Look at the table to answer the question.
Alexus [3.1K]

Answer:

Your power function is  y=-2x^{2}

Step-by-step explanation:

The way I found it was.

0=0,  so, the function multiply by zero, and have no other term to add

A number (one in a case) gives as a result: -2.  So, one, elevated to ANY power results in one, every time. So, I have 1, as a factor and -2 as a result. One is as well a factor that delivers a result equal to the other factor. (3)(1)=3 , (8987)(1)=8987. So, the other factor must be -2

Then I checked all the table, and the results were consistent.

If you have 6 lessons a week in mathematics, each lesson being 38 minutes long, what is the total time spent in mathematics less
Lynna [10]

Answer:

2280 minutes.

Step-by-step explanation:

Time spent each week in lessons = (Lessons per week)(Time per lesson)

= (6)(38)

= 228 minutes/week

Time spent in a 10-week period:

10 weeks * 228 minutes/week

= 2280 minutes

Use conversion factors to determine the time in the desired units (i.e. Hours, seconds, etc.).

Hope this helps!
