Which polynomials are in standard form?

igor_vitrenko [27]

Answer:

Choice D.

None of the above.

Step-by-step explanation:

Standard form of polynomial is written as variable power in a decreasing order as shown below.

$ax^{n}+ bx^{(n-1)} +cx^{(n-2)}+............+x^{0}$

Here the power of x is decreasing from n to 0

So,

5-2x can be written as

$-2x^{1} +5x^{0}$

x^4-8x^2-16 can be written as

$x^{4}+0x^{3}-8x^{2} +0x^{1}-16x^{0}$

5x^3+4x^4-3x+1 can be written as

$4x^{4} +5x^{3}+0x^{2}+3x^{1} + 1x^{0}$

Note: $x^{0} =1$

The distance from New York City to Los Angeles is 4090 kilometers. a. [3 pts]What is the distance in miles? (You must use unit f

sergejj [24]

Answer: a) 2556.25 miles

b) 82.5 gallons

Step-by-step explanation:

Given : The distance from New York City to Los Angeles is 4090 kilometers.

$=4090\times\dfrac{5}{8}=2556.25\text{ miles}$ [∵ 1 km= $\dfrac{5}{8}$ miles]

Hence, the distance in miles= 2556.25

If your car averages 31 miles per gallon, then the number of gallons of gas required to use driving from New York to Los Angeles = $\dfrac{\text{Distance}}{31}$

$=\dfrac{2556.25}{31}=82.4596774194\approx82.5\text{gallons}$

Hence, the required number of gallons = 82.5 gallons
