(Base x Height) / 2 is the formula
I’m not sure about the estimates but the overall answers should be correct
Answer:
Step-by-step explanation:
By applying tangent rule in the given right triangle AOB,
tan(30°) = 


By applying tangent rule in the given right triangle BOC,
tan(60°) = 
OC = BO(√3)
OA + OC = AC

2√3(BO) = 60
BO = 10√3
OC = BO(√3)
OC = (10√3)(√3)
OC = 30
By applying tangent rule in right triangle DOC,
tan(60°) = 
OD = OC(√3)
OD = 30√3
Since, BD = BO + OD
BD = 10√3 + 30√3
BD = 40√3
≈ 69.3
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

While representing 3 - 4 on the number line, from the starting point 0, we need to show an arrow to three numbers on the right.
Since - 4 is the additive inverse of 4, from the point where the first arrow pointed, we should go 4 points to the left.
Hence, the number line which shows an arrow from 0 to 3, and then from 3 to negative 1 is the correct one.
