If a-b=14,ab=8 find a^2+b^2

ycow [4]

Here,

a-b=14

ab=8

we know that,

$\tt{(a-b)^2=a^2+b^2-2ab }$ ⠀

According to the question, 

$\tt{ (14)^2=a^2+b^2-2×8 }$ ⠀

$\tt{196=a^2+b^2-16 }$ ⠀

$\tt{a^2+b^2=196-16 }$ ⠀

$\tt{a^2+b^2=180 }$ ⠀

A hot air balloon ascended to a height of 25 meters 2 minutes after launch. After some time, the balloon's altitude began to cha

DENIUS [597]

Answer:

18.1 m

Step-by-step explanation:

For this problem, we will simply use the initial height of 0 meters, the height of 25 meters after 2 minutes, the decline of 2.2 meters every minute for 7 minutes, and a final increase of 8.5 meters to find the final altitude of the ballon.

0m + 25m - 2.2m(7) + 8.5m = ?

25m - 15.4m + 8.5m = ?

9.6m + 8.5m = ?

18.1m = ?

Hence, the final altitude of the ballon is 18.1m.

Cheers.
