Answer:
(a) t = 7 sec approximately; (b) t = 6 sec
Step-by-step explanation:
(a) Set h(t)= -16(t-3)^2 + 288 = 0 and solve for t:
16(t-3)^2 = 288
After simplification, this becomes (t - 3)^2 = 18, or t - 3 = ±3√2.
Because t can be only zero or positive, t = 3 + 3√2 = 7 seconds
(b) Solve h(t)= -16(t-3)^2 + 288 = 150:
-16(t-3)^2 = - 162
or (t - 3)^2 = 10.125, or
t - 3 = ±3.18, or, finally, t = 6.18 sec (discard t = -0.18 sec)
The convert of TT$1 020.00 to US$150.
Given that,
- US $1.00 should be equivalent to the TT $6.80.
- Now we have to convert TT $1,020 to US $.
So, the value after converting should come
= $1,020 ÷ $6.80
= $150
Therefore we can conclude that the convert of TT$1 020.00 to US$150.
