Answer:
x+16
Step-by-step explanation:
For this one the negative signs become positive because, if you multiply a negative number*a negative number it becomes positive. That is a rule.

Answer:
option D

Step-by-step explanation:
Given in the question are 4 number
5√1/3 - 
2 - 
9 + 

A Complex Number is a combination of a Real Number and an Imaginary Number
<h3>Example </h3>
a + ib
where a is real number
b is imaginary number
i is 'lota' which is √-1
<h3>So according to the definition above </h3>
is complex number in which
is real part
=
is the imaginary part
Answer:
t = ln(0.5)/-r
Step-by-step explanation:
The decay rate parameter is missing. I will assume a value of 4% per day.
The exponential decay is modeled by the following equation:
A = A0*e^(-r*t)
where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).
At half-life A = A0/2, then:
A0/2 = A0*e^(-0.04*t)
0.5 = e^(-0.04*t)
ln(0.5) = -0.04*t
t = ln(0.5)/-0.04
t = 17.33 days
In general the half-life time is:
t = ln(0.5)/-r
Answer:
2321 ft.
Step-by-step explanation:
When Cai traveled from New Orleans to the Ozark Mountains in Arkansas the elevation changes from 7 ft below sea level to 2314 ft above sea level.
If we consider the elevation below sea level as negative and the elevation above sea level as positive, then the elevation changes from - 7ft to +2314 ft.
Therefore, the increment of elevation is by [2314 - (- 7)] = 2321 ft. (Answer)
