An equation is a mathematical statement that shows the relationship between two values, or variables. It is formed by using an equal sign between two expressions that have the same value. Equations are used to solve for unknown values, or to describe a relationship between two or more variables. Equations can be used to solve for a single variable or multiple variables, and can be used to solve problems in both mathematics and science.
To find the answer to this question we must use the formula V = L x W x H. In this case, V = 10 x 9 x 4 = 360. We now know that there is 360 cubic inches in each brick. To find the total number of bricks that can be made from 18,000 cubic inches of concrete, we must divide 18,000 by 360. The answer is 50, which means that the company can make 50 concrete bricks from 18,000 cubic inches of concrete.

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]

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%.

Step-by-step explanation: A translation of a vector is simply moving it a certain distance in a certain direction. In this case, the first translation of  <6, -4> moves the vector 6 units to the right and 4 units down. The second translation of <-3, -5> then moves the vector an additional 3 units left and 5 units down. The net result of these two translations is to move the vector 3 units to the right and 1 unit up, which is equivalent to a single translation of <3, 1>.

Answer:

To find the ordered pairs that are solutions to the equation X+2y=8, we need to isolate the variable y on one side of the equation.

We can start by subtracting X from both sides:

X+2y = 8

X+2y-X = 8-X

2y = 8-X

Now we can divide both sides by 2:

y = (8-X)/2

So the ordered pairs (X, y) that are solutions to the equation X+2y=8 are the ones that satisfy the equation y = (8-X)/2.

We can substitute any value of x into the equation and find the corresponding y value.

For example, if we take X= 4, we can find the corresponding y value:

y = (8-4)/2 = 4/2 = 2.

so (4,2) is a solution to the equation X+2y=8.

We can also plot the equation on a Cartesian plane and find the points where the equation is true, those are the solutions.

Alternatively, we can solve the equation for X and find the solutions for y.

X = 8-2y

So the ordered pairs (X, y) that are solutions to the equation X+2y=8 are the ones that satisfy the equation X = 8-2y

We can substitute any value of y into the equation and find the corresponding X value.

For example, if we take y= 2, we can find the corresponding X value:

X = 8-2(2) = 8-4 = 4.

so (4,2) is a solution to the equation X+2y=8.

In this case, any value of X and y that satisfies the equations y = (8-X)/2 or X = 8-2y are solutions to the equation X+2y=8

We can see here that the people of ages 18-29 that have tried vaping or e-cigarettes is: 25,803,450.

Population refers to the number of individuals of a particular species living in a particular area or region. In the context of human populations, it refers to the number of people living in a particular geographic area or country.

To find out the number of people ages 18-29 who said they have tried vaping or e-cigarettes, you can use the following calculation:

30,357,000 (the number of people ages 18-29) x 0.85 (the percentage of people who have tried vaping or e-cigarettes) = 25,803,450.

Every $1 decrease in price corresponds to a 0.8 increase in the number of pairs of jeans sold.

So, if [tex]x[/tex] pairs of jeans are sold, the revenue in dollars is [tex](175-x)(40+0.8x)[/tex].

The roots of this function are [tex]x=175[/tex] and [tex]x=-50[/tex]. The maximum is achieved halfway between these roots at [tex]x=62.5[/tex].

When 62.5 pairs of jeans are sold, the price is $112.50.

The store should discount the price to $112.50 to maximize its revenue

Discount is a deduction from the usual cost of something, typically given for prompt or advance payment or to a special category of buyers.

From the above question, every $1 decrease in price corresponds to a 0.8 increase in the number of pairs of jeans sold.

So, if  pairs of jeans are sold, the revenue in dollars is (175 - x)(40 + 0.8x)

The roots of this function are x = 175 and x = -50. The maximum is achieved halfway between these roots at x = 62.50.

Therefore, When 62.5 pairs of jeans are sold, the price is $112.50.

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.

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

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.
