Answer:
49.2
9
Step-by-step explanation:
7.46² - 2.54² = (7.46 - 2.54)(7.46 + 2.54)
= (4.92)(10)
= 49.2
(1 x 4) x 3 = [1² + √(1 x 4)] x 3 = [1 + √4] x 3 = [1 + 2] x 3 = 3 x 3 = 9
Since it increases by 6%, that means you times the amount by an EXTRA 6%. I.e. 6220 x 1.06 = $6593.20
34.6 we do this because if our second number after the decimal point is 5 or higher we round up because we are passed the halfway mark and this means we are closer to the higher number

Answer:
x = 100
Step-by-step explanation:
We have to solve a logarithmic equation of x by changing it to exponential form.
Now, the logarithmic equation is 
⇒ 
{Since 'log' means there will be base 10}
Hence, converting from logarithmic to exponential form of equation we get,
{Since, we know that if
, then we can write
}
⇒ x = 100 ( Answer )
