V=lengthxwidthxheight
v=2 1/2x2 1/2x 5
=31.25
35-31.25=3.75
The answer is 3.75cm³
L(t)=9-0.5t
t=time in hours,
L(t)=length of candle at time t
(A) substitute t=1,2,3,4,5,6 respectively to get
(1,8.5)
(2,8)
(3,7.5)
(4,7)
(5,6.5)
(6,6)
(B) it is a function because none of the x-values duplicate, (nor the y-values).
(C) If the rate changes to 0.45 "/hr, the relation is still linear.
All linear function with finite slope are functions.
Opposite number is the same number with the opposite sign:
So the opposite of
is
, since the original number is positive
opposite of
is
, since the original number is negative
Points: (0,4) and (2,-3)
Find slope: (-3-4)/(2) = -7/2
4 = -7/2(0) + b, b = 4
Equation: y = -7/2x + 4
