Question 1054548: <span>An oil tanker with engine trouble radios the mainland for a seagoing tugboat. At the time that the tugboat leaves the dock, the tanker is 125 km away and heading directly toward the dock. If the average speed of the tugboat is 20 km/h and that of the tanker is 5 km/h how long will it take the two vessels to meet? </span>

Question 1054451: <span>two cars are traveling down the highway with the same speed. If the first car increases its speed by 10 kilometers per hour, and the other car decreases its speed by 10 kilometers per hour, then the first car will cover the same distance for 2 hours as the second car for 3 hours. what is the speed of the cars? </span>
<span>A</span><span>two cars are traveling down the highway with the same speed.
If the first car increases its speed by 10 kilometers per hour, and the other car decreases its speed by 10 kilometers per hour, then the first car will cover the same distance for 2 hours as the second car for 3 hours.
what is the speed of the cars?
:
let s = the original speed
Write a distance equation; dist = time * speed
3(s-10) = 2(s+10)
3s - 30 = 2s + 20
3s - 2s = 20 + 30
s = 50 km/hr is the original speed
:
:
confirm this, find the distances
3(50-10) = 120 km
2(50+10) = 120 km

(3x-2)(x2+x+6) this is impossible srry
It must have the same slope as the given line, so
m = -A/B = -1/-2 = 1/2
So far, we have
y = mx + b = x/2 + b
Use the given point to find b.
4 = -2/2 + b = -1 + b
b = 5
y = x/2 + 5
Multiply through by 2.
2y = x + 10
Standard form:
x - 2y = -10
Answer:
The constant polynomial whose coefficients are all equal to 0. The corresponding polynomial function is the constant function with value 0, also called the zero map. The zero polynomial is the additive identity of the additive group of polynomials. ... In the Wolfram Language, Exponent[0, x] returns -Infinity.
<u>It has no nonzero terms, and so, strictly speaking, it has no degree either.</u>
