Find the rate of change in the table​
mixas84 [53]

Answer:

I'm pretty sure it's +(-6).

Step-by-step explanation:

Basically for these, you find the slope. The slope equation is y1-y2/x1-x2.

Pick two points.

I'll just do (1,15) and (2,9).

15-9/1-2 = 6/-1 = -6.

I don't know if you were taught it this way, but my math teacher always told us that the rate of change had to be positive.

So you'd say the rate of change is +(-6), not -6.

Hope that sorta helped lol

(100+ POINTS)
horsena [70]

Answer:

1) 102.7 meters

2) 11

Step-by-step explanation:

1) -4.9x² + 75x = -4.9x² + 50x + 38

25x = 38

x = 1.52 s

Height = -4.9(1.52)² + 75(1.52) = 102.67904 m = 102.7 m

2) f(x) = x² + 3x - 2

f(2) = 2² + 3(2) - 2 = 8

f(6) = 6² + 3(6) - 2 = 52

Average rate of change:

(52-8)/(6-2) = 11

Please help !! what’s the answer? i don’t understand !!
dedylja [7]

Answer:

992

Step-by-step explanation:

You must convert the meter the kilometer by miltiplying by 1000

and when you do it you must multiply 0.992 by 1000 since it is a fraction .

or you can work it this way :

  • 0.992⇒1m
  • x(the new rate) ⇒1000m
  • x= 0.992*1000= 992
