figure is 9 square units. Draw unit squares to
cover this figure.

The given relationship is such that 1 / z⁴ = z ⁻⁴.

When given 1 / z⁴, this can be rewritten in such a way that it becomes z ⁻⁴.

This is because when a denominator is raised to a exponent , it can be transformed to a numerator if the sign on the power is changed to the negative.

This means that when the fraction was 1 / z⁴, it can become the value of z ⁻⁴ because the negative in front of the 4 shows that it is a fraction.

The correct answer is d.  The standard form of the equation of f(x) is −x2 + 6x + 16.

A downward opening parabola is a curve in the shape of a parabola that opens downward and is symmetrical about the x-axis. The equation of a downward opening parabola is y = ax^2 + bx + c, where a is a negative number, and b and c are constants.

The focus of a downward opening parabola is the point on the parabola where the curvature is greatest and is located at the vertex of the parabola.

The directrix of a downward opening parabola is a line parallel to the x-axis and the distance from the focus to the directrix is equal to the length of the latus rectum of the parabola. The equation of the directrix is y = -a(x - h)^2 + k, where h and k are constants.

Downward opening parabolas can be used to graphically represent any type of data that follows a parabolic shape. This includes physical phenomena such as the path of a projectile or the vibration of a string.

Downward opening parabolas can also be used to model economic or financial data, such as the demand for a product or the price of a commodity. They may also be used to describe relationships between two variables in a mathematical equation.

The standard form of a parabola equation is f(x) = ax2 + bx + c, where a, b, and c are real numbers. In this case, the vertex of the parabola is at (3, 25), so the equation is in the form f(x) = a(x - 3)2 + 25. Putting in the other points on the graph to solve for a, b, and c yields the equation f(x) = -x2 + 6x + 16.

Step-by-step explanation:

what is missing is the definition that QS is the height and therefore standing at a right angle (90°) at PR.

then this can be solved.

we use Pythagoras

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.

let's start with the triangle PQS.

21² = 15² + QS²

441 = 225 + QS²

QS² = 216

QS = sqrt(216) = sqrt(36×6) = 6×sqrt(6) = 14.69693846...

now for triangle QSR

(5x - 16)² = (3x - 4)² + QS²

25x² - 160x + 256 = 9x² - 24x + 16 + 216

16x² - 136x + 24 = 0

2x² - 17x + 3 = 0

the solution to a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (17 ± sqrt(17² - 4×2×3))/(2×2) =

= (17 ± sqrt(289 - 24))/4 = (17 ± sqrt(265))/4

x1 = (17 + 16.2788206...)/4 = 8.319705149...

x2 = (17 - 16.2788206...)/4 = 0.180294851...

but using x2 in side lengths 3x - 4 or 5x - 16 gives us negative side lengths. that does not make any sense for actual side lengths.

so, x1 is our solution :

x = 8.319705149...

The margin of error, given the percentage who replied that Newton ate the apple, is 3.5%.

The margin of error is a measure of how much the sample results are likely to vary from the true population value.

To calculate the margin of error, you need to know the sample size, the proportion of the sample that gave a particular response, and the level of confidence.

The formula for the margin of error is:

Margin of Error = z x √(p x ( 1 - p) / n)

where:

z = the critical value from the standard normal distribution table

p = the proportion of the sample that gave a particular response

n = the sample size

The margin of error for Newton eating the apple is therefore:

Margin of Error = 1.96 x √(0.28 x (1 - 0.28) / 581)

Margin of Error = 1.96 * √(0.00035)

Margin of Error = 1.96 * 0.018

Margin of Error = 0.035

The margin of error is therefore 3.5%.

Answer:

y = 5.25 [tex](8)^{x}[/tex]

Step-by-step explanation:

the general form of an exponential function is

y = a [tex](b)^{x}[/tex]

to find a and b , substitute the coordinates of the given points into the equation.

using (2, 336 )

336 = a b² → (1)

using (3, 2688 )

2688 = a b³ → (2)

divide (2) by (1)

[tex]\frac{ab^3}{ab^2}[/tex] = [tex]\frac{2688}{336}[/tex] ( cancel ab on numerator/denominator of left side )

b = 8

substitute b = 8 into (1) and solve for a

336 = a × 8² = 64a ( divide both sides by 64 )

5.25 = a

then exponential function is

y = 5.25 [tex](8)^{x}[/tex]

To add or subtract fractions, they must have a common denominator. In this case, the denominators of the fractions are 2 and 8, which are not the same. To find the least common multiple of 2 and 8, we can list the multiples of each number and find the smallest one that is common to both:

2: 2, 4, 6, 8, 10, 12, 14, ...

8: 8, 16, 24, 32, ...

The least common multiple of 2 and 8 is 8. Therefore, to add or subtract the fractions, we must convert them to have a denominator of 8.

-3/2 = -12/8 and 3/8 = 3/8

So, -3/2 - 3/8 = -12/8 - 3/8

Now we can subtract the fractions directly:

-12/8 - 3/8 = -12 - 3 / 8

= -15/8

Therefore, the simplified form of -3/2 - 3/8 is -15/8

The terms mean median, mode, and range describe properties of statistical distributions.

The statistical distributions' characteristics are described by the terms mean, median, mode, and range. The set of all potential values for terms that indicate predetermined events is known as a distribution in statistics. A term's value stated as a variable is referred to as a random variable.

The two main categories of statistical distributions are as follows. There are discrete random variables in the first category. This indicates that each phrase has a distinct, precise numerical value. A continuous random variable is present in the distribution of the second major kind. An unlimited number of possible values can be represented by a continuous random variable. A term is said to have a probability density function when any value can be assigned to it within an uninterrupted interval or span.

Trapezoid PQRS having vertices P(0, 0), Q(0, 4), R(6, 4), and S(12, 0),

has the length of the midsegment as 11.07 units.

What is a trapezoid?

A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.

The length of the mid segment of trapezoid is half the sum of the lengths of the two parallel sides, PQ and RS.

The points for vertices are given as - P(0, 0), Q(0, 4), R(6, 4), and S(12, 0).

Length of sides PQ and RS is given as -

The line segment PQ = √(x2 - x1)² + (y2 - y1)²

PQ = √(0 - 0)² + (4 - 0)²

PQ = √0² + (4)²

PQ = √0 + 16

PQ = √16

PQ = 4 units

The line segment RS = √(x2 - x1)² + (y2 - y1)²

RS = √(12 - 6)² + (0 - 4)²

RS = √(6)² + (-4)²

RS = √36 + 16

RS = √50

RS = 5√2 units

To find the mid segment add the length of PQ and RS.

So, the equation will be -

Midsegment = PQ + RS

Midsegment = 4 + 5√2

Midsegment = 11.07 units

Therefore, the length of midsegment is 11.07 units.

If f(x) = x⁴ + 2, g(x) = x-6 and h(x) = √x , then the simplified form of f(g(h(x))) is f(g(h(x))) = (√x - 6)⁴ + 2.

What is the polynomial expression?

Any expression which consists of variables, constants, and exponents, and is combined using mathematical operators like addition, subtraction, multiplication, and division is a polynomial expression.

We can simplify f(g(h(x))) by first evaluating h(x), then substituting the result into g(x), and finally substituting the result into f(x).

Starting with h(x) = √x, we can substitute this into g(x) to get:

g(h(x)) = g(√x) = √x - 6

Next, we can substitute g(h(x)) = √x - 6 into f(x) to get:

f(g(h(x))) = f(√x - 6) = (√x - 6)⁴ + 2

Simplifying this expression requires some algebraic manipulation, but we can expand (√x - 6)⁴ using the binomial theorem or by using the method of FOIL (first, outer, inner, last) repeatedly. Either way, we will end up with a polynomial expression in x with terms of various degrees.

Therefore, the simplified form of f(g(h(x))) is f(g(h(x))) = (√x - 6)⁴ + 2.
