If 2 ^ n / 2 is equals to 1024 then n is equals to dash

n = 11.

Step-by-step explanation:

2 ^ n / 2 = 1024

Multiply both sides by 2:

2^n = 2048

log 2^n = log 2048

n log 2 = log 2024

n = log 2048 / log 2

=  11 (answer).

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
