Answer:
<h3>-42</h3>
Step-by-step explanation:
given the expression;
(2+√-25)(4-√-100)
Note that √-25 = √-1 * √25
√-100 = √-1 * √100
According to complex number, √-1 = i
√-25 = 5i
√-100 = 10i
The expression becomes
(2+5i)(4-10i)
Open the parentehsis;
= 2(4)-20i+20i-50i²
= 8-50i²
Since i² = -1
The expression becomes;
8-50i² = 8-50(-1)²
8-50i² = 8-50 = -42
Hence the product of the expression is -42
Answer:
Step-by-step explanation:
From the question we are told that
Homicide rate in US 
Homicide rate in Britain 
Generally the equation for probability of homicide is mathematically given as
Generally the equation for probability of homicide in US is mathematically given as
Generally the equation for probability of homicide in Britain is mathematically given as
a)Generally the difference b/w the probabilities P_D is mathematically given as
Therefore US annual homicide is greater than Britain's
b)Generally the Relative risk is R_r is mathematically given as
2x + 1 + 5x + 5 + 90 = 180
7x + 96 = 180
7x = 180 - 96
7x = 84
x = 12
The distance that will separate each rest stop is 4 kilometers.
<h3>What is the distance?</h3>
Division is the process of parting a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.
The distance = length of the trail / number of rest stops
20 km / 5 = 4km
