that they have in common.
First, let's factor each polynomial:
x² + 5x + 6 = (x + 2)(x + 3)
x² - 4 = (x + 2)(x - 2)
x³ + 8 = (x + 2)(x² - 2x + 4)
Now, we can see that all three polynomials have a factor of (x + 2). Therefore, the HCF of these three polynomials is (x + 2).

A population of values has a normal distribution withμ=178andσ=75.2. You intend to draw a random sample of sizen=48. Find the probability that a sample of sizen=48is randomly selected with a mean between182.3and 198.6.P(182.3×M<198.6)=Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exactz-scores orzscores rounded to 3 decimal places are accepted.
The probability that a sample of size n=48 has a mean between 182.3 and 198.6 is approximately 0.9474.
The central limit theorem: what is it?The behaviour of sample means and sums in sizable random samples is described by the central limit theorem, a statistical concept. It asserts that regardless of how the underlying population is distributed, as the sample size grows, the distribution of the sample means and sums will converge to a normal distribution. This theorem is crucial because it enables us to extrapolate population parameters from sample data. Because sample means and variances are simpler to gather and evaluate, we may use them to estimate population means, variances, and other characteristics. Several study fields, including the social sciences, the natural sciences, and business, frequently employ the central limit theorem.
Given that the sample size n = 48.
The mean between 182.3and 198.6 is calculated using the central limit theorem.
The sample mean is given as:
Z = (M - μ) / (σ / √(n))
Substituting the values we have:
Z = (198.6 - 178) / (75.2 / √(48)) - (182.3 - 178) / (75.2 / √(48))
Z = 1.62
Now, Z-score less than 1.62 is approximately 0.9474.
Hence, the probability that a sample of size n=48 has a mean between 182.3 and 198.6 is approximately 0.9474.

Tο sοlve fοr x, we can use the Pythagοrean theοrem which states that in a right triangle, the square οf the hypοtenuse (the side οppοsite the right angle) is equal tο the sum οf the squares οf the οther twο sides.
In this case, we can see that the hypοtenuse is 10 cm and οne οf the οther sides is x cm. The remaining side is then (10 - x) cm (since the triangle is isοsceles).
Applying the Pythagorean theorem, we get:
x² + (10 - x)² = 10²
x² + 100 - 20x + x² = 100
2x² - 20x = 0
2x(x - 10) = 0
So x = 0 or x = 10. However, x cannot be 0 since it would not form a triangle. Therefore, the only valid solution is x = 10.

In the given triangle the value of the ratios are Sin (P) = 5/13. tan (T) = 12 /5. cos (T) = 5/13.
What are trigonometric identities?Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are several distinctive trigonometric identities that relate a triangle's side length and angle. Only the right-angle triangle is consistent with the trigonometric identities.
The six trigonometric ratios serve as the foundation for all trigonometric identities. Sine, cosine, tangent, cosecant, secant, and cotangent are some of their names. The adjacent side, opposite side, and hypotenuse side of the right triangle are used to determine each of these trigonometric ratios. The six trigonometric ratios are the source of all fundamental trigonometric identities.
Using the trigonometric identities we can write the ratios as follows:
Sin (P) = Opposite side to P / Hypotenuse= 5/13

median = 1/2 * √(2a² + 2b² - c²)
where c is the length of the third side of the triangle. However, we don't know the length of the third side, so we need to find it. We can use the fact that the median divides the third side into two equal parts:
c/2 = (a + b)/2
c = a + b
Now we can substitute this into the formula for the length of the median:
x = 1/2 * √(2a² + 2b² - (a + b)²)
Simplifying:
x = 1/2 * √(2a² + 2b² - a² - 2ab - b²)
x = 1/2 * √(a² + 2ab + b²)
x = 1/2 * √((a + b)²)
x = 1/2 * (a + b)
x = 1/2 * (9 + 10)
x = 9
So the length of the median is 9 units.
