Answer:
4.8% of of obese children aged 12-19 at the beginning of 1975.
9.15% of obese children aged 12-19 at the beggining of 1986
13.94% of obese children aged 12-19 at the beggining of 1995
Step-by-step explanation:
The percentage of obese children aged 12-19 years in the United States is given by the following piecewise function:
In which t is measured in years.
What was the percentage of obese children aged 12-19 at the beginning of 1975?
This is the value of P when t = 5, so .
For P(5), we apply the first definition of the piecewise function.
At the beginning of 1986?
The value of P when t = 16, so .
For P(16), we apply the second definition of the piecewise function.
At the beginning of 1995?
The value of P when t = 25, so .]
For P(25), we apply the second definition of the piecewise function.
Answer:
Therefore, the perimeter of the triangle is 26.7 units and the area is 22 square units.
Step-by-step explanation:
Given the vertices of a triangle as: A(3, 5), B(− 1, 5), and C(3,− 6)
Since A and B are on the same y-coordinate, we have that:
AB = 3-(-1)=4 Units
Since A and C are on the same x-coordinate, we have that:
AC=5-(-6)=11 Units
Next, we determine the distance BC using the distance formula.
Given: B(− 1, 5), and C(3,− 6)
Therefore:
Perimeter of the Triangle
On plotting the triangle, it forms a right triangle such that the:
Base = 4 Units
Height = 11 Units
Therefore:
Area of a triangle
Therefore:
Area of the Triangle = 0.5 X 4 X 11
=22 Square Units.
Therefore, the perimeter of the triangle is 26.7 units and the area is 22 square units.
