Answer:
y = -2x + 8 is the answer to the question
-x^5 - x^2+ 9
Here’s your answer
Answer:
=1.283 , 0.779 seconds
Step-by-step explanation:
h=2+33t-16t²
when h=18 ft
then18=2+33t-16t²
→ 16t²−33t+16=0
t= [−(−33)±√{(−33) ²−4×16×16)}]/(2×16)
= [33±√{1089−1024}]/(32)
= [33±√{65}]/(32)
=1.283 , 0.779 seconds
