The height of a ball can be estimated by the following equation h(t) = 8t^2 4t 125 where t is time, in seconds, after the ball was thrown and h(t) is the corresponding height, in meters. what is the height at t=2.3 seconds

Replace t with 2.3 and solve:

8(2.3)^2 +4(2.3) + 125

Simplify:

8(5.29) + 9.2 + 125

42.32 + 9.2 + 125

51.52 + 125

176.52 meters

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
