Answer:
0.8%.
Step-by-step explanation:
Given:
At the start of the month, the value of an investment was $73.42.
By the end of the month, the value of the investment changed by a loss of $13.53.
Question asked:
What was the value, in dollars, of the investment at the end of the month?
What was the percent loss?
Solution:
At the start of the month, the value of an investment = $73.42.
Loss = $13.53.
<u><em>The value, of the investment at the end of the month = The value of an investment at the start of the month - loss</em></u>
The value, of the investment at the end of the month = $73.42 - $13.53
= $59.89
Thus, the value, of the investment at the end of the month is $59.89.
Now, we will find percent loss:-
Thus, percent loss on investment by the end of the month is 0.8%.
Short AnswerThere are two numbers
x1 = -0.25 + 0.9682i <<<<
answer 1x2 = - 0.25 - 0.9582i <<<<
answer 2 I take it there are two such numbers.
Let one number = x
Let one number = y
x + y = -0.5
y = - 0.5 - x (1)
xy = 1 (2)
Put equation 1 into equation 2
xy = 1
x(-0.5 - x) = 1
-0.5x - x^2 = 1 Subtract 1 from both sides.
-0.5x - x^2 - 1 = 0 Order these by powers
-x^2 - 0.5x -1 = 0 Multiply though by - 1
x^2 + 0.5x + 1 = 0 Use the quadratic formula to solve this.
a = 1
b = 0.5
c = 1
x = [-0.5 +/- sqrt(0.25 - 4)] / 2
x = [-0.5 +/- sqrt(-3.75)] / 2
x = [-0.25 +/- 0.9682i
x1 = -0.25 + 0.9682 i
x2 = -0.25 - 0.9682 i
These two are conjugates. They will add as x1 + x2 = -0.25 - 0.25 = - 0.50.
The complex parts cancel out. Getting them to multiply to 1 will be a little more difficult. I'll do that under the check.
Check(-0.25 - 0.9682i)(-0.25 + 0.9682i)
Use FOIL
F:-0.25 * -0.25 = 0.0625
O: -0.25*0.9682i
I: +0.25*0.9682i
L: -0.9682i*0.9682i = - 0.9375 i^2 = 0.9375
NoticeThe two middle terms (labled "O" and "I" ) cancel out. They are of opposite signs.
The final result is 0.9375 and 0.0625 add up to 1
Answer:
The final cost would be $42,780 for sending a 34 word telegram.
Step-by-step explanation:
1. $4050*10= $40,500
2. 34-10=24
3. 24*$95= $2,280
4. $40,500+$2,280= $42,780
Hope this helps! :)
