On solving the provided question we can say that by percentage y = $1900(77/100)t

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

In 2005, a laptop computer was purchased for 81900. Each year since, the resale value has decreased by 23%. Let t be the number of years since Let Y be the value of the laptop computer, in dollars. Write an exponential function showing the relationship between Y and

Therefore , The negative linear equation result indicates that the coffee shop made $56 less from hot coffee drinks than from iced coffee drinks yesterday.

A straightforward regression graph is created using the equation y=mx+b. The y-intercept is m, and the slope is B. Despite the fact that the line before it contains independent parts, it is repeatedly alluded to as a "mathematical formula combining many factors." Only two factors are present in bivariate linear equations. There are no known solutions to application issues concerning linear equations. Y=mx+b.

Here,

Let H be the number of hot coffee drinks sold yesterday, and I be the number of iced coffee drinks sold yesterday. We know that:

H + I = 100 (since a total of 100 cups were sold)

We also know that the average price of a hot coffee drink was $3.50 and the average price of an iced coffee drink was $2.00. Therefore, the total revenue from hot coffee drinks is:

3.50H

And the total revenue from iced coffee drinks is:

2.00I

To find the difference in revenue between the hot and iced coffee drinks sold yesterday, we need to subtract the revenue from iced coffee drinks from the revenue from hot coffee drinks:

3.50H - 2.00I

We want this expression to equal zero, so we can set it equal to zero and solve for H:

3.50H - 2.00I = 0

3.50H = 2.00I

H = (2/3.50)I

H ≈ 0.57I

Since H + I = 100, we can substitute 0.57I for H in the equation:

0.57I + I = 100

1.57I = 100

I ≈ 63.7

Rounding to the nearest whole number, we get:

I = 64

Therefore, H = 100 - I = 36

So the difference in revenue between the hot and iced coffee drinks sold yesterday is:

3.50H - 2.00I = 3.50(36) - 2.00(64) = $72 - $128 = -$56

The negative result indicates that the coffee shop made $56 less from hot coffee drinks than from iced coffee drinks yesterday.

The given assertion states that the length of BD in its simplest radical version is 7/√2.

A triangle is indeed a 3-sided shape that is occasionally (though not frequently) referred to as the trigon. There are three edges and three angles in every triangle, some of which could be the same.

Since BD is an altitude of the right triangle ABC, we can use the Pythagorean Theorem to find the length of BD. First, let's determine the size of AC:

AC² = AD * DC = 7 * 5 = 35

When we square the two edges, we obtain:

AC = √35

Now, we can use the fact that BD is an altitude to write:

BD = (AC * AD) / hypotenuse

where hypotenuse is the length of BC.

Using the Pythagorean Theorem, we can find the length of BC:

BC² = AC² + AB²

Since triangle ABC is a right triangle, we have AB = BC, so we can write:

BC² = AC² + BC²

Simplifying, we get:

BC² / AC² = 2

When we square the two edges, we obtain:

BC / AC = √2

Multiplying both sides by AC, we get:

BC = AC * √2 = √35 * √2 = √70

Now, we can substitute the values of AC, AD, and BC into the formula for BD:

BD = (AC * AD) / BC = (√35 * 7) / √70 = 7 / √2

Therefore, the length of BD in simplest radical form is 7 / √2.

The derivative of a composite function is given by the chain rule: the fifth derivative of fog(x) depends only on the second and fourth derivatives of f.

d(fog(x))/dx = df/d(g(x)) * d(g(x))/dx

The fifth derivative of fog(x) can be calculated by taking the derivative five times:

d^5(fog(x))/dx^5 = d^5f/d(g(x))^5 * (dg(x)/dx)^5 + 5 * d^4f/d(g(x))^4 * d^2g(x)/dx^2 * (dg(x)/dx)^3 + 10 * d^3f/d(g(x))^3 * (dg(x)/dx)^2 * (d^2g(x)/dx^2)^2 + 10 * d^2f/d(g(x))^2 * (dg(x)/dx) * (d^3g(x)/dx^3) + 5 * df/d(g(x)) * (d^4g(x)/dx^4)

Since g'(x) is constant, dg(x)/dx is also constant, and its derivative is 0. Therefore, all the terms with derivatives of g(x) higher than 1 are 0, leaving us with:

d^5(fog(x))/dx^5 = 5 * d^2f/d(g(x))^2 * (dg(x)/dx)^2 * d^2g(x)/dx^2 + 5 * df/d(g(x)) * d^4g(x)/dx^4

Since g'(x) is constant, dg(x)/dx and d^2g(x)/dx^2 are also constant, and can be replaced by their values. Therefore, the fifth derivative of fog(x) depends only on the second and fourth derivatives of f.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that scores on a standardized test are normally distributed with a mean of 105 and standard deviation of 15.

We need to find the test score is 1.2 standard deviations above the mean

1.2 standard deviations is 1.2×15 =18

So 105-18=87

87 is the score that is 1.2 standard deviations from the mean.

The area of the lawn in the Wilson family's back yard is 4400 square feet.

The Wilson family's back yard is a rectangular plot that has a length of 100 feet and a width of 80 feet.

Let us assume that A₁ be the area of the reactangular plot.

Using the formula for the area of rectangle,

A₁ = 100 × 80

A₁ = 8000 sq. ft.

The family planted a garden with a length and width of 60 feet.

This means, the shape of the garden must be square.

Using the formula for the area of square,

A₂ = 60 × 60

A₂ = 3600 sq. ft.

The family planted a lawn in the remaining area of the back yard, as shown.

Let us assume that A represents the area of the lawn in the Wilson family's back yard.

Answer: x = 4

Step-by-step explanation:

Translating the problem into mathematical terms:

Let's call the number x. Then the problem can be written as:

5 * (2x - 3) - (x + 8) = 13

Expanding the left side of the equation:

5 * 2x - 5 * 3 - x - 8 = 13

Simplifying the left side of the equation:

10x - 23 - x - 8 = 13

Combining like terms:

9x - 31 = 13

Adding 31 to both sides of the equation:

9x = 44

Dividing both sides of the equation by 9:

x = 4.88888...

Since x has to be a whole number, we round down to the nearest whole number:

x = 4

Therefore, the number that satisfies the equation is 4.

The answer of the questions:

a) The surface is an ellipsoid,

(b) If the equation is changed to x² - y² + z² = 4, the graph is still an ellipsoid, and

(c) If the equation is changed to x² + y² + 2y - z² = 3, the graph is not an ellipsoid anymore,

What is an ellipsoid?

An Ellipsoid is a closed surface on which all plane cross sections are either ellipses or circles. An ellipsoid is symmetrical about three mutually perpendicular axes that intersect at the center.

(a)

x = k:

Trace: Circle in the x-z plane

Identification: Circle

y = k:

Trace: Circle in the y-z plane

Identification: Circle

z = k:

Trace: Circle in the x-y plane

Identification: Circle

The surface is an ellipsoid, which is a 3-dimensional surface that is the result of stretching or compressing a sphere along different axes.

(b)

If the equation is changed to x² - y² + z² = 4, the graph is still an ellipsoid, but it is rotated so that its axis is the x-axis.

(c)

If the equation is changed to x² + y² + 2y - z² = 3, the graph is not an ellipsoid anymore, and its shape cannot be determined from the equation alone.

This is because the equation contains a linear term (2y) that makes it non-quadratic.

To find the shape of the surface, a more in-depth analysis would be required.

Hence, the answer of the questions:

a) The surface is an ellipsoid,

(b) If the equation is changed to x² - y² + z² = 4, the graph is still an ellipsoid, and

(c) If the equation is changed to x² + y² + 2y - z² = 3, the graph is not an ellipsoid anymore,

The number of coins in the bag = 50 coins

The number of pennies = 12 % of coins

So , the number of pennies = ( 12/100 ) x 50 = 6 pennies

The number of dimes in the bag = 44 % of the coins

The number of dimes in the bag = ( 44/100 ) x 50 = 22 dimes

The number of nickels = 8 + number of pennies = 8 + 6

The number of nickels = 14 nickels

The remaining number of coins are quarters

On simplifying the equation , we get

So , the number of quarters = 50 - 6 - 22 - 14 = 8 quarters

And , the value of 6 pennies = $ 0.06

The value of 22 dimes = $ 0.22

The value of 14 nickels = $ 0.70

The value of 8 quarters = $ 2.00

Therefore , the total amount in the bag = $ 2.00 + $ 0.70 + $ 0.22 + $ 0.06
