cupoosta [38]

Answer:

$c=8$

Step-by-step explanation:

Given: $y=ax^2+bx+c$

To find: c

Solution:

At $x=4,y=48$ :

$48=16a+4b+c$ (i)

At $x=5,y=73$ :

$73=25a+5b+c$ (ii)

At $x=6,y=104$ :

$104=36a+6b+c$ (iii)

On subtracting (i) and (ii),

$25=9a+b$ (iv)

On subtracting (i) and (iii),

$56=20a+2b\\\\28=10a+b \,\,\,\,(v)$

On subtracting (iv) and (v),

$a=3$

Put a=3 in (iv)

$25=9(3)+b\\25=27+b\\25-27=b\\-2=b$

Put $a=3,b=-2$ in (iii)

$104=36(3)+6(-2)+c\\104=108-12+c\\104=96+c\\104-96=c\\8=c$

How yo simplify (b2/3 x b5/3 x t1/5 x t3/4)?

lesantik [10]

$\bf a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} 
\qquad \qquad
\sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}}\\\\
-------------------------------\\\\$

$\bf b^{\frac{2}{3}}\cdot b^{\frac{5}{3}}\cdot t^{\frac{1}{5}}\cdot t^{\frac{3}{5}}\implies b^{\frac{2}{3}+\frac{5}{3}}\cdot t^{\frac{1}{5}+\frac{3}{5}}\implies b^{\frac{7}{3}}t^{\frac{4}{5}}\implies \sqrt[3]{b^7}\cdot \sqrt[5]{t^4}
\\\\\\
\sqrt[3]{b^{1+3+3}}\cdot \sqrt[5]{t^4}\implies \sqrt[3]{b^1b^3b^3}\cdot \sqrt[5]{t^4}\implies bb\sqrt[3]{b}\cdot \sqrt[5]{t^4}\implies b^2\sqrt[3]{b}\cdot \sqrt[5]{t^4}$
