Answer:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference.

Step-by-step explanation:
I like to work problems involving repetitive calculations using a spreadsheet. The sort function can easily put the results in the appropriate order.
__
Here, we need to compute minutes and kilometers remaining for each cyclist, and then divide the former by the latter to find the required timing.
Minutes remaining will be the difference between the qualifying time and the time used so far.
Km remaining will be the difference between the race length and the distance traveled so far.
Required minutes per km will be the ratio of minutes remaining to km remaining.
Levi has the least allowed minutes per km for his remaining distance. Roberto has the most.
_____
Christopher only has to increase his average speed by about 5% in order to qualify; Levi has the greatest challenge, as he needs about 18% more speed for the rest of the race.
Solution for the question asked: 3x^2-5x+4=6
it can be simplified by subtracting 6 from both the sides...
3x^2-5x+4-6=6-6
3x^2-5x-2=0 which is the required form where a=3,b=-5 and c=-2.Now putting the values in the formula we will get two values for x which are 6 and (-1).
hope this will help you
Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).
That angle ladder makes with the ground = €
SOH: sin € = opposite/hypotenuse
No the ladder won't be safe!!!
Now let's make it safe:
The ladder's length (w) is constant, so stays 12
So now let's ask in an inequality what height will be safe (75° or less)
what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!
Hope that helps! :-D
