X can not = 0 because if I did your answer would not be a fraction it would be 0
Answer:
I think
"Quadriplegia" would go with a "spinal cord injury".
Quadriplegia is a spinal cord injury that causes you to lose feelings in all four limbs.
A "knee injury" would go with "Limited ability to walk and run."
"Headaches" with "traumatic brain injury."
Hope this helps!
Answer:
The expression that represents his total time is given by "t = 7.5/s" where s is his speed against the wind.
Step-by-step explanation:
In order to solve this problem we will assign a variable to Curtis speed on the first leg of the trip, this will be called "s". Since the speed on the first part is "s" and the speed on the second part is 20% higher, then the speed on the second part is "1.2s". Each leg of the course is 9 miles long, therefore the time it took to go each way is given by:
time = distance/speed
First part:
t1 = 9/s
Second part:
t2 = 9/1.2s = 7.5/s
The expression for the whole course is the sum of each, so we have:
t = t1 + t2
t = 9/s + 7.5/s
t = (9 + 7.5)/s = (16.5)/s
The domain of a function is the complete set of possible values of the independent variable. In this case, the independent variable is any nonnegative integer. The nonnegative integers are the set of positive integers along with zero, then,
domain = {0, 1, 2, 3, ...} = natural numbers.
