Answer:
=102
Step-by-step explanation:
17=1/6 of the price
x=1/1 of the price
x=1*17*6=102
The equation is s=144t - 16t², s being the distance and V=144 ft/s
a)The maximum (or minimum) is reached when the derivative of s = 0
s' = 144 - 32t = 0 and t= 9/2 or 4.5 second (time needed to reach the max
Now plug t= 4.5 in the original equation and you will find s = 324 ft
(Why it's a max and not a minimum: because 2nd derivative is negative and equals s" = -32)
b) Velocity of the ball: distance (up) s=320 ft, time that means:
320 =144t - 16t² (solve for x) -16t²+144t-320 = 0, t₁ =4 and t₂ =5 (t₂ is not valid since max time to reach summit is 4.5) so t =4s , distance = 320. so the velocity at 320ft is 320/4 = 80 ft/s
c) Due to the symmetry of the parabola, the velocity at 320 ft on its way down = 80 ft/s
Answer:
The untouched space in the basement is the upper 2.2 meters.
Step-by-step explanation:
An inequality<span> is a sentence with <, >, ≤, or ≥ as its verb. An example is 3x - 5 < 6 - 2x. To </span>solve<span> an inequality is to find all values of the variable that make the inequality true. Each of these numbers is a solution of the inequality, and the set of all such solutions is its </span>solution set<span>. Inequalities that have the same solution set are called equivalent inequalities.</span>
