Answer:
(7-5i)( 2+3i)
=7(2)+ 7(3i)-5i(2) -(5i)(3i)
= 14 +21i -10i +15
= 29 +11i
I'm reading this as ..... 36o more then the measure of its complementary angle.
x = 90 - x + 36 add 90 and 36 together.
x = 126 - x Add x to both sides.
2x = 126
x = 126 /2
x = 63
The complementary angle is 90 - 63 = 27
The question is is 63 36 bigger than 27
27 + 36 = 63 and the angles are
Answer 27o and 63o
The slope (change in y/change in x) of the line is (1560 - 1200)/(52 - 40), which is equal to 30. We can plug this into the equation y = mx + b using either the point (40, 1200) or (52, 1560). The slope is represented by m and the y - intercept by b. Therefore, the two possible equations you could use are:
1200 = 30(40) + b
or 1560 = 30(52) + b
Using either equation, you'll get that b is equal to 0, which makes sense in the context of the problem, since it's reasonable to expect that the labor expenses would be 0 for 0 hours worked.
