5a to the power of 2 ofc
Step-by-step explanation:
Adding and subtracting are used in Please excuse my dear aunt sally, which if u never heard of this the P is for parentesies, E is for exponents, M stands for multiplication, D stands for Division, A is for adding, and S is for subtraction.
Also u use it during order of operations
You can use it for solving for a variable.
Answer:
You should have $1,463.95
Step-by-step explanation:
The formula for this is A=P(1+r)^x
P being the initial amount, r being the percentage, and x being the time passing.
<u>1. Write out the equation:</u> A=1400(1+0.015)^3
REMEMBER- writing percentages into decimals is moving the decimal point two times to the left--or dividing by 100!
<u>2. Parentheses:</u> 1400(1.015)^3
At this point, you're going to want to do exponents first (PEMDAS). If you're typing this into a calculator it should just give you the answer right away with the full equation.
<u>3. Answer:</u> 1463.95 (rounded to the nearest hundredth).
**I apologize if this is wrong; I haven't done it in a while so I don't know if I did 3 years or 3 months.. lol. That's probably not helping with the confidence level, but good luck!

length of 1 bacteria = 300 = 3 *10^2 nanometers
= 3 * 10^2 / 1 * 10^9 m
= 3 * 10^(2-9)
= 3 * 10^-7 m
