What is the equation of a line that passes through the point (2, 7) and is perpendicular to the line whose equation is y=x4+5 ? enter your answer in the box.

Step-by-step explanation:

We are given that an equation

We have to find the equation of a line that passes through the point (2,7) and perpendicular to given line.

Differentiate w.r.t x

Using:

When two lines are perpendicular then

Slope of a line=

Slope of perpendicular line=

The equation of  a line passing through the point (

with slope m is given by

Using this formula

The equation of perpendicular line with slope -4 and passing through the point (2,7) is given by

Hence,the equation of the line which is passing through the point (2,7) and perpendicular to the given line is given by

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
