Find the point on the terminal side of θ = negative three pi divided by four that has an x coordinate of -1. Show your work for full credit.
Answer:
(-1,-1)
Step-by-step explanation:
x = rcos(theta)
-1 = r cos(-3pi/4)
-1 = r(-sqrt(2)/2)
r = sqrt(2)
y = rsin(theta)
y = sqrt(2)sin(-3pi/4)
y = -1
(-1,-1)

Answer:
x+y
Z2
1/2xy
Step-by-step explanation:
(x+y)^2 finds the area of the outer square by squaring its side length.
z^2 + 4 (1/2xy) finds the area of the outer square by adding the area of the inner square and the four triangles.

Factor the polynomial.
216x^3-64
math help pls, will reward.
Answer:
6. B
7. A
8. A
9. A
Step-by-step explanation:
6. As x approaches ∞ (as x goes to the right), y approaches ∞ (y goes up).
7. f(x) = -x⁴ + 5x³ − 2x + 5
The leading coefficient is negative, and the highest power is 4 which is even. So as x→-∞, f(x)→-∞, and as x→∞, f(x)→-∞.
8. The roots are 3, -4, and 1, so the polynomial is:
f(x) = (x − 3) (x − (-4)) (x − 1)
f(x) = (x − 3) (x + 4) (x − 1)
9. The roots are 0 (multiplicity of 1), 1 (multiplicity of 2), and -2 (multiplicity of 2).
f(x) = (x − 0)¹ (x − 1)² (x − (-2))²
f(x) = x (x − 1)² (x + 2)²

Sandy is 6 inches taller than Marie. If Marie
is an odd number of inches tall, which of the
following could be Sandy's height?
Answer:
# Theoretically, the height of Sandy must be an odd numbers, and not less than 5.
It may be: 7,9,11,....
# However, as 1 inch for the height of a girl is too funny - Marie can not have a height of 1 inch ( only in the case Marie and Sandy are the names of the toys!) - you should choose the number that fits best to the human height.

PLEASE MARK BRAINIEST!!
The required value of cos θ is approximately -0.95.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
We are given that sin θ = -0.31 and π < θ < 3π/2.
Since sin θ = -0.31 is negative, we know that θ is in the third quadrant.
Using the identity 2θ + 2θ = 1,
We can rewrite it as:
2θ = 1 - 2θ.
Squaring both sides, we get:
4θ² = 1 - 4θ + 4θ²
Simplifying, we get 8θ = 1, which means θ = 1/8π.
Since θ is in the third quadrant, we have cos θ < 0.
Using the identity cos² θ + sin² θ = 1, we can solve for cos θ as follows: cos² θ = 1 - sin² θ
cos² θ = 1 - (-0.31)²
cos² θ = 0.9039
cos² θ ≈ -0.95
Therefore, the value of cos θ is approximately -0.95.

Pi ends after how many decimal places?
Answer:
31.4 trillion decimal places but no one really knows how many decimal places there are. 31.4 trillion decimal places is a world record set by google
Step-by-step explanation:
Answer:
`31.4 trillion decimal places.
Explanation:
As far as we know Google found out that there is about 31.4 trillion decimal places which is rounded to 3.14. Google is not 100% accurate though, Pi is a mathematical number that never ends so we just use what we know which is 3.14. Pi is an ideal that in numerical terms can be approached, but never reached. In order to calculate Pi simply involves taking any circle and dividing its circumference by its diameter. William Jones is the "founder" of Pi in 1706. Jones was a British little-known mathematics teacher, Jones was the first person to use a symbol to represent the platonic concept of Pi.

Pentagon ABCDE is rotated 90 degrees counterclockwise about the origin to form pentagon A’ B’ C’ D’ E’. What is the y-coordinate if point C’?
Answer:
4
Step-by-step explanation:
When rotating a point 90 degrees counterclockwise about the origin the point A(x,y) becomes A'(-y,x).
Point C has coordinates of (4, 3)
New coordinates will be C'(-3, 4)
So the answer is:
y-coordinate of C' is 4

Write an equation of the line that passes through (2, −2) and is parallel to the line y=3x+9.
Step-by-step explanation:
Parallel lines have the same slope, so we know that our line will have a slope of 3 because y = 3x + 9 has a slope of 3. Now, we can use the point-slope formula of the line to find the equation.
We have y - y₁ = m (x - x₁) (m = 3, x₁ = 2, y₁ = -2)
y- (-2) = 3 (x - 2)
y + 2 = 3x - 6
y = 3x - 8
Hope this helps!
Answer:
y = 3x - 8
Step-by-step explanation:
We know that parallel lines have the same gradient. In this situation we want want to work the equation of the line that is parallel to y = 3x + 9 and passes through ( 2 , - 2 ). We know that equations of lines usually go in the format of y = mx + c
↔ Where 'm' is the gradient / slope
↔ Where 'c' is the y - intercept
Using the information in the first sentence we can set up an equation to find the value of 'c'
⇒ Form the equation
→ y = 3x + c
⇒ Substitute ( 2 , -2 ) into the equation to find the value of c
→ -2 = 6 + c
⇒ Minus 6 from both sides to isolate c
→ -8 = c
⇒ Put the value of c back into y = 3x + c
→ y = 3x - 8
So equation of the line that passes through ( 2, −2 ) and is parallel to the line y = 3x + 9 is y = 3x - 8

[tex]2[/tex]×[tex]10^5[/tex] = [tex]200,000[/tex]
Step-by-step explanation:
When working with scientific notation, you are either given a decimal or whole number. The point of scientific notation is to rewrite a number in a more simplified form.You need to change the number so that there is one number on the left side of the decimal. An exponent is used to describe the change in the number. For example:
0.00003
In order to get one number to the left of the decimal, you need to move the decimal to the right 5 spaces. Since the zeros are to the left of the primary number (3), the exponent will be negative. The exponent itself will be the spaces you moved:
[tex]3[/tex]×[tex]10^{-5}[/tex]
The ten is used because of the decimal places you are moving. When you multiply a number by 10, you add a zero. For example:
[tex]2[/tex]×[tex]10^5[/tex]
Since there is a 10, we will be adding in zeros. The exponent determines how many zeros will be added. Since it is a positive number, the numbers will be to the right of the primary number:
200,000

How much will the guitar be worth in 10 years?
Answer:
$44487
Step-by-step explanation:
If you plug in 10 for t, you are left with the following equation:
[tex]V=12000(1.14)^{10}=12000\cdot 3.7072\approx 44487[/tex]. Hope this helps!
Answer: $44,487
Step-by-step explanation:
To solve this, substitute t (the variable for time in the equation) with 10 to represent the value of the guitar after 10 years.
[tex]V = 12000(1.14)^{10}\\V = 12000*3.7072\\\\V = 44487[/tex]
The guitar will be worth $44,487 in 10 years.
The function g(n) = n2 − 16n + 69 represents a parabola.
Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points)
Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points)
Part C: Determine the axis of symmetry for g(n). (2 points)
Answer:
Step-by-step explanation:
A) y + ? = n^2 - 16n + ? + 69
y + 64 = n^2 -16n + 64 + 69
y + 64 = (n-8)^2 + 69
y = (n-8)^2 + 5
B) vertex is (8,5) because the value of a vertex is always (h,k) from the parent vertex function:
y = a(x-h) + k
it's a minimum only because the (a) value is positive
C) axis of symmetry = 8
