The friend is wrong - According to the Pythagorean Theorm, if c is the hypotenuse and a and b are opposite sides then c^{2} = a^{2} + b^{2}
if c=65 inches, a=16 inches and b = 63 inches, then
65^{2} =16 ^{2} + 63^{2}
right hand side of the equation = 256 + 3969 = 4225
left hand side of the equation = 65^{2}= 4225
So we see, left hand side = right hand side
Hence the theorm is proved.
Answer:
[(8.-3),(3.8),(9,4),(-2,2)}
Step-by-step explanation:
Answer:
<em>x = 8 </em>
Step-by-step explanation:
3 ln 4 = 2 ln x ( <em>x > 0</em> )
ln 
= ln 
x² = 4³
x² = (2³)²
x = ± 2³
= 8
= - 8 ( strange root, does not satisfy the domain of given function )
<em>x = 8</em>
250 × 3 = 750
