The best way to do this is to set up a proportion
2 5
--- = ----
5 x
then cross multiply and divide
5 times 5=25/2=12.5
he would move 12.5 feet in 5 hours
I hope I've helped!
Answer:
$330
Step-by-step explanation:
You time 15 by each squat ft
1) The graph consists of three horizontal segments, with discontinuities (jumps) at x = 1, x = 2, and x = 3.
A horizontal segment at y = - 2 for the values x = 0 to 1.
A horizontal segment at y = - 1 for values x = 1 to 2
A horizontal segment at y = 0 for values x - 2 to 3.
2) To know whether the end points of a segment are defined by the left or the right values you have to look for the circle at the extreme of the segment: if it is a solid dot, means that the end is included, if is is an open circle (white inside) then the end is not included in that segment.
3) That function is based on the function named integer part because if relates y with the integer part of x.
The integer value function is [x] and it makes correspond y values witht he integer values of x.:
y = 0 witht the integer value of x for x between 0 and 1, excluding 1.
y = 1 with the integer value of x between 1 and 2 (excluding 2)
y = 2 with the integer value of x between 2 and 3 (excluding 3)
y = 3 with the integer value of x between 3 and 4 (excluding 4)
But our function is two units below, so it is [x] - 2
Answer: -6 - 5k
Step-by-step explanation:
-3(2+4k) +7(2k-1)
-6+(-12k) + 14k -7k
-6 -12k + 14k - 7k
-6 -5k
Answer:
t = 1.143 s
Step-by-step explanation:
The equation he uses to model the height of the rocket in cm, as function of time is
h(t) = -490 t^2 + 1120t
We can plot this equation using a graphing tool
Please, see attached picture
The rocket reaches his maximum height (640 cm) at
t = 1.143 s
