Answer: x = 1, -13

Step-by-step explanation:

      We will solve this by completing the square, as asked in the instructions. If we do this correctly, we will end up with a perfect square that will allow us to solve more easily.

Given:

      x² + 12x = 13

Set the equation equal to 0 by subtracting both sides of the equation by 13:

      x² + 12x - 13 = 0

Group the first two terms:

      (x² + 12x) - 13 = 0

Add and subtract [tex]\frac{b}{2} ^2[/tex] to the grouped terms:

      (x² + 12x + 36 - 36) - 13 = 0

Regroup the terms, move the negative out and simplify:

      (x² + 12x + 36) - 49 = 0

Factor the grouped terms (6 is our perfect square here):

      (x + 6)(x + 6) - 49 = 0

Add 49 to both sides of the equation and simplify the factors:

      (x + 6)² = 49

Square root both sides of the equation:

      x + 6 = 7           x + 6 = -7

Subtract 6 from both sides of each equation:

    x = 1           x - 13

The horizontal axis is the real axis and the vertical axis is the imaginary axis. We find the real and complex components in terms of r

and θ

where r

is the length of the vector and θ

is the angle made with the real axis.

From Pythagorean Theorem :

r2=a2+b2

By using the basic trigonometric ratios :

cosθ=ar

and sinθ=br

.

Multiplying each side by r

:

rcosθ=a  and  rsinθ=b

The rectangular form of a complex number is given by

z=a+bi

.

Substitute the values of a

and b

.

z=a+bi    =rcosθ+(rsinθ)i    =r(cosθ+isinθ)

In the case of a complex number, r

represents the absolute value or modulus and the angle θ

is called the argument of the complex number.

This can be summarized as follows:

The polar form of a complex number z=a+bi

is z=r(cosθ+isinθ)

, where r=|z|=a2+b2−−−−−−√

, a=rcosθ  and  b=rsinθ

, and θ=tan−1(ba)

for a>0

and θ=tan−1(ba)+π

or θ=tan−1(ba)+180°

for a<0

.

Example:

Express the complex number in polar form.

5+2i

The polar form of a complex number z=a+bi

is z=r(cosθ+isinθ)

.

So, first find the absolute value of r

.

r=|z|=a2+b2−−−−−−√    =52+22−−−−−−√    =25+4−−−−−√    =29−−√     ≈5.39

Now find the argument θ

.

Since a>0

, use the formula θ=tan−1(ba)

.

θ=tan−1(25)    ≈0.38

Note that here θ

is measured in radians.

Therefore, the polar form of 5+2i

is about 5.39(cos(0.38)+isin(0.38))

.

Step-by-step explanation:

Solving by factoring is a strategy used to find the solutions or roots of a quadratic equation in the form of ax^2 + bx + c = 0. The goal of factoring is to rewrite the equation in the form of (x-r)(x-s) = 0, where r and s are the solutions or roots of the equation. Once the equation is in this form, we can use the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero.

Here is an example to illustrate the process:

Example: Solve the equation x^2 + 5x - 14 = 0 using factoring.

Step 1: Rewrite the equation in standard form (ax^2 + bx + c = 0). In this case, a = 1, b = 5, and c = -14.

Step 2: Factor the equation by looking for two numbers that multiply to give c and add to give b. In this case, the two numbers are -7 and 2, since (-7)(2) = -14 and -7 + 2 = -5.

Step 3: Rewrite the equation as (x + 7)(x - 2) = 0.

Step 4: Use the zero product property to set each factor equal to zero and solve for x.

x + 7 = 0 or x - 2 = 0

x = -7 or x = 2

So the solutions or roots of the equation are x = -7 and x = 2.

It's important to note that not all quadratic equations can be factored, and in such cases, other methods like completing the square or using the quadratic formula should be used.

It's also important to understand that when factoring, it's important to make sure that you have correctly factored the equation, if not the solution will be wrong.

Answer:

( - inf, 5) (9, inf )

Step-by-step explanation:

The arrow(s) at the end of the line indicate that the highlighted green line does not stop at a specific number, hence the use of infinity signs (inf). If the arrow is going to the left on a line, then the value would be negative infinity. If it is going to the right, then it would be positive.

As for the space in between the green arrows pointing separate ways, there are two points, one which is positioned at the number 5 and the other at the number 9. Because there are two separate points which are both solid green, the use of parentheses is needed. The final answer is, as mentioned, ( - inf, 5) (9, inf ).

This is a mathematical problem that can be solved using algebra. Let P be the original amount borrowed, and R be the interest rate as a decimal (for example, 5% would be represented as 0.05).

We know that at the end of 25 years, the amount borrowed has trebled, so the total amount is 3P. We also know that the interest is calculated using simple interest, which is calculated as P x R x T, where T is the number of years.

So we can set up the equation:

3P = P + P x R x 25

To find R, we can solve for R by dividing both sides of the equation by P:

3 = 1 + 25R

Then by subtracting one from both sides we have :

2 = 25R

Then by dividing both sides by 25 we can find the rate as :

R = 2/25

Finally, to find the interest rate as a percentage, we multiply R by 100:

rate = 2/25 x 100 = 8%

So the interest rate is 8% per annum

The alternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent.

State Alternate angle theorem?

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs. These angles are called alternate interior angles.

When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

Angles that are on opposite sides of the transversal are called alternate angles. All angles that are either exterior angles, interior angles, alternate angles or corresponding angles are all congruent.

In the above-given figure, you can see, two parallel lines intersected by a transversal AB.

So according to the alternate angle theorem,

m∠3 = m∠6

Now moving on to the students' explanations, both logics are correct.

The Angle Bisector Theorem states that in a triangle, if a line bisects one angle of a triangle and is also a median to the side opposite of that angle, then the ratio of the length of the median to the length of the side opposite the angle bisected is equal to the ratio of the length of the other two medians.

Therefore, if the angle bisector divides the opposite side into segments 6 cm and 9 cm long, the ratio of the length of the median to the length of the side opposite the angle bisected is 6/9.

Let x be the length of the third side of the triangle.

The Angle Bisector Theorem states: (x/22.5) = (6/9)

Solving for x, we get: x = (22.5 * 6/9) = 15

So the length of the third side of the triangle is 15 cm.

This is the only possible length for the third side of the triangle because the Angle Bisector Theorem only holds if the angle bisector is also a median to the side opposite of that angle.
