Answer:

The conjugate is 2+5i and the product is 29.

Step-by-step explanation:

The conjugate of a complex number a+bi is a-bi

Our complex number is 2-5i.

Here, a = 2 and b = -5

Thus, the conjugate of 2-5i is

2-(-5i)=2+5i

Using this rule:

(a+b)(a-b)=a^{2}-b^{2}

And the fact that i^{2} = -1

We can find the product of any complex number and its conjugate:

(a+bi)(a-bi)=a^{2}  - (bi)^{2}=a^{2}  - b^{2} i^{2}  = a^{2}  + b^{2}

As our complex number is 2-5i, the product with its conjugate will be

2^{2} + (-5)^{2} =4+25=29

Y varies directly with x and y=8 when x=-5
ale4655 [162]

Answer:

Y=K×X...... equation

When,Y=8 and X=-5

To find the constant (K)

we substitute for K in the equation

8=K×-5

8=-5K divide both sides by -5

8÷-5=-5K÷-5

K=-1.6

The data reflects the number of hours an employee spends working a checkout line (x), paired with the number of customers served
Whitepunk [10]

The slope of the line can be interpreted that with each additional hour, nearly 18 customers are served; option B

<h3>What is the slope of a line?</h3>

The slope of a line is the ratio of climb to that of run

Slope = change in y/change in x

The given graph is a graph of the number of hours an employee spends working a checkout line (x), against the number of customers served (y).

The slope of the graph can be written as follows:

Slope = change in the number of customers served/change in the number of hours an employee spends working

Therefore, the slope of the line can be interpreted that with each additional hour, nearly 18 customers are served.

In conclusion, slope of a line is ratio of change in y to change in x.
