Hi:) why is the gradient of vertical lines undefined?

Mademuasel [1]

Answer:

The gradient of a line is given by $\frac{y1 - y2}{x1 - x2}$ .

Any 2 points of a vertical line would have the same x-coordinate. Thus when you simplify the denominator, you would end up with a zero. If you enter that into your calculator, no matter what you numerator is, you would get a Math error. This is because you cannot possibly divide a number by zero. Thus, the gradient is undefined.

Assume a program has the following variable defenition: int a, b =2; float c = 4.2; and the following statement: a = b * c; What

Vladimir [108]

Answer:

The correct option is B.

Step-by-step explanation:

In a program the variables are defined as

int a, b =2;

float c = 4.2;

The given statement is

a = b * c

a = 2 * 4.2

a = 8.4

It is given that variable a is an integer. So, only integer value can be stored in a.

a ≈ 8

It means 8 will be stored in a. Therefore the correct option is B.

Let A fa, b,c. B [a, b, d), and C tb, d,e. Find the union of A and B, and then the union of this with C. Also, find the union of

Andre45 [30]

Answer: A ∪ B = {a, b, c, d}

(A ∪ B) ∪ C = = {a, b, c, d, e}

B ∪ C = = {a, b, d, e}

(B ∪ C) ∪ A = = {a, b, c, d, e}

Step-by-step explanation:

A = {a, b, c} B = {a, b, d} C = {b, d, e}

Union means "to join" so combine the sets to form a union.

A ∪ B = {A & B}

= {a, b, c & a, b, d}

= {a, b, c, d} because we do not need to list a & b twice

(A ∪ B) ∪ C = {(A ∪ B) & C)

= {a, b, c, d & b, d, e}

= {a, b, c, d, e} because we do not need to list b & d twice

B ∪ C = {A & B}

= {a, b, d & b, d, e}

= {a, b, d, e} because we do not need to list b & d twice

(B ∪ C) ∪ A = {(B ∪ C) & A)

= {a, b, d, e & a, b, c}

= {a, b, c, d, e} because we do not need to list a & b twice
