Explanation:
Simulate (build a table) the growing of the number of pennies for some nights to figure out the pattern:
First night:          1 penny = 2⁰
Second night:    1 × 2 pennies = 2¹
Third night:        2 × 2 = 2²
Fourth nigth:      2² × 2 = 2³
nth night:           2ⁿ⁻¹
You want 2ⁿ⁻¹ ≥ 2,000,000,000
Which you solve in this way:
- n-1 log (2)  ≥ log (2,000,000,000)
- n - 1  ≥ log (2,000,000,000) / log (2)
Since n is number of days, it is an integer number, so n ≥ 32.
Hence, she will have a total of more than $ 2 billion after 32 days.
You can prove that by calculating 2³² = 2,147,483,648.
 
        
             
        
        
        
Answer:
B.
Step-by-step explanation:
(-7x + 4)(-7x - 4)
= 49x^2 - 28x + 28x - 16
= 49x^2 - 16.

if u were discounting something, you would do ( .discount amount x original price ) - original amount! you will get a “-“ with the answer, just remove the “-“!!
