Answer:
the correct answer is ....
Answer:
0.5 seconds
Step-by-step explanation:
Equation: h(t) = -5t²+5t=10
Where h(t) is in meter, t is in seconds.
The driver will reach maximum height when d[h(t)]/d(t) = 0
From the equation,
d[h(t)]/d(t) = -10t+5
Therefore,
-10t+5 = 0
Solve for t
-10t = -5
10t = 5
t = 5/10
t = 0.5 seconds.
Hence the height will be maximum in 0.5 seconds.
Answer:
Yes, the given relation is a function.
Step-by-step explanation:
Given the quadratic function, y = (x + 1)², and the domain of {-2, -1, 0, 1, 2, 3}:
By definition, a function is a <em>relation</em> in which no two ordered pairs have the same first component (x-values) and different second components (y-values). Observing the given domain, there are no repeating <em>input</em> values.
Therefore, the correct answer is that the relation is a function.
Answer:
Up to 5 hours
Step-by-step explanation:
<u>Given:</u>
- One off fee = $46
- Hourly rent = $6.4 / hr
- Amount limitation= $78
<u>Equation to reflect the condition:</u>
- 78 = 46 + 6.4t
- 6.4t = 78 - 46
- 6.4t = 32
- t = 32/6.4
- t = 5 hours max
So, the meeting room can be rented for up to 5 hours with $78
