The area of the figure is approximately 86.325 square centimeters.

A triangle is a shape with three sides and three angles. It is one of the basic shapes in geometry. Triangles can be classified according to the lengths of their sides as equilateral, isosceles and scalene triangles, and also according to their internal angles as right, acute and obtuse triangles.

To find the area of the trapezoid triangle , we need to first find the length of the other diagonal

Since the center line is perpendicular to both diagonals, it divides the trapezoid triangle into two right triangles, ABC and ABD.

Using the Pythagorean theorem, we can find the length of BD:

BD = [tex]\sqrt{(AB^2 + AD^2)}[/tex]

BD = [tex]\sqrt{(10.2^2 + 7.5^2)}[/tex]

BD = 12.654

Now, we can use the formula for the area of a trapezoid:

A = (1/2) * (AB + CD) * h

where h is the height of the trapezoid, which is the distance between the parallel sides AB and CD.

To find h, we can use the formula for the area of a triangle:

A = (1/2) * b * h

where b is the base of the triangle and h is its height.

We can use triangle ABD, which is a right triangle, to find the height h:

h = AD = 7.5

Now we can substitute the values into the formula for the area of a trapezoid:

A = (1/2) * (AB + CD) * h

A = (1/2) * (10.2 + 15.3) * 7.5

A = 86.325

Therefore, the area of the trapezoid triangle ABC is approximately 86.325 square centimeters.

Therefore, we need 7.4 ounces of rye flour and 29.6 ounces of whole-wheat flour to make a loaf of bread weighing 37 ounces, according to the recipe.

An equation is a mathematical statement that shows the equality of two expressions, usually with an equal sign "=" in between them. An equation can contain variables, constants, and operators. The variables are represented by letters and can take on different values, while constants are fixed values that do not change. Operators include mathematical symbols like plus, minus, multiplication, and division, as well as exponents and logarithms.

Here,

Let's first assign variables to represent the amounts of rye and whole-wheat flour we need to use:

Let x be the number of ounces of rye flour.

Let y be the number of ounces of whole-wheat flour.

We know from the recipe that we need to use 1 oz of rye flour for every 4 oz of whole-wheat flour. This can be expressed as:

x = y/4 (equation 1)

We also know that the total weight of the loaf of bread should be 37 oz. This means that:

x + y = 37 (equation 2)

Now we can use equation 1 to substitute for x in equation 2:

y/4 + y = 37

Multiplying both sides by 4 to eliminate the fraction, we get:

y + 4y = 148

5y = 148

y = 29.6

So we need 29.6 ounces of whole-wheat flour. Using equation 1 to find x:

x = y/4 = 29.6/4 = 7.4

No, Kiran is incorrect. -2 is actually greater than -5, so the correct statement is -5 < -2.

A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). The numbers to the left of zero are all negative whereas the numbers on the right of zero are all positive. As a result, we may argue that on a number line, the value of numbers grows as we approach towards the right. The numbers on the right are thus greater than the ones on the left, according to this statement.

Answer:

The area of the rhombus CDEF is 32 units squared.

Step-by-step explanation:

The area of the rhombus CDEF is 24 square units. This can be determined by using the formula for finding the area of a rhombus which is A = 1/2 × d1 × d2 where d1 and d2 are the lengths of the diagonals of the rhombus. In this case, d1 is the distance from C to E and d2 is the distance from D to F. Calculating the lengths of the diagonals gives d1 = 8.9 and d2 = 8. Therefore, the area of the rhombus is 24 square units.

Answer:

Bailey earned approximately $499.99 on Thursday, including his commission

Step-by-step explanation:

Bailey's earnings on Thursday consist of his base pay plus his commission. His base pay is $90, and his commission is 11% of his sales.

Let's call Bailey's sales on Thursday "S". Then his commission is 0.11S.

We know that Bailey's total earnings on Thursday were $500. So we can write an equation:

$90 + 0.11S = 500$

To solve for S, we can subtract $90$ from both sides of the equation:

$0.11S = 410$

Then we can divide both sides by $0.11$:

$S = 3,727.27$

So Bailey's sales on Thursday were $3,727.27.

To find Bailey's total earnings, we can add his base pay and commission:

$90 + 0.11(3,727.27) \approx 499.99$

So Bailey earned approximately $499.99 on Thursday, including his commission.

Step 1: Convert zeros to factors of the polynomial.

If "k" is a zero, then (x-k) is a factor of the polynomial.

The allows us to convert zeros of -3, -1, and 2 into the factors (x+3)(x+1)(x-2).

So right now we have y= (x+3)(x+1)(x-2), but there's a missing piece, the leading coefficient of "a", so really we currently have

   y = a · (x+3)(x+1)(x-2)

This is where the point (3,5) comes in.  We need to substitute x=3 and y=5 into the equation above to find a.

        5 = a · (3+3)(3+1)(3-2)

        5 = a · (6)(4)(1)

        5 = a · 24

   5/24 = a

That's the full function:

    f(x) = 5/24 (x+3)(x+1)(x-2)

Answer:

[tex]f(x)=\dfrac{5}{24}x^3+\dfrac{5}{12}x^2-\dfrac{25}{24}x-\dfrac{5}{4}[/tex]

Step-by-step explanation:

The zeros of a polynomial f(x) are the values of x which satisfy f(x) = 0.

If the polynomial function is degree 3 with 3 zeros, in factored form it can be written as f(x) = k(x - r₁)(x - r₂)(x - r₃) where r are the zeros and k ≠ 0.

Substitute the given zeros -3, -1 and 2 into the formula:

[tex]\implies f(x)=k(x-(-3))(x-(-1))(x-2)[/tex]

[tex]\implies f(x)=k(x+3)(x+1)(x-2)[/tex]

To find the value of k, substitute the given point (3, 5) into the function:

[tex]\begin{aligned}\implies f(3)&=5\\k(3+3)(3+1)(3-2)&=5\\k(6)(4)(1)&=5\\24k&=5\\k&=\dfrac{5}{24}\end{aligned}[/tex]

Therefore, the factored form of the polynomial function is:

[tex]\implies f(x)=\dfrac{5}{24}(x+3)(x+1)(x-2)[/tex]

To write in standard form, expand and distribute:

[tex]\implies f(x)=\dfrac{5}{24}(x^2+4x+3)(x-2)[/tex]

[tex]\implies f(x)=\dfrac{5}{24}(x^3+2x^2-5x-6)[/tex]

[tex]\implies f(x)=\dfrac{5}{24}x^3+\dfrac{10}{24}x^2-\dfrac{25}{24}x-\dfrac{30}{24}[/tex]

[tex]\implies f(x)=\dfrac{5}{24}x^3+\dfrac{5}{12}x^2-\dfrac{25}{24}x-\dfrac{5}{4}[/tex]

In the given problem, using central limit theorem,  the sample average score that corresponds to the 33rd percentile of all such sample averages is 100.66.

To solve this problem, we need to use the central limit theorem, which states that the distribution of sample averages is approximately normal, regardless of the distribution of the population, as long as the sample size is sufficiently large.

The mean of the sample means is equal to the population mean, which is 101. The standard deviation of the sample means, also known as the standard error of the mean, is equal to the population standard deviation divided by the square root of the sample size. In this case, the standard error of the mean is:

SE = 17 / sqrt(416) = 0.831

To find the sample average score that corresponds to the 33rd percentile of all such sample averages, we need to find the z-score that corresponds to the 33rd percentile and then use it to calculate the sample average score.

The z-score corresponding to the 33rd percentile is given by:

z = invNorm(0.33) = -0.439

where "invNorm" is the inverse normal distribution function.

We can use the formula for the z-score of a sample mean:

z = (x - μ) / SE

Rearranging this formula, we get:

x = z * SE + μ

Substituting the values we have, we get:

x = -0.439 * 0.831 + 101 = 100.66

Therefore, the sample average score that corresponds to the 33rd percentile of all such sample averages is 100.66.

The parametric equations for the curve are X = 4 sin(5t), Y = -48 sin²(5t) + 8 sin(5t) + 45

A parametric equation is a set of equations that express the coordinates of a point as functions of one or more parameters. These equations define a curve or a surface in a space and are commonly used in mathematics, physics, engineering, and computer graphics to model and analyze various phenomena.

Parametric equations can be useful in many applications, such as modeling the motion of particles, designing curves and surfaces, and creating computer animations. They also allow for the visualization of complex shapes and curves that may be difficult to describe using traditional equations.

To find the parametric equation of the given curve, we need to express the coordinates x and y in terms of a parameter t. We can use the trigonometric identities to simplify the given equations and get:

X = 4 sin(5t)

Y = -48 sin²(5t) + 8 sin(5t) - 3

Let's start with Y. We can use the identity sin²(θ) + cos²(θ) = 1 to rewrite -48 sin²(5t) as -48 (1 - cos²(5t)) = -48 cos²(5t) + 48. Substituting this into the equation for Y, we get:

Y = -48 cos²(5t) + 8 sin(5t) - 3

Now, we can use another trigonometric identity, sin²(θ) + cos²(θ) = 1, to rewrite cos²(5t) as 1 - sin²(5t). Substituting this into the equation for Y, we get:

Y = -48 (1 - sin²(5t)) + 8 sin(5t) - 3

Y = -48 sin²(5t) + 8 sin(5t) + 45

So, the parametric equations for the curve are:

X = 4 sin(5t)

Y = -48 sin²(5t) + 8 sin(5t) + 45

This is the final answer.

762 base 10 to base 7 is 2136 base 7

Base Numbers are the number of units, or numbers, we use in our counting system. The most common base number is ten because the digits 0-9 are used in the number system.

And  it is a base-7 number system we would only use seven different digits, like 0-6.

How to determine this

By dividing the number 762 base 10 in base 7 until it can no more be divided in base 7.

First divide 762 /7 = 108 remainder 6

108/7 = 15 remainder 3

15/7 = 2 remainder 1

2/7 = 0 remainder 2

Where the remainders arranged in descending is the base system.

So, by arranging from the bottom

= 2136 base 7

Therefore, 762 base 10 is 2136 base 7

Pythagorean theorem: This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be expressed as a^2 + b^2 = c^2, where a and b are the lengths of the other two sides, and c is the length of the hypotenuse.

12² + 12² = x²

288= x²

x =16.98 = 17
