0.5(x - 3) + (1.5 - x) = 5x
0.5x - 1.5 + 1.5 - x = 5x
-0.5x = 5x
5x + 0.5x = 0
5.5x = 0
x = 0
Differentiating the function
... g(x) = 5^(1+x)
we get
... g'(x) = ln(5)·5^(1+x)
Then the linear approximation near x=0 is
... y = g'(0)(x - 0) + g(0)
... y = 5·ln(5)·x + 5
With numbers filled in, this is
... y ≈ 8.047x + 5 . . . . . linear approximation to g(x)
Using this to find approximate values for 5^0.95 and 5^1.1, we can fill in x=-0.05 and x=0.1 to get
... 5^0.95 ≈ 8.047·(-0.05) +5 ≈ 4.598 . . . . approximation to 5^0.95
... 5^1.1 ≈ 8.047·0.1 +5 ≈ 5.805 . . . . approximation to 5^1.1
Answer:

Step-by-step explanation:
we are given two temperature
4 degrees and -10 degrees
since it says to figure out the changed
substract

remove parentheses and change its sign

simplify addition:

and we are done!
Answer:
72 novels
Step-by-step explanation:
A number of assumptions are involved regarding operating environment, utilization fraction, and probability of failure as a function of time. The precise meanings of the words "average", "supposed to last", "maximum", and "expect" are involved. The details are too arcane to go into here.
(450 hours)/(6 1/4 hours/novel)
= (450/(25/4)) novels
= (450*4/25) novels
= 72 novels
