Answer:
The inverse function of f(x) is ... f⁻¹(x) = log (x/9.16)/log (1.0054)
Step-by-step explanation:
Starting equation... f(x) = 9.16(1.0054)ˣ
Visually rewritten... y = 9.16(1.0054)ˣ
Flipping x and y... x = 9.16(1.0054)ʸ
Isolating (1.0054)ʸ... x/9.16 = (1.0054)ʸ
Taking the log of both sides... log (x/9.16) = y log (1.0054)
Isolating y... log (x/9.16)/log (1.0054) = y
Solution... y = log (x/9.16)/log (1.0054)
Answer:
1 1/4 in of material is cut off each board.
Step-by-step explanation:
To answer this, subtract 7 ft 10 3/4 inches from 8 ft.
First, rewrite 8 ft as 7 ft 12 inches.
Then subtract:
7 ft 12 in
- 7 ft 10 3/4 in
----------------------
1 1/4 in
1 1/4 in of material is cut off each board.
71% water
29% land
71:29= 2,448=> the amount of earth surface that is covered with water is ~2,5 times bigger than the amount of earth surface that is covered with land
The answer to your problem is C
Answer:
(2x+5)(x+1)
Step-by-step explanation:
We look for two numbers which multiply to 10(that is 2×5) and add to 7. Our numbers are 2and 5
2×5=10 and 2+5=7
Therefore we have
(2x²+2x)+(5x+5)
2x(x+1)+5(x+1)
(2x+5)(x+1)
