Answer:
68 feet
Step-by-step explanation:
Gina uses the function to model the height of a kite based on the amount of string released when the kite is flown:
k(h) = 4h − 12
Where
h represents the height of the kite in feet
k(h) represents the amount of string released in feet.
We need to find the height when Gina released 20 feet of string.
Put h = 20 in the above formula.
k(20) = 4(20) − 12
= 68 feet
So, the required height is 68 feet.
The answer to this is |x| = 4
I think it is 26.18. Hope this helps. :)
Answer: -22 degrees
Step-by-step explanation:
Answer: Between x = -2 and 0.
Explanation: Let's first look for an interval where the gradient is decreasing. That is, if we were given the function for each curvature or line, the derivative would be negative.
We see that only two places have a decreasing gradient (between 0 and -2 and 2 and 4).
Now, the question asks for a non linear line. So, we want to look for a curve instead of a line and thus, the only viable interval is between -2 and 0.
