Step-by-step explanation:

The red graph intersects the y-axis at (0, 1).  This is the "y-intercept."

In this proof, we first assume that A ⊆ B and take an arbitrary element x of B^c. Then, we assume for the sake of contradiction that x is also an element of A.

Using the fact that A ⊆ B, we show that x must also be an element of B, which contradicts our assumption that x is in B^c. This contradiction allows us to conclude that our assumption that x is in A must be false, and therefore x is in A^c. Since x was arbitrary, we have shown that for any element of B^c, it must also be in A^c. Therefore, B^c ⊆ A^c.

To prove the statement "If A ⊆ B, then B^c ⊆ A^c," we can use the following proof skeleton:

Proof:
1. Let x be an arbitrary element of B^c.
2. Assume for the sake of contradiction that x is an element of A.
3. Since A ⊆ B, we know that x is also an element of B.
4. But this contradicts our assumption that x is an element of B^c.
5. Therefore, our assumption that x is an element of A must be false.
6. Thus, x is an element of A^c.
7. Since x was arbitrary, we have shown that for any x in B^c, x is in A^c.
8. Therefore, B^c ⊆ A^c, as required.

Answer: 460 students

Step-by-step explanation:

Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.

Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:

= 50% of x = 230

0.5 × x = 230

0.5x = 230

x = 230/0.5

x = 460

Therefore, 460 students attend the school.

The exponential function in the form of an equation will be equal to \(y = 7(5.6)^x\).

Exponents are used in exponential functions, as the name implies. But take note that an exponent does not have a variable as the exponents and a fixed as the base.

As per the given information in the question,

The exponential form of the equation is,

\(y = ab^x\)

Where:

Now, the interest rate in decimal notation is determined by dividing the percentage by 100:

Now, we are asked to determine the time required for the quantity to double. Therefore, we need to determine "t" when:

Substituting in the formula we get:

Now, we can cancel out the "P":

\(\tt Solve~for~y:\)

To solve for y, we have to move all of the terms that do not equal to y on one side, and let y be on the other side alone. Do this by subtracting 3x on both sides to cancel it out from the left side and bring it to the right.

\(\tt 3x-3x+y=-5-3x\\y=-5-3x\\y=-3x-5\)

\(\tt Solve~for~x:\)

To solve for x, we will do the same thing we did to solve for y: move all the terms that do not equal to x to one side, and leave x on another side of the equation. We can do this by first subtracting y from both sides.

\(\tt3x+y-y=-5-y\\3x=-y-5\)

Then, we divide all terms by 3 to isolate the x.

Dillon recommends that the amount of time college students spend studying each week should be about the amount twice the time spent in class.

A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality represented by k, according to the rule presented as follows:

y = kx

For this problem, the variables are presented as follows:

From the table, the constant is calculated as follows:

k = 24/12 = 18/9 = 12/6 = 2.

Meaning that the amount of study should be twice the time spent in class.

Step-by-step explanation:

1. Two lines that do not lie in the same plane and are parallel:

- Line 1: x = 2y + 3z

- Line 2: x = 2y + 3z + 5

In this case, both lines have the same direction vector, which is [2, 1, 0], but they do not lie in the same plane.

2. Two planes that have no point in common and are skew lines:

- Plane 1: x + 2y - z = 4

- Plane 2: 2x - 3y + z = 6

These two planes are skew because they do not intersect and have no common points.

3. Two lines that are in the same plane and have no points in common are not called parallel planes. In this case, they are referred to as coincident lines.

Parallel planes are planes that do not intersect and are always separated by a constant distance.

If you are looking for an example of parallel planes, here's one:

- Plane 1: x + 2y - z = 4

- Plane 2: x + 2y - z + 5 = 0

Both planes have the same normal vector [1, 2, -1], and they are parallel to each other.

A scientist adds iodine as an indicator to an unknown substance. This indicator will reveal the presence of starch about the substance.What is an indicator?An indicator is a substance that helps in identifying the presence or absence of another substance or property. Indicators can be both physical and chemical.

The iodine is used as an indicator in this scenario. It's mainly used to indicate the presence of starch in any unknown substance. It's because iodine interacts with starch to produce a bluish-black colour.How can iodine detect starch?Iodine is a dark-colored solution, usually brown, but it turns blue-black when it encounters starch molecules. It's because the iodine molecule slips between the glucose monomers in the starch molecule, forming a helix.The helix that forms between the glucose and iodine molecules causes the iodine to appear blue-black. Therefore, the presence of iodine as an indicator will reveal the presence of starch about the substance.

the base of the triangular window is 24 feet and the height is 10 feet.

Let's denote the height of the triangular window as h feet. According to the given information, the area of the window is 120 square feet.

The formula to calculate the area of a triangle is:

Area = (1/2) × base × height

In this case, we can write the equation as:

120 = (1/2) × base × h

Now, we are also given that the base of the window is 4 feet more than twice the height. So we can express the base as:

base = 2h + 4

Substituting this expression for the base into the area equation, we have:

120 = (1/2) × (2h + 4) × h

Now we can solve this equation for the height.

Multiplying both sides of the equation by 2 to remove the fraction:

240 = (2h + 4) × h

Expanding the right-hand side:

240 = 2h² + 4h

Rearranging the equation and setting it equal to zero:

2h² + 4h - 240 = 0

Now we can solve this quadratic equation. Factoring out a 2:

2(h² + 2h - 120) = 0

Factoring the quadratic expression inside the parentheses:

2(h + 12)(h - 10) = 0

Setting each factor equal to zero:

h + 12 = 0   or   h - 10 = 0

Solving these equations, we get:

h = -12   or   h = 10

Since height cannot be negative in this context, we discard the negative value. Therefore, the height of the triangular window is h = 10 feet.

Substituting the height value back into the expression for the base:

base = 2h + 4

    = 2(10) + 4

    = 20 + 4

    = 24

Therefore, the base of the triangular window is 24 feet and the height is 10 feet.
