Answer:

{x| 43 ≤ x ≤ 47} where x = Sean's speed (in mph)

Step-by-step explanation:

Sean is taking driver's ed. The instructor asked him to stay within 2 miles of the posted speed limits. The current speed limit is 45 mph.

So, the maximum speed which Sean can reach is, (45 + 2) mph

                                                                                   =47 mph

and,  the minimum speed which Sean can reach is, (45 - 2) mph

                                                                                   =43 mph

so, {x| 43 ≤ x ≤ 47} where x = Sean's speed (in mph)

denis-greek [22]
100% = 1.00 is the cost of the jeans itself
6% = 0.06 is the sales tax to be added
let "cost of jeans" be represented by x
so you will get an expression
(1.00 + 0.06) x + 8.95 = Total Cost

Given:

The limit problem is:

\lim_{x\to 3}(x^2+8x-2)

To find:

The limit of the function by using direct substitution.

Solution:

We have,

\lim_{x\to 3}(x^2+8x-2)

Applying limit, we get

\lim_{x\to 3}(x^2+8x-2)=(3)^2+8(3)-2

\lim_{x\to 3}(x^2+8x-2)=9+24-2

\lim_{x\to 3}(x^2+8x-2)=33-2

\lim_{x\to 3}(x^2+8x-2)=31

Therefore, the correct option is D.
