Answer:
After 2 seconds
Step-by-step explanation:
First step is find an equation of velocity:
h(t)=-16t2+64t+112. The velocity function is derivated from position function, so we should do that.
v(t)= h´(t)= -16*2*t+64 ⇒ v(t)= -32t+64.
Now we know the arrow reach the maximun height when this velocity is equal to zero when t>0.
0=-32t+64 ⇒ 32t=64, split each member for 32 ⇒ =
t=2. That means after 2 sec. the arrow reach the maximum height
0.41567 is:
... rational because it can be expressed as a fraction (e.g., 41567/100000)
... not irrational for the same reason
... not whole (obviously)
... not integer (obviously)
Answer:
1/3
Step-by-step explanation:
For each term multiply each number to see what value you get, only 1/3 makes sense
18 x 1/3 =6
6 x 1/3= 2
Answer:
4 buses
Step-by-step explanation:
There are 173 basketball fans
one bus can hold 46 fans
Hence the number of buses needed can be calculated as follows
= 173/46
= 3.76
= 4
Hence 4 buses are needed
