A sine function has an amplitude of 3, a period of pi, and a phase shift of pi/4 What is the y-intercept of the function?
Answers
Answer:
(0, -3)
Step-by-step explanation:
It will help to graph it out.
Also is the phase shift negative or is it just to the right? Im assuming its just right pi over 4
Answer: 0
Step-by-step explanation:
2pi/4 does not equal pi, it equals half of pi. 2pi/2 equals pi. Regardless here's my answer, since it also checks out for a similar function that was confirmed to have a phase shift of pi/2:
The formula for this is asin(bx - c) + d, where
|a| = amplitude
period = 2pi/b
and phase shift = c/b
The amplitude is 3
3sin(bx - c) + d
Phase shift is c/b, in this case, pi/4
3sin(4x - pi) + d
d is vertical shift
(phase shift, c, is also known as horizontal shift)
We don't see any d here so graph on Desmos as follows....
Graph 3sin(4x - pi)
Looks like the y-intercept is 0
Check by substituting 0 for x:
3sin(4x - pi)
3sin(4(0) - pi)
3sin(-pi) = 0
The answer is 0, checks out.

2- Factor the expression
Answer:
They are both correct because you should use both to solve the question. To solve it you will have to find the GCF first and then you find the difference of two squares.

If (-3, y) lies on the graph of y = 3^x, then y =

1/27
-27
Answers
Answer:
1/27
Step-by-step explanation:
If (-3, y) lies on the graph of y = 3^x, then we can find y by filling in the given x and calculating y
They gave us that x is -3 (the first number in an ordered pair is the x).
y = 3^x
y = 3^(-3)
y = 1/(3^3)
**You "fix" a negative exponent by pushing across a fraction bar; that changes the sign of an exponent**
y = 1/27

Answers
Dilation involves changing the size of a square
The vertices of the image are (0,0), (5,10), (15,5) and (10,-5)
How to determine the image of the squareThe vertices of the square are given as:
D(0,0), E(2, 4), F(6,2), and G(4,-2)
The scale factor (k) is given as:
k = 5/2
So, the image of the square is:
[tex]D' = 5/2 * (0,0) = (0,0)[/tex]
[tex]E' = 5/2 * (2, 4) = (5,10)[/tex]
[tex]F' = 5/2 * (6, 2) = (15,5)[/tex]
[tex]G' = 5/2 * (4,-2) = (10,-5)[/tex]
Hence, the vertices of the image are (0,0), (5,10), (15,5) and (10,-5)

How much water should be added to 3 gallons of pure alcohol in order to obtain a solution that is 50% alcohol?
Answers
Answer: 3 gallons of water

3 gallons of alcohol +3 gallons of water = 6 gallons total
alcohol = 3/6 = 50%
let 3+x=amount of alcohol and water in 15% solution.
Let 3 gallons of alcohol=percentage of alcohol*volume of solution

Let x represent the number of houses on each street. Normally, Jake delivers 7x papers, and Ryan delivers 3x papers. On the day when Ryan delivered 45 of Jake's papers, we have ...
(3x +45) > (7x -45)
90 > 4x . . . . . . . . . . . add 45 -3x to both sides
22.5 > x . . . . . . . . . . divide by 4
The number of houses on each street will be an integer, so the maximum number of houses on each street is 22.

Additional comment
If Jake normally delivers more than 45 papers, then we must also have ...
7x > 45
x > 6 3/7
There must be at least 7 houses on each street.
The diagonal of a rectangle is 2under root 13cm.If its length and breadth are in the ratio 3:2, then find its area.
Answers
Answer:
Given :
The diagonal of a rectangle is 2 ✓13 cm.
The length and breadth are in the ratio
3:2.
To find :
The Area of the rectangle.
Solution :
Given that
The ratio of the length and breadth of a rectangle = 3:2
Let they be 3X cm and 2X cm
We know that
The diagonal of a rectangle = √(1²+b³)
units
The diagonal of the rectangle
= √[(3X)³+(2X)³] cm
= √(9x³+4x²) cm
=> √(13X²) cm
=> √13 X cm
According to the given problem
The diagonal of the rectangle = 2√13 cm
=> ✓13 X = 2 √13
=> X = 2√13/√13
=> X = 2 cm
If X = 2 cm then 3X=3(2) = 6 cm
If X = 2 cm then 2X = 2(2)=4 cm
Length = 6 cm
Breadth = 4 cm
We know that
Area of a rectangle = length breadth sq.units
Area of the given rectangle = 6 cm x 4 cm
= 24 cm²

11y+22
Step-by-step explanation:
Answer and Step-by-step explanation:
For this equation, you need to use the distributive property. Before we can solve this, we need to know what the distributive property is. (Important:) The distribute property is where a number is directly outside the parenthesis and is multiplied to each number inside the parenthesis.
With that being said, let's rewrite this expression. Because 11 is outside the parenthesis, multiply it to each of the numbers inside the parenthesis. The numbers 11 x 2 = 22, so:
(y + 2)11 = 11y + 22.
We can remove the parenthesis now that the equation has changed. The reason why the 11 is in front of the y is because it is a coefficient. Coefficients always are written before a variable, which is the y in this case.
So, the answer is 11y + 22.
I hope that this helps.
