Based on the scatterplot of the transformed data and the residual plot, which type of model is appropriate for estimating print publication each year? A linear model is appropriate because the residual plot does not show a clear pattern. A power model is appropriate because the scatterplot of years and the log of circulation is roughly linear. An exponential model is appropriate because the scatterplot of years and the log of circulation is roughly linear and the residual plot shows no distinct pattern. Both an exponential and a power model would be appropriate because the log of circulation was used to develop the model.

A bicycle is traveling at 20 miles per hour. How many feet will it cover in 30 seconds? Round your answer to the nearest tenth of a foot.

Answers

Answer:

$Distance = 880ft$

Step-by-step explanation:

Given

$Speed = 20(miles)/(hour)$

$Time = 30\ seconds$

Required

Determine the distance

To answer this question, we make use of speed-distance relationship

$Speed = (Distance)/(Time)$

Make Distance the subject

$Distance = Speed * Time$

$Distance = 20 miles/hour * 30 seconds$

Convert seconds to hour

$Distance = 20 miles/hour * (30)/(3600) hour$

$Distance = 20 miles * (30)/(3600)$

$Distance = (20 miles * 30)/(3600)$

$Distance = (600\ miles)/(3600)$

$Distance = (1)/(6) miles$

Convert to foot

$Distance = (1)/(6) * 5280\ ft$

$Distance = (1* 5280\ ft)/(6)$

$Distance = (5280\ ft)/(6)$

$Distance = 880ft$

Answer:

y" = -24 / y³

Step-by-step explanation:

6x² + y² = 4

Take the derivative of both sides with respect to x.

12x + 2y y' = 0

Again, take the derivative of both sides with respect to x.

12 + 2y y" + y' (2y') = 0

12 + 2y y" + 2(y')² = 0

Solve for y' in the first equation.

2y y' = -12x

y' = -6x/y

Substitute and solve for y":

12 + 2y y" + 2(-6x/y)² = 0

12 + 2y y" + 2(36x²/y²) = 0

12 + 2y y" + 72x²/y² = 0

6y² + y³ y" + 36x² = 0

y³ y" = -36x² − 6y²

y" = (-36x² − 6y²) / y³

Solve for y² in the original equation and substitute:

y² = 4 − 6x²

y" = (-36x² − 6(4 − 6x²)) / y³

y" = (-36x² − 24 + 36x²) / y³

y" = -24 / y³
