Answer:

Terms are positive or negative single mathematical expressions.

Step-by-step explanation:

Step-by-step explanation:

remember, i = sqrt(-1)

you know what an exponent means, right ?

it means you multiply the enclosed term that many times with itself.

when you envision this as a long chain of (1+i)/(1-i) multiplications, you can see you can group them into pairs, and then multiply these pairs - just half the times than for the single terms.

so,

((1+i)/(1-i))²⁰²⁰ = ((1+i)/(1-i))² ^ 1010

to get an idea what the result of the long chain of multiplications might be, let's start with the square and see, if we can find a pattern, that we then can use to come to a conclusion about the total result.

((1+i)/(1-i))² = (1+i)²/(1-i)²

(1+i)² = 1×1 + 1×i + 1×i + i² = 1 + 2i - 1 = 2i

(1-i)² = 1×1 - 1×i - 1×i + i² = 1 - 2i - 1 = -2i

so,

((1+i)/(1-i))² = 2i/-2i = -1

aha !

so,

((1+i)/(1-i))² ^ 1010 = (-1)¹⁰¹⁰

just to be sure you understand, we use the same trick again

(-1)¹⁰¹⁰ = (-1)² ^ 505 = 1⁵⁰⁵ = 1

as 1 to any power is always 1.

so, the right answer is A.

remember, a negative number to an even power results always in a positive number. and to an uneven/odd power in a negative number.

again, because such an exponent is only the summary of many multiplications.

Answer:

x=25, y=19

Step-by-step explanation:

130+2x=180

x=25

54+2x+4y=180

y=19

Answer:

x = 25 , y = 19

Step-by-step explanation:

130° and 2x° are adjacent angles on a straight line and sum to 180° , so

130 + 2x = 180 ( subtract 130 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

--------------------------------------------------------------

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle , then

54 + 4y = 130 ( subtract 54 from both sides )

4y = 76 ( divide both sides by 4 )

y = 19

Answer:

x > 4

Step-by-step explanation:

hope this helps

Answer:

NO

NO

YES

NO

Step-by-step explanation:

The sum of the angles has to be equal to 180° because the sum of the angles in a triangle is 180°

The first one is already more that 180°, because you are adding 2 angles that are more than 100°

The sum of the second one is equivalent is 160°

The sum of the third one is equivalent to 180°

The sum of the fourth one is more than 180°

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Given the system of equation expressed as:

3x + y = 3

x - 2y = 4

Solve simultaneosly;

3x + y = 3 ............. 1 * 1

x - 2y = 4 ...............2 * 3

_________________________

3x + y = 3

3x - 6y = 12

Subtract

y-(6y) = 3 - 12

7y = -9

y = -9/7

Substitute y = -9/7 into the equation to get x

x - 2y = 4

x - 2(-9/7) = 4

x + 18/7 = 4

x = 4 -  18/7

x = 3/7

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Answer:

x = 12

Step-by-step explanation:

The sum of exterior angles is = 360

one of the angle is given we will need to add all three angles

128 + 8x + 11x + 4 = 360 add like terms

19x + 132 = 360 subtract 132 from both sides

19x = 268 divide both sides by 19

x = 12 replace x in required expressions to find the measure of the angles

Answer:

2

Step-by-step explanation:

3x + 7=15 -x

4x= 8

x= 2

3*2 + 7 = 15-2

8x - ¹/₃y = 16

8x - ¹/₃(0) = 16

     8x - 0 = 16

          8x = 16
