Simplify (x^3-x+1)/( √(x) )

Answers

Divide each term by √(x) to get x^(2) √(x) - √(x) + ( √(x) )/(x)
(x^(3) - x + 1)/(√(x)) = (x^(3) - x + 1)/(√(x)) * (√(x))/(√(x)) = ((x^(3) - x + 1)√(x))/(x) = (x^(3)√(x) - x√(x) + √(x))/(x) = x^(2)√(x) - √(x) + (√(x))/(x)

Trina finds a car at a dealer for $6,100 The suggested retail price in the car price guide is $6,300. What is the difference between these two prices? Should Trina buy the car? Explain.

Answers

The linear function y = 1.2x represents Alberto’s speed, y, in meters per minute, when his stride rate is x steps per minute.Explain what the slope and y-intercept of the linear model represent in the context of the situation.

Answers

Answer with explanation:

The linear function is given by:

              y=1.2x

where y represents Alberto's speed in meters per minutes.

when his stride rate is x steps per minute.

We know that for any linear function of the type:

  y=mx+c

m represents the slope and c represents the y-intercept of the function.

  • Here m=1.2 and c=0

i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.

  • and the y-intercept represents the speed of Alberto when he took 0 steps i.e when x=0.

It represents that his speed is 0 meter per minutes when he did not took any step.
The slope is the rate in which he is moving and the y-intercept is where he started (at 0 seconds and 0 meters).

Answer:

To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
