The values of x in f(x)=2x g(x)=2^x is x=2 and x=0.77.
What is the solution for an equation?
The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
We are given that;
f(x) 2x and g(x)=2^x
Now,
To graph the functions on the same coordinate plane, we can plot some points and connect them with a line:
f(x) = 2x
(0, 0), (1, 2), (2, 4), (3, 6), ...
g(x) = 2^x
(0, 1), (1, 2), (2, 4), (3, 8), ...
To find the solutions to the equation f(x) = g(x), we need to set the two expressions equal to each other and solve for x:
2x = 2^x
x=2, 0.77
Therefore, the answer of the given equation will be x=2, 0.77

The fact that both rays are equal in the case at hand is not given, hence the incorrect statement will be (A) AB = AC.
What are rays?By selecting a curve that is perpendicular to the wavefronts of the actual light and points in the direction of energy flow, one can create an idealized geometrical model of light or other electromagnetic radiation known as a ray in the field of optics.
By segmenting the actual light field into discrete rays that can be computationally propagated across the system using ray tracing techniques, rays are used to mimic the propagation of light through an optical system.
As a result, even extremely complicated optical systems can be mathematically or computationally investigated.
For as long as light waves travel through and around objects whose dimensions are significantly larger than the light's wavelength, approximate solutions to Maxwell's equations are appropriate for use in ray tracing.
So, in the given situation it is nowhere given that both rays are equal, and hence the wrong statement will be AB = AC.
Therefore, the fact that both rays are equal in the case at hand is not given, hence the incorrect statement will be (A) AB = AC.

What is the percent yield formula?
Answers
Answer:
Step-by-step explanation:
The percent yield formula is used to calculate the efficiency of a chemical reaction in producing a desired product. It is defined as the ratio of the actual yield of a product to its theoretical yield, expressed as a percentage.
The formula for percent yield is:
Percent Yield = (Actual Yield / Theoretical Yield) * 100%
where:
Actual Yield is the amount of product actually produced in the reaction.
Theoretical Yield is the maximum amount of product that could be produced in a reaction under ideal conditions, calculated from the stoichiometry of the reaction.
By using this formula, you can determine how well a reaction is performing and identify areas for improvement to increase the yield of the desired product.
A student needs at least three notebooks and three pencils. Notebooks cost #60 and pencils #36 and the student has #360 to spend. The student decides to spend as much as possible of his #360. a How many ways can he spend his money? b Does any of the ways give him change? If so, how much?
Answers
Answer:
Two ways.
(1) 4 notebooks,3 pencils, have change $12;
(2)3 notebooks, 5 pencils, have no change.
Step-by-step explanation:
set student buy x notebooks and y pencils,
x≥3,y≥3,
60x+36y≤360
if x=3, 180+36y≤360
36y≤180
y≤5
and y≥3, so y={3,4,5}
(1)when y=3, 60x≤360-36x3=252, x≤4.2,so x=4,
and change=360-36x3-60x4=12
(2)when y=4, 60x≤360-36x4=216, x≤3.6,so x=3,
and change=360-36x4-60x3=36, since student have to spend as much as possible of his money, $36 can buy a pencil, so this is not accepted.
(3)when y=5, 60x≤360-36x5=180, x≤3, so x=3,
and change =360-36x5-60x3=0
The student has two ways to spend his money on notebooks and pens. In one option, she can buy 4 notebooks and 3 pens and in the other option she can buy 3 notebooks and 5 pens.
How to find the possibilities of the student to buy pens and notebooks?To find the student's possibilities to buy pens and notebooks we must take into account his total budget of $360. Additionally, the values of the notebooks and pens that are: $60 and $36 respectively.
We must multiply the value of the notebooks by the number of notebooks that we believe the student can buy, this would be a range between 3 and 4 notebooks. Additionally, once we decide the number of notebooks we can divide the remaining money in the value of the pens to find the number of pens that the student can buy. According to the above:
4 * 60 = 240360 - 240 = 120120 / 36 = 3,33336 * 3 = 108108 - 120 = 123 * 60 = 180360 - 180 = 180180 / 36 = 55*36=180Learn more about notebooks in: https://brainly.com/question/29462625

line y= 2x-1 is there 30,61 on the line?
Answers
No, The point (30, 61) does not lie on the given line y = 2x - 1.
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
Given that,
The line,
y = 2x -1
To check if the point (30, 61) is on the line y = 2x - 1, we need to substitute x = 30 and y = 61 into the equation and see if the equation holds true.
So, we have:
y = 2x - 1
61 = 2(30) - 1
61 = 60 - 1
61 = 59
Since 61 is not equal to 59, the point (30, 61) is not on the line y = 2x - 1.

What is the surface area of the square pyramid net?
Answers
The surface area of a square pyramid net can be found by adding the areas of the base and the four triangular faces.
First, find the area of the base by multiplying the length and width of the square base.
Area of base = length × width
Next, find the area of one of the triangular faces by using the formula:
Area of triangle = 0.5 × base × height
Since there are four triangular faces in a square pyramid, multiply the area of one triangle by four to find the total area of the triangular faces.
Area of triangular faces = 4 × (0.5 × base × height)
Finally, add the area of the base and the area of the triangular faces to find the total surface area of the square pyramid net.
Surface area = Area of base + Area of triangular faces
= (length × width) + (4 × (0.5 × base × height))
= (length × width) + (2 × base × height)
So, the surface area of a square pyramid net is the sum of the area of the base and the area of the four triangular faces.

If f(x) is continuous on a closed interval, then it is enough to look at the points where f'(x) = 0 in order to find its absolute maxima and minima. Be prepared to justify your answer.
Answers
While looking at the critical points of a function f(x) is a useful first step in finding its maxima and minima, it is not enough by itself to determine all of them.
The statement is partially correct. If a function f(x) is continuous on a closed interval, it is possible to find its absolute maxima and minima by looking at the points where f'(x) = 0, but this is not enough to guarantee that you have found all of them.
The reason why this is the case is because the condition f'(x) = 0 only identifies critical points, which are points where the function may have an extremum (either a maximum or a minimum). To determine whether a critical point is indeed a maximum or a minimum, you need to analyze the behavior of the function near the critical point.
One way to do this is by using the second derivative test, which states that if f(x) is twice differentiable and f''(x) > 0 at a critical point x, then f(x) has a local minimum at x. Similarly, if f''(x) < 0 at a critical point x, then f(x) has a local maximum at x.
You also need to use additional tools, such as the second derivative test, to verify whether the critical points are indeed extrema.

What is the known probability when two events will both occur such that the probabilities of the individual events are from its product?
Answers
Answer:
The probability that two independent events will both occur can be calculated by multiplying the probabilities of the individual events. If event A has probability p(A) and event B has probability p(B), then the probability that both events A and B occur is given by:
p(A and B) = p(A) * p(B)
This relationship holds because the occurrence of event A does not affect the occurrence of event B, and vice versa. Hence, the two events are considered to be independent.
For example, if event A has a probability of 0.6 of occurring and event B has a probability of 0.7 of occurring, then the probability that both events will occur is 0.6 * 0.7 = 0.42.
