Let "per month" = m

The inequality is

1.5m + 4 ≥ 7

+ 4: Her hair right now is 4 cm long

1.5m: Her hair grows 1.5 per month (m)

≥ 7: She wants it to be at least 7 or more.

1.5m + 4 ≥ 7 is your answer

hope this helps

At the beginning of year 1, Josie invests $400 at an annual compound interest
zvonat [6]

Answer:

The explicit formula that can be used is A=\$400(1.05)^{2}

The account's balance at the beginning of year 3 is A=\$441  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=2\ years\\ P=\$400\\ r=0.05\\n=1  

substitute in the formula above  

A=\$400(1+\frac{0.05}{1})^{1*2}  

A=\$400(1.05)^{2}

A=\$441

C(n,r)=[?]

C(n,r)=C(5,3)

=\frac{5}{(3!(5-3)!)}

=\frac{5!}{3!*2!}
