Check the explanation
Step-by-step explanation:
Write H(t) for the total sum spent in the United States on health care in year t, where t is measured in years since 2000.
The rate of increase of H(t) was projected to rise from $100 billion per year in 2000 to approximately $190 billion per year in 2010
(a) Find a linear model for the rate of change H'(t)
Slope of line is (190-100)/(2010-2000) = 90/10 = 9 billion dollars per yr
H'(t) - 190 = 9 (t-10) =
H'(t) = 9t + 100 billions dollars per year
(b) Given that $1,300 billion was spent on health care in the United States in 2000, find the function H(t).
H'(t) = 9t + 100 billions dollars per year TAKING INTEGRATION..
H(t) = 9t^2/2 + 100t + C given H(0) = 1300
H(0) = 1300 = C
H(t) = 9t^2/2 + 100t + 1300 billion dollars.
Since x forms a straight line with 2 angles, we know that a straight line is 180 degrees. From there we add 40+50+x=180.
Solving for x gives us 90. Since x and y are vertical angles, we know that y also equals 90.
22) 1/4x the width of the desk is x
23) x-2 Mario's shoe size is x
24) 18x hours worked is x
3x - 5 = x - 7
-x -x
2x - 5 = - 7
+5 +5
2x = -2
Divide 2 on both sides. The answer is x = -1
