Find a function of the form y=Asin(kx)+C or y=Acos(kx)+C whose graph matches the function shown below:
The sinusoidal function that matches the graph given is:
g(x) = 4cos((π/7)x) - 2.
What is the cosine function?The cosine function is defined as follows:
g(x) = acos(bx)+d.
The coefficients have these following roles:
a: amplitude.b: The period is of 2π/b.d: vertical shift.For this problem, we use a cosine function because the function is not zero at the origin, while for the sine it is.
From the graph of this function, the maximum value is of 2, while the minimum value is of -6, hence the amplitude is found as follows:
2a = 8 (difference between these values).
a = 4.
Then:
g(x) = 4cos(bx) + d.
A function with amplitude of 4 should oscillate between -4 and 4, while this one oscillates between -6 and 2, meaning that it was shifted 2 units down, hence d = -2 and:
g(x) = 4cos(bx) - 2.
The period is of 14 units, hence:
2π/b = 14
14b = 2π
b = π/7
Hence the function is:
g(x) = 4cos((π/7)x) - 2.

If Roni and Allie work together to mow the field, what part of the field would Roni mow?
about 0.52 of the field
about 0.64 of the field
about 0.71 of the field
about 0.87 of the field
If Roni has a riding lawn mower and can mow the field in 30 minutes and Allie is pushing a lawn mower and can mow the field in 75 minutes. If Roni and Allie work together to mow the field, about 0.71 of the field will Roni mow.
Time taken by Roni to mow the field = 30 minutes
Time taken by Allie to mow the field = 75 minutes
Work done by the Roni = x/30
Word done by Allie = x/75
Then they are working together
x/30 + x/70 = 1
Solve the equation
[tex]\frac{70x+30x}{2100}=1[/tex]
70x+30x = 2100
100x = 2100
x = 2100/100
x = 21
Then, the work done by Roni = x/30
= 21/30
= 0.70
Hence, if Roni has a riding lawn mower and can mow the field in 30 minutes and Allie is pushing a lawn mower and can mow the field in 75 minutes. If Roni and Allie work together to mow the field, about 0.71 of the field will Roni mow.

The mass of Earth is 5.97 X 10^24 kilograms while the mass of Jupiter is 1.9 x 10^27 kilograms. Approximately how many times greater is the mass of Jupiter compared to Earth? Give your answer in scientific notation.
Provided the figures we have that describe the mass of Earth and the mass of Jupiter, we can conclude that Jupiter is 318 times greater than the mass of Earth.
How do we arrive at the planet with the greater mass?From the figures we have, we can see that the mass of Jupiter is greater than the mass of Earth because it has more zeros.
So, we have to divide the value of the mass of Jupiter by the mass of the earth as follows:
1.9 x 10^27
5.97 X 10^24
=1. 9 ÷ 5.97 × 10^27 - 10^24
= 0.318... ×10³
= 318
Do note that when we have to divide figures that are raised to some figures, the rule will be to subtract the figures as we find in the fact that 27 - 24 is equal to 3. And when we multiply, we arrive at the stated figure.

Using the figure below, Maggie used the definition of vertical angles to help her solve for x. Since vertical angles are congruent, she set the two given expressions equal to each other. After solving for x, her teacher said she got the wrong value for x. Explain where Maggie made her mistake when solving for x.
Maggie's mistake on the solution of the expression for x was when she subtracted 7x to both sides, the result should have been -3x and not 3x.
What is the solution for the equation?The equation is given as follows, as the angles are congruent, that is, they have the same measure:
4x + 2 = 7x - 25.
First, we isolate x on the left side of the equality, subtracting 7x from both sides, hence:
4x + 2 - 7x = 7x - 25 - 7x
Then the correct expression is:
-3x + 2 = -25
Which is where Maggie's mistake happened, on the subtraction of 4x and 7x.
Then, isolating x, we subtract 2 from both sides of the equality, to remove the +2 term on the left side of the equality.
-3x = -27
3x = 27
x = 27/3
x = 9.
The correct solution is x = 9.

How many 1 3/5-inch-thick books can fit on a 1 4/12-inch-long bookshelf?
You can fit ? books on the bookshelf.
Using division we can calculate that 8 books can fit in the 14 inch long bookshelf .
Division is one of the four basic arithmetic operations, or the process by which two numbers are added together to produce a new number. Multiplication, addition, and subtraction make up the remaining operations.
One way to understand the division of two natural numbers is to tally the occasions in which one number is included within another. This number doesn't have to be an integer. For instance, each individual will receive 5 apples if 20 apples are spread evenly among 4 people.Both types of division are applied to various algebraic structures, or means of describing mathematical structure. These contain polynomial rings in a single indeterminate and are known as Euclidean domains. These are the cases where a defined Euclidean division (with remainder) exists.length of book shelf = 14 inch
length of each book = 1 3/5 inch = 1.6 inches
Number of books = 14 ÷ 1.6 = 8.75 books
Hence by division we get that 8 book can be put in the bookshelf.

If x represents the number of drinks purchased and y represents the number of tacos purchased, write and solve a system of inequalities graphically and determine one possible solution.
One possible solution for the system of inequalities that models the situation is: (5,7), when he purchases 5 drinks and 7 tacos.
What is a system of inequalities?A system of inequalities is when multiple variables are related in a context, and then inequalities are built to find the numeric range of values that each variable can assume, according to the constraints in this problem.
For this problem, the variables are defined as follows, as stated in the text:
Variable x: number of drinks purchased.Variable y: number of tacos purchased.Both amounts cannot assume negative values, hence the first constraints are:
x ≥ 0.y ≥ 0.He must buy at least 14 drinks, hence:
x + y ≥ 14.
He must spend at most $40, hence, considering the price of each item, the constraint is given by:
2x + 4y ≤ 40.

Answer: Ray BA and Ray BC
Explanation:
A ray starts at at a fixed point and moves forever in one direction. If we break line AC into two parts BA and BC, then we can form two opposite rays. Another ray points to the right but the letter marked for this isn't clear, so I'm not sure what to write for that ray. Same goes for the dashed ray that points to the left.
BD is a segment because both endpoints are fixed. We don't have either side extending forever in that direction.
