The terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0 is 1.
What is a terminal point?The terminal point of a circle or circular path is the measure of the angle in degrees or radians over the circle, at the endpoint on the coordinate plane.
The equation for the angle is given as,
[tex]\theta=\dfrac{\pi}{4}\rm radians[/tex]
The terminal point and tan 0 has to be found out.As, the value of pi is 180 degrees. Put this value in the above expression as,
[tex]\dfrac{\pi}{4}=\dfrac{180}{4}=45^o[/tex]
Now, as the rotation of it clockwise from the x-axis in quadrant 1to get the degrees of the angle to the terminal point.
Let this is unit circle with radius 1. Therefore, from the unit circle attached below,
[tex]y=\sin(45)\times1=\dfrac{2}{\sqrt{2}}\\x=\cos(45)\times1=\dfrac{2}{\sqrt{2}}[/tex]
[tex]\tan (45)=1[/tex]
Hence, the terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0 is 1.

A package of screen protectors for an iPhone
are priced $12.99. What is the price of the screen
protectors after 6% sales tax?
Answer: $13.77
Step-by-step explanation:
To get the final price for the screen protectors, we have to calculate the value of the tax and add to the current price of the screen protector.
The sales tax will be:
= 6% × $12.99
= 6/100 × $12.99
= 0.06 × $12.99
= $0.7794
The price of the screen protector will now be:
= $12.99 + $0.7794
= $13.7694
= $13.77

Answer:
jeez, one lazy person must you be if you dont have time to finish this xD
answer is 181
Step-by-step explanation:
well first divide the two objects, a triangle, and a rectangle. Now we have no idea what the bottom of the triangle is so lets calculate that. 18 - 2 -5 = 11
so the triangles dimesions are a10, b11. Now we have to implement the pythagorem theroem since it doesnt give us the side "c". its a simple a^2+b^2=c^2. so side "c" is 14.866. now we can calculate and add everything together. so 18*7=126. and the triangles area is 55. so add 126+55 and viola. you get 181. Im a bit skeptical that i got something wrong but i hope its all correct. hope this helps!
Explain how to simplify the rational expression x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8. (be sure to include the simplified rational expression)
Answer:
267x2 -8x -8 where
x=- 4± 2√ 538/267
Step-by-step explanation:
x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8
= x2 -89x2 - 16x2 - 163x2 - 2x+ 10 x + 8
= -267x2+8x +8
= 267x2 -8x -8
First the like terms are arranged and then added . All the co efficients of x2 are added and x are added separately.
Using the quadratic equation to find the value of x
a= 267 , b= -8 and c= -8
x= -b±√b²- 4ac/ 2a
x= -8±√64 +8544/534
x= -8±√8608/534
x=-8±√ 2 x 2 x 2 x 2 x 2 x 269/534
x=-8± 4√ 2 x 269/534
x=- 4± 2√ 2 x 269/267
x=- 4± 2√ 538/267

The variable x is the hypotenuse, and the value of x in the right triangle is 24.8
How to determine the value of x?The complete question is a right triangle, where x is the hypotenuse.
So, the equation of x is:
[tex]x^2 = 19^2 + 16^2[/tex]
Evaluate the sum of exponents
[tex]x^2 = 617[/tex]
Take the square root of both sides
x = 24.8
Hence, the value of x is 24.8

Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.
Chloe was given a large box of 36 chocolates for her birthday. If she eats exactly 2 chocolates each day, how many chocolates would Chloe have remaining 8 days after her birthday?
Answer:
20 chocolates
Step-by-step explanation:
I got 20 chocolates as my answer because I multiplied the 2 chocolates eaten each day by the 8 days. She eats 2 chocolates each day for 8 days. 8x2=16. Then, I took the 36 chocolates and subtracted 16 chocolates eaten to get the answer of how many chocolates are left. 36-16=20. Therefore, Chloe has 20 chocolates.
Chloe has 20 chocolates remaining 8 days after her birthday.

Suppose a city with population 600,000 has been growing at a rate of 3% per year. If this rate continues, find the population of this city in 22 years.
Answer:
The answer should be around 1,149663 (Rounded off to the nearest whole number. Also if a population has a remainer you usually add it as 1. This is because these are people)
Step-by-step explanation:
First step involves listing the formulas being used:
600,000= population, 0.03= growth rate 22years= period
Therefore, we take the 600,000 and multiply by 1+0.03 ^22(to the power of 22 or period)
So, 600,000(1+0.03)^22
=1,149662.045 /1,149663

A spinner is divided into equal sections, each labeled with a number between 1 and 5? Over the course of 150 spins, what is the best estimate of how many times you would expect that the hand of the spinner will stop on a 3? Need it kinda fast but take your time.
Answer:
30 times
Step-by-step explanation:
The computation of the number of times that expected to stop on 3 is as follows:
Since there are 150 spins
And, each labeled with a number that lies between 1 and 5
So the number of times should be
= 150 ÷ 5
= 30 times
Hence, the number of times would be 30
