after how many seconds is needed for a thrown ball to reach a 14-m distance if it's distance is given by the relation d=10+40t-5t? (t=time in seconds)
Answers
Answer:
Time, t = 0.1143 seconds.
Step-by-step explanation:
Given that distance, d = 14m
From the equation;
d = 10 + 40t - 5t
d = 10 + 35t
Substituting the value of distance;
14 = 10 + 35t
35t = 14 - 10
35t = 4
t = 4/35
t = 0.1143 seconds.
The time needed for the ball to reach the 14-m distance is 0.1143 seconds.
The thrown ball will reach a 14-m distance after 0.114 seconds.
The relation given is:
d = 10+40t-5t
where, d = 14
In this case, we've to put the value of d into the relation and this will be:
d = 10+40t-5t
14 = 10 + 40t - 5t
Collect like terms
40t - 5t = 14 - 10
35t = 4
Divide both side by 35
35t/35 = 4/35
t = 0.114 seconds.

Calculate the present value of a four-period annuity of $200 per year that begins two years from today if the discount rate is 9%?
Please give me full answers with showing all the formulas and workings .
Answers
The present value of a four-period annuity of $200 per year, begins two years from today, can be calculated using the present value of an annuity formula.With a discount rate of 9%, the present value approx $703.30.
To calculate the present value of the annuity, we use the formula PV = C * [1 - (1 + r)^(-n)] / r, where PV represents the present value, C is the cash flow per period, r is the discount rate, and n is the number of periods.
In this case, C = $200, r = 9% (0.09 as a decimal), and n = 4. We substitute these values into the formula: PV = $200 * [1 - (1 + 0.09)^(-4)] / 0.09.
Next, we simplify the formula: PV = $200 * [1 - 0.683013455] / 0.09.
Evaluating the expression inside the brackets, we have PV = $200 * 0.316986545 / 0.09.
Performing the division, we find that the present value is approximately $703.30.
Therefore, the present value of the four-period annuity is approximately $703.30 when the discount rate is 9%.

Program Evaluation Review Technique (PERT)/Critical Path Method (CPM) and Gantt charts are mutually exclusive techniques. True or False?
Answers
False. Program Evaluation Review Technique (PERT)/Critical Path Method (CPM) and Gantt charts are not mutually exclusive techniques. In fact, they are often used together in project management to plan, schedule, and manage complex projects.
PERT/CPM is a network-based project management technique that focuses on identifying and sequencing activities, estimating their durations, and determining the critical path—the sequence of activities that determine the project's overall duration. PERT/CPM helps in analyzing the project timeline, identifying dependencies between tasks, and determining the most efficient way to complete the project.
On the other hand, Gantt charts are visual representations of project schedules that use horizontal bars to represent tasks, their durations, and their interdependencies. Gantt charts provide a graphical overview of the project timeline, allowing project managers and team members to see task durations, milestones, and dependencies at a glance. They also facilitate tracking progress and identifying potential scheduling conflicts.
While PERT/CPM focuses on the critical path and task dependencies, Gantt charts provide a broader view of the project schedule and its progress. Both techniques offer valuable insights and are often used in conjunction to effectively plan and manage projects.
Therefore, PERT/CPM and Gantt charts are complementary tools rather than mutually exclusive techniques in project management.

Since we read from left to right, when we see a price, we process the number of dollars before the number of cents. This is why so many prices end in a.99.
What is the meaning of the word price?A price is a numerical value that indicates how much money or other items of value an individual or a company must pay to acquire or consume a good or service. A price is the amount of money or goods exchanged for a good or service. It may also refer to the cost of a good or service. Consumers are often wary of prices since they will affect their finances.Price is a term used in economics and business to describe the monetary value of a good or service. It's usually the sum of a good or service's cost plus a profit. The price of a good or service is influenced by many factors, including supply and demand, competition, production costs, and government regulations.

nine new employees, two of whom are married to each other, are to be assigned nine desks that are lined up in a row. if the assignment of employees to desks is made randomly, what is the probability that the married couple will have adjacent desks? (round your answer to the nearest tenth of a percent.)
Answers
The probability that the married couple will have adjacent desks is 0.22.
Fundamental Principle of Counting, also called the counting rule, is the method to count how many ways multiple independent events can occur.
Thus, by Fundamental Principle of Counting, the number of possible arrangements where the married coupe has adjacent desks is 80640.
= 8 x 7! x 2
= 80640
Ans the total number of possible arrangements is 362880.
= 9!
= 362880
Probability is defined as the likeliness of an event to occur. The probability of any event to occur ranges from 0 to 1, and the sum of all the probabilities of all the events happening is 1.
probability = desired outcome / total outcomes
probability = 80640/362880

What are 3 ways to name a triangle?
Answers
The solution below describes the ways of naming a triangle
What are Triangles?
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.
Solution:
Naming of a Triangle can be divided into two categories having three subparts:
1. On the basis of Angle
- Acute Angle Triangle - All the angles of a triangle are less than 90 degrees.
- Obtuse Angle Triangle - One of the angles of a triangle is greater than 90 degrees.
- Right Angle Triangle - One angle measures 90 degrees and the other two angles are acute.
2. On the basis of Side
- Equilateral Triangle - All of the sides of an equilateral triangle are the same length. In such a circumstance, each of the inner angles will be 60 degrees. An equilateral triangle is also known as an equiangular triangle since its angles are all the same.
- Isosceles Triangle - Two of the three sides of an isosceles triangle are equal in length. As a result, the angles opposing the equal sides are equal. An isosceles triangle, in other words, has two equal sides and two equal angles.
- Scalene Triangle - A scalene triangle has sides of varying lengths. In such a triangle, no side will be the same length as any of the other sides. All of the inner angles of a scalene triangle are also varied.

Usain Bolt ran the 2012 Olympic 100-meter race in 9.63 seconds. If he runs at this rate on a road with a speed limit of 25 miles per hour, how will his speed compare to the speed limit? Justify your answer. (25 mi/hr = 40,234 meters/hr)
Answers
Answer: Since the Usain Bolt ran the 2012 Olympic 100- meter race in 9.63 seconds compared to 40,234 meters in one hour,
Since there is 3600 seconds in a hour, divide 3600 by 9.63 and you will get 373.8317757.
3600 / 9.63 = 373.8317757
Now multiply the 100 meters by that number for the total distance it would be if Usain Bolt ran the 100 meter race at the same rate for an hour,
100 * 373.8317757 = 37383.17757 meters in one hour.
Now to compare this with the 25 mile one that is coverted to 40,234 meters in 25 miles an hour.
40,234 - 37383.17757 = 2850.82243 meters in comparison.
The correct answer would be 2850.82243 or rounded as 2850 meter difference.

I am trying to find the value of x, y, and z.
Answers
Answer:
\(\begin{gathered} x=\sqrt[]{35}=5.62 \\ y=\sqrt[]{60}=7.75 \\ z=\sqrt[]{84}=9.17 \end{gathered}\)Explanation: We need to find x y z, three missing sides:
From the given triangle, we can form three equations, using the Pythagorean theorem as:
\(\begin{gathered} (1)\rightarrow5^2+x^2=y^2 \\ (2)\rightarrow7^2+x^2=z^2 \\ (3)\rightarrow z^2+y^2=(7+5)^2=12^2 \\ \end{gathered}\)Solution by substitution:
Substituting (1) in (3) gives:
\(\begin{gathered} z^2+5^2+x^2=12^2 \\ z^2+25+x^2=144 \\ z^2+x^2=144-25=119 \\ z^2+x^2=119\rightarrow(4) \end{gathered}\)We have reached equation (4), solving for z in equation (4), and then substituting it into equation (2) gives:
\(\begin{gathered} 7^2+x^2=119-x^2\rightarrow2x^2=119-49=70 \\ \therefore\rightarrow \\ x=\sqrt[]{\frac{70}{2}}=\sqrt[]{35}=5.916 \end{gathered}\)Plugging this x into equation (4) gives:
\(\begin{gathered} z^2+(\sqrt[]{35})^2=119\rightarrow z^2=119-35=84 \\ \therefore\rightarrow \\ z=\sqrt[]{84}=9.165 \\ \\ \end{gathered}\)Now that we have x and z, we plug x it into equation (1) and we get:
\(\begin{gathered} 5^2+(\sqrt[]{35})^2=y^2 \\ \therefore\rightarrow \\ y^2=25+35=60 \\ y=\sqrt[]{60}=7.75 \end{gathered}\)x y z respectively are:

Determine the equation of the circle with center (9, —8) containing the point (1,7).
Answers
(x - 9)^2 + (y + 8)^2 = 17^2
Step by step solved:
The equation of a circle with center (a,b) and radius r is given by:
(x - a)^2 + (y - b)^2 = r^2
We are given the center of the circle as (9, -8), and we know that it contains the point (1,7). Let's call the radius of the circle r.
Substituting the given values into the equation, we get:
(1 - 9)^2 + (7 - (-8))^2 = r^2
(-8)^2 + (15)^2 = r^2
64 + 225 = r^2
289 = r^2
r = √289
r = 17
Therefore, the equation of the circle is:
(x - 9)^2 + (y + 8)^2 = 17^2

over the next 30 days, how many days will your favorite radio or tv station correctly forecast whether it will be cloudy?
Answers
It is difficult to accurately predict the number of days a favorite radio or TV station will correctly forecast whether it will be cloudy over the next 30 days.
Forecasting weather accurately is a challenging task, and even the most advanced weather models are subject to errors. The accuracy of a station's forecasts depends on various factors such as the quality of their data sources, the skill and experience of their forecasters, and the complexity of the weather patterns in the region. Therefore, it is not possible to determine the exact number of days a station will make correct forecasts about whether it will be cloudy or not. However, it is important to note that modern weather forecasting has come a long way in recent years, and many stations now provide fairly accurate predictions. It is always a good idea to consult multiple sources and use personal judgment when making plans based on weather forecasts.
