Answer:
UD = 20
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
12² = 7.2(7.2 + CD)
144 = 7.2² + 7.2CD
144 = 51.84 + 7.2CD ( subtract 51.84 from both sides )
92.16 = 7.2CD ( divide both sides by CD )
12.8 = CD
Thus
UD = UC + CD = 7.2 + 12.8 = 20

When Tracey pours all the water from the smaller 5-inch cube container into the larger 7-inch cube container, the water will be approximately 7 inches deep in the larger container.
To find out how deep the water will be in the larger container, we need to consider the volume of water transferred from the smaller container. Since both containers are cube-shaped, the volume of each container is equal to the length of one side cubed.
The volume of the smaller container is 5 inches * 5 inches * 5 inches = 125 cubic inches.
When Tracey pours all the water from the smaller container into the larger container, the water completely fills the larger container. The volume of the larger container is 7 inches * 7 inches * 7 inches = 343 cubic inches.
Since the water fills the larger container completely, the depth of the water in the larger container will be equal to the height of the larger container. Since all sides of the larger container have the same length, the height of the larger container is 7 inches.
Therefore, the water will be approximately 7 inches deep in the larger container.

Answer:
The answer to your problem is, 84$
Step-by-step explanation:

48 × $5.25 = $252.00
If Max were a non-smoker, she would pay annually:
48 × $3.50 = $168.00
But if her insurance company considers a smoker who quits to be a non-smoker, then by quitting, Max could save. M = Money

true or false: if you are given a graph with two shiftable lines, the correct answer will always require you to move both lines.
False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.
In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.
When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.
In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.
However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.
Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.

The number of milligrams D (ht) of a certain drug that is in a patient's bloodstream h hours after the drug is injected is given by the following function.
D(h) = 25e -0. 4
When the number of milligrams reaches 6, the drug is to be injected again. How much time is needed between injections?
Round your answer to the nearest tenth, and do not round any intermediate computations.
The time is needed between injections is 3.6 hours, i.e., the drug is to be injected again when the number of milligrams reaches 6 mg.
We have the exponential function of number of milligrams D (ht) of a certain drug that is in a patient's bloodstream h hours after the drug is injected is
\(D(h)=25 {e}^{ - 0.4 h}\)
We have to solve for h (the numbers of hours) that would have passed when the D(h) (the amount of medication in the patient's bloodstream) equals 6 mg in order to know when the patient needs to be injected again.
\(6 = 25 {e}^{ - 0.4h} \)
\( \frac{6}{25} = \frac{25}{25} {e}^{ - 0.4h} \)
\(0.24= {e}^{ - 0.4h} \)
Taking logarithm both sides of above equation , we get,
\( \ln(0.24) = \ln( {e}^{ - 0.4h)} \)
Using the properties of natural logarithm,
\( \ln(0.24) = - 0.4h\)
\( - 1.427116356 = - 0.4h\)
\(h = \frac{1.42711635}{0.4} = 3.56779089\)
=> h = 3. 6
So, after 3.6 hours, the patient needs to be injected again.

schedules the processor in the order in which they are requested. question 25 options: first-come, first-served scheduling round robin scheduling last in first scheduling shortest job first scheduling
Scheduling the processor in the order in which they are requested is "first-come, first-served scheduling."
The scheduling algorithm that schedules the processor in the order in which they are requested is known as First-Come, First-Served (FCFS) scheduling. In FCFS scheduling, the processes are executed based on the order in which they arrive in the ready queue. The first process that arrives is the first one to be executed, and subsequent processes are executed in the order of their arrival.
FCFS scheduling is simple and easy to understand, as it follows a straightforward approach of serving processes based on their arrival time. However, it has some drawbacks. One major drawback is that it doesn't consider the burst time or execution time of processes. If a long process arrives first, it can block the execution of subsequent shorter processes, leading to increased waiting time for those processes.
Another disadvantage of FCFS scheduling is that it may result in poor average turnaround time, especially if there are large variations in the execution times of different processes. If a long process arrives first, it can cause other shorter processes to wait for an extended period, increasing their turnaround time.
Overall, FCFS scheduling is a simple and fair scheduling algorithm that serves processes in the order of their arrival. However, it may not be the most efficient in terms of turnaround time and resource utilization, especially when there is a mix of short and long processes. Other scheduling algorithms like Round Robin, Last In First Scheduling, or Shortest Job First can provide better performance depending on the specific requirements and characteristics of the processes.

Answer:
im doing work to im going to fail
Step-by-step explanation:
calculate the average height above the x-axis of a point in the region 0≤y≤x2, for 0≤x≤25.
The average height above the x-axis of a point in the region \(0\leq y\leq x^2\), for 0≤x≤25 using definite integral is 208.33 units.
To calculate the average height above the x-axis of a point in the region \(0\leq y\leq x^2\), for 0 ≤ x ≤ 25, we need to find the average value of y over this range.
The equation y = x² represents a parabola that opens upwards. To find the average height, we need to integrate the function y = x² over the given range and then divide by the length of the range.
Let's calculate it step by step:
Calculate the definite integral of y = x² with respect to x over the range 0 to 25:
∫[0,25] \(x^{2}\) dx = \([x^3/3]\) evaluated from 0 to 25
\(= (25^3/3) - (0^3/3)\\= (25^3/3)\\= 16666.67\)
Calculate the length of the range:
Length = 25 - 0 = 25
Divide the definite integral by the length of the range to find the average height:
\(Average height = (25^3/3) / 25\\= (25^2/3)\\= 208.33\)
Therefore, the average height above the x-axis of a point in the region \(0\leq y\leq x^2\), for 0 ≤ x ≤ 25, is approximately 208.33 units.
