6 years
A parent increases a child’s monthly allowance by 20% each year. If the allowance is $8 per month now. This is an exponential function, An exponential function is given by:
Let x be the number of years and y be the allowance. The initial allowance is $8, this means at x = 0, y = 8
Since it increases by 20% each year, i.e 100% + 20% = 1 + 0.2 = 1.2. This means that b = 1.2
Therefore:
To find the number of years will it take to reach $20 per month, we substitute y = 20 and find x
x = 6 years to the nearest year
Answer:26
Step-by-step explanation:

well, we know the common difference is -3, to go from the 4th term to the 8th term, we need to add "d" 4 times or namely 3+4(-3), likewise to go from the 13th term to the 19th term we have to add "d" 6 times, or namely -24 + 6(-3).

SA=2LW+2WH+2HL
SA=2(8*3)+2(3*5)+2(5*8)
SA=158 cm
Answer:
32%
Step-by-step explanation:
The slope of the road is measured as
slope =
= 
To express as a percentage multiply the fraction y 100% , that is
slope =
× 100% = 16 × 2 = 32%
