Answer:
It should be D.
Step-by-step explanation:
The matrices are
S =(4 11 T= ( -8 11
-3 -8) 3 4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
ST will be
( 4 11 × (-8 11 = ( 1 0
-3 -8) -3 -4) 0 1)
and also TS
( -8 11 × (4 11 = ( 1 0
-3 -4) -3 -8) 0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I
.
F(3) = 16, you simply plug in 3 for x to find the answer.
So decrease is 375-250=75
so convert 75/375 to percent
percent means part out of 100 so
x/100=x%
divide 125/375=0.3333/1
multiply by 100/100=33/100=33%
the answer is 33% or B
The shape of a basket ball is like sphere so use the formula of sphere vol.= 4/3*pie*r3 find the radius by r=D/2
