Answer:
22.8906 sq in
Step-by-step explanation:
SA of a sphere = 4 π 
r = 2.7 / 2 = 1.35
4 x 3.14 x 
= 22.8906
Answer:
The answer would be that All the powers have a value if 1 because the exponent is zero.
Step-by-step explanation:
Use the exponent rule to help you
Ans:
(x+5)(x+1)+8
Step by step explanation:
-5 was mentioned as the 0 of the first root: (x+5). Then with some maneuvering we can plot (-3,4) then add (x+1) because they land on the same y axis. then we add 8 to get it right on the vertex.
This is the identity property of addition.
It states that any number added to 0 is itself.
The given set of equations:
y=-3x+1............(1)
y=2x-4 .............(2)
can be solved most conveniently by rewriting as
y =-3x+1 = 2x-4
We concentrate on the right equality, which is expressed in x only:
-3x+1 = 2x-4
Transpose and solve for x
1+4 = 2x+3x
5x=5
x=5/5=1
Substitute x=1 in the
first equation: y=-3(1)+1=-2
second equation: y=2*x-4=2(1)-4=-2
So the solution is x=1, y=-2, or (1,-2)
