Answer:

C. f^-1(x) = 1/5 x

Step-by-step explanation:

f(x) = 5x

y = 5x

x = 5y

y = 1/5 x

Answer: C. f^-1(x) = 1/5 x

Answer:

C,\(\frac{1}{5} x\)

Step-by-step explanation:

This is because anything to the power of a negative, always turns to a fraction because you cannot have a negative fraction. It will turn positive if you put \(\frac{1}{x}\), or that number (x). Since there is a 1 as the negative exponent, you do not need to show it as u do for other ones such as:

\(\frac{1}{x^{2} }\) which is \(x^{-2}\).

The angles that share the same sine value as sin(45°) have terminal sides in second quadrant .

The sine function relates the ratio of the length of the side opposite an acute angle to the length of the hypotenuse of a right triangle. The sine of an angle is always between -1 and 1.

The sine of 45 degrees is √2/2, which is a positive value. Since the sine of an angle is positive in the first and second quadrants, the angles that share the same sine value as sin(45°) must have their terminal sides in the first or second quadrant.

To find the angles that have the same sine value as 45 degrees, we can use the inverse sine function, also known as the arcsine function. The arcsine of √2/2 is 45 degrees or π/4 radians, which is an angle in the first quadrant.

However, since the sine function is periodic, there are infinitely many angles with the same sine value as 45 degrees, and they are all separated by integer multiples of 360 degrees or 2π radians.

Therefore, the angles that share the same sine value as sin(45°) have terminal sides in second quadrant, and can be represented by the formula:

θ = n(360°) ± 45°

or

θ = n(2π) ± π/4

where n is an integer.

If the long-term demand for oranges is the same as the short-term demand, a binding price ceiling will result in a shortage that is larger in long-run demand than the short-run demand. So the answers are shortage and larger.

A shortage occurs when there is a difference between the quantity that is supplied and the quantity that is required of a product, service, or resource. Surplus is a term used to describe situations where there is more supply than demand for a product, service, or resource.

So when the long-run demand is the same as the short-run demand, binding price ceilings typically result in a shortage when there is a lack of supply of products. And, the result will be larger in the case of the long run compared to the short run. Therefore, the first blank can be filled with shortage and the second blank with larger.

The dependent variable, y in this scenario is; height.

It follows from the task content that the two variables which describe the growth model of the plants are; weeks and height.

Since, independent variable as the name implies is one whose values do not arrive from evaluation using other values, the independent variable in this scenario is; weeks.

However, by logic, the height of the plant is determined by the number of weeks and hence is dependent on the variable weeks. Therefore, the dependent variable is; height.

Answer:

\(P(A\ and\ B) = \frac{3}{7}\)

Step-by-step explanation:

Your question is not well presented; (See Attachment for complete details)

Required

Find P(A n B)

where

A = Event that the place is a city

B = Event that the place is in North

The first step is to get the sample space;

Let S represent the sample space;

\(S = \{India,\ Tokyo,\ Houston,\ Peru,\ New York,\ Tijuana,\ Canada \}\)

\(n(S) = 7\)

The next is to list events A and B

A = City

\(A = \{Tokyo,\ Houston,\ New York,\ Tijuana\}\)

B = North America

\(B = \{Houston,\ New York,\ Tijuana,\ Canada\}\)

The next is to list common elements in A and B

\(A\ n\ B = \{Houston,\ New York,\ Tijuana\}\)

\(n(A\ and\ B) = 3\)

The probability of A and B is calculated as follows;

\(P(A\ and\ B) = \frac{n(A\ and\ B)}{n(S)}\)

Substitute \(n(A\ and\ B) = 3\) and \(n(S) = 7\) in the expression above

\(P(A\ and\ B) = \frac{3}{7}\)

Answer:

f(50) = 31928.24 thousands

Therefore, it means that the US population in year 1850 is 31928.24 thousands

Step-by-step explanation:

Given the function;

f(x)=165.6x^1.345

Where;

f(x) is in thousand and

x is the number of year after 1800

To determine f(50), we will substitute x = 50 into the function of f(x);

f(50)=165.6(50)^1.345

f(50) = 31928.24 thousands

Since f(50) is the US population in year 1800+50 = 1850

Therefore, the US population in year 1850 is 31928.24 thousands

the control group in an experiment refers to the group of individuals who do not receive the treatment under investigation. They serve as a reference point for evaluating the effects of the treatment and help researchers draw conclusions about the association between the treatment variable and the outcome variable.

In experimental research, the control group serves as a comparison or reference point for evaluating the effects of a specific treatment. The control group consists of individuals who are selected from the same population as the treatment group but do not receive the treatment being investigated.

By having a control group, researchers can assess the impact of the treatment by comparing the outcomes between the treatment group and the control group. This comparison helps determine whether any observed changes or effects are due to the treatment itself or other factors.

The control group is essential for establishing a baseline against which the treatment group's results are measured. It allows researchers to assess the causal relationship between the treatment variable and the outcome variable by isolating the effects of the treatment from confounding variables.

sin(x) is a mathematical function that calculates the sine of angle x, where x is in radians.

In mathematics, angles are measured in radians or degrees. The symbol π represents the mathematical constant pi, which is approximately equal to 3.14159.

When we say π/2, it means half of the circumference of a circle, which corresponds to 90 degrees.

The inequality "π/2 < 0" suggests that π/2 is less than zero, implying that the angle of 90 degrees is negative. However, this is incorrect.

In the standard coordinate system, angles are measured counterclockwise from the positive x-axis.

Thus, π/2 or 90 degrees lies in the positive direction. The correct relationship should be "π/2 > 0" to indicate that the angle is greater than zero.

Answer:

A. plug in 2 to x in the given equation: 10 - 2(2)

multiply first: 10 - 4

solve: 6

B. plug in 1/2 to the given equation: 10 - 2(1/2)

C. plug in -2 to the given equation: 10 - 2(-2)

multiply first (remember a - times a - is a +): 10 + 4

solve: 14

The equation of the line in function notation is  

\(y = mx - 3m - 2\)  

Step 1: y - (-2)

To write the equation of the line in function notation, we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is a point on the line. In this case, the slope is given as "m," and the point (x1, y1) is (3, -2).

Substituting these values into the equation, we get:

y - (-2) = m(x - 3)

Simplifying the expression in the left-hand side, we get:

y + 2 = m(x - 3)

This is the equation of the line in point-slope form. To write it in function notation, we can solve for y:

y = mx - 3m - 2

This is the equation of the line in function notation. We can use this equation to find the y-value of the line for any given x-value. For example, if we want to find the y-value of the line when x = 5, we can substitute x = 5 into the equation and solve for y:

y = m(5) - 3m - 2 = 2m - 2

So when x = 5, the y-value of the line is 2m - 2.

\(Pr = 0.67\)

Step-by-step explanation:

Given

\(Start = 8:10:00\)

\(End = 8:21:59\)

\(You = 8:18:00\)

Required

Chances that you missed the appointment

First, calculate the number of minutes of the radio station

\(n = End - Start\)

\(n = 8:21:59 - 8:10:00\)

\(n = 11\ min\ 59\ secs\)

Convert to seconds

\(n = 719\)

Since you turn on at 8:18:00, then you've missed the broadcast from the start till 8:18:00

So, we have:

\(Missed = 8:17:59 - 8:10:00\)

\(Missed = 7\ mins\ 59\ secs\)

Convert to seconds

\(Missed = 479\)

The probability that you missed is:

\(Pr = \frac{Missed}{n}\)

\(Pr = \frac{479}{719}\)

\(Pr = 0.67\)
