Answer:
x=1
Step-by-step explanation:
Take the root of both sides and solve
Answer:
C=3.14*32=100.48mm
Step-by-step explanation:
25.x2+9= 59
(5.2+3i)2= 10.4+6i
(5.2-3i)= 5.2-3i
the truth is not very well understood the subject so I'm going to give you these answers and you tell me if they are good or bad?
The shape of the water is that of a "spherical cap." The formula for the volume of a spherical cap is ...
... V = π·h²·(r -h/3) . . . . . . . from web search
For a radius of 5 in, this is
... V = π·h²·(5 -h/3) . . . . in³
_____
For h=0
... V = π·0²·(5 -0/3) = 0
For h=5 in
... V = π·(5 in)²·((5 -5/3) in) = (2/3)π·5³ in³ . . . . . the volume of a hemisphere of radius 5
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
