Answer:
HK = 16
Step-by-step explanation:
12^2+x^2=20^2
x = HK
It should be A 6,1 because 6 is the x-axis and 1 is the y-axis
6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity
Remember that the period of a sinusoidal function <span>is the vertical distance between the t-axis and one of the extreme points.</span> From the graph we can infer that the period of the function is 4.5.
Also, the amplitude is<span> the distance between two consecutive maximum or two consecutive minimum points. From the graph we can infer that the amplitude of the function is 0.05 seconds.
We can conclude that the correct answer is: 0.05 seconds; 4.5
