Answer:
42
Step-by-step explanation:
<span>There are several ways to find the max of min of a quadratic equation.
Max occurs when t = -b/2a
t = -b/2a = -68/(2*-4.9) = 6.93 second
Max altitude = h(6.93) = 68(6.93)-4.9(6.93^2) = 235.92 meters

Answer:

Step-by-step explanation:
This limit can be written as follows

Direct substitution means that we substitute in the value for x to get our limit

Answer:
196 inches.
Step-by-step explanation:
We have been given that an ant can travel at a constant speed of 980 inches in every 5 minutes.
To find the distance traveled by ant in one minute we will divide total distance traveled by time taken to travel that distance.


Therefore, ant travels 196 inches in one minute.
(1/2) * x^3 + 3.4y when X = 2 and Y = 5.
= (1/2) * (2^3) * 3.4(5)
= (1/2) * 8 * 17
= (1/2) * 136
= 136/2
= 68.
