A rock is thrown upward from a bridge that is 57 feet above a road. The rock reaches its maximum height above the road 0.76 seco
bekas [8.4K]

answer:

f(t) = -9.9788169(t -0.76)^2 +57

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 f(x)= a(x-p)^2 +q  , where (p,q) is the turning point. now we substitute the turning point

f(t) = a(t-0.76)^2 + 57, 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

f(t) = -9.9788169(t-0.76)^2 +57

An online shopping club has 12,500 members when it charges $8 per month for membership. For each $1 monthly increase in membersh
-BARSIC- [3]

Answer:

Revenue  =  Members  *  (Cost Per Member)

R  = (12.500 *8) =

R= 100.000

R  = (12.500 - 500) ( 8 + 1)=

R=12000*9=

R=108.000

Step-by-step explanation:

Revenue  =  Members  *  (Cost Per Member)

R  = (12.500 *8) =

R= 100.000

R  = (12.500 - 500) ( 8 + 1)=

R=12000*9=

R=108.000

 

Where x represents the number of $1  increases

Where x represents the number of $1  increases
