For this you just substitute -9 for n.
(-9)+4= -5
F(-9)=-5
To make a plot, you have to establish which is the independent and dependent variable. The independent variable (x-axis) is time in years; the dependent variable (y-axis) is mass of tritium in grams.Then, you create a formula.
At year 1,
726(1 - 0.05626) = 685.16 g
At year 2,
685.16 (1 - 0.05626) = 646.61 g
At year 3,
646.61 g (1 - 0.05626) = 610.23 g
and so on and so forth. It is easier to use MS Excel for this step. The final graph is shown in the picture. In ten years' time, the mass of tritium would be 406.87 g. That's almost half of the original mass.
Answer:
The Perimeter is (2x +23 ) inches.
Step-by-step explanation:
Given:
Figure is of a Triangle Shape.
Perimeter of a Triangle is Sum of all the three sides of a triangle.
If a triangle having Sides a, b , and c , then the perimeter of the triangle is given by
Perimeter = a + b + c
Here the sides are (2x - 3 ) , (21 - x ) and ( x +5 ) .
∴ Perimeter = (2x - 3 ) + (21 - x ) + ( x +5 )
∴ Perimeter = 2x + 21+ 5 - 3 +x -x
x -x will cancel each other as x -x =0.
∴ Perimeter = (2x + 23) inches
∴
No, the frequencies do not decrease from the maximum frequency to a low frequency
