Remember that the domain is all possible x values of a function. In the case of sine and cosine functions, they go up and down (like waves), but go on forever. Therefore, the domain is all real numbers.
Correct Answer: B, All Real Numbers
Hope this helps!
Explanation:
For the equations y = sin(x) and y = cos(x), we can replace x with any real number we want. The output y value will be between -1 and 1, inclusive of both endpoints.
The graph for each function shows a bouncing wave stretching forever to the left and right. This visually confirms the domain.

Which solution correctly solves the problem 5x - 16 = 79?
Answers
Answer and Step-by-step explanation:
Alright, so we have the problem 5x-16=79. First, we need to add 16 to both sides of the equation to cancel out the 16 like this:
5x - 16 = 79
+ 16 + 16
5x = 95
Now we need to divide the 5 into the 5x to cancel out the 5. This will leave us with the variable left over like this:
x = 95
5
Five can be divided into 95, so 95 divided by 5 = 19. So the answer is:
x = 19
I hope this helps.
The solution to the given equation is 19.
The given equation is 5x-16=79.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 5x=79+16
5x=95
x=95/5
x=19
Therefore, the solution to the given equation is 19.

A landscaper wants to increase the size of one of his square gardens. The garden measures 8 feet on each side. The landscaper
plans to increase each side of the garden to be 175% of its current measure.
How many square feet larger is the area of the new garden than the area of the current garden?
A. 260ft
B.160ft
C.132ft
D.48
Answers
Answer:
its c
Step-by-step explanation:
The area of the new garden will be 132ft longer than that of the current garden
Area of the squareThe formula for calculating the area of a square is expressed as:
A = L²
If the garden measures 8 feet on each side, then;
A = 8²
A = 64ft²
If the side length is increased by 175%, hence new length will be;
l = 8 + (1.75*8)
A = 14 * 14ft
A = 196 ft²
Difference = 196 - 64
Difference = 132ft
Hence the area of the new garden will be 132ft longer than that of the current garden

What percent of 56 is 21?
A: 3/8%
B: 3 3/4%
C: 37 1/2%
D:375%
Answers
Answer:
[tex]37\frac{1}{2}[/tex]
Step-by-step explanation:
let x be the percent
Now we have
x% of 56=21
x/100=21/56
x=100x21/56
x=[tex]31\frac{1}{2}[/tex]%
The percent of 56 that is equal to 21 is 37 1/2% by setting up a proportion and solving the equation. This means that 37 1/2% of 56 is equal to 21.
To find the percentage, we can set up a proportion. Let x represent the unknown percentage:
x/100 = 21/56
To solve for x, cross-multiply:
56x = 100 * 21
56x = 2100
Divide both sides of the equation by 56 to isolate x:
x = 2100/56
Simplifying the fraction, we get:
x = 37 1/2%
Therefore, the answer is option C: 37 1/2%.
To find the percentage of 56 that is equal to 21, we can set up a proportion between the unknown percentage and the given values. The proportion is x/100 = 21/56. Cross-multiplying and solving the equation yields x = 37 1/2%. This means that 37 1/2% of 56 is equal to 21.

Answers
The number of listeners is given from the total number of listeners and
the ratio of the listeners between the two stations.
Required:
The FM sister station has 21,000 listenersHow is the given ratio of listeners used to find the number of listeners?Given:
The daily listening audience of the AM station = 4 × The audience of the FM sister station
The number of people that listen to the two stations = 105,000
Required:
The number of listeners of the FM station
Solution:
The ratio of the listeners is 1:4
Let x represent the number of listeners of the FM sister station, we have;
The number of listeners of AM radio station = 4·x
Which gives;
4·x + x = 105,000
5·x = 105,000

Let n be the middle number of three consecutive Integers. Write an expression for the sum of these Integers.
Answers
Consecutive integers are those that occur one after the other. Let's use 2, 3, 4 as an example.
The middle number is 3 (n). To get to 2 from 3, we need to subtract 1 (n - 1). To get to 4 from 3, we need to add 1 (n + 1).
Now that we understand how to get to each number from the middle number, we can create our expression.
(n - 1) + n + (n + 1)
(n + n + n) + (1 - 1)
3n + 0
Answer: 3n
Hope this helps!
Answer:
3nStep-by-step explanation:
We know that:
n is the middle number of the three consecutive numbers.The three consecutive numbers can be represented as n - 1, n, n + 1.Solution:
=> x + n + y (n = middle number)=> n - 1 + n + n + 1 (n = middle number)=> 3nHence, the sum of the three consecutive numbers is 3n.
You went shopping last weekend and bought a new shirt. The shirt had an original price of $39.00 but it was on sale for 35% off the regular price. The sales tax is 6%. What is the total price you will pay for the shirt?
Answers
Answer:
$26.87
Step-by-step explanation:
if the shirt was 35% off, then you paid 65% of the cost
that value can be found by:
39 x .65 = 25.35 (this is the amount paid for the shirt)
sales tax of 6% on 25.35 is:
.06 x 25.35 which equals 1.52
25.35 + 1.52 = 26.87

exponent 2 and the radical cancel each other:
1 + 1 - x = 2x + 4
2 - x = 2x + 4
like terms on each side ( when you move one term tp the other side, it changes its sign ):
2-x = 2x+4
2-4 = +x +2x
-2 = 3x
now to keep the x alone, divide both sides by 3:
-2/3 = 3x/3
-2/3= x
