A man selling computer parts realizes that when he sells 16 computer parts, his earning is $1700. When he sells 56 computer part
natta225 [31]

We need to find the unit rate. To do so, divide the amount of money he makes by the number of parts sold. 1,700 / 16 = 106.25. So, if the man sells one computer part, he gets $106.25. To find the price of 30 parts, multiply 106.25 by 30. 106.25 * 30 = $3,187.50

The man will make $3,187.50 if he sells 30 parts.

Find the distance between the points (-7,-6) and (5,-6) .
PilotLPTM [1.2K]

<u>Answer:</u>

12 units

<u>Step-by-step explanation:</u>

We are given these two points, (-7,-6) and (5,-6), and we are to find the distance between them.

We know the formula for finding the distance between two points:

<em>Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}</em>

So putting in the values of the given coordinates in the above formula to get:

Distance = \sqrt{(5-(-7))^2+(-6-(-6))^2} = \sqrt{144 + 0}  =12

Therefore, the distance between the two given points is 12 units.

The roots of the equation are 3 + 8i and 3 – 8i.
g100num [7]
Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73
