Answer:

\frac{-5+/-\sqrt{42} }{8}

Step-by-step explanation:

The quadratic formula is x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}. Here a=4, b=5, and c=-1.

Substitute and you'll have:

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{-5+/-\sqrt{5^2-4(4)(-1)} }{2(4)}=\frac{-5+/-\sqrt{25+17} }{8)}

\frac{-5+/-\sqrt{42} }{8}

Answer: OPTION B

Step-by-step explanation:

Find (2.2 x 107)(5 x 108) (2.5 x 103)(8.8 x 105) expressed in scientific notation.
jarptica [38.1K]

Answer:

Scientific notation of the multiplication is 2.42\times 10^{25}

Step-by-step explanation:

(2.2\times 10^{7})(5\times 10^{8})(2.5\times 10^{3})(8.8\times 10^{5} )

= (2.2\times 5\times 2.5\times 8.8)10^{(7+8+3+5)}

[Since 10^{a}\times 10^{b}=10^{(a+b)}]

= 242\times 10^{23}

= 2.42\times 10^{25}

Therefore, the scientific notation of the multiplication is 2.42\times 10^{25}
