The answer is
51-17i
Explanation :
5x95x2i-3ix9-3ix2i
45+10i-27i-6^2
45+10i-27i-6(-1)
45+10i-27i + 6
Not enough information to tell really but seems like both of those above should be your answer
Answer:
83x + 4
Step-by-step explanation:
9x^2 + 4 -x^2 + 3x
80x + 4 + 3x
83x + 4
Answer:
h = 4cm
Step-by-step explanation:
Diameter = 18cm
Radius = Diameter/2 = 18/2 = 9cm
V = 1/3*pi*r^2*h
We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.
So,
108 pi = 1/3*pi*9^2*h
108 pi = (81pi*h)/3
multiply 3 from both side
108pi*3 = (81pi*h)/3 *3
324pi = 81pi*h
Now divide the 81pi from both side
324pi/81pi = (81pi*h)/81pi
4 = h
So the height is 4cm
Answer:
x = 37.1003638138
Step-by-step explanation:
Use cos = adjacent/hypotenuse
cos41 = 28/x
Multiply x on both sides to get it out of the denominator.
x · cos41 = 28/x · x
Now you have
x · cos41 = 28
Divide both side by cos41 to get x by itself.
x · cos41/cos41 = 28/cos41
Now divide
x = 28/cos41
x = 37.1003638138
