a penguin leaps out of the water while swimming. The height y (in feet) of a proposing penguin can be modeled by y= -16x2 + 20x where x is the time (in seconds) since the penguin leaps out of the water. find the root of the equation when y = 0

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.

idk

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169
