Find the product.
(9 - 5i)(4 + 6i)
a.
-30i2 + 34i +36
c.
6 - 74i
b.
66 - 34i
d.
66 + 34i

A)  -30i^2 + 34i + 36

Step-by-step explanation:

=(9 - 5i)(4 + 6i)

=(9 x 4) + (9 x 6i) + (-5i x 4) +  (-5i x 6i)

= 36 + 54i - 20i - 30i^2

= 36 + 34i - 30i^2

hope it will help you...

d. 66 + 34i

Step-by-step explanation:

took the test

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

its 50 miles away from the starting point
