Answer:
18,223 feet
Step-by-step explanation:
y= -16t^2 + 608t + 12,447.
y = -16(t² - 38t) + 12447
y = -16[t² - 2(t)(19) + 19² - 19²] + 12447
y = -16(t - 19)² - 16(-19²) + 12447
y = -16(t - 19)² + 18223
Vertex: (19, 18223)
Max height is 18,223 at t = 19
Answer:
The required sequence is . The average rate of change from n = 1 to n = 3 is -7.5.
Step-by-step explanation:
From the given graph it is clear that the sequence is a GP because the all terms are half of their previous terms.
Here,
The common ratio of GP is 1/2.
The first term of the sequence is 20.
The formula for sequence is
Where a is first term and r is common difference.
The required sequence is
The formula for rate of change is
The average rate of change from n = 1 to n = 3 is
Therefore the required sequence is . The average rate of change from n = 1 to n = 3 is -7.5.

Step-by-step explanation:
Quadratic formula using Lin's theory.
Answer:
{x | x R, x ≤ -4}
Step-by-step explanation:
Given choices are:
{x | x R, x < -4} {x | x R, x ≤ -4} {x | x R, x > -4} {x | x R, x ≥ -4}
Now we need to find about Which of the following sets would have a graph that is a closed circle on -4 and an arrow to the left?
we know that close circle is used only if we have ≤ or ≥ in given inequality.
Since arrow goes to the left then it must be ≤
Hence final answer is {x | x R, x ≤ -4}
For this case, it depends on the context of the problem.
Most of the times the negative numbers in these types of problems mean that we owe money to some person or bank.
For example, if a car costs $ 2000 and I have $ 1500 available, then I must ask for a loan at the bank:
It means that I have to pay $ 500 to the bank.
Answer:
Amount of money you must pay.
