Answer:
20 seconds
Step-by-step explanation:
Your friend starts 10 meters in front of the starting line.
You start from the starting line.
You run at 6 meters/ second.
Your friend runs at 5.5 meters/second.
You and your friend will be at the same distance from the starting line only when you are able to catch your friend.
The relative speed between you two is the difference in your speed and your friend's speed that is:
So to cover 10 meters of separation at the speed of 0.5 meter/second it will take:
So it will take 20 seconds for you and your friend to be at the same distance from the starting line.

Answer: Domain of the given function is all real numbers.
Range of the given function is {y | y>=1}
Step-by-step explanation:
The given function is a polynomial and the domain of any polynomial is all the real numbers because for any value of x, the function will have some value.
Hence, the domain will be all real numbers.
Range is the set of y values for which the function is defined.
This is a polynomial and to find the range, we will simplify the polynomial.
Therefore, for any value of x, f(x) ≥ 1
Hence, the range becomes {y | y ≥ 1}
Answer:
graetest 9876 smallest 1273
Step-by-step explanation:
The rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. I'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
