Using a graph tool
see the attached figure
<span>let's graph all the cases to verify the answer
case A) f(x)=(3</span><span>^x)-2
case B) </span>f(x)=(4^x)-2
case C) f(x)=4^(x-2)
case D) f(x)=4^(x-2) +2------> this is the solution
the answer is the option D
Answer:
4.167(10²)
Step-by-step explanation:
Step 1: Put number into proper decimal form
416.7 = 4.167
Step 2: Figure out exponent
Since we are moving the decimal places 2 places to the right, our exponent is 2
Answer:
1.) 
2.)
3.)
4.)
5.)
6.) 
Step-by-step explanation:
I did 6 problems for you. You can now do the other 4 problems and see how I did it. You need to have the same denominator and the add the fractions together.
rules to find :- 1 All non zeroes number are significant
2 if zero proceeding the decimal point also work as non zero figure
3 zero are following the decimal point and proceeding the first non zero digit
4 Zero in between 2 non zero digits are also significant
5 if 1 zero follow the decimal point
790 :- 2 significant figures
0.0391 :- 3 significant figures ( follow 3 rule)
81.05 :- 4 significant figures ( rule 4)
0.000001 :- 1 significant figure
8546 :- 4 significant figures
79.0 :- 3 significant ( rule 5)
A=7,500×(1+0.06÷4)^(4×2)
A=8,448.69
Interest earned=8,448.69−7,500
Interest earned=948.69
