then for the last part
4^-4 is the same as [tex]1/4^{4}[/tex] or 1/256

The fraction of pizza that each of them gets out of the whole pizza is 1/9.
What is meant by a fraction?
The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line. A piece or sector of any quantity is another name for the fraction. Some of the different types of fractions are:
proper fractions, improper fractions, mixed fractions and so on.
Given 1/3rd portion of the pizza is shared by Nicole, James and Jenny.
Let us are assuming they shared the 1/3rd portion equally among themselves.
Then,
1/3 pizza = 3 people
1 person = 1/(3*3) = 1/9
Therefore the fraction of pizza that each person gets out of the whole pizza is 1/9.

Emma was ranked 54th in his graduating class of 296 students. At what percentile is Emma’s ranking?

Answer: 54 is 18.24% of 296
Step-by-step explanation:
54:296*100 =
(54*100):296 =
5400:296 = 18.24
Now we have: 54 is what percent of 296 = 18.24
Question: 54 is what percent of 296?
Percentage solution with steps:
Step 1: We make the assumption that 296 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100% = 296
Step 4: In the same vein, x% = 54
Step 5: This gives us a pair of simple equations:
100% = 296 (1)
x% = 54 (2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left-hand side) of both equations have the same unit (%); we have
100% over x% = 296 over 54
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% over 100% = 54 over 196
x=18.54

Only one decimal place in the product of 8x0. 5 because the final zeros in the product do not change the value of the number.
One decimal place to the left of the decimal point is the ones place. One decimal place to the right of the decimal place is the tenths place.
This is a result of the rules of significant figures. These are the digits of the numbers that matter. For operations involving multiplication, the product should have the same significant numbers with the least significant numbers of the given data. In this case, that would be 0.5.

find the volume of the cylinder 9in and 5in
Answers
706.5 in³
Step-by-step explanation:The volume of a shape describes the amount of space a shape takes up.
Volume Formula
For a cylinder, the volume formula is V = πr²h. In this formula, V represents the total volume. Additionally, π represents the constant pi, which is approximately 3.14. The variable r represents the radius. Remember that radius is the distance from the center of the circle to the edge. Finally, h is the height of the cylinder.
Solving for Volume
The diagram shows that the radius is 5in. We know this because the distance from the center to the edge of the circle is 5in. Additionally, the height is 9in. Now, we can plug these values into the formula.
V = π(5)² * 9V = 225πV ≈ 706.5For this calculation, I used 3.14 for π. The unrounded volume in terms of pi is 225π.
The volume of the cylinder is 706.5 in³.

For g(x), we have:
g(x) = 4^bx = (2^2)^bx = 2^(2bx)
Since 2^x = f(x), we can set 2bx = x to find b. Solving for b, we get:
b = 1/2
For h(x), we have:
h(x) = 8^bx = (2^3)^bx = 2^(3bx)
Since 2^x = f(x), we can set 3bx = x to find b. Solving for b, we get:
b = 1/3
For j(x), we have:
j(x) = (1/2)^bx = 2^(-bx)
Since 2^x = f(x), we can set -bx = x to find b. Solving for b, we get:
b = -1
So, for g(x) = 4^bx, b = 1/2; for h(x) = 8^bx, b = 1/3; and for j(x) = (1/2)^bx, b = -1.
An equilateral triangle is similar to a scalene triangle.1) Always2) never3) sometimes
Answers
Option 3) Sometimes is the correct answer, Sometimes an equilateral triangle is similar to a scalene triangle.
If the respective sides are proportional and the corresponding angles are congruent, two triangles are comparable. An equilateral triangle has three congruent sides and three congruent angles, so any triangle that is similar to an equilateral triangle must also have three congruent angles. However, a scalene triangle has no congruent sides and no congruent angles, so it is possible for a scalene triangle to be similar to an equilateral triangle only if it has the same angle measurements as an equilateral triangle, but with different side lengths. Therefore, a scalene triangle can be similar to an equilateral triangle, but it is not always the case.
In general, if two triangles are similar, it means that they have the same shape but possibly different sizes. In the case of an equilateral triangle and a scalene triangle, if they are similar, then it means that the scalene triangle has the same angles as the equilateral triangle, but its sides are of different lengths. So it is possible for a scalene triangle to be similar to an equilateral triangle, but not in all cases.

show that the wave function y=e^(b(x-vt)) is a solution of the linear wave equation (eq. 16.27), where b is a constant
Answers
To show that the wave function y=e^(b(x-vt)) is a solution of the linear wave equation (eq. 16.27), we need to plug the wave function into the equation and see if it satisfies the equation.
The linear wave equation (eq. 16.27) is given by:
∂^2y/∂x^2 = (1/v^2) ∂^2y/∂t^2
Plugging in the wave function y=e^(b(x-vt)) into the equation, we get:
∂^2(e^(b(x-vt)))/∂x^2 = (1/v^2) ∂^2(e^(b(x-vt)))/∂t^2
Taking the second derivative with respect to x, we get:
b^2 e^(b(x-vt)) = (1/v^2) ∂^2(e^(b(x-vt)))/∂t^2
Taking the second derivative with respect to t, we get:
b^2 e^(b(x-vt)) = (1/v^2) b^2 v^2 e^(b(x-vt))
Simplifying, we get:
b^2 e^(b(x-vt)) = b^2 e^(b(x-vt))
This shows that the wave function y=e^(b(x-vt)) satisfies the linear wave equation (eq. 16.27) and is therefore a solution of the equation.
