Answer:
9 is the real part and 7i is the imaginary part
Step-by-step explanation:
A complex number is written in the form a+bi where a is the real part and bi is the imaginary part

7i is the imaginary part
Answer: 25percent
Step-by-step explanation: Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%
Note: you can convert easier from decimal form to percentage form by moving the decimal place two spaces to the right
please mark my answer as the brainliest
On a clock one rotation around the clock for 12 hours is 2pi, since the clock rotates for 36 hours that means that the clock rotates around the clock 3 times since 36/12=3. So 2pi*3= 6pi. Therefore the hour hand will rotate 6pi radians in 36 hours
Answer:
The third option is correct.
The domain of the function is given by

The range of the function is given by

Step-by-step explanation:
Sara bought a cell phone for $200 and its value has decreased at rate of $5 per month.
V(t) is the value of the phone and t is the number of months.
The domain of the function is the possible values of the number of months t.
The domain of the function is given by

The range of the function is the values of V(t) that we get after substituting the possible values of the number of months t.
The range of the function is given by

When the number of months is t = 0 then the value of the function is maximum V(t) = 200
When the number of months is t = 40 then the value of the function is minimum V(t) = 0
Therefore, the third option is correct.
2(x-2)=9
Hope this helps !! have a good day
