Answers
This question is incomplete, the complete question is;
Katie Ledecky swims the length of a 50m Olympic size pool in 25 seconds and swims the return trip to the starting position in 26 seconds. What are her average velocities during:
a) The first half of the swim?
b) The second half of the swim?
Answer:
a) her average velocities during the first half = 2 m/s
b) her average velocities during the second half = 1.923 m/s
Step-by-step explanation:
Given that;
displacement = 50 m
time taken t = 25 secs
a)
average velocity = displacement / time taken = 50 / 25 = 2 m/s
Therefore her average velocities during the first half = 2 m/s
b)
In the second half;
displacement = 50 m
time taken t = 26 secs
average velocity = displacement / time taken = 50 / 26 = 1.923 m/s
Therefore her average velocities during the second half = 1.923 m/s

If a+b=20 and ab=50
Then find the value of a^2+b^2
Answers
Here,
a+b=20
ab=50
we know that,
[tex]\tt{ (a+b)^2=a^2+b^2+2ab }[/tex] ⠀
According to the question,
[tex]\tt{(20)^2=a^2+b^2+2×50 }[/tex] ⠀
[tex]\tt{ 400=a^2+b^2+100 }[/tex] ⠀
[tex]\tt{ a^2+b^2=400-100 }[/tex] ⠀
[tex]\tt{a^2+b^2=300 }[/tex] ⠀
Answer:
a² + b² = 300
Step-by-step explanation:
a + b = 20 ; ab = 50
(a +b)² = a²+ b² + 2ab
a² + b² + 2ab = (a + b)²
a² + b² + 2*50 = (20)²
a² + b² + 100 = 400
a² + b² = 400 - 100
a² + b² = 300

The area of a circle is increasing at a constant rate of 79 square centimeters per second. At the instant when the radius of the circle is 77 centimeters, what is the rate of change of the radius
Answers
Answer:
0.51cm/s
Step-by-step explanation:
Area of a circle A = πr²
r is the radius
Rate of change of area is expressed as;
dA/dt = dA/dr • dr/dt
dA/dr = 2πr
radius r = 77cm
dA/dt = 79cm²
Get dr/dt
Substitute the given values into the formula
79 = 2π(77)•dr/dt
79 = 154dr/dt
dr/dt = 79/154
dr/dt = 0.51cm/s
Hence the rate of change of the radius is 0.51cm/s

You may need to use the appropriate appendix table to answer this question. The time needed to complete a final examination in a particular college course is normally distributed with a mean of 80 minutes and a standard deviation of 10 minutes. Answer the following questions. (a) What is the probability of completing the exam in one hour or less
Answers
Answer:
The probability of completing the exam in one hour or less is 0.0228.
Step-by-step explanation:
Given: Mean = 80
Standard deviation = 10
To find: The probability of completing the exam in one hour or less.
We have, [tex]\mu=80[/tex] and [tex]\sigma=10[/tex].
Now, the z-value is the sample mean decreased by the population mean divided by the standard deviation.
[tex]z=\frac{\bar{x}-\mu}{\sigma}[/tex]
⇒[tex]z=\frac{60-80}{10}[/tex]
⇒[tex]z=-2[/tex]
Now, [tex]z=\frac{\bar{x}-\mu}{\sigma}[/tex]
⇒[tex]z=\frac{75-80}{10}[/tex]
⇒[tex]z=-0.5[/tex]
Again, [tex]z=\frac{\bar{x}-\mu}{\sigma}[/tex]
⇒[tex]z=\frac{90-80}{10}[/tex]
⇒[tex]z=1[/tex]
Using appropriate appendix table, we get [tex]P(z<-2)=0.0228[/tex].
