Answer: 4x² -4
Step-by-step explanation:
First, evaluate the exponent you'll get,
+ 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms, -4 +4x² turns into, 4x² -4!
Answer:
Step-by-step explanation:
According to the table, function g(x) reaches the max height of 33, approx.
The equation of motion is f(x) = -16x^2 + 42x + 12. We need to determine the maximum of this function. To do this, find the x-coordinate of the vertex, which is x = -b/(2a), or x = -42/(2*-16), or 1.31 sec.
Evaluating f(x) = -16x^2 + 42x + 12 at x = 1.31 sec, we get f(1.31) = 39.6.
So it appears that f(x) has a higher max than does g(x); the difference is approx. 39.6 - 33, or 6.6
Answer:

Answer:
-199
Step-by-step explanation:
- put -6 in place of x in equation
The correct answer here is that if the skydiver is falling 176 feet per
second, he is falling 10560 feet per minute. This can be worked out
quite easily, by considering that if there are 60 seconds in a minute,
we then need to work out the proportion of 176 feet/1 sec = x/60 sec.
You then need to multiply 60 by 176 to get 10560, which is your answer.
