Acceleration is simplified by assuming it is the constant -g
a=-g we integrate this with respect to time to get v...
v=-gt+C where C is the initial velocity in this case 14ft/s so
v=-gt+14 integrate again to get the height function
h=(-gt^2)/2 +14t +C we are not given an initial height so C is 0
h(t)=14t-gt^2/2 letting g=32 and neatening up a bit...
h(t)=14t-16t^2
Answer:
it goes al the way up to 15 and it stops at 5 and the 8 makes the green house
Answer:
41 degrees
Step-by-step explanation:
All three angles in a triangle must add up to 180 degrees. The picture already tells you that B is 63 degrees. This means A and C should both add up 117 degrees. If A is 2x+8 and B is x+7, then A+B is 3x+15. This means that 3x+15 is equal to 117 degrees.
- 3x + 15 = 117
- 3x = 117 - 15
- 3x = 102
- x = 102/3
- x = 34
Now that we know that x is 34, we plug it in. X + 7 becomes 34 + 7 degrees which is equal to 41 degrees.
<span>The Jonestown will be much colder compare to the
Cooperville.
See how the solution goes:
At 1:00, the both share the same temperature
Let X = the temperature of both town
Jonestown
=> 1:00 = x
=> 2:00 = x – 10
=> 3:00 = x – 10 – 8
At 3:00, Jonestown dropped a total of 18 degrees
Cooperville
=> 1:00 = x
=> 2:00 = x – 6
=> 3:00 = x – 6 – 2
At 3:00, Cooperville dropped 8 degrees only.</span>
Answer:
y = 3x + 5
Step-by-step explanation:
First start at your y intercept (5) and use the rise to run ratio (rise 3, run 1) and there is a point on every single one.
1/3 wouldn't work because you rise 1 and go right 3 and that does not match any of the points
Using the two points first gives us a slope of 3
(1, 8) (2, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 8)/(2 - 1)
m = 3/1
m = 3
We also know that 8 cannot be the intercept being as it is the point at x = 1. Therefore, we know that y = 3x + 5 must be the only possible answer.
