you can multiply the two bases together and then raise the product to the sum of the exponents.

When you have two exponential expressions with different bases and want to multiply them together, you cannot directly multiply the bases together.

An exponent is a mathematical notation that indicates the number of times a number, variable, or expression is multiplied by itself. It is usually written as a superscript to the right of the base number, as in "[tex]a^b[/tex]", where "a" is the base and "b" is the exponent.

The exponent "b" tells us how many times the base "a" should be multiplied by itself. For example, in the expression 2c, the base is 2, and the exponent is 3. This means that we need to multiply 2 by itself three times, resulting in 2 × 2 × 2 = 8.

The ramp will rise 20.79 inches from the ground at its highest end.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's assume that the ramp will be in the shape of a right triangle, where the length of the base (the horizontal distance from the ground to the highest end of the ramp) is 36 inches and the angle between the base and the hypotenuse (the ramp itself) is 30 degrees.

We can use trigonometry to find the height of the ramp (the vertical distance from the ground to the highest end of the ramp).

First, we need to find the length of the hypotenuse. We can use the formula:

hypotenuse = base / cosine(angle)

In this case, the base is 36 inches and the angle is 30 degrees, so:

hypotenuse = 36 / cosine(30) = 41.57 inches (rounded to the nearest hundredth)

Next, we can use the formula for the sine of an angle:

sine(angle) = opposite / hypotenuse

In this case, the opposite side (the height of the ramp) is what we want to find. So we can rearrange the formula to solve for the height:

height = sine(angle) x hypotenuse

Plugging in the values we know, we get:

height = sine(30) x 41.57 = 20.79 inches (rounded to the nearest hundredth)

Therefore, the ramp will rise 20.79 inches from the ground at its highest end.

In response to the query, we can state that Hence, 2x + 3y = -4 is the equation equation of the line in standard form.

An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

y - y1 = m(x - x1) (x - x1)

where m is the slope of the line and (x1, y1) is one of the line's points.

With the two provided locations, we can first determine the slope of the line:

m = (y2 - y1)/(x2 - x1) = (-2 - 2)/(1 - (-5)) = -4/6 = -2/3

Let's utilise the point-slope form with one of the given points, (-5, 2):

y - 2 = (-2/3)(x - (-5))

y - 2 = (-2/3)x - 10/3

When we multiply both sides by 3, we obtain:

3y - 6 = -2x - 10

2x + 3y = -4

Hence, 2x + 3y = -4 is the equation of the line in standard form.

Given a starting point of (-4, 3), if move 2 units up and 6 units right, you will end up at the point (2,5).

A point in a coordinate system has two coordinates - an x-coordinate and a y-coordinate.

The x-coordinate tells you how far to move horizontally from the origin (0,0), and the y-coordinate tells you how far to move vertically from the origin.

Given the point (-4,3) means that you start at the point that is 4 units to the left of the origin and 3 units above the origin.

Now, moving 2 units up from (-4,3), you will end up at the point that is 2 units higher on the y-axis.

So, your new y-coordinate will be 3 + 2 = 5.

When you move 6 units right from (-4,3), you will end up at the point that is 6 units to the right on the x-axis.

So, your new x-coordinate will be -4 + 6 = 2.

Therefore, you end up at the point (2,5).

The distribution of severity ratings across reports can also be calculated by counting the number of reports with each severity rating.

The statistic that cannot be calculated from the table of reports is the average duration of the feeling.

This is because the table only provides information about the date, time, description, and severity of the feeling, but not the duration.

To calculate the average duration, one would need to take the difference between the time of the first report and the time of the last report for each user.

This information is not provided in the table.

However, other statistics can be calculated from the table of reports.

For example, the user id with the most number of reports can be calculated by counting the number of reports for each user and identifying the user with the highest count.

Using the given information, the guitar is less expensive at Store A

It is less expensive by $16

From the question, we are to determine where the guitar is less expensive.

A. Store A offers a discount of 75%. Therefore, the price of the guitar at Store A after the discount is:

Price at Store A = Original price * (1 - Discount percentage)

Price at Store A = $160 * (1 - 0.75)

Price at Store A = $40

Thus, the guitar is $40 at Store A after the discount.

B. Store B offers a discount of 50% off the original price, followed by an additional 30% off in all discounted prices. This means that the price of the guitar at Store B after the two discounts is:

Price at Store B = Original price * (1 - First discount percentage) * (1 - Second discount percentage)

Price at Store B = $160 * (1 - 0.5) * (1 - 0.3)

Price at Store B = $160 * 0.5 * 0.7

Price at Store B = $56

Thus, the guitar is $56 at Store B after the two discounts.

There are no middle planes for a given tetrahedron. This is because a tetrahedron is a three-dimensional figure with four faces, each of which is a triangle. Each of the four vertices of a tetrahedron is equidistant from one of the faces, but not from any of the other three faces. Therefore, there are no planes that are equidistant from all four vertices of a tetrahedron.

To further explain, let's consider the four distances from the vertices A, B, C, and D to a plane P. If all four distances are the same, then the plane P must be equidistant from all four vertices. However, this is not possible in a tetrahedron because each vertex is closer to one face than it is to the other three faces. Therefore, there are no middle planes in a tetrahedron.

How does diameter work?

the distance that a straight line must travel in order to connect two points on opposite edges of a circular object or shape The diameter is twice as large as the radius. The pond's circumference is six feet.

Since the circle's centre is on the y-axis, its x-coordinate is zero. Moreover, the circle's radius is 6 units because its diameter is 12 units.

As a result, the equations that depict circles with a centre on the y-axis and a diameter of 12 units are as follows:

(x-0)² + (y-h)² = r², where h is the y-coordinate of the center and r is the radius of the circle.

(x-0)² + (y-k)² = r², where k is the y-coordinate of the center and r is the radius of the circle.

2 = r2, where k is the circle's center's y-coordinate and r is its radius.

We can see from these equations that circles with a diameter of 12 units and a centre on the y-axis are represented by the following equations:

x² + (y-6)² = 36 (center at (0,6))

x² + (y+6)² = 36 (center at (0,-6))

As a result, the following choices depict circles that satisfy these requirements:

x² + (y-6)² = 36

The approximate zero of P(x) is 1.87, and the polynomial is P(x) = x5 − 2x2 − 12.

When finding the real zero in the interval [1,2] using the Intermediate Value Theorem and polynomial P(x) = x5 − 2x2 − 12, there are several steps to follow. We will outline them below. Step 1: State the Intermediate Value Theorem (IVT)The Intermediate Value Theorem (IVT) states that if a function is continuous on an interval [a,b], then it takes on every value between f(a) and f(b) at least once. This means that if f(a) and f(b) have opposite signs, the function has at least one real zero between them. This is useful when the function cannot be solved explicitly. Step 2: Determine the values of f(1) and f(2)Plugging in 1 and 2 to the polynomial P(x) = x5 − 2x2 − 12, we get: f(1) = (1)5 − 2(1)2 − 12 = −13f(2) = (2)5 − 2(2)2 − 12 = 8Hence, f(1) and f(2) have opposite signs, so by the Intermediate Value Theorem, the polynomial P(x) = x5 − 2x2 − 12 has at least one real zero in the interval [1,2]. Step 3: Approximate the real zero to two decimal placesTo approximate the real zero of P(x), we can use a graphing calculator or an iterative method such as Newton's method. Using a graphing calculator, we find that the real zero of P(x) in the interval [1,2] is approximately 1.87 (rounded to two decimal places).Therefore, the approximate zero of P(x) is 1.87, and the polynomial is P(x) = x5 − 2x2 − 12.
