For orders of 50 or fewer sports drinks, the price is $0.80 per drink, plus $10 shipping and handling. When more than 50 sports drinks are ordered, the price is $0.70 per drink, plus $15 shipping and handling. What is the maximum amount of sports drinks you can purchase for $75?
A. 85
B. 81
C. 92
D. 107
Using the equatiοns, we fοund that the maximum amοunt οf spοrts drinks yοu can purchase fοr $75 is 86.
What is meant by an equatiοn?A mathematical equatiοn is a fοrmula that uses the equals symbοl (=) tο cοnnect twο expressiοns and express their equality. The definitiοn οf an equatiοn in algebra is a mathematical statement that prοves twο mathematical expressiοns are equal. LHS = RHS (left-hand side = right-hand side) appears in all mathematical equatiοns. Yοu can sοlve equatiοns tο determine an unknοwn variable's value, which cοrrespοnds tο an unknοwn quantity. It is nοt an equatiοn if there is nο "equal tο" sign in the statement. That shall be taken intο accοunt as an expressiοn.
Let,
the number οf drinks = x
the tοtal cοst οf the x drinks = y
Then we can write equatiοns using the given infοrmatiοn.
When the οrder cοntains 50 οr fewer spοrts drinks, the equatiοn is:
y = 0.8x + 10
When the οrder cοntains mοre than 50 spοrts drinks, the equatiοn is:
y = 0.7x + 15
Since we have tο find the number οf drinks fοr $75, we can write that:
y = 75
Substituting in the equatiοns,
75 = 0.8x +10
65 = 0.8x
x= 81.25 = 81
75 = 0.7x +15
60 = 0.7x
x = 85.7 = 86
Nοw, 86 > 81
Therefοre using the equatiοns, we fοund that the maximum amοunt οf spοrts drinks yοu can purchase fοr $75 is 86.

The graph of polygon FGHI is shown. Graph the image of FGHI after a reflection across the line y=-1. Include the line of reflection. Then write the coordinates of the image.
The coordinates of the reflected polygon F'G'H'I' are as follows:
F'(-2, -1), G'(5, -4), H'(8, -5), and I'(6, -2).
What is the reflection?In mathematics, reflection is defined as the mirror image of a figure crossing a line (drawn or imagined), known as the line of reflection.
The vertices of the polygon FGHI are as follows:
F(2, -1)
G(5, 2)
H(8, 3)
I(6, 0)
To reflect the polygon FGHI across the line y = -1, we need to flip the points over the line.
Now we can reflect each of the points of the polygon across the line y = -1 to get the image:
F(2, -1) stays in the same place because it lies on the line of reflection.
G(5, 2) is reflected to G'(5, -4) by flipping it vertically across the line y = -1.
H(8, 3) is reflected to H'(8, -5), and
I(6, 0) is reflected to I'(6, -2).

2. Determine whether the seriesn=1∑[infinity](−1)n−13n+4ln(5n+2)is absolutely convergent, conditionally convergent or divergent.
The series n=1∑[infinity](−1)n−13n+4ln(5n+2) is conditionally convergent.
To determine the convergence of a series, we can use the Alternating Series Test. This test states that if the absolute value of the terms in the series decrease to zero, then the series is convergent.
First, we need to find the absolute value of the terms in the series:
| (−1)n−13n+4ln(5n+2) | = | 3n+4ln(5n+2) |
Next, we need to determine if the absolute value of the terms decrease to zero. To do this, we can use the Limit Comparison Test. We will compare the series to the series 1/n:
lim n→∞ | 3n+4ln(5n+2) | / (1/n) = lim n→∞ | 3n^2+4nln(5n+2) |
Since the limit of the series is infinity, the series is divergent. However, since the series alternates between positive and negative terms, it is conditionally convergent.
Therefore, the series n=1∑[infinity](−1)n−13n+4ln(5n+2) is conditionally convergent.

If the backpack contains only textbooks and notebooks, which equation can be used to determine t, the weight of the textbooks?
The equation that can be used to determine the weight of the textbooks is t = 0.7(t + 4 + 2) = t
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, the notebooks weigh a total of 4 pounds, and the backpack itself weighs 2 pounds. If the backpack contains only textbooks and notebooks, seventy percent of the total weight is textbooks,
Let the weight of the textbooks= t
The backpack of the book= 2 pounds
The weight notebook in total = 4 pounds
But remember that 70% of total weight is the textbooks.
Therefore, the equation can be computed as
70%(t + 4 + 2) = t
0.7(t + 4 + 2) = t

Given x1 = x2 – x1(x1^2 + x2^2 -1) and x2 = -x1 - x2(x1^2 + x2^2 -1) as state dr do equations. Polar coordinates are r and tetha. Please prove that dr/dt = -r(r^2 -1) and dtetha/dt= -1. Then explain why r=1 is a stable limit cycle.
To solve this problem, we'll start by finding the polar coordinates r and θ in terms of x1 and x2. We have r^2 = x1^2 + x2^2, tan(θ) = x2/x1.
Taking the derivative of x1 with respect to time t, we have: dx1/dt = dx2/dt - 2x1(dx1^2 + x2^2 - 1) - x1^2(2x1dx1 + 2x2dx2)
Similarly, the derivative of x2 with respect to t is: dx2/dt = -dx1/dt -2x2(dx1^2 +x2^2 -1) - x2^2(2x1dx1 + 2x2dx2) Using the chain rule, we can write: dr/dt = (x1dx1 + x2dx2)/r dθ/dt = (1/r^2)(x2dx1 - x1dx2)
Substituting dx1/dt and dx2/dt in these equations and simplifying, we get: dr/dt = -r(r^2 -1) dθ/dt = -1 Now, to prove that r=1 is a stable limit cycle, we can use the method of linearization.
This involves finding the Jacobian matrix at the equilibrium point r=1, θ=0: Jacobian = [[-3 -1], [-1 -3]] Taking the eigenvalues of this matrix, we get -4 and -2.
Since both eigenvalues are negative, we conclude that the equilibrium point corresponds to a stable limit cycle at r=1, θ=0. In summary, we have shown that the differential equations for dr/dt and dθ/dt are -r(r^2 -1) and -1, respectively. We have also demonstrated that r=1 is a stable limit cycle.

find the measures of the numbered angles in rhombus ABCD
Answer:
see explanation
Step-by-step explanation:
the diagonals of a rhombus are perpendicular to each other, then
∠ 1 = 90°
AB and CD are parallel ( opposite sides of a rhombus are parallel )
∠ 2 and 51° are alternate angles and are congruent , then
∠ 2 = 51°
the diagonals bisect the angles , then
∠ 3 = ∠ 2 = 51°
the sum of the 3 angles , in the triangle with ∠ 4 sum to 180°
∠ 1 + ∠ 3 + ∠ 4 = 180°
90° + 51° + ∠ 4 = 180°
141° + ∠ 4 = 180° ( subtract 141° from both sides )
∠ 4 = 39°
then
∠ 1 = 90° , ∠ 2 = 51° , ∠ 3 = 51° , ∠ 4 = 39°
For which value(s) ofcdoes the equationx+4−c=0has a solution. (A)c=−4(B)c=0(C)0
For none of the option the linear equation x+4=c have solution.
The equation x + 4 - c = 0 can be rearranged to isolate the variable c on one side of the equation. This gives us:
c = x + 4
Now, we can see that the value of c depends on the value of x. In other words, there are infinitely many values of c that make the equation true, as long as they are equal to x + 4.
So the answer to the question is that there are infinitely many values of c that make the equation x + 4 - c = 0 true. None of the given options (A) c = -4, (B) c = 0, or (C) 0 are correct.

what is angle ?An angle is a figure created in geometry by two rays or line segments that meet at the vertex of the angle. The edges of the angle are the rays or line segments. Angles are used to describe the amount of rotation or turn between two lines or objects. For instance, a 90-degree angle is equivalent to a quarter turn, while a 180-degree angle is equivalent to a half turn or a straight line. A full turn plus a smaller angle is equivalent to an angle that is larger than 180 degrees but less than 360 degrees.
given
In degrees, express each radian number.
• 3 radians equals 60 degrees (multiply the radian measurement by 180/ to transform radians to degrees).
• 225 degrees = 5/4 radians
Use radians to determine each degree.
• 30° Equals /6 radians (multiply the degree measurement by /180 to convert degrees to radians)
• 120° equals 2.3 radians
Circle the larger angle between each set of measurements.
• Radians or degrees: 200 degrees (to measure, 180 degrees are equal to one radian).

What is the set of x-intercepts of this graphed function?
-3, -1, 3
Step-by-step explanation:X-intercepts are also known as the roots or zeros of a function.
Finding Intercepts From Graphs
In the problem, we are given a basic polynomial graph. The x-intercepts are where the graphs intersect with the x-axis. Remember that the x-axis is the horizontal axis. Finding x-intercepts when given a graph is as simple as just looking to see where the line crosses over. We can see that the graph crosses the axis in three points. The x-intercepts are x = -3, -1, and 3.
Finding Intercepts From Equations
In this question, we are not given an equation, but if we were there is another possible way to solve it. The x-intercepts occur when y = 0. So, to find x-intercepts from an equation, all you need to do is plug 0 in for y and solve.
The scale factor of two similar hexagons is 3:7.
The area of the smaller hexagon is 18 m2.
What is the volume of the larger hexagon?
Question 7 options:
5832 m2
36 m2
42 m2
324 m2
98 m2
Since the two hexagons are similar, their corresponding sides are in the same ratio as the scale factor.
Let x be the length of a side of the smaller hexagon, then the corresponding length of a side of the larger hexagon can be expressed as (3/7)x.
The area of a hexagon can be calculated using the formula: A = (3√3/2)s², where s is the length of a side.
Since the area of the smaller hexagon is 18 m², we can solve for x as follows:
18 = (3√3/2)x²
x² = 12/√3
x = 2√3
Now we can calculate the area of the larger hexagon:
Area of the larger hexagon = (3√3/2)(3/7x)² = (3√3/2)(3/7(2√3))² = 54/49 m²
Finally, we can calculate the volume of the larger hexagon, assuming it is a regular hexagonal prism:
Volume of the larger hexagon = Area of hexagon x Height
The height of the hexagonal prism is the same as the length of the side of the larger hexagon, which is (3/7)x:
Volume of the larger hexagon = (54/49) x (3/7)x = 54/343 x² ≈ 0.212 x²
Substituting the value of x, we get:
Volume of the larger hexagon ≈ 0.212 x (2√3)² = 1.272 m³
Therefore, the volume of the larger hexagon is approximately 1.272 m³.
Well, I'm not sure if it's correct but I got 42.
I got this by doing something along the lines of:
1) 18/x = 3/7
2) Cross multiply
3) 3x = 126
4) Divide both sides by 3
5) x = 42

Report answers accurate to 4 decimal places.
The maximum value of the function is 6.9159 and the minimum value is -6.9159, accurate to 4 decimal places. The answers should be provided as a list separated by commas, so the final answer is:
max = 6.9159, min = -6.9159
The first step in solving 5sin(x)−2cos(x)=3 is to rearrange the equation to isolate the sin(x) term. We can do this by adding 2cos(x) to both sides of the equation:
5sin(x) = 3 + 2cos(x)
Next, we can divide both sides of the equation by 5 to isolate the sin(x) term:
sin(x) = (3 + 2cos(x))/5
Now, we can use the Pythagorean identity sin^2(x) + cos^2(x) = 1 to substitute for cos(x) and solve for sin(x):
sin^2(x) = (3 + 2√(1 - sin^2(x)))/5
Multiplying both sides of the equation by 5 and rearranging gives us:
5sin^2(x) - 2√(1 - sin^2(x)) - 3 = 0
We can use the quadratic formula to solve for sin(x):
sin(x) = (-(-2) ± √((-2)^2 - 4(5)(-3)))/(2(5))
Simplifying gives us:
sin(x) = (2 ± √(28))/10
Using a calculator, we can find the first 2 positive solutions for x:
x = sin^-1((2 + √(28))/10) ≈ 0.72, 2.42
Therefore, the first 2 positive solutions for x are 0.72 and 2.42, accurate to at least 2 decimal places.
To find the maximum and minimum values of f(x)=5.7sin(x)−3.9cos(x), we can use the formula:
max = √(a^2 + b^2)
where a and b are the coefficients of the sin(x) and cos(x) terms, respectively. Substituting in the values for a and b gives us:
max = √((5.7)^2 + (-3.9)^2) ≈ 6.9159
The minimum value of the function is the negative of the maximum value:
min = -6.9159
Therefore, the maximum value of the function is 6.9159 and the minimum value is -6.9159, accurate to 4 decimal places. The answers should be provided as a list separated by commas, so the final answer is:
max = 6.9159, min = -6.9159

Gina wants to take dance classes. She compares two dance studios to determine which has the best deal for her. Dance World charges a rate for each class. Toe Tappers charges a rate for each class plus a one-time registration fee. The system of equations shown models the total costs for taking x classes at each.
The system of equations shown models the total costs for taking 10 classes at each.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that Toe Tappers charges a rate for each class plus a one-time registration fee.
Dance World, y = 15x
Toe Tappers, y = 25 + 12.5x
Where x = number of classes
Now Equate the total cost at both dance studios;
15x = 25 + 12.5x
Collect like terms;
15x - 12.5x = 25
2.5x = 25
Divide both sides by 2.5;
2.5x / 2.5 = 25 / 2.5
x = 10 classes
Thus, x = number of classes = 10
