Help Please !! The trajectory of a potato launched from a potato cannon on the ground at an angle of 60 degrees with an initial speed of 50 meters per second can be modeled by the parabola:
f(x) = 1.73x-0.0078x, where the x-axis is the ground. Find the height of the highest point of the trajectory and the horizontal distance the potato travels before
hitting the ground.

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
