Answer:
it will take 6 hours to fall to 50 degrees, but it will take 7 hours to fall below 50 degrees.
Step-by-step explanation:
take 71 on your calculator and just subtract 3.5 until you get to 50 or below.

Answer:
2.3
Step-by-step explanation:
Divide 785 by 345 and round it to the nearest tenth.
Answer:
y=-5x+1 (without point p)
Step-by-step explanation:
Identify the slope of y= -1/5x+2:
m=1/5
*The perpendicular slope is the negative reciprocal of the given slope, in this case 1/5 is that given slope.*
So, the slope of the line perpendicular would be:
mp(slope perpendicular)= -5
Then you construct the line equation with just a general b in this case which gives you the equation:
y= -5x+1
The equation is then put into standard form to find the equation for point p (not positive if this what was meant by the question if so this'll give you the correct answer) ax+by=c :
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.
