Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
Answer:
12
Step-by-step explanation:
since 1 inch equals 2.54 cm then 11 inches equals 27.94 cm
27.94 ÷ 2.33 = 11.99
Answer:
x<32 (i thik is what you want)
Step-by-step explanation:
if x/8+1<3
x has to be less the 4*8, which is 32.
so x<32
Answer:
857.96
Step-by-step explanation:
964/100=9.64
9.64x11=106.04
964-106.04=857.96
These intervals are measured by the x-values. Additionally, intervals of increase and decrease are always express with parentheses in interval notation. Therefore, the decreasing interval is (-2, 0)U(1, 3) and the increasing interval is (0, 1).
Hope this helps!
