1-6-√21, −6+ √21}
(6-√51, 6+ √51)
16-√21, 6+ √21}
Answers
Answer
B
Step-by-step explanation:
The solution to the equation by completing the square is (6 - √21, 6 + √21)
How to complete the square?The equation is given as:
x²= 12x-15
Rewrite as:
x² -12x = -15
Take the coefficient of x
k = -12
Divide by 2
k/2 = -6
Square both sides
k/4 = 36
Add 36 to both sides of x² -12x = -15
x² -12x + 36 = -15 + 36
Evaluate the sum
x² -12x + 36 = 21
Express the equation as a perfect square
(x - 6)² = 21
Take the square root of both sides
x - 6 = ±√21
Add 6 to both sides
x = 6 ± √21
Split
x = (6 - √21, 6 + √21)
Hence, the solution to the equation by completing the square is (6 - √21, 6 + √21)

Write the equation of the graph of y = cos(x) was shifted downwards by 3 units, shrink horizontally by a fourth of a unit, inverted horizontally and shifted 60° to the left. if it has an amplitude of 5 units.
Answers
The equation of the transformed function is y = 5cos(x/4 + 60) - 3
How to determine the equation?The equation of the graph is given as:
y = cos(x)
The rule of downward shift is:
(x, y) ⇒ (x, y - h)
So, the function when shifted downwards by 3 units is
y = cos(x) - 3
The rule of horizontal shrink is:
(x, y) ⇒ (x/k, y)
So, the function when shrink horizontally by a fourth unit is:
y = cos(x/4) - 3
The rule of left shift is:
(x, y) ⇒ (x +h, y)
So, the function when shifted left by 60 units is
y = cos(x/4 + 60) - 3
The amplitude is given as:
A= 5
So, we have:
y = 5cos(x/4 + 60) - 3
Hence, the equation of the transformed function is y = 5cos(x/4 + 60) - 3

let A={1,2,3,4,5} and B={4,5,6} Let R is relation from A to B defined by R={(a,b):a+b ⊆ B} Then Find 1. R 2. Domain (R) 3. Range (R) 4.Inverse of R
Answers
1. Disregard my comment. Since R is said to be a relation from A to B, we take both a ∈ A and b ∈ A. Then the set R is the pairs (a, b) whose entries' sum belongs to B.
We have
• 4 = 1 + 3 = 2 + 2 = 3 + 1, so R contains (1, 3), (2, 2), and (3, 1)
• 5 = 1 + 4 = 2 + 3 = 3 + 2 = 4 + 1, so R contains (1, 4), (2, 3), (3, 2), and (4, 1)
• 6 = 1 + 5 = 2 + 4 = … = 5 + 1, so R contains (1, 5), (2, 4), …, (5, 1)
Then
R = {(1, 3), (1, 4), (1, 5), (2, 2), (2, 3), (2, 4),
… (3, 1), (3, 2), (3, 3), (4, 1), (4, 2), (5, 1)}
2. The domain of R is the set of all values a in the pairs (a, b) belonging to R :
dom(R) = {1, 2, 3, 4, 5}
3. The range of R is the set of all values b in those same pairs:
range(R) = {1, 2, 3, 4, 5}
4. The inverse of R is the set with the same elements as R, but the entries are swapped:
inv(R) = {(3, 1), (4, 1), (5, 1), (2, 2), (3, 2), (4, 2),
… (1, 3), (3, 2), (3, 3), (1, 4), (2, 4), (1, 5)}
In this case, we have R = inv(R).

cos 32.4 = x / 5.5
5.5 cos 32.4 =x
We will consider the third side 2x.
So, 2( 5.5 cos 32.4) is the third side

Step-by-step explanation:
if each pie has 8 slices, then you must do 8+8+8... and so on until u reach 38. However you wont get exactly 38 because 8 doesn't add up evenly into 38. You can find the exact number by divding the amount of people, 38, by the number of slices per pie, 8. The answer will be 4.75 but you can not buy a fraction of a pie so you must round up to 5 whole pies. There will be extra left over in the end, but you cant round down because 4 pies would not be enough, so you must buy 5.
