A ball is thrown into the air at an initial velocity of 18 meters per second from an initial height of 10 meters. The equation that models the path of the ball is given by h = - 4.9t ^ 2 + 18t + 10 . When does the ball reach its maximum height ?

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group

false

inverse variation is not exponential

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2
