answer:

Step-by-step explanation:
On this question we see that we are given two points on a certain graph that has a maximum point at 57 feet and in 0.76 seconds after it is thrown, we know can say this point is a turning point of a graph of the rock that is thrown as we are told that the function f determines the rocks height above the road (in feet) in terms of the number of seconds t since the rock was thrown therefore this turning point coordinate can be written as (0.76, 57) as we are told the height represents y and x is represented by time in seconds. We are further given another point on the graph where the height is now 0 feet on the road then at this point its after 3.15 seconds in which the rock is thrown in therefore this coordinate is (3.15,0).
now we know if a rock is thrown it moves in a shape of a parabola which we see this equation is quadratic. Now we will use the turning point equation for a quadratic equation to get a equation for the height which the format is
, where (p,q) is the turning point. now we substitute the turning point
, now we will substitute the other point on the graph or on the function that we found which is (3.15, 0) then solve for a.
0 = a(3.15 - 0.76)^2 + 57
-57 =a(2.39)^2
-57 = a(5.7121)
-57/5.7121 =a
-9.9788169 = a then we substitute a to get the quadratic equation therefore f is

Answer:
294 cubic ft.
Step-by-step explanation:
All you do is just multiply the length, width, and height!
3 × 14 × 7 = 294
hopefully this helped :3
Answer:
715 pounds
Step-by-step explanation:
<em>FV = solve</em>
<em>PV = 600</em>
<em>I% = 6</em>
<em>K = 1, N = 3 </em>(2013 - 2016 = 3 years)
Plug it in:
<em>FV = 600 x [ 1 + (6/100 x 1)]³</em>
= 600 x ( 1 + 0.06)³
= 600 x (1.06)³
FV = 714.61, 715 to the nearest dollar.
<em>Therefore, the fee in 2016 is 715 pounds.</em>

Answer:
18.84 cm
Step-by-step explanation:
P = 2 × pi × r
= 2 × 3.14 × 3cm
= 6cm × 3.14
= 18.84 cm
