SUPER URGENT: Complete the general form of the equation of a sinusoidal function having an amplitude of 6, a period of 2pi/3, and a phase shift to the left 1 unit.
y =
Answers
Answer:
A general sinusoidal equation is:
y = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency
p is the phase shift
M is the midline.
Now, we know that:
Amplitude must be 6, so A = 6
period is 2*pi/3
Remember that the frequency is the inverse of the period, then:
f = 1/T
f = 1/(2*pi/3) = 3/(2*pi)
And the angular frequency is 2*pi times the normal frequency, then:
w = 2*pi*f = 2*pi*(3/2*pi) = 3
w = 3
Here we not have information about the midline, so M = 0.
And we know that the phase shift is one unit to the left.
Remember horizontal translations:
for a function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
if N > 0, then the translation is to the left
if N < 0 , then the translation is to the right,
Here we know that the phase shift is to the left, so p must be positive, and we know that the shift is 1 unit to the left, then:
p = +1
Replacing these in the equation we get:
y = 6*sin(3*x + 1) + 0
y = 6*sin(3*x + 1)

Answer:
[tex]y=3x-7[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the points given are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Points (3,2) and (6,11)
[tex]=\frac{11-2}{6-3}\\=\frac{9}{3}\\= 3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=3x+b[/tex]
Plug in one of the given points and solve for b
[tex]2=3(3)+b\\2=9+b[/tex]
Subtract 9 from both sides
[tex]2-9=9+b-9\\-7=b[/tex]
Therefore, the y-intercept of the line is -7. Plug this back into [tex]y=3x+b[/tex]:
[tex]y=3x-7[/tex]

Step-by-step explanation:

2. A parallelogram is a four-sided figure with two pairs of parallel sides. This fits exactly with the image that is shown. But let's check the other answers first.
3. While rectangles also have 2 pairs of parallel sides, rectangles have 4 equal angles (90 degrees angles) just like squares do, it can't be a rectangle.
4. A rhombus has four equal sides, meaning this figure can't be a rohmbus.
5. It can't be a trapezoid since trapezoids only have one pair of parallel sides. This figure has 2 pairs of parallel sides.
6. Only B. Parallelogram could possibly be right. Therefore, the answer to this question is that B. Parallelogram is the type of polygon that this figure is.

The length is 5
Step-by-step explanation:
Let the length be x
Width = ( X - 2)
Area = 15
area = length * width
15 = x(x -2)
15 = x² - 2x
x² - 2x - 15 = 0
(x² + 3x) - (5x - 15) = 0
x(x + 3) - 5(x + 15) = 0
x - 5 = 0 or x + 15 = 0
x =5 or x = -15

Mrs. Kelly's brother is 15 year younger than her. Their combined ages add up to 62 years. What is Mrs. Kelly's age
Answers
Answer:
38.5 years old
Step-by-step explanation:
Let us represent Mrs.Kelly's age with the parameter (k). It is given that her brother is (15) years younger than her, thus his age is (k - 15). It is given that the sum of their ages is (62). Therefore one can form an equation with the given information and solve for the unknown.
(Mrs.Kelly's age) + (Brother) = (62)
Substitute,
(k) + (k - 15) = 62
Simplify,
k + k - 15 = 62
2k - 15 = 62
Inverse operations,
2k - 15 = 62
2k = 77
k = 38.5

(2x-4)^12= 16777216
Take the 1/12 exponent for both sides
that will remove the ^12 exponent from the left side and will take the 12th root for the right.

Out of the people who have already taken their seats at a seminar, 2 people have black hair while 2 people do not. Considering this data, how many of the next 16 people to take their seats should you expect to be black-haired?
Answers
Answer:8
Step-by-step explanation:
We can expect 8 of the next 16 people to have black hair, based on the given information.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Since 2 out of the total number of people who have already taken their seats at the seminar have black hair
we can assume that the probability of a person having black hair is 2 out of the total number of people who have taken their seats.
The probability of a person having black hair can be expressed as:
P(black hair) = 2/(2+2) = 1/2
This means that out of the total number of people who have already taken their seats, half of them have black hair.
If we assume that the next 16 people to take their seats are chosen randomly and independently from the population,
we can use the expected value formula to calculate the number of people with black hair we would expect among those 16 people:
Expected value = total number of people x probability of having black hair
Expected value = 16 x (1/2)
Expected value = 8
Therefore, we can expect 8 of the next 16 people to have black hair, based on the given information.

find the value of x and y, (x+y, 2x-y)= (13, 2)
Answers
Answer:
Step-by-step explanation:
comparing corresponding elements
x + y = 13
2x - y = 2
Now use substitution method.
x + y = 13
x = 13 - y equation(i)
substitute the value of x
2x - y = 2
2(13 - y) - y = 2
26 - 2y - y = 2
-3y = 2 - 26
y = -24/-3
y = 8
substitute the value of y in eqaution(i)
x = 13 - y
x = 13 - 8
x = 5
therefore , x = 5 and y = 8
To check :
x + y = 13
when we add x and y then must come 13
5 + 8 = 13
13 = 13
2x - y = 13
substitute the value of x and y . REsult must come 2
2*5 - 8 = 2
10 - 8 = 2
2 = 2
10 - 8 = 2
Answer:
x = 5, y = 8
Step-by-step explanation:
Another way to write (x+y, 2x-y)= (13, 2) is
x + y = 13 -- (1)
2x - y = 2 -- (2)
using the elimilation method,
Rewriting (1), y = 13 - x --(1)'
Replacing (1)' into (2),
2x - ( 13 - x) = 2
2x - 13 + x = 2
3x = 15
x = 5 -- (3)
Replacing (3) into (1),
5 + y = 13
y = 8 -- (4)
Accorindg to (3) and (4),
x = 5, y = 8
