A quantity with an initial value of 6500 decays exponentially at a rate of 45%
Allisa [31]

1081.44 is the value of the quantity after 0.1 hours, to the nearest hundredth.

What Is percent in simple words?

  • Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.
  • Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent.
  • You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.

Based on the given conditions, formulate = 6500 *  (1 - \frac{45}{100} )^{( 0.1 * 60/2)}

Evaluate the equation/expression=  1081.4375

Round the number: 1081.44

Therefore, 1081.44 is the value of the quantity after 0.1 hours, to the nearest hundredth.

Find an explicit solution to the Bernoulli equation. y'-1/3 y = 1/3 xe^xln(x)y^-2
NNADVOKAT [17]

y'-\dfrac13y=\dfrac13xe^x\ln x\,y^{-2}

Divide both sides by \dfrac13y^{-2}(x):

3y^2y'-y^3=xe^x\ln x

Substitute v(x)=y(x)^3, so that v'(x)=3y(x)^2y'(x).

v'-v=xe^x\ln x

Multiply both sides by e^{-x}:

e^{-x}v'-e^{-x}v=x\ln x

The left side can be condensed into the derivative of a product.

(e^{-x}v)'=x\ln x

Integrate both sides to get

e^{-x}v=\dfrac12x^2\ln x-\dfrac14x^2+C

Solve for v(x):

v=\dfrac12x^2e^x\ln x-\dfrac14x^2e^x+Ce^x

Solve for y(x):

y^3=\dfrac12x^2e^x\ln x-\dfrac14x^2e^x+Ce^x

\implies\boxed{y(x)=\sqrt[3]{\dfrac14x^2e^x(2\ln x-1)+Ce^x}}

If your going 80 miles per hour how much time would it take you to go 80 miles?
Anika [276]
This should be pretty self explanatory. "miles per hour" is how many miles you can drive in 60 minutes. So, it would take....an hour to reach 80 miles. You're going 80 miles per hour.
