What is the midpoint between z1 = -8 + 3i and z2 = 4 + 7i?

I am Lyosha [343]

Answer:

Therefore, Mid point : -2+5i.

Step-by-step explanation:

Given : Z1 = -8 + 3i and Z2 = 4 + 7i.

To find : What is the midpoint.

Solution : We have given Z1 = -8 + 3i and Z2 = 4 + 7i.

Mid point : $\frac{z_{1}+z_{2}}{2}$ .

On plugging the values.

Mid point : $\frac{-8+3i + 4 +7i}{2}$ .

Combine like terms.

Mid point : $\frac{-8+4+3i +7i}{2}$ .

Mid point : $\frac{-4+10i}{2}$ .

Mid point : -2+5i.

Therefore, Mid point : -2+5i.

400 ml of squash is made by mixing 50 ml of cordial with water. What fraction of the drink is water?

avanturin [10]

Answer:

Fraction of drink that is water = = 0.875 = 87.5 %

Explanation:

400 ml of squash is made by mixing 50 ml of cordial with water.

Total volume of squash = 400 ml

Total volume of cordial = 50 ml

Total volume of water = 400 - 50 = 350 ml

Fraction of drink that is water = Volume of water/ Volume of squash

= 350/400

= 7/8

= 0.875 = 87.5 %

On a number line, suppose the coordinate of A is 0 and AR=21. What are the possible coordinates of the midpoint of AR?

Gnoma [55]

Answer:

The possible coordinates of the midpoint are -10.5 and 10.5

Step-by-step explanation:

The given parameters are;

The coordinate of A = 0

The distance from A to R which is the same as AR = 21

Given that R is on the number line, we have;

When R is on the left side of A, which is = 0 - 21 = -21, we have;

The coordinates of the midpoint, M from -21 to 0 is given as follows;

M = (A + R)/2 = (0 - 21)/2 = -10.5

When R is on the right side of A, which is = 21 - 0 = 21, we have;

The coordinates of the midpoint, M from 21 to 0 is given as follows;

M = (A + R)/2 = (0 + 21)/2 = 10.5

Therefore, the possible coordinates of the midpoint are -10.5 and 10.5.
