Answer:
FYAB gives a better deal.
Step-by-step explanation:
Compound interest:
Continuously compounded interest:
For the quarterly compounded interest, r = 0.25%, and n = 4.
For the continuously compounded interest, r =0.23%
The quarterly compounded doubles in 277 years.
The continuously compounded doubles in 301 years.
Answer: FYAB gives a better deal.
Answer: A = 5
The Wise Orange found an image that may be helpful:
For the first one,
you multiply 5x and -5 to get -25.
Then you move the constant to the right and change the sign to get 3x= -21 +25.
Calculate the sum of -21+25 to get 4.
Divide both sides of the equation by 3 to get x=4/3.
So then your final answer is x=4

3
For the second one,
Distribute 7 through the parentheses to get 14x + 14+8=120
The you add 14+8 to get 22. Your equation should be 14x+22=120
Move the constant to the right side and change its sign to get 14x=120-22
Subtract 120-22 to get 98. Now your equation should be 14x=98
Divide both sides of the equation by 14 to get x=7.
Your finial answer for the second one should be x=7.

I hope this made sense.
= 36 x^6 / 9 x^8
= 4 / x^2
Its A
If we work it through:
70mph is 11mph less than 3 times the fastest running speed for a man.
So 70 + 11 = 81mph is 3 times the fastest running speed for a man.
Can you see where to go from here?
