The answer is:

minimum value = √121/11 = 2/11

maximum value = √17/11

Here's how to solve it:

The given function is c(z) = √z, and the domain interval is 121 ≤ z ≤ 17.

The minimum value of the function occurs at the endpoint of the domain interval where the function takes the smallest value. In this case, the smallest value of the function occurs at z = 17, so the minimum value of the function is:

c(17) = √17

The maximum value of the function occurs at the endpoint of the domain interval where the function takes the largest value. In this case, the largest value of the function occurs at z = 121, so the maximum value of the function is:

c(121) = √121 = 11

Therefore, the minimum value of the function is √17 and the maximum value of the function is 11/√121, which simplifies to 1/11.

Answer:

Bathtub currently has 45 gallons of water.

It drains 7 gallons every three minutes.

How much gallons will it have after 5 minutes.

First, find how much it drains in one minute and multiply it by 5.

7 gallons per 3 minutes.

So 7/3 = 2.3333 or roughly 2 gallons per minute.

How many gallons will it have after 5 minutes of draining.

2*5 = 10 litres will have been drained.

So, 45 - 10 = 35 gallons of water would remain after 5 minutes of draining.

Answer:

approximately 3.84 degrees.

Step-by-step explanation:

The angle of depression is the angle between a horizontal line and the line of sight when looking downwards. We can use trigonometry to calculate this angle.

Let's draw a diagram to represent the situation:

A

/|

/ |

18.5/ | 280

/ |

/θ |

/_____|

B

Here, point A represents the top of the sledding run, point B represents the bottom of the run, and θ is the angle of depression we want to find.

We can see that AB is the hypotenuse of a right triangle, and the vertical drop of 18.5 yards is the opposite side. We can use the tangent function to relate the opposite side to the adjacent side, which is the horizontal distance of the run:

tan θ = opposite/adjacent

tan θ = 18.5/280

Now we can use a calculator to find the value of the tangent:

θ = tan^(-1) (18.5/280)

θ ≈ 3.84 degrees

Therefore, the angle of depression of the run is approximately 3.84 degrees.

The straight sections each have a length of 100. So, the total distance around the inner lane of the track is 200 + 40pi units

The area of one of the blue half circles can be found using the formula:

Area = pi x radius squared.

The diameter of the circle is given as 40, so the radius is half of that, which is 20.

Therefore, the area of one blue half circle is:
Area = pi x [tex]\frac{20^{2} }{2}[/tex]

Area = 200pi square units
To cover the entire circle, we need both blue half circles. So the total area needed to be covered with grass is:
Total area = 2 x 200pi = 400pi square units
The distance around one of the semicircles at either end of the soccer field can be found using the formula: Circumference = pi x diameter.

Since the diameter is given as 40.

The circumference is:
Circumference = pi x [tex]\frac{40}{2}[/tex]

Circumference = 20pi units

To find the distance around the inner lane of the track, we need to add the lengths of the straight distances (which are 100 each) to the circumference of the two blue half circles.

The circumference of one blue half circle is 20pi, so the total distance around the inner lane of the track is:
Distance = 2 x 100 + 2 x 20pi

Distance = 200 + 40pi units

Therefore, the outer perimeter is approximately 73.20 ft.

Perimeter is the total distance around the outside of a two-dimensional shape. It is calculated by adding up the lengths of all the sides of the shape. The units for perimeter are the same as the units used for the length of the sides. For example, if the sides are measured in feet, the perimeter will be measured in feet as well.

Here,

We need to find the outer perimeter, which means we need to find the perimeter of the shape that includes all the sides of JROP. To do this, we need to find the length of side JO.

Using the Pythagorean Theorem on right triangle JOR, we have:

JO² = JR² + OR²

JO² = 10² + 14²

JO² = 296

JO ≈ 17.20 ft

Now we can find the outer perimeter:

Outer perimeter = JP + PO + OR + RJ + JO

Outer perimeter = 18 + 10 + 14 + 14 + 17.20

Just utilising a line to approximate the value of the function at a given position is what is meant by a function's linear approximation. We recall the idea of the tangent line as soon as we come across a curve (of a function) and a point on it. The value of the function at any point that is extremely close to the provided point can be estimated using the equation of the tangent line if we are able to identify the equation of the tangent line at the given point. Because it uses the tangent line, this idea is sometimes referred to as the tangent line approximation. It is also known as the linear approximation.

The probability that the subject tested negative or did not use marijuana is approximately 0.57.

Probability is a branch of mathematics that deals with the study of random events and their likelihood of occurrence. It is a way of quantifying the uncertainty or randomness associated with an event or an experiment.

In the given question,

To solve this problem, we can construct a table that summarizes the given information:

We are given the following information:

There are 143 subjects with positive test results, of which 20 are false positives.

There are 153 subjects with negative test results, of which 4 are false negatives.

Using this information, we can fill in the table as follows:

The numbers in parentheses are the counts of subjects in each category.

To find the probability that the subject tested negative or did not use marijuana, we need to add the probabilities of the two mutually exclusive events:

Tested negative and did not use marijuana (True Negative): P(True Negative) = 149/296

Tested positive but did not use marijuana (False Positive): P(False Positive) = 20/296

Therefore, the probability that the subject tested negative or did not use marijuana is:

P(Tested Negative or Did not use marijuana) = P(True Negative) + P(False Positive)

= 149/296 + 20/296

= 169/296

≈ 0.57

So, the probability that the subject tested negative or did not use marijuana is approximately 0.57.

=>  A = 240 * 1.0055⁴ⁿ

Consequently, the following is the function displaying the account's worth after t years:

=>  f(t) = 240 * 1.0055⁴ⁿ

We can use the following formula to determine the yearly percentage yield (APY):

=> APY = (1 + r/n)ⁿ - 1

where r equals the 2.2% yearly interest rate.

n is the quantity of times interest is added annually. (4, since interest is compounded quarterly)

When we enter the numbers, we obtain:

=> APY = (1 + 0.022/4)⁴ - 1

Fiinding and interpreting the zero of a rational function involves solving for x when the function equals zero and understanding its significance within the context.

Hello! I understand you want to find and interpret the zero of a rational function, and I'd be happy to help.

The zero of a rational function occurs when the function's value is equal to zero. In other words, a zero is a value of x that makes the function f(x) = 0. To find the zero, you must set the numerator of the rational function equal to zero and solve for x.

It's important to note that the denominator should never equal zero, as this would make the function undefined.

Interpreting the zero helps us understand the behavior of the function and can be useful in various applications.

For instance, the zero might represent a break-even point in a business context or an equilibrium in a physical system. Whether the result makes sense within the context of a specific problem depends on the given scenario and the mathematical relationship between the variables.

To summarize,  Always ensure the denominator is never zero to maintain the function's validity.
