Answer:

See below

Step-by-step explanation:

The question is missing information:  " . . . how far would he go in an <u>???"</u>

<u></u>

If the question is how far he would go in a [Pick a despised car model} ?  The answer is still 400.  The car would break down.

If the question is how far would he go in the same amount of time:

Whe the speed limit was 55, it would take Bob (55 miles/hr)*(X hr) = 400 miles

X = 7.273 hours to go 400 miles at 55 mph.

Identify the leading coefficient in the following polynomial:<br> 10x2 + 3x – 5
Alisiya [41]

Answer:

The leading coefficient in the polynomial 10x2 + 3x - 5 is 10.

Step-by-step explanation:

To find the leading coefficient of the polynomial function, we must first locate the leading term. In a polynomial function, the leading term is the term containing the highest power of x. In this polynomial function, the leading term is 10x2. The leading coefficient of a polynomial function is the coefficient of the leading term, and so the leading coefficient of this polynomial function is 10.
