<span>The answer is simple: between 5 and 6. The way you find this is you take the nearest perfect square less than 35 and greater than 35. The nearest perfect square less than 35 is 25 and the nearest perfect square greater than 35 is 36. The square roots of both are respectively 5 and 6. Therefore, the square root of 35 must lie between 5 and 6.

Answer:
option D would be your answer
Step-by-step explanation:

The piecewise function for this should be
.
We can find the first equation simply. He gets 20 every hour up to 42 hours. Therefore, the function gives us our first equation of y = 20x when x < 42.
The second one, we must know what the base amount he would make before starting to make 28 an hour. The 28 an hour would be 28x, but he would have already made 840 before hand. Which we can determine by multiplying the base of 42 hrs by 20.
42 * 20 = 840.
I'm pretty sure you already solved this by now, but I'll say the answer anyway. This problem has already been solved by another as a verified answer.
This is the concept of financial algebra, we are required to calculate the value of stock ABC which follows the model given by:
y=12.21x+37.42
given that x=62 days,
the value of th estock after 62 days will be given by:
y=12.21(62)+37.42
y=757.02+37.42
y=794.44
ABC will be worth $794.44
