strojnjashka [21]

Answer:

The average rate of change is 1.275

Step-by-step explanation:

The average rate of change of f(x) from x=a to x=b is given by:

\frac{f(b)-f(a)}{b-a}

The money Terry invested is modeled by the function f(x)=0.01(2)^x where x represents number of days.

The average rate of change from day 2 to day 10 is given by:

\frac{f(10)-f(2)}{10-2}

f(10)=0.01(2)^{10}=10.24

f(2)=0.01(2)^{2}=0.04

The average rate of change becomes:

\frac{10.24-0.04}{8}

=\frac{10.2}{8}=1.275

Henry is 3 times older than Julia. Rhianna is 1/2 as old as Julia. What formula shows the relationship between Henry and Rhianna
Sedbober [7]
The answer is A because if you make up an age for Julia for example Julia is 6 years old. In that case we multiply her age by 3 to figure out Henry's age which is 18. Rhianna is half as old as Julia is so that would make her 3 years old. In order for Henry which he is 18 years old to get to Rhianna's age which is 3 years old. you just divide 18 by 3 which is 6 years old. therefore the answer is A
