\frac{x^{2} + x - 2}{6x^{2} - 3x} = \sqrt{2x} + \frac{3x^{2}}{2}
\frac{x^{2} + 2x - x - 2}{3x(x) - 3x(1)} = \frac{2\sqrt{2x}}{2} + \frac{3x^{2}}{2}
\frac{x(x) + x(2) - 1(x) - 1(2)}{3x(x - 1)} = \frac{2\sqrt{2x} + 3x^{2}}{2}
\frac{x(x + 2) - 1(x + 2)}{3x(2x - 1)} = \frac{2\sqrt{2x} + 3x^{2}}{2}
\frac{(x - 1)(x + 2)}{3x(2x - 1)} = \frac{2\sqrt{2x} + 3x^{2}}{2}
\frac{(x - 1)(x + 2)}{3x(2x - 1)} = \frac{2\sqrt{2x} + 3x^{2}}{2}
3x(2x - 1)(2\sqrt{2x} + 3x^{2}) = 2(x + 2)(x - 1)
3x(2x(2\sqrt{2x} + 3x^{2}) - 1(2\sqrt{2x} + 3x^{2}) = 2(x(x - 1) + 2(x - 1))
3x(2x(2\sqrt{2x}) + 2x(3x^{2}) - 1(2\sqrt{2x}) - 1(3x^{2})) = 2(x(x) - x(1) + 2(x) - 2(1)
3x(4x\sqrt{2x} + 6x^{3} - 2\sqrt{2x} - 3x^{2}) = 2(x^{2} - x + 2x - 2)
3x(4x\sqrt{2x} - 2\sqrt{2x} + 6x^{3} - 3x^{2}) = 2(x^{2} + x - 2)
3x(4x\sqrt{2x}) - 3x(2\sqrt{2x}) + 3x(6x^{3}) - 3x(3x^{2}) = 2(x^{2}) + 2(x) - 2(2)
12x^{2}\sqrt{2x} - 6x\sqrt{2x} + 18x^{4} - 9x^{3} = 2x^{2} + 2x - 4
12x^{2}\sqrt{2x} - 6x\sqrt{2x} = -18x^{4} + 9x^{3} + 2x^{2} + 2x - 4
6x\sqrt{2x}(2x) - 6x\sqrt{2x}(1) = -9x^{3}(2x) - 9x^{3}(-1) + 2(x^{2}) + 2(x) - 2(2)
6x\sqrt{2x}(2x - 1) = -9x^{3}(2x - 1) + 2(x^{2} + x - 2)

Colt1911 [192]
1/4 hour = 4 1/4 miles

Change to improper fraction:
1/4 hour = 17/4 miles

Multiply by 4 on both sides:
1 hour = 17 miles

Answer: Ramon rides his bike at 17 miles/hour.

Suzy deposits $500 in a savings account with an interest rate of 6% compounded annually. if suzy does not make any additional de
Savatey [412]

Answer:

It will take about 3 years for Suzy to earn at least $95.

Step-by-step explanation:

Compound interest is interest computed on the original principal as well as on any accumulated interest.

If you deposit <em>P</em> dollars at rate <em>r</em>, in decimal form, subject to compound interest, then the amount, <em>A</em>, of money in the account after <em>t</em> years is given by

                                                      A=P(1+r)^t

The amount <em>A</em> is called the account's future value and the principal <em>P</em> is called its present value.

From the information given we know that $500 is the present value,  6% is the rate, and we want to find how long will it take for Suzy to earn at least $95, this means when the future value is $595.

Applying the above formula and solving for <em>t </em>we get that:

595=500(1+\frac{6}{100} )^t\\\\500\left(1+\frac{6}{100}\right)^t=595\\\\\left(1+\frac{6}{100}\right)^t=\frac{119}{100}\\\\\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)\\\\\ln \left(\left(1+\frac{6}{100}\right)^t\right)=\ln \left(\frac{119}{100}\right)\\\\\mathrm{Apply\:log\:rule}:\quad \log _a\left(x^b\right)=b\cdot \log _a\left(x\right)\\\\t\ln \left(1+\frac{6}{100}\right)=\ln \left(\frac{119}{100}\right)

t=\frac{\ln \left(\frac{119}{100}\right)}{\ln \left(\frac{53}{50}\right)}\approx 2.99
