The height, in meters, above sea level of a NASA launched rocket it given by h(t)=−4.9t2+103t+353 where t represents the number of seconds since the rocket was launched. (Round your answer to 3 decimal places as needed for both answers.) Can someone show me how to solve this problem? Pls

Assuming that the rocket will splash down into the ocean, after how many seconds will the splashdown occur?

How many meters above sea level does the rocket get at its peak?

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

make sure you have version 2.50

try looking in the very back of the book : )
