Answer:
1 - 5i
Step-by-step explanation:
(-2 + 4i) + ( 3 -9i) = -2 + 4i + 3 - 9i
= -2 + 3 + 4i - 9i
= 1 - 5i
Answer:
20
Step-by-step explanation:
sin(28) sin(x)
---------- = -----------
7 5
sin(28)* 5 = 7sin(x)
---------------------------
7
sin(28) * 5
---------------- = sin(x)
7
You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).
sin(28) * 5
sin^-1 (------------------) = x
7
Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)
Hope this helps.
First, determine the amount that the encyclopedia salesman earned from commission by multiplying 11% by $35,100.
Commission = ($35,100)(0.11)
Commission = $3,861
Adding up the base pay of $23,900 his total earnings would be,
Total earnings = $23,900 + $3,861
Total earnings = $27,761
<em>Answer: $27,761</em>
Answer:
2109.6 ≤ x ≤ 4383.56
Step-by-step explanation:
It is given that, there are 770000 to 1600000 gallons of blood circulation by the heart through a person's body every year.
Now, a year contains 365 days.
So, the human heart circulates from (770000/365) =2109.6 (Approximate) to (1600000/365) =4383.56 (Approximate) gallons of blood every day through a person body.
Hence, the inequality can be written in terms of x as,
2109.6 ≤ x ≤ 4383.56,
where x is the number of gallons of blood that is circulated by the heart through the body in a day. (Answer)
