The number of horizontal asymptotes that graph of y = f(x) can have is (c) 2.
As x approaches negative infinity, the function f(x) approaches the horizontal-asymptote y = 0 because the term 1/x becomes negligible compared to other terms. This occurs in the portion of the function defined as 1/x when x < 0.
As x approaches positive infinity, the function f(x) approaches the horizontal-asymptote y = 2 because the term 2x becomes dominant compared to other terms. This occurs in the portion of the function defined as 2x - 1 when x ≥ 0.
Therefore, the graph of y = f(x) has two horizontal asymptotes: y = 0 as x approaches negative infinity and y = 2 as x approaches positive infinity. The correct answer is (c) 2.

There is at least one boy in my dance class, but more than 94% of the total number of
students are girls. What is the least number of students that could be in my class?
Step-by-step explanation:
.94x = x-1
.06x = 1
x = 16 2/3 which is not a whole number so there must be at LEAST 17 people in class
then if one is a boy there are 16 girls 16/17 = 94.11 % girls with one boy
a two-tailed hypothesis test for a population mean is to be performed at the 1% level of significance. the population standard deviation is known. true or false: the critical values are the two which divide the area under the standard normal curve into a middle 0.98 area and two outside areas of 0.01.
The given statement is false.
In a two-tailed hypothesis test for a population mean, where the population standard deviation is known, the critical values are the values that divide the alpha (significance level) into two equal-tailed regions.
For a 1% level of significance (alpha = 0.01), a two-tailed test allocates half of the alpha to each tail of the distribution. In this case, each tail will have an area of 0.01/2 = 0.005.
The critical values are determined by the standard normal distribution (z-distribution) or by the t-distribution (if the sample size is small and the population standard deviation is unknown). These critical values represent the number of standard deviations away from the mean that correspond to the desired level of significance.
The specific critical values will depend on the sample size, distribution type (z or t), and the desired level of significance. To obtain the critical values, one would consult a standard normal distribution table or a t-distribution table, depending on the case.
In summary, the critical values in a two-tailed hypothesis test do not necessarily divide the area under the standard normal curve into a middle 0.98 area and two outside areas of 0.01. The allocation of the alpha (significance level) is determined based on the desired level of significance, and the critical values are obtained from the appropriate distribution table.

a) the distance in picometers is 135 pm. b) the distance in picometers is 135 pm. c) The answer is 7.0 × 10^4 atoms. d) The volume of a single gold atom is 9.15 × 10^(-24) cm^3.
Part A:
1.35 Å = 0.135 nm (since 1 Å = 0.1 nm)
Therefore, the distance in nanometers is 0.135 nm.
Part B:
1.35 Å = 135 pm (since 1 Å = 100 pm)
Therefore, the distance in picometers is 135 pm.
Part C:
The length of one gold atom is 1.35 Å = 1.35 × 10^(-10) m.
The number of atoms required to span a distance of 9.5 mm = (9.5 × 10^(-3) m) / (1.35 × 10^(-10) m) = 70,370 atoms.
Rounding to two significant figures, the answer is 7.0 × 10^4 atoms.
Part D:
Assuming the gold atom is a sphere, its volume can be calculated as:
V = (4/3)πr^3, where r is the radius of the atom.
Substituting the value of the radius (1.35 Å = 1.35 × 10^(-10) m) gives:
V = (4/3)π(1.35 × 10^(-10))^3 = 9.15 × 10^(-30) m^3.
Expressing this in cubic centimeters gives:
V = 9.15 × 10^(-30) × 10^6 = 9.15 × 10^(-24) cm^3.
Therefore, the volume of a single gold atom is 9.15 × 10^(-24) cm^3.

(a) Estimate the value of the limit lim (1 + x)^1/x to five decimal places.
x?0
We can use the fact that as x gets closer and closer to 0, the expression (1 + x)^1/x gets closer and closer to a certain value. The value of the limit to five decimal places is: 2.71828
One way to estimate this value is to use a calculator or computer program to evaluate the expression for smaller and smaller values of x, until we get a sense of what the limit might be. For example, we can plug in x = 0.001, 0.0001, 0.00001, etc., and see that the expression appears to be approaching a value of approximately 2.71828.
This value is actually a well-known mathematical constant called "e", which is approximately equal to 2.71828. Therefore, we can estimate the value of the limit lim (1 + x)^1/x to five decimal places as e, or approximately 2.71828.
To estimate the value of the limit lim (1 + x)^(1/x) as x approaches 0, we can use the fact that this limit is equal to the mathematical constant e.

A survey was given to a random sample of 85 voters in the United States to ask about
their preference for a presidential candidate. Of those surveyed, 68 respondents said
that they preferred Candidate A. Determine a 95% confidence interval for the
proportion of people who prefer Candidate A, rounding values to the nearest
thousandth.
The 95% confidence interval for the proportion of people who prefer Candidate A is 0.8 ± 0.080.
How do we calculate?Confidence Interval = Sample Proportion ± Margin of Error
We first determine the values for each term:
Sample Proportion = Number / Total sample size
Sample Proportion = 68/85
Sample Proportion = 0.8
Standard Error = √((Sample Proportion * (1 -Sample Proportion )) / n)
n = sample size
Standard Error = √((0.8 * (1 - 0.8)) / 85)
Standard Error = 0.041
We then calculate the Margin of Error = Critical Value * Standard Error Margin of Error = 1.96 * 0.041
Margin of Error = 0.080
We substitute all these values and calculate for :

There are 1234 t shirts that need to be shipped. Each box can fit 32 t shirts. How many boxes are needed to ship all of the t shirts
There are 1234 t shirts that need to be shipped. To ship 1234 t-shirts, a total of 39 boxes are required, as each box can hold 32 t-shirts.
To calculate the number of boxes required to ship 1234 t-shirts, we need to divide the total number of t-shirts by the number of t-shirts that can fit in one box. In this case, as each box can fit 32 t-shirts, we need to divide 1234 by 32.
Using long division, we can find that 32 goes into 1234, 38 times with a remainder of 10. However, we still have 10 t-shirts that need to be shipped, which means we need an additional box to fit them. Therefore, the total number of boxes needed to ship 1234 t-shirts is 39 (38 boxes to fit 1216 t-shirts and 1 additional box to fit the remaining 10 t-shirts).
It's always important to ensure that all the items fit comfortably in the boxes without any damage or risk of items falling out. In this case, we can also use this information to plan and optimize the shipping process by arranging the boxes according to the available storage and transportation capacity.

The following formula is for the area, A ,of the curved surface area of a cone. A=pierl where r is the radius and i
The formula A = πrl represents the curved surface area of a cone, where r is the radius of the base of the cone and l is the slant height.
The curved surface area of a cone is the area of the lateral or side surface of the cone. It is called curved because the surface of the cone is not flat but rather curved, like the surface of a curved cylinder. To derive this formula, we can first imagine a cone with a base that has a circumference of 2πr, where r is the radius of the base. If we cut along a generator line of the cone, we can then unroll the curved surface of the cone to form a sector of a circle with radius l and central angle 2π. The area of this sector is πl^2, which represents the total area of the curved surface of the cone. We can simplify this formula to A = πrl by substituting the value of l with the Pythagorean theorem, l^2 = r^2 + h^2, where h is the height of the cone.

thanks in advance
well, you can look at it this way, if you bend down and put your eye on the angle, the side that you will see across the triangle is going to be the opposite side, so the opposite side is always the side facing off the angle. The adjacent side, is the "adjacent" or "next to" the angle, well, the opposite is across the expanse so is not touching the angle, so the other side that's not slanted is the adjacent or next to the angle.
In this case if we put our eye on the vertex A, what's across the expanse is BC, so the adjacent must be AB.

suppose the largest possible cutout length is 3.5 inches. over what interval of x does the volume of the box decrease as the cutout length gets larger?
The volume of the box decreases as the cutout length increases over the interval (0, 3.5/2) and increases over the interval (3.5/2, infinity).
Let the dimensions of the rectangular box be x, y, and z. The volume of the box is given by V = xyz. Suppose that the cutout length is along the x-axis, and let it be denoted by w. Then, we have:
V = (x - w)yz
Taking the derivative of V with respect to w, we get:
dV/dw = -yz
The volume of the box will decrease as the cutout length increases if dV/dw < 0, and it will increase if dV/dw > 0. Since y and z are positive, dV/dw will be negative if w is less than x/2 and positive if w is greater than x/2. Therefore, the volume of the box decreases as the cutout length increases over the interval (0, x/2) and increases over the interval (x/2, infinity).
In our case, the largest possible cutout length is 3.5 inches, so the interval over which the volume of the box decreases as the cutout length gets larger is (0, 3.5/2), which is (0, 1.75). The interval over which the volume of the box increases is (3.5/2, infinity), which is (1.75, infinity).

The required equation of the circle is (x - 2)² + (y + 3)² = 10².
The standard form of the equation of a circle with center (h, k) and radius r is:
(x - h)² + (y - k)² = r²
Given that the center of the circle is (2, -3), so h = 2 and k = -3.
To find the radius r, we can use the distance formula between the center and the point on the circle:
r = sqrt((x - h)² + (y - k)²)
We are also given that point (8, 5) is on the circle.
Substituting the values of h, k, x, and y into the distance formula, we have:
r = √((8 - 2)² + (5 - (-3))²)
r = √(6² + 8²)
r = 10

25 points!!!what is the quotent? a-3/7 divided by 3-a/21
To divide (a-3/7) by (3-a/21), we need to multiply the numerator by the reciprocal of the denominator.
Reciprocal of (3-a/21) is (21/(3-a))
So,
(a-3/7) / (3-a/21) = (a-3/7) * (21/(3-a))
Now, we can simplify by canceling out common factors between the numerator and denominator.
(a-3/7) * (21/(3-a)) = (3-a)(a-3)/(7*21)
= -(a^2 - 6a + 9)/147
= -(a-3)^2/147
Therefore, the quotient is -(a-3)^2/147.
A right triangle is shown below.

Find the lengths of the missing sides
vertical leg
m
horizontal leg
45°
m
Answer:
Dang, too difficult. Anyways,
In a right triangle, if one angle is 45 degrees, it means that the other two angles must be 45 degrees as well, making it an isosceles right triangle. Given that the length of one leg is 4√2 m, we can determine the lengths of the missing sides using the properties of an isosceles right triangle.
Since an isosceles right triangle has two equal legs, the lengths of the vertical leg and horizontal leg will be the same. Let's denote the length of each leg as "m."
Using the Pythagorean theorem, we can find the length of the hypotenuse (the side opposite the right angle) in terms of "m":
hypotenuse^2 = leg^2 + leg^2
hypotenuse^2 = m^2 + m^2
hypotenuse^2 = 2m^2
To find the length of the hypotenuse, we take the square root of both sides:
hypotenuse = √(2m^2) = √2 * m
Therefore, the length of the hypotenuse is √2 * m.In summary, for the given isosceles right triangle with one leg measuring 4√2 m, both the vertical leg and horizontal leg will have a length of "m," while the length of the hypotenuse will be √2 * m.

Fabian has some dimes and some quarters. He has no more than 28 coins worth a minimum of $4.75 combined. If Fabian has 12 dimes, determine the minimum number of quarters that he could have.
If there are no possible solutions, submit an empty answer.
Answer:
Step-by-step explanation:
The total value of his quarters is Q x $0.25. Therefore, the combined value of his coins is:
$1.20 + Q x $0.25 = $4.75 - $3.55
Simplifying the equation, we get:
Q x $0.25 = $1.20 + $1.20
Q x $0.25 = $2.40
Q = $2.40 / $0.25
Q = 9.6
Since Q must be a whole number, the minimum number of quarters that Fabian could have is 10. (If he had only 9 quarters, the combined value of his coins would be $1.20 + $2.25 = $3.45, which is less than the required minimum of $4.75.)

P(greater than 1): Likely. There are five faces that have a number greater than 1 (2, 3, 4, 5, and 6) and only one face that has a 1.
Therefore, the probability of rolling a number greater than 1 is much higher than the probability of rolling a 1, making it a likely outcome.
P(even): Equally likely. There are three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5) on the cube, so the probability of rolling an even number is the same as the probability of rolling an odd number.
Therefore, P(even) is equally likely.

Levi placed 10 weights on a scale during science class. If each weight weighed 0. 7 grams, what did the scale read?
Levi placed 10 weights on the scale, each weighing 0.7 grams. The total weight of the weights is 7 grams. Therefore, the scale will read 7 grams.
Levi placed 10 weights on the scale, and each weight weighed 0.7 grams. To find the total weight, we need to multiply the weight of one weight by the number of weights. Therefore, the total weight of the weights is 0.7 x 10 = 7 grams. This means that the scale will read 7 grams.
The principle behind this calculation is the law of conservation of mass. This law states that the total mass of a closed system remains constant, regardless of any changes that take place within the system. In this case, the system is the scale and the weights. Since the scale is a closed system, the total mass of the weights placed on it must be equal to the reading on the scale.
Therefore, when Levi placed 10 weights on the scale, the total weight of the weights is 7 grams, and the scale will read 7 grams. This calculation can be used to determine the weight of any number of objects placed on a scale, as long as the weight of one object and the number of objects are known.

The correct statement about step 3 include the following: C. When the equation -3x − 5y = -5 is subtracted from -10x + 5y = -60, a third linear equation, -13x = -65, is formed, and it has a different solution from the original equations.
How to solve these system of linear equations?In order to determine the solution to a system of two linear equations, we would have to evaluate and eliminate each of the variables one after the other, especially by selecting a pair of linear equations at each step and then applying the elimination method.
Given the following system of linear equations:
2x - y = 12 .........equation 1.
-3x - 5y = -5 .........equation 2.
By multiplying the equation 1 by -5, we have:
-5(2x - y = 12) = -10x + 5y = -60
By adding the two equations together, we have:
-3x - 5y = -5
-10x + 5y = -60
-------------------------
-13x = -65
