Michio's answer not correct. He made a mistake when he was trying to convert the equation to logarithmic form. The right answer is  2.57

Looking at the equation 2(3)ˣ = 34, the best way to convert to logarithm is by isolating x.

we divide  2(3)ˣ = 34 by 2 on both side.

= (3)ˣ = 17

In logarithm form 3 becomes the base of the log

x = log₃(17)

x= 2.578

The answer above is based on the information seen in the picture.

Michio wanted to find the value of x in the equation 2(3)ˣ = 34. He first converted the equation to log₃2x = 17. Next, he wrote 2x = 3¹⁷ and used a calculator to find x = 64,570,081.5. Was his answer correct? If not, what was his mistake and what is the right answer? Justify your answer.

The standard form of the equation for the circle is (x - 3)² + (y - 2)² = 8.

In Mathematics and Geometry, the standard form of the equation of a circle is represented by the following mathematical equation;

(x - h)² + (y - k)² = r²

Where:

Note: A center that lies on the y-axis simply means the value of h on the x-axis is equal to 0.

Based on the information provided above, we have the following parameters:

Radius, r = √[(3 - 5)² + (2 - 4)²] = √8

Center, (h, k) = (3, 2).

By substituting the given parameters into the equation of a circle formula, we have the following;

(x - h)² + (y - k)² = r²

(x - 3)² + (y - 2)² = (√8)²

(x - 3)² + (y - 2)² = 8.

In a function expressing altitute (h) in terms of time (t), finding the vertex will provide the time and altitute when the object reaches the maximum height. Therefore, let's use the vertex formula to see exactly when this happens:

"x" vertex value: [tex]-\dfrac{-b}{2a}[/tex]

a) For using that equation, first write the given equation on its standard form.

Standard form of quadratic equations: [tex]ax^{2} +bx+c=0[/tex]

b) You can substitute h(t) by 0 on the origina equation:

[tex]-0.2t^{2} +2t=0[/tex]

c) Idenfity the coefficients.

a= -0.2, beacuse "t²" is being multiplied by -0.2.

b= 2, beacuse "t" is being multiplied by 2.

d) Substitute in the formula and calculate.

[tex]\sf X\,value_{Vertex} =-\dfrac{-b}{2a}=-\dfrac{-(2)}{2(-0.2)}=-\dfrac{-(2)}{-0.4}=5[/tex]

So the "x" value of this h(t) equation is located on x= 5, therefore, the maximum point happens at x= 5. Since this is an equation that expresses altitute in terms of time, this means that 5 seconds after the object starts its movement it reaches its maximum altitute.

The probability that the team wins the debate is 0.6475

P(win) = P(win | S)P(S) + P(win | J)P(J) + P(win | R)P(R)

= (0.25)(0.2) + (0.6)(0.35) + (0.85)(0.45)

= 0.6475

Therefore, the probability that the team wins the debate is 0.6475.

In order to simulate the probability that a Sophomore is never selected to give the closing argument in the next 5 debates, we can use the following steps:

Create a table of random digits with enough rows and columns to simulate the 5 debates. Each row represents a debate and each column represents a team member.

Assign the digits 0, 1, and 2 to represent the events that a sophomore, junior, and senior gives the closing argument, respectively.

Starting from the first row and first column, read the digits from the table and determine which team member gives the closing argument for the first debate.

If a sophomore is selected, record a 0 for that debate. Otherwise, record a 1.

Repeat steps 3 and 4 for the remaining debates, filling in the table as you go.

Calculate the proportion of simulations where a Sophomore is never selected to give the closing argument in the next 5 debates.

If function "h" is one-to-one function which is having values h(-9) = 5, and h(3) = -4, then the inverse statement is (d) h⁻¹(-4) = 3.

We know that the function "h" is a one-to-one function, so, it has an inverse function (h⁻¹). To find the inverse function, we need to exchange  roles of "x" and "y" and solve for y. This gives:

x = h(y)

y = h⁻¹(x)

The given values of function "h" are h(-9) = 5 and h(3) = -4, we find the values of h⁻¹(5) and h⁻¹(-4):

h(-9) = 5

So, h⁻¹(5) = -9 (by exchanging roles of x and y)

and h(3) = -4

So, h⁻¹(-4) = 3 (exchanging the roles of x and y)

The function "h⁻¹(-4) = 3" is represented in option (d).

Piston movement compresses air in Small compressors type of air compressor

Piston movement compresses air in small compressors. Small compressors, also known as portable compressors, are commonly used for home improvement projects, powering tools, and inflating tires or other objects. The piston moves back and forth inside a cylinder, compressing air and increasing its pressure. The compressed air is then stored in a tank until it is needed to power a tool or inflate an object.

Small compressors are generally less powerful than medium or industrial compressors, but they are more affordable, portable, and easier to use for smaller tasks. They can be powered by electricity or gasoline, and they come in a range of sizes and capacities to meet different needs. Overall, piston-driven small compressors are an efficient and cost-effective way to compress air for various applications.

The surface area of the pyramid is approximately 74.24 square inches.

What is a pyramid?

A pyramid is a three-dimensional geometric shape that has a polygonal base and triangular faces that meet at a single point called the apex. The most common type of pyramid is a square pyramid, which has a square base and four triangular faces.

To find the surface area of the pyramid, we need to find the area of each of the four triangular faces and the area of the square base, and then add them up.

The area of each triangular face can be found using the formula:

Area = (1/2) * base * height

where the base is one of the sides of the square base and the height is the slant height of the pyramid.

The slant height of the pyramid can be found using the Pythagorean theorem:

slant height² = height² + (1/2 * base)²

where the height is the height of the pyramid, which is given as 7 inches, and the base is 4 inches.

height = 7 in.

base = 4 in.

slant height² = 7² + (1/2 * 4)² = 49 + 4 = 53

slant height = √53 ≈ 7.28 in.

Now we can find the area of each triangular face:

Area = (1/2) * base * height = (1/2) * 4 * 7.28 ≈ 14.56 in^2

There are four triangular faces, so the total area of the triangular faces is:

4 * 14.56 = 58.24 in²

The area of the square base is:

Area = side² = 4² = 16 in²

Finally, we can find the surface area of the pyramid by adding up the area of the triangular faces and the area of the square base:

Surface Area = 58.24 + 16 = 74.24 in²

Therefore, the surface area of the pyramid is approximately 74.24 square inches.

Experimental probability and theoretical probability are two different ways to determine the likelihood of an event occurring.

Experimental probability is determined by performing an experiment or conducting observations and collecting data to see how often an event occurs. This method involves counting the number of times an event occurs and dividing that number by the total number of trials or observations.

Theoretical probability, on the other hand, is determined by using mathematical principles and calculations to determine the likelihood of an event occurring. It is based on the assumption that all outcomes are equally likely.
