Answer:
w = ![\sqrt{147}](https://tex.z-dn.net/?f=%5Csqrt%7B147%7D)
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
w² + 7² = 14²
w² + 49 = 196 ( subtract 49 from both sides )
w² = 147 ( take the square root of both sides )
w = ![\sqrt{147}](https://tex.z-dn.net/?f=%5Csqrt%7B147%7D)
Answer:
A
Step-by-step explanation:
Because 7000*1.09= 7630
and 5000*1.11= 5550 which are both equal to the amount each account will have after one year where they have gained interest.
In the first account 7630-7000=630 and the second 5550-5000=550
which is how much each gained in interest. together that makes 630+550=1180 in interest.
