What percent of the
square is shaded in?
When you type your answer
do not include a % sign.
Answers
Answer:
1 1/3 or just 1/3
Step-by-step explanation:
What percent of the shape is shaded in?
Alright to start, let's look at the shape, it is divided into 4 equal parts, one part is shaded, which gives us 1/4, or 25% or 0.25. Then there's another part, which is half shaded, that'll be half of 1/4 or 25% or 0.25, which is 1/8 or 12.5% or 0.125. Now all you have to do is add them together.
1/4 + 1/8 = 3/8
25% + 12.5% = 37.5%
0.25 + 0.125 = 0.3725
These are your three answers you can choose from, I guess the second one won't work because the problem states not to include a % sign.
Hope this helped!

give an example of a function f(x) for a commonly encountered physical situation where f(x) is discontinuous. you must provide clear definitions for x and f(x) related to your selected physical application and then discuss points where this function is discontinuous.
Answers
An example of a function that represents a commonly encountered physical situation where f(x) is discontinuous is the position-time function for a particle undergoing a sudden change in velocity.
Let's consider a particle moving along a straight line. Before a specific time, let's say t = 0, the particle is moving with a constant velocity v1, and its position is given by f(x) = v1t. At t = 0, there is a sudden change in the particle's velocity, and it starts moving with a different constant velocity v2. In this case, the position-time function can be written as f(x) = v1t for t < 0 and f(x) = v2t for t ≥ 0. Here, x represents the position of the particle, t represents time, and f(x) represents the position of the particle at a given time.
At t = 0, there is a discontinuity in the function because the velocity of the particle abruptly changes from v1 to v2. This results in a sudden jump or break in the position-time function. The function is not continuous at t = 0 since the left and right limits of the function do not match. In physical terms, this situation could represent, for example, a car moving with a constant speed and then suddenly changing its velocity when it encounters a traffic light or when the driver applies the brakes. At the moment of the velocity change, there is a discontinuity in the position-time function, indicating a sudden shift in the car's position.

) suppose that the group of ten students consists of six freshmen and four sophomores. in how many different ways can four equal scholarships be distributed if at least two of the scholarships should be awarded to freshmen?
Answers
There are 90 different ways in which the four scholarships can be distributed such that at least two are awarded to freshman students.
We first need to determine the number of ways in which we can choose two of the six freshman students to receive scholarships. This can be done using the binomial coefficient formula: \(${6 \choose 2} = 15$\).
Next, we need to determine the number of ways in which we can choose two of the four sophomore students to receive scholarships. This can also be done using the binomial coefficient formula: \(${4 \choose 2} = 6$\)
Finally, we need to multiply these two values together to get the total number of ways in which the scholarships can be distributed: 15 * 6 = 90. Therefore, there are 90 different ways in which the four scholarships can be distributed such that at least two are awarded to freshman students.

The expression 19(\(\sqrt[5]{8}\))^4 in rational exponent form is (152)^(4/5) and the expression (-4)^(2/7) in radical form is \(\sqrt[7]{(-4)^{2} }\).
What is rational exponent form?
In the formula a^(p/q), where a is the base and p/q is the rational exponent and q≠0, rational exponents are exponents of numbers that are expressed as rational numbers.
The first expression is -
19(\(\sqrt[5]{8}\))^4
Solve it to get rational exponent form -
Apply the rule n√x^m=x^(m/n) to rewrite the expression as a rational exponent.
= 19(\(\sqrt[5]{8}\))^4
= 19 × (\(\sqrt[5]{8}\))^4
= 19 × (8)^(4/5)
= (152)^(4/5)
The second expression is -
(-4)^(2/7)
Solve it to get the radical form -
Apply the rule x^(m/n)=n√x^m to rewrite the expression as a radical.
= (-4)^(2/7)
= \(\sqrt[7]{(-4)^{2} }\)
Therefore, the values are obtained as (152)^(4/5) and \(\sqrt[7]{(-4)^{2} }\).

C) representar graficamente la situacion planteada D) ¿que representa en este caso la ordenada al origen? Si alguien me ayuda, de verdad se lo agradezco
Answers
Answer:
El costo es:
Primero tenemos un cargo fijo de $140.
Luego tenemos un $25 por cada m^3 consumido.
Entonces, si tenemos x m^3 consumidos en un mes, el cargo de ese mes va a ser:
C(x) = $140 + $25*x.
Esto es una relación linear.
A) En este caso tendríamos x = 140
C(140) = $140 + $25*140 = $3640
B) La formula es, como ya escribimos arriba, C(x) = $140 + $25*x.
C) El grafico estará al final. En el podemos ver que la linea corta el eje vertical en y = $140, que seria lo minimo que se puede pagar al mes, en el caso de que el consumo sea x = 0.
D) La ordenada al origen es $140, representa el cargo fijo que no depende de la variable x.

Consider the line in the coordinate plane that passes through the point (-7, -3) and the origin. Find the slope of a line perpendicular to the line described.
A) -1/3
B) -3/7
C) -7/3
D) 3/7
Answers
The line passing through (-7, -3) and the origin has a slope of 3/7. A line perpendicular to it has a slope of -7/3.
The line passing through the point (-7, -3) and the origin has slope equal to the ratio of the change in the y-coordinate to the change in the x-coordinate as we move from the origin to the point (-7, -3). This is given by:
slope = (change in y-coordinate) / (change in x-coordinate)
= (-3 - 0) / (-7 - 0)
= 3/7
So the slope of the given line is 3/7.
A line perpendicular to this line will have a slope that is the negative reciprocal of 3/7. That is,
slope of perpendicular line = -1 / (3/7) = -7/3
Therefore, the answer is (C) -7/3.

Find the derivative of the function f by using the rules of differentiation. f(x) = 390 , f'(x) =
Answers
The derivative of the function f(x) = 390 by using the rules of differentiation is f'(x) = 0.
To find the derivative of the function f(x) = 390, we can apply the rules of differentiation.
In this case, the function f(x) = 390 is a constant function, which means it does not depend on the variable x. The derivative of a constant function is always zero.
Therefore, the derivative f'(x) of the function f(x) = 390 is:
f'(x) = 0
The derivative of a constant function is zero because a constant value does not change with respect to the variable x. So regardless of the value of x, the rate of change of the function is always zero.

The mean of the distribution is 15.0 minutes and the standard deviation is 3.5 minutes. What is the probability that a particular listener will tune in:
a. More than 20 minutes? b. For 20 minutes or less
Answer: 0.0764 ; 0.9236
Step-by-step explanation:
Mean (m) = 15 minutes
Standard deviation (sd) = 3.5
Z - score :
Z = (x - m) / sd
A) more than 20 minutes
P(X > 20) ; x = 20
Z > (20 - 15) / 3.5 = 5/3.5 = 1.429
P(z > 1.429) = 0.5 - P(0<z<1.43)
Using the z-table: 1.43 = 0.4236
0.5 - 0.4236 = 0.0764
2) 20 minutes or less :
P(X <= 20) ; x = 20
Z < (20 - 15) / 3.5 = 5/3.5 = 1.429
P(z < 1.429) = 0.5 + P(0<z<1.43)
Using the z-table: 1.43 = 0.4236
0.5 + 0.4236 = 0.9236

2)εR = Rε = R
3)ØR = RØ = R
Answers
Let R be a Regular Expression, ε be the empty string, and Ø be the empty set, then the correct statement isεR = Rε = R.
In particular, we have:
εR = Rε = R
This is since every expression R accepts a string of length 0, which is the empty string ε, and concatenating ε to the end of any string has no impact on its value.
The second statement is incorrect because the empty set Ø contains no string, and thus the expression ØR does not include any strings, while RØ will still result in Ø even if R generates a set of strings.
As a result, the correct statement is option 2) εR = Rε = R.
