What is the value of the expression given below?
(5 + 3i) - (5 + 3i)(5 – 5i)
a. –5 + 371
b. 35 – 131
oc -5 – 371
d. –35 + 131

D. -35+13i

Step-by-step explanation:

We have the expression , first we have to solve:

we have to apply distributive property.

Distributive property:

Then,

Observation: then

Now replacing in :

Then the correct answer ir: D. -35+13i

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
