y = 3* (1/3)^x
Step-by-step explanation:
Step 1 :
One way to find the function of a given graph is to substitute different values of x , determine the y value and see if matches the graph.
Step 2 :
Consider the function, y = 3* (1/3)^x.
When x = 0, y = 3
x = 1 , y = 1
x = 2 , y = 1/3
x = 3 , y = 1/9
We see from the graph that these points are plotted in the graph
Hence the function plotted in the graph is y = 3* (1/3)^x

55 deg 30 Minutes = 55.5 degrees
sin = opp/hyp
sin(55.5) = altitude/10
Altitude = 10*sin(55.5)
Altitude = 10 * sin(55.5) = 8.241261886
Rounded to nearest 10th
Altitude = 8.2 cm
b. for base use Low of Cosines
Let C = base
Side A and B = length 10 Cm
c^2 = 2*a^2 -2a^2*cos(<C)
<C = 180 - 2*55.5 = 180 -111 = 69 degrees
c = sqrt ( 2a^2 - 2a^2*cos(<C)
c = sqrt ( 2*100- 200*cos(69))
c = sqrt (200 - 200*cos(69) ) = 11.32812474
Answer base
c = 11.3 cms
c.
Area = (1/2)*b * h
Area = (1/2)*(answer a * answer b)
Area = (1/2)* 11.32812474* 8.241261886 = 46.67902132
Area = 46.7 (rounded)
Area = ( 1/2) * a*b*sin(<C) = (1/2)*10*10*sin(69) =
Area = 50* sin(69) = 46.67902132
Area = 46.7 (rounded)</span>

Answer:
49 inches
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
7 inches x
-------------- = -----------------
8 inches 56 inches
Then (8 ")x = (7 ")(56 "), and
x = 392/8 inches = 49 inches.
The actual width of the helicopter is 49 inches.
Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
