Answer:
61.13
Step-by-step explanation:


X = log (base b) y
The base of the log becomes the base of the exponent.
The x and y switch.
b^x = y
Answer:
80.5 kilometers/h
Step-by-step explanation:
S=80.5km/h
D644
T8 hours
W - a width
3w - a length
27 ft² - an area
Therefore:
w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3
3w = 3 · 3 = 9
width = 3
length = 9
The perimeter:
P = 2 · width + 2 · length
P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
A graph shows the appropriate choice to be
A. 277.8 °F
_____
Of course, you get the same result by evaluating
76 + 301*e^(-0.40)
