The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is
-16(0)^2 + 144 = 144ft
Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).
-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3
The domain is 0 to 3 seconds.
We are given that the titanic is found 3,797 m below sea level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one decimal.
We should take note that the letter k in km means kilo and a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000 m. So to convert, simply multiply a value with unit m with this conversion factor. Conversion factor = 1 km / 1000 m
Depth of titanic = 3,797 m (1 km / 1000 m)
Depth of titanic = 3.797 km = 3.8 km
Answer:
your answer is 24m n hope this helps
Step-by-step explanation:
Answer:
1) m<2 = 115°
2) m<5 = 83°
3) m<8 = 45°
4) m<4 = 137°
Step-by-step explanation:
When two lines cross over each other, creating four angles, the opposite angles are equal.
So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.
Similarly, in question two, <5 = <6 = 84°.
In question three, <8 = <9 = 45°.
and in question four, <3 = <4 =137°.
Answer:
54 students
Step-by-step explanation:
331 - 7 = 324
324 divided by 6 = 54
