Answer:
17-i
--------
29
Step-by-step explanation:
To simply fractions with complex numbers, we have to multiply by the complex conjugate of the denominator.
The denominator is 5+2i, so the complex conjuate is 5-2i
3+i 5-2i
------ * ---------------
5+2i 5-2i
Simplifying the numerator
(3+i) * (5-2i) = 3*5 + 5i -3*2i -2i^2 = 15 +5i -6i -2(-1) = 15-i+2 = 17-i
Simplifying the denominator
(5+2i) (5-2i) = 25 -10i + 10i -4i^2 = 25 -4(-1) = 29
17-i
--------
29

If the highest temp. it will get in the day is 75 and it is 56 then all u do is 75-56 to get 19, so it will increase 19 degrees if it gets to 75 degrees during the day.
Answer:
6
Step-by-step explanation:
if we always go from right to left it will start with lin segment BC BD BA CD CA and DA those are all the posible segments for this line
<u>For W, </u><u>W = 28B.</u>
Given that one concrete block is 28 pounds, and that B is the number of blocks, we can multiply both values to get the amount of pounds, or weight, of the quantity of B blocks. So <em>W = 28B.</em>
<u>For B, </u><u>B = W ÷ 28</u>
Now that we know the equation for the weight, W = 28B, we can divide both sides by 28 to isolate the variable, B. The equation now becomes <em>B = W ÷ 28. </em>
