.
What is Shawn’s kinetic energy?
Answer in units of J.
If the velocity is 2 meters per second. Then the kinetic energy of the Shawn will be 96.2 Joules.
What is kinetic energy?The energy an item has as a result of motion is known as kinetic energy in mechanics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its propulsion until its speed changes.
The kinetic energy is given as,
KE = (mv²)/2
Where m is the mass and v is the velocity.
Shawn and his bike have a total mass of 48.1 kg. Shawn rides his bike 1.5 km in 12.5 min at a constant velocity.
The velocity is given as,
v = 1.5/12.5
v = 0.12 km/min
v = 0.12 x 1000 / 60
v = 2 m/s
Then the kinetic energy of Shawn will be given as,
KE = (48.1 x 2²) / 2
KE = 48.1 x 2
KE = 96.2 J
If the velocity is 2 meters per second. Then the kinetic energy of the Shawn will be 96.2 Joules.

Bob decides to quit his job as a teacher in which he makes $50.000 to open a restaurant. The explicit cost of running his restaurant is $500.000 while the revenue go his business is 525,000. What is his accounting profit or loss? What is his economic profit or loss? What is the implicit cost in this example?
1. Bob's accounting profit is $25,000.
2. Bob's economic loss is $25,000.
3. The implicit cost in this example is the teacher's salary of $50,000 Bob could have got, working as a teacher.
What are explicit and implicit costs?Explicit cost refers to the accounting cost that a business incurs.
Explicit cost is different from implicit cost because implicit cost involves an opportunity cost.
What are accounting profit and economic profit?Accounting profit is the difference between total revenue and explicit cost.
Economic profit is the difference between accounting profit and opportunity cost or the cost of forgone alternatives.
Salary as a teacher = $50,000
Explicit restaurant cost = $500,000
Revenue = $525,000
Accounting profit = $25,000 ($525,000 - $500,000)
Economic loss = -$25,000 ($525,000 - $500,000 - $50,000)
Thus, whereas Bob makes an accounting profit of $25,000, he actually incurs an economic loss of $25,000 by forgoing his teacher's salary.

a report on high school graduation stated that 85 percent of high school students graduate. suppose 3 high school students are randomly selected from different schools. what is the probability that none will graduate?
The probability that exactly none will graduate is [tex]0.003375[/tex].
What is probability?
Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes.
Step-by-step explanation:
Let [tex]X[/tex] be the random variable for the number of students who graduate.
Binomial distribution theorem tells that, [tex]P(X=x)=C(n , x)p^xq^{n-x}[/tex].
Here [tex]p=[/tex]probability of success on a single trial, [tex]q=[/tex]probability of failure on a single trial, [tex]n=[/tex] number of trials.
Given that [tex]p=0.85, q=1-p=1-0.85=0.15[/tex] and [tex]n=3.[/tex]
[tex]P(X=x)=C(3 , x)0.85^x0.15^{3-x}[/tex]
When [tex]3[/tex] students are randomly selected the probability that exactly none will graduate is given by,
[tex]P(X=0)=C(3 , 0)0.85^00.15^{3-0}[/tex]
[tex]P(X=0)=\frac{3!}{0!(3-0)!} 0.15^{3}[/tex]
[tex]P(X=0)=0.15^{3}[/tex]
[tex]P(X=0)=0.003375[/tex]

Answer:
Part A:
[tex]y=-x+8[/tex]Part B:
[tex]y=x+4[/tex]Step-by-step explanation:
Part A:
Remember that two parallel lines have the same slope. This way, we can conclude that the slope of this particular line is:
[tex]m_a=-1[/tex]Since we already know that this line passes through point (2,6), we can use this point, the slope we've found and the slope-point form to get an equation for the line:
[tex]\begin{gathered} y-6=-1(x-2) \\ \rightarrow y-6=-x+2 \\ \\ \Rightarrow y=-x+8 \end{gathered}[/tex]Therefore, we can conclude that the equation of this line is:
[tex]y=-x+8[/tex]Part B:
Remember that the product between the slopes of two perpendicular lines is -1. This way, we'll have that:
[tex]\begin{gathered} -1\times m_2=-1 \\ \\ \Rightarrow m_2=1 \end{gathered}[/tex]Since we already know that this line passes through point (2,6), we can use this point, the slope we've found and the slope-point form to get an equation for the line:

3. The diameter of a spherical balloon shrinks to one-half of its original size.How does this affect the volume?Hint: Test two scenarios and compare the volumes! Show your work!!A. The volume is cut in halfB. The volume doublesC. The volume is 1/8 the original volumeD. The volume is 1/4 the original volume
Answer:
C. The volume is 1/8 the original volume
Explanation:
Step 1. To find how the volume changes if the diameter is reduced to one-half of the original size, we will test two scenarios:
• In the first scenario, the diameter will be 2, and in the second scenario, the diameter will be one-half of 2 which is 1.
We will find the volume for these two cases and see how it changes.
Step 2. For a diameter of d=2.
If the diameter is 2, the radius is:
[tex]\begin{gathered} r=d/2 \\ r=2/2 \\ r=1 \end{gathered}[/tex]Using the volume formula for a sphere:
[tex]V=\frac{4\pi}{3}r^3[/tex]In this case:
[tex]V=\frac{4\pi}{3}(1)^3[/tex]We will call this volume, V1:
[tex]V_1=\frac{4\pi}{3}[/tex]Step 3. Now we will find the volume for the second case in which the diameter is d=1.
The radius is:
[tex]\begin{gathered} r=d/2 \\ r=1/2 \\ \end{gathered}[/tex]Using the same formula for the volume:
[tex]V=\frac{4\pi}{3}(\frac{1}{2})^3[/tex]Solving the operations:
[tex]V=\frac{4\pi}{3}(\frac{1}{8})^[/tex]We will call this V2:
[tex]V_2=\frac{4\pi}{3}(\frac{1}{8})^[/tex]Step 4. As you can see, the first part of the previous expression is V1:
[tex]\begin{gathered} V_{1}=\frac{4\pi}{3} \\ V_2=\frac{4\pi}{3}(\frac{1}{8}) \end{gathered}[/tex]Therefore:
[tex]V_2=V_1(\frac{1}{8})[/tex]The second volume is the first volume multiplyed by 1/8 ⇒ it is 1/8 of the original volume.
Answer:
C. The volume is 1/8 the original volume

Pens cost 20p each.
Rulers cost 60p each.
Saj buys some pens and some rulers.
He buys 8 rulers.
The total cost is £10
How many pens does he buy?
Answer:
26 pens
Step-by-step explanation:
Let P and R be the numbers of Pens and Rulers Saj purchases.
The cost of P Pens and R Rulers:
Pens = P(20p)
Rulers = R(60p)
P(20p) + R(60p) = £10
P(0.20) + R(0.60) = 10
R = 8
P(0.20) + (8)*(0.60) = 10
P(0.20) + 4.8= 10
P(0.20) = 5.2
P = (5.2/0.20)
P = 26 pens
CHECK:
8 Rulers = 8*(60p) = 480p
26 Pens = 26*(20p) = 520p
Total = £10
