(2+2i)(5+3i)
10+6i+10i+6i^2
10+16i+6(-1)
4+16i
When you have an “i^2”, you also have a negative one. The simplified answer is 4+16i
Answer:
D. Expression for Nick's distance from starting point= 6+(-4)+2
Step-by-step explanation:
Finding expression for each scenario:
A.
Number of boxes processed on on Monday =6 boxes
Number of boxes processed on on Tuesday =4 boxes
Number of boxes processed on on Wednesday =2 boxes
Expression for total boxes processed on these 3 days = 
B.
Temperature of Suma's city at noon = 6°C
Temperature of Suma's city at 8pm = 4°C
Temperature of Suma's city at noon next day = 2°F
Total temperature change = cannot be determined as all measurements are not in same units.
C
Money put on Monday = $6
Money put in Wednesday =$4
Money withdrew on Saturday = $2
Expression for balance of Re'onna's piggy bank = 
D
Distance ran north =6 miles
Distance ran south(back) = 4 miles
Distance ran north again = 2 miles
Expression for Nick's distance from starting point= 6+(-4)+2
Answer with a Step-by-step explanation: We are given the table as:
x f(x)
0 6
2 7
4 0
7 5
i.e. corresponding to different values of x we are given the values of f(x)
we have to find the value of f(0)
i.e. we have to find the value of f(x) when x=0
As we can see from the table the value of f(x) at x=0 is 6
Hence, Correct option is:
C) 6
Answer:
37.5
Step-by-step explanation:
if it decreases by 1/2 every 8 hours;
( 3×8= 24)
the first 8 hours 1/2×300 =150 gram
the second 8 hours(16 hours) = 1/2×150=75 gram
the third 8 hours(24 hours) = 1/2×75= 37.5gram
Answer:
Step-by-step explanation:
Let X be average interest paid monthly by a bank's Visa cardholders
Given that X is N(28, 8)
In the following to find out probability we convert X to z score and use std normal distribution table
Z = 
Probability being less than 1 is here equal to the proportion also.
A) P(X>32) = P(Z>0.5)=0.5-0.1915=0.3085
B) P(X>40) = P(Z>1)=0.5-0.3413=0.1687
C) P(X<19) = P(Z<-1.125)=0.5-0.0438=0.4562
D) We have to find 19th percentile here
Z =-0.88
