Given f(x) = 5x^4 – x^2 + 6x – 1. What is Limit of f (x) as x approaches negative 1?

-3.

Step-by-step explanation:

Substitute x = -1 into the expression.

5(-1)^4 - (-1)^2 + 6(-1) - 1

=5 - 1 - 6 - 1

= 5 - 8

= -3.

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
