Step-by-step explanation:
Answer:
17/18 and 1/4 is the answer
Answer:
3072ft
Step-by-step explanation:
we have,
h(t)=-16t²+192t+2560
where
h -----> is the height in feet of the rock
t -----> the time in seconds
For t=8 seconds
substitute the value of t in the function and find the value of h
h(8)=-16(8)²+192(8)+2560
=3072ft

cosine ( CAH) = Adjacent/ hypothenus
cos9 = x/ 2
let x represent the horizontal distance
2 cos 9 = x
x = 2 (0.98768834)
x = 1.975
x = 1.97
therefore the horizontal dstance jade covers is 1.97km
If Sin 60 = √3 / 2
Then, Cos 60 = ?
Well, we know :
Sin^2x + Cos^2x = 1
Let X = 60°
That is,
Sin^2(60) + Cos^2(60) = 1
(√3 / 2)^2 + Cos^2(60) = 1
3 / 4 + Cos^2(60) = 1
Cos^2(60) = 1 - 3/4
Cos^2(60) = 4/4 - 3/4
Cos^2(60) = (4-3)/4
Cos^2(60) = 1/4
Cos(60) = √(1/4)
Cos(60) = √1 / √4
Cos(60) = 1 / 2
This's answer right to the your question.
