Answer: C. The drone is on the ground at 0 and 4 seconds.
Step-by-step explanation:
Here the function that shows the height of the drone,
Where t is the time in seconds.
Since, the drone is ground when, h(t) = 0
(by subtracting 64 from both sides 64)
(dividing both sides by -16 )
(by subtracting 4 from both sides)
⇒ t = 0 or t = 4
Thus, Option C is correct.
180 degrees counterclockwise
Answer:
For an equation like:
y = a*x + b
a is the slope, and this is the rate of change of the function.
For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.
Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.
Answer: 75,83
Step-by-step explanation: add by 8 to every number
I would say that the "n"th term of the sequence is 41, as the pattern increases by 10 every term.
