Answer:
c
Step-by-step explanation:
I set it up as a ratio with hours on the top and the fraction of the job on the bottom. It looks like this: 5/(2/3) / x/1, because 1 is the whole job if 2/3 is only a fraction of it. Cross multiplying gives you 2/3x = 5. Solving for x gives you that it will take 7.5 hours to complete a whole job if it takes 5 hours to complete 2/3 of it.
(4 – 2i)(6 + 2i)
FOIL
First : 4*6 =24
Outer: 4*2i = 8i
Inner: -2i* 6 = -12i
Last: -2i*2i = -4i^2 =-4(-1) =4
Add together
24+8i-12i+4
28-4i
Answer: 28-4i

Answer:
<h2>124.51%</h2>
Step-by-step explanation:
In this problem, we are expected to solve for the percentage change, given the opening point and the closing point
given that the low is 4014
and the high is 9012
the formula to calculate the percentage change is given as
%change= (high-low)/low*100
substituting our given data we have
%change= (9012-4014)/4014*100
%change= (4998)/4014*100
%change= (1.2451)*100
%change= 124.51%
The total change in the stock market from the beginning of the day to the end of the day is 124.51%
