As shown in the figure below, Luis walks 40 m toward his truck. He notices he forgot his keys, so he returns
back to his house. His total travel time is 95 s.
40 m
40 m
What is Luis's average velocity over the 95 s period?
Answer:
Velocity = 0
Speed = 0.84
Step-by-step explanation:
Khan Academy
Luis's average velocity over the 95 sec period is 0 m/s.
Given that, Luis walks 40 m toward his truck. He notices he forgot his keys, so he returns back to his house.
What is the average velocity?Magnitude of average velocity is always less than or equal to the average speed because displacement is always smaller than or equal to distance.
Average Velocity = Total time / Total Displacement
It is a vector quantity and has units of m/s.
Here, total time = 95 sec and displacement = 0 meter
Now, average velocity = 95/0
= 0 m/s
Therefore, Luis's average velocity over the 95 sec period is 0 m/s.

Given w= √ 2(cos(pi/4)+isin(pi/4)) and z=2(cos (pi/2)+i sin (pi/2)) what is w-z expressed in polar form?
Answer:
It is B.
Step-by-step explanation:
Edge2021
[tex]w -z =\sqrt{2}(cos(\frac{3\pi}{4} )+i~sin(\frac{3\pi}{4} ))[/tex]
What is complex number?"The number of the form a + ib where a, b are real numbers and [tex]i=\sqrt{-1}[/tex] "
What is polar form of complex number?"The polar form of complex number z = x + iy is [tex]z=r~(cos\theta+i~sin\theta)[/tex] where [tex]r=\sqrt{x^{2} +y^{2} }[/tex] and [tex]\theta=tan^{-1}(\frac{y}{x} )[/tex]"
For given question,
We have been given two complex numbers in polar form.
[tex]w=\sqrt{2}(cos(\frac{\pi}{4} )+i~sin(\frac{\pi}{4} ))[/tex] and [tex]z=2(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))[/tex]
We simplify above complex numbers.
[tex]w=\sqrt{2}(cos(\frac{\pi}{4} )+i~sin(\frac{\pi}{4} )) \\\\w=\sqrt{2}(\frac{1}{\sqrt{2} } +i~ \frac{1}{\sqrt{2} } ) \\\\w=1+i[/tex]
And the second complex number is,
[tex]z=2(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))\\\\z=2(0+i~1)\\\\z=0+2i[/tex]
Now if we find the value of w - z
⇒ w - z = (1 + i) - (0 + 2i)
⇒ w - z = 1 - i
Now we find the polar form of complex number.
[tex]r=\sqrt{1^{2} +(-1)^{2} } \\\\r=\sqrt{2}[/tex]
And the value of [tex]\theta[/tex] would be,
[tex]\theta=tan^{-1}(\frac{-1}{1} )\\\\\theta=tan^{-1}(-1)\\\\\theta=\frac{3\pi}{4}[/tex]
So, w - z in the polar form would be [tex]1+i=\sqrt{2}(cos(\frac{3\pi}{4} )+i~sin(\frac{3\pi}{4} ))[/tex]
Therefore, [tex]w -z =\sqrt{2}(cos(\frac{3\pi}{4} )+i~sin(\frac{3\pi}{4} ))[/tex]

12. e* - In 2x = 3.7
I
Answer:
x = 0.05
x = 1.57
Step-by-step explanation:
The given equation is:
[tex]e^x-\ln 2x = 3.7[/tex]
Moving all terms to the left side:
[tex]e^x-\ln 2x - 3.7=0[/tex]
Now we define a function:
[tex]y=f(x)=e^x-\ln 2x - 3.7[/tex]
The solutions of the equation are the values of x such that y=0.
Since the function cannot be solved by algebraic methods, we use a graphing tool.
Those points where the graph crosses the x-axis are solutions of the equation.
Please refer to the graph in the figure below.
We can clearly identify there are two solutions at
x = 0.05
x = 1.57

Normal vision is called 20-20 vision. These numbers are actually a ratio—a comparison of the distance you can see to the distance a normal-sighted person can see. For example, a person with 20-30 vision can see from a distance of 20 feet what a person with 20-20 vision can see from a distance of 30 feet. Based on this knowledge, explain what the following numbers mean regarding vision.
a. 20-100
b. 20-40
A person with 20-40 vision can see up to 30 feet and a person with 20-100 vision can see up to 200 feet (No-one can see that far unless they are not human or unless they are a spirit.)

A. 3(8+12)
B. 4(6+9)
C. 12(2+3)
D. 6(4+6
Answer:
D
Step-by-step explanation:
The product of the greatest common factor and a sum is 12 (2 + 3).
Option C is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
24 + 36
We have the following cases:
2 (12 + 18)
3 (8 + 12)
4 (6 + 9)
6 (4 + 6)
12 (2 + 3)
Now,
The greatest common factor.
12 x 2 = 24
12 x 3 = 36
Thus,
12(2 + 3) is the product of the greatest common factor and a sum of (2 + 3).
