Answer:
2
Step-by-step explanation:
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:
A
Step-by-step explanation:
the end of interval is t=2
v=s'= -3t^2+4t-2
v(2)= -3(2^2)+4(2) -2
v(2)=-12+8-2
v(2)= -6m/s
so tje ans is A
Answer:
y = In(x)-5
Step-by-step explanation:
y = In(x)-5 is the correct choice. That -5 translates the graph of y = ln x downward by 5 units.
2 49/100 in decimal form is 2.49 because a decimal in the one hundredths would be like this: 0.09 or 0.49, and the two is a whole number, so it would go before the decimal like this: 2.09 or 2.49.
Hope this helped:):)
