Answer: -8.93
Step-by-step explanation:
Given the function:
N(X) = 90(0.86)^x+ 69
X in the interval [0, 6]
For X = 0
N(0) = 90(0.86)^0 + 69
90 + 69 = 159
For X = 6
N(6) = 90(0.86)^6 + 69
90(0.404567235136) + 69
= 105.41105116224
Therefore, average change of change in temperature ;
(temp 2 - temp 1) / ( time 2 - time)
(105.41105116224 - 159) / (6 - 0)
= - 53.58894883776 / 6
= - 8.93149147296
= - 8.93
Answer:
21
Step-by-step explanation:
(5x5) the big square - (2x2) the small square
25-4=21
Answer:
Domain is all real numbers.
Range is -3 to infinity that is y >= -3 (that is y -3)
Increasing from x > -4 ( that is from -4 to +infinity) that is to right of -4
Decreasing from x <-4 (that is -infinity to -4) that is to left of -4
This has a minima at x= -4 with y= -3. We can write as (-4, -3)
Maxima is not there as it is going to infinity

Answer:
26 hours
Step-by-step explanation:
speed = distance/time
s = d/t
st = d
t = d/s
t = (13 km)/(0.5 km/h)
t = 26 h
Answer: 26 hours
