Answer: Exponential Function
Step-by-step explanation: This is a(n) exponential function becuase each input is going at a constant rate of x^2 which is an exponent. Meaning the output is squared by the given number (which is x).
Make me brainliest if it is right.
-3n is negative when the value of n is positive. When the value of n is negative, the value of -3n is positive. Remember that when multiplying a positive and a negative, the product will be negative. If you are multiplying two numbers with the same sign, the product will be positive.
The subtraction of complex numbers
is cos(π)+i sin(π).
Given
[cos(3π/4+i sin(3π/4) and
=cos (π/2) +i sin(π/2)
We have to find the value of
.
A complex number is a number that includes real number as well as a imaginary unit in which
. It looks like a+ bi.
We have to first solve
and then we will be able to find the difference.

[ cos (3π/4)+i sin (3π/4)]
[cos(π-π/4)+ i sin (π-π/4)]
=
[-cos(π/4)+sin (π/4)]
=
(-1/
+1/
)
=
=0
cos(π/2)+i sin (π/2)
=0+i*1
=1
Now putting the values of
,

=-1
=-1+i*0
=cos (π)+i sin(π)
Hence the value of difference between
is cos(π)+i sin(π).

Answer:
40π/3 cm^2
Step-by-step explanation:
The centerline of the shaded region has a radius of 3 +4/2 = 5 cm. Its length is 1/3 of a circle with that radius, so is ...
length of centerline = (1/3)(2π·5 cm) = (10/3)π cm
The shaded region is 4 cm wide, so the area is the product of that width and the centerline length:
(4 cm)(10/3 π cm) = 40π/3 cm^2
