The initial fee charged to customers for using the gym, given the graph showing the charges to customers is $ 20.

To find the initial membership fee, you should look at the y - intercept of the graph.

The y - intercept is the point where the x vale is 0 and this case this point shows the cost when the customers have not worked out in the gym for any hour yet.

This y - intercept is therefore $ 20 as this is the point on the graph where the value of x is 0.

The values of x and y on solving the two simultaneous equations are x = 1 and y = 3.

The simultaneous equations to be solved are 4x + 2y = 10 and x + 2y = 7.

Rearranging the above equations, we have,

- 4x - 2y = - 10 -----(A)

x + 2y = 7  -------(B)

Solving them, we have, -3x = -3

x = 1 ------(C)

Substituting (C) in (B), we have,

1 + 2y = 7

2y = 6

y = 3 ------(D)

Now, let us substitute the x and y values in (A) and (B) and then check.

4x + 2y = 10

4 + 2(3) = 10

A is checked.

x + 2y = 7

1 + 2(3) = 7

Part E: The area that Jordan can walk around is equal to the area of a circle with a radius of 6 feet is 113 square feet.

Part A: Wendell cannot make a triangular garden using pieces A, B, and F because the sum of the lengths of the two shorter sides of a triangle (in this case, pieces A, B, and F) must be greater than the length of the longest side (in this case, piece F, which is 2 feet long) in order for the triangle to be a valid one. Since the sum of the lengths of pieces A and B is 12 feet, which is greater than the length of piece F, it is not possible to make a triangular garden using these pieces.

Part B: Wendell cannot make a triangular garden using pieces D, E, and F because the sum of the lengths of the two shorter sides of a triangle (in this case, pieces D, E, and F) must be greater than the length of the longest side (in this case, piece D, which is 8 feet long) in order for the triangle to be a valid one. Since the sum of the lengths of pieces E and F is 5 feet, which is less than the length of piece D, it is not possible to make a triangular garden using these pieces.

Part C: Wendell can make a rectangular garden with the pieces of wood he has by using pieces A and C or pieces B and D. He cannot use pieces E and F because they are not long enough to make up one of the sides of a rectangle.

Part  D: Wendell can not create two triangular gardens using all six pieces of wood as the sum of the lengths of the two shorter sides of a triangle must be greater than the length of the longest side, and he only have 3 pieces with length greater than 3 feet which is required to create one triangle.

Wendell can create two rectangular gardens using all six pieces of wood by using pieces A and C, and pieces B and D.

Part E: The area that Jordan can walk around is equal to the area of a circle with a radius of 6 feet (since the chain is 12 feet long).

The formula to calculate the area of a circle is πr^2

Both Guillermo's and Cara's solutions are incorrect due to the incorrect substitution of values of a variable to find the dependent one.

Guillermo's solution is incorrect because he did not substitute the value of 'b' from the first equation into the second equation. Instead, he directly added 0.49b to both sides and solved for a, which gives an incorrect result.

Cara's solution is also incorrect because she did not substitute the value of 'a' from the first equation into the second equation. Instead, she used the equation a + b = 7 to solve for the value of b, which gave her an incorrect result.

We can find the correct solution as follows -

The system of equations is,

⇒ a + b = 7   .. (i)

And 1.29a + 0.49b = 6.63 .. (ii)

Now, we will solve the system of equations as follows -

⇒ a + b = 7  

⇒ a = 7 - b .. (i)

And, ⇒ 1.29a + 0.49b = 6.63 .. (ii)

Substitute the value of a from (i) in (ii), we get;

⇒ 1.29a + 0.49b = 6.63

⇒ 1.29(7 - b) + 0.49b = 6.63

⇒ 9.03 - 1.29b + 0.49b = 6.63

⇒ - 0.8b = 6.63 - 9.03

⇒ - 0.8b = - 2.4

⇒ 0.8b = 2.4

⇒ b = 2.4 / 0.8

⇒ b = 3

And, From (i);

⇒ a = 7 - b .. (i)

⇒ a = 7 - 3

⇒ a = 4

FIND THE ERROR In the system a + b = 7 and 1.29a + 0.49b = 6.63, a represents pounds of apples and b represents pounds of bananas a person bought. Guillermo and Cara are finding and interpreting the solution. Is either correct? Explain your reasoning.

a. Guillermo: 1.29a + 0.49b = 6.63 ⇒ 1.29a +0.49(a + 7) = 6.63 ⇒ 1.29a + 0.49a + 3.43 = 6.63 ⇒ 1.78a = 3.2 ⇒ a = 1.8

a + b = 7, so b = 5.2. The solution (1.8, 5.2) means that 1.8 pounds of apples and 5.2 pounds of bananas were bought.

b. Cara: 1.29a + 0.49b = 6.63 ⇒ 1.29(7-b) + 0.49b = 6.63 ⇒ 9.03- 1.29b + 0.49b = 6.63 ⇒ -0.8b = -2.4 ⇒ b=3

From the trigonometric function sec θ = 13/12, two more functions are derived -

Option C: cos θ = 12/13

Option D: tan θ = 5/12

What is trigonometric function?

Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.

The given trigonometric function is -

sec θ = 13/12

Sec function is written as the ratio of hypotenuse to adjacent.

sec θ = 1/cos θ

Cos function is written as the ratio of adjacent to hypotenuse.

cos θ = 12/13

To find the opposite, apply the Pythagoras theorem -

(Opposite)² = (Hypotenuse)² - (Adjacent)²

(Opposite)² = (13)² - (12)²

(Opposite)² = 169 - 144

Opposite = √25

Opposite = 5

Tan function is written as the ratio of opposite to adjacent.

tan θ = 5/12

Therefore, from sec function, cos and tan function are obtained.

An autonomous first order ordinary differential equation is any equation of the form: dy/dt = f(y).

1. Stable: The equilibrium solution y(t) = c is stable if all solutions with initial conditions y0 ‘near’

y = c approach c as t → ∞.

2. Unstable: The equilibrium solution y(t) = c is unstable if all solutions with initial conditions y0 ‘near’ y = c do NOT approach c as t → ∞.

3. Semi-stable: The equilibrium solution y(t) = c is semistable if initial conditions y0 on one side of c lead to solutions y(t) that approach c as t → ∞, while initial conditions y0 on the other side of c do NOT approach c.

Find the equilibrium points for the differential equation (1) and determine whether each is asymptotically stable, semistable, or unstable.

The graph of y0 as a function of y, and the phase line. (It’s important that α is positive – if it were negative, we’d have very different behavior).

We can see that there are two equilibrium solutions: y = 0, which is unstable, and y = 1, which is stable.

Consider 4 sets A, B, C, and D.

Each set has 15 elements.

The pair-wise intersection has 4 elements.

The three-way intersection has 3 elements.

There are 2 elements in the intersection of all sets.

So,

P(A) = P(B) = P(C) = P(D) = 15

P(A ∩ B) = P(A ∩ C) = P(A ∩ D) = P(B ∩ C) = P(B ∩ D) = P(C ∩ D) = 4

Three letters will be selected from five letters. The number of possible selections is 10.

A combination is a method of picking elements from a collection where the order of selection is irrelevant. Assume we have three numbers P, Q, and R. The number of ways we can choose two numbers from each set is determined by combination.

Suppose we want to pick k elements from a set of n elements, then the number ways it can be chosen is:

C(n,k) = n! / k! (n-k)!

Where n! is n factorial.

In this case, there are 5 letters and we want to select three letters. Hence, k = 3, and n = 5.

C(5,3) = 5! / 3! (5-3)!

C(5,3) = 5! / (3! 2!) = 10

The measure of angle B is 20°.

In triangle DEF:

The measure of angle D is 35º and

The measure of angle F is 125

We know that :

Sum of interior angles of triangle is 180°

Now, In ΔABC:

∠A + ∠B + ∠C = 180°

35 +  20 + ∠C = 180°

55° +  ∠C = 180°
