1 foot is shorter that 20 centimeters
Answer:
- f(2) = 0.5(2) +3.4
- f(3.5) = 0.5(3.5) +3.4
- f(15) = 0.5(15) +3.4
- f(21.3) = 0.5(21.3) +3.4
Step-by-step explanation:
Put the given weight where x is in the function definition. You're only asked for the expression, not its value.
- f(2) = 0.5(2) +3.4
- f(3.5) = 0.5(3.5) +3.4
- f(15) = 0.5(15) +3.4
- f(21.3) = 0.5(21.3) +3.4
Area of the rectangle: 14.5 x 22 = 319 square meters.
Area the goat can reach ( area of a circle): 3.14 x 2.5^2 = 19.625 square meters.
Now subtract the area of the circle from the area of the rectangle:
319 - 19.625 = 299.375 square meters. (Round the answer as needed.)
Remember that cos(0) represents the x value of a point on the unit circle. The period for the unit circle is 2π in radians which means that adding or subtracting 2π will get you back to the same point which has the same cosine.
Examples: cos(2π),cos(100π),cos(60π)
