How do I do these questions?

Mathematics
1 answer:
yan [13]3 years ago
4 0

Step-by-step explanation:

The imaginary part of the number is where i is being multiplied by a constant. The real part is where there is no i present. I'll do a few examples.

26. The real part is 0, since there are no terms that don't have i. The imaginary part is 8i, since i is being multiplied by 8.

27. The real part is 7, since there is no i. The imaginary part is 3i, since i is being multiplied by 3.

31. The real part is 52, since there is no i. The imaginary part is 0i, since i is being multiplied by 0. You don't see the i because zero times i is zero.

M=7,r=8, t=2 ; mr/t = what
galina1969 [7]

Answer:

28

Step-by-step explanation:

Plug in the corresponding numbers to the corresponding variables. Note that:

m = 7

r = 8

t = 2

mr/t = (7 * 8)/2

(7 * (8/2)) = 7 * 4 = 28

28 is your answer.

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______
BlackZzzverrR [31]

Answer:

50

Step-by-step explanation:

from the question that we have been given, we have to find out the next number after 36.

John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.

This can be seen below:

14 + 8 = 22

14 +22 =36

14 +36 =50

therefore the next sequence would be 50

Find the perimeter of a triangle with vertices A(3, 1), B(2, -1), and C(-3, 2). Leave
natulia [17]

The perimeter of triangle is: 14.15 units

Step-by-step explanation:

First of all we have to find the lengths of sides of triangles

Given

A(3, 1), B(2, -1), and C(-3, 2)

The distance formula will be used to find the lengths of sides

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\

So,

AB = \sqrt{(2-3)^2+(-1-1)^2}\\=\sqrt{(-1)^2+(2)^2}\\=\sqrt{1+4}\\=\sqrt{5}\\=2.24\ unitsBC = \sqrt{(-3-2)^2+(2+1)^2}\\=\sqrt{(-5)^2+(3)^2}\\=\sqrt{25+9}\\=\sqrt{34}\\= 5.83\ units\\AC = \sqrt{(-3-3)^2+(2-1)^2}\\=\sqrt{(-6)^2+(1)^2}\\=\sqrt{36+1}\\=\sqrt{37}\\=6.08\ units

The perimeter of triangle will be:

P = AB+BC+AC\\= 2.24+5.83+6.08\\=14.15\ units

Hence,

The perimeter of triangle is: 14.15 units

Subtract. Express your answer in simplest terms. 3/4 - 3/5
bazaltina [42]
3/4 - 3/5

common denominator is 20

15/20 - 12/20 = 3/20

3/20 is your answer

multiply the opposite denominator with current numerator to get your new numerator number
