Use the given times and velocities to make two points: (1,4) and (2,2)
Part A:
Slope is the change in Y over the change in X from the two pints you made:
Slope = (2-4) / (2-1 )= -2
Now you have the slope, calculate the Y-intercept
y = -2x + b
Using (1,4)
4 = -2(1) + b = 4 =-2 +b. b = 6
Equation is: y = -2x+6
Part B:
using the above equation replace x with 1, 2, 3, and 4 and solve for the Y
then plot those onto a graph
Answer:
Step-by-step explanation:
0.6 > 2x < 0.7
.6/2 = 0.3......0.7/2 = 0.35
so the number is between 0.3 and 0.35
if its doubled, thousands digit is a 2....not doubled, not a 2
0.311 * 2 = 0.622
I found one...u could be : 0.311
X = half width of tent
Tan(40) = 6/x
x = 6/Tan(40) = 7.15
2x = 14.30 feet the width of the tent
You need the formula: feet per second = feet/second
Now you have to recast the formula to:
feet per second * second = feet , because you want to know the number of feet.
At the bottom is the answer.
At last you have to insert the values:
28 feet per second * 20 seconds = 560 feet
-8.5>-15 is the corrct inequality
