Answer:
f-1(x) = log2 [ (x + 4)/3 ] - 3.
Step-by-step explanation:
Let y = 3(2^(x+3) - 4
3(2^(x + 3) = y + 4
2^(x + 3) = (y + 4)/3
x + 3 = log2 [(y + 4)/3]
x = log2 [ (y + 4)/3 ] - 3
Inverse f-1(x) = log2 [ (x + 4)/3 ] - 3
Answer:
6.5
Step-by-step explanation:
Each term in this sequence is the previous term divided by -2:
104/-2=-52
-52/-2=26
26/-2=-13
So in order to find the next term, we just need to divide the last term by -2:
-13/-2 = 6.5
The next term in the sequence is 6.5
Hope this helped!
Answer:
507 miles
Step-by-step explanation:
If each gallon can go 39 miles and the max number of gas it can hold is 13 gallons, then all you have to do is multiply 13 x 39, which equals 507
Answer:
86.5 m
Step-by-step explanation:
Length of the string forms the hypotenuse AC of right angle triangle ABC.
C is the kite. A is the hand of the person (or, one end of the string). CB is the perpendicular (height of the kite ) from C on the ground. BC is the horizontal.
Sin 60° = CB/AC = √3/2
height = 1.73/2 * AC = 0.865 * 100 m = 86.5 m
