The increase is an exponential increase in a multiplier

and as decimal 1.0045
Final Value = Initial Value ×

Final value =

Final value = 393 mg (to the nearest whole number)
Half life = 0.5 years
Final value =

=301 mg
Commutaive property says
ab=ba or expanded to say
abc=cba
associative peropty =
a(bc)=(ab)c
so using that
first mix them up knowing that we can move the parenthaseese
all possible equivelnt ones are
4*(5*3)
(3*5)*4
3*(5*4)
(3*4)*5
3*(4*5)
5x+2y=20
Substitute 0.3 for x
5(0.3)+2y=20
Multiply 5 by 0.3
1.5+2y=20
Subtract 1.5 from both sides
2y=18.5
Divide 2 on both sides
Final Answer: y= 9.25
Yes.
a test for a function is the vertical line test, so think about drawing a vertical line on top of this picture. if at any point the line is touching the graph more than once, it is not a function. this graph passes the vertical line test
