In the accompanying diagram of a unit circle, the ordered pair (x, y) represents the point where the terminal side of θ intersects the unit circle. If θ = 150°, what is the value of x?
Answer:
(-[tex]\sqrt{3\\}[/tex]/2,1/2);(-x,y)
Step-by-step explanation:
use the 1, root 3, 2 trick. 150's reference angle is 30 as q2 = 180-x
1 is the opposite here, 2 is always hypotenuse, root 3 is adjacent here
x value is based on cos = CAH
it's minus because in q2 angles are (-x,y)

The table shows selected values of a piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞). Which of the following statements are true? Select all that apply.
help pls
Answer: B D F
Step-by-step explanation:
The statement (B), statement (D), statement (F) are true if piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞).
What is piecewise function?A piecewise function is one that has several curve parts in its graph.
It means that, based on the value of the input, it has countless definitions.
A piecewise function, in other words, performs differently depending on the input.
We have given a data for a piecewise function.
From the data:
[tex]\rm \lim_{n \to 3^+} f(x) = 5[/tex]
[tex]\rm \lim_{n \to 3^-} f(x) = 6[/tex]
[tex]\rm \lim_{n \to 2^+} f(x)[/tex] Does not exist because [tex]\rm \lim_{n \to 3^+} f(x)[/tex] and [tex]\rm \lim_{n \to 3^-} f(x)[/tex] are not equal.
Thus, the statement (B), statement (D), statement (F) are true if piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞).

Add the numbers and divide by the amount of numbers and get 6.8
Answer: 6.8.
Step-by-step explanation: When finding the mean of a data set, you need to add all the numbers of the set, and then divide the answer by however many numbers you have on the data set. The work is done below:
14 + 7 + 2 8 + 3 = 34.
34 / 5 = 6.8, because there are 5 numbers in the data set.

A tank in the shape of a hemisphere has a radius of 5 feet. If the liquid that fills the tank has a density of 51.6 pounds per cubic foot, what is the total weight of the liquid in the tank, to the nearest full pound?
Tthe total weight of the liquid in the tank, to the nearest full pound is 13,514 pounds.
What is the total weight of the liquid in the tank?The first step is to determine the volume of the tank.
Volume of a hemisphere = Volume of a hemisphere = (2/3) x (π) x (r³)
π = 22/7r = radius2/3 x 5³ x 22/7 = 261.91 ft³

PLEASE HELP what is the remainder if 3⁷³ is divided by five please and BRAINLIEST
Answer:
3
Step-by-step explanation:
3^1 = 3, 3^2 = 9, 3^3 =27, 3^4 =81,
3^5 = 243, etc. We see that the last digits of the powers of 3 are 3, 9, 7, and 1. If we continue this pattern, the last digit of 3^73 is 3. So if 3^73 is divided by 5, the remainder is 3.

at a basketball game, a vender sold a combined total of 166 sodas and hot dogs. The number of hot dogs sold was 54 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
The best way to solve these sorts of problems that involve two factors of unknown quantities but with certain properties is to use equations:
Let's set some variables
h: # of hot dogs solds: # of sodas soldNow based on the information given by the question, let's set up some equations:
vender sold a combined total of 166 sodas and hot dog⇒ [tex]s + h = 166[/tex]
number of hot dogs sold was 54 less than the number of sodas sold⇒ h = s - 54
Now lets put the equation together
s + h = 166 -- equation 1
h = s - 54 -- equation 2
Solve:
Plug the value of h from equation 2 into equation 1
s + (s - 54) = 166
2s - 54 = 166
2s = 220
s = 110 -- equation 3
Plug the value of s from equation 3 into equation 2
h = 110 - 54 = 56
h = 56
Therefore:
number of sodas sold: 110number of hot dogs sold: 56Hope that helps!

The width of a rectangle with the area 55in^2 depends on its length. Write the formula that describes the width of the rectangle as a function of its length.
The width of the rectangle as a function of its length is w = 55/l
How to find the area of a rectangle?The formula for finding the area of a rectangle is expressed as:
A = lw
where
l is the length
w is the width of the rectangle
Given that A = 55 square inches, then;
55 = lw
w = 55/l
Hence the width of the rectangle as a function of its length is w = 55/l
