Answer:
The answer to your question is below
Step-by-step explanation:
When using scientific notation,
- when we move the decimal point to the right, the power will be negative.
- when we move the decimal point to the left, the power will be positive.
a) 0.00001 move the decimal point 5 places to the right 1 x 10⁻⁵
b) 0.001 move the decimal point 3 places to the right 1 x 10⁻³
Well in this problem we just have to work backwards doing everything opposite of what she did in order to get the final answer.
so she has 39 stamps at this moment. and since she bought nine more stamps lets subtract that value to see what she had before that.
1.) 39 - 9 = 30
now she has 30. but she said that before step one she sold half of them to buy that video game. so she divided her starting number by two. so again we are going to work backwards by multiplying the number by 2:)
2.) 30 x 2 = 60!!
3.) So she started out with 60 stamps
answer is 60:)
hope i helped
Step-by-step explanation:
The correct answer is 5i
B² - 4ac
= 8² - 4*(-2)*(-9)
= 64 - 72
= -8
