Step-by-step explanation:
6−2+12
=4+12
=16
18(2+x) because 18*2=36 and 18*x=18x
Answer:
11 seconds
Step-by-step explanation:
If the height h(t) of the sunglasses after t seconds is given by the polynomial function
h(t)=-16t²+1936
The sunglasses will hit the ground when the height h(t)=0
h(t)=-16t²+1936=0
-16t²+1936=0
-16t²=-1936
t²=1936/16=121
t=√121=11 seconds
The Sunglasses will hit the ground 11 seconds after it is dropped by the pilot.
Answer:
no
Step-by-step explanation:
If x = 3 is a zero, then f(3) = 0
f(3)
= 4
- 3³ - 52(3)² - 35(3) + 12
= 324 - 27 - 468 - 105 + 12
= - 264
Since f(3) ≠ 0 then x = 3 is not a zero of f(x)
