The point P = (x, 1/3) lies on the unit circle shown below. What is the value of x in simplest form?
Answers
Answer: - 2squart2/3
Step-by-step explanation:
x^ 2 + y ^ 2 = 1
x ^ 2 + (1/3) ^ 2 = 1 ^ 2
The value of x in simplest form is 2√2/3 units.
What is a circle equation?The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.
The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²
Given that, the point P= (x, 1/3) lies on the unit circle
x²+ y²= 1
x²+ (1/3)²= 1²
x²+1/9=1
x²=1-1/9
x=√8/9
x=2√2/3
Therefore, the value of x in simplest form is 2√2/3 units.

A survey of 50 randomly selected students showed that 38 students buy lunch at school and 12 students bring lunch from home each day. Name the sampling Technique AND if that method is biased or unbiased.
Answers
Answer:
We know that our sample is a group of 50 randomly selected students.
First, we want to know the name of the sampling technique.
There are a lot of sampling techniques, but knowing that the students are selected randomly, we can conclude that this is the simple random sampling technique, where each individual is chosen entirely by chance (so all the students have the same probability of being chosen)
Now we want to know if the method is biased or not,
Always that we use the simple random sampling technique, we will have an unbiased sample.

Step-by-step explanation:
y= −2x − 5
y= 2x − 2
2y = -7
y = -7/2
y= 2x − 2
-7/2 = 2x - 2
2x = -3/2
x = -3/4

Sum of angles in a triangle is 180°, therefore:

x = 180° - 108°

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as
whole numbers or as improper fractions in simplest form.
Answers
Given:
The equation is
[tex]-x+y=8[/tex]
To find:
The x- and y-intercepts.
Solution:
We have,
[tex]-x+y=8[/tex]
Put x=0 in the given equation to find the y-intercept.
[tex]-(0)+y=8[/tex]
[tex]y=8[/tex]
Put y=0 in the given equation to find the x-intercept.
[tex]-x+(0)=8[/tex]
[tex]-x=8[/tex]
[tex]x=-8[/tex]
Therefore, the x-intercept is -8 and the y-intercept is 8.

Answers
Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.
Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):
B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)
Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.
Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.
Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)
Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.
