You just have to think what is 40% of 100 which is 40 then multiply 40 2 times to find out the answer four 40% of 200 when you do 40x2 it =80 so the answer is 80
Answer:
<em>The voltage at the middle source is</em> 
Step-by-step explanation:
<u>Voltage Sources in Series</u>
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:



The sum of these voltages is:

Operating:

We know the total voltage is
, thus:

Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is 
The correct answer is C, if you use the distributive property and multiply all of them by each other you would get x^3+2x^2+3x+6.
Hope this helps :-)
Answer:
Step-by-step explanation:
Let's retype that as y = b^x. The inverse of this function is log y = x
b
which you could also write as y = ln x
b
If you had y = e^x, the inverse function would be y = ln x.
Note that if you let ln x be the input to y = e^x, the result would be just 'x,' which confirms that these two functions are inverses of one another.
Answer:
a. y < 5
b. y < 24
c. y > 3
d. y < 30
Step-by-step explanation:
a. 12y < 60
12y/12 < 60/12
y < 5
b. y/8 < 4
8/1 * y/8 < 4 * 8/1
y < 24
c. 3y > 9
3y/3 > 9/3
y > 3
d. y/5 < 6
5/1 * y/5 < 6*5
y < 30
