Answer:
4 is the answer
Step-by-step explanation:
The answer to this is 32.
The values of BMW after 2 years and 4 years according to the EXPONENTIAL FUNCTION are $33,462 and $20,358.28
Using the parameters given, we define an decreasing exponential function :
Where,
= initial amount ; r = Rate ; t = time ; A = final amount
Value after 2 years :
t = 2
A = 55000(1 - 0.22)²
A = 55000(0.78)²
A = $33,462
Value after 4 years :
t = 4
A = 55000(1 - 0.22)^4
A = 55000(0.78)^4
A = $20,358.28
Therefore, the value of BMW after 2 years and 4 years $33,462 and $20,358.28 respectively.

Answer:
73.2 ft is the man from the base of the bridge tower.
Step-by-step explanation:
By using the trignometric property
As given
A bird on top of a 200 ft bridge tower sees a man standing on the lower part of the bridge (which is 50 ft above the ground).
The angle of depression from the bird is 26 ̊.
Base = Height of bridge tower - Height of man
AB = AC - DE
= 200 ft - 50 ft
= 150 ft
BE = Perpendicular
Putting all the values in the trignometric property
BE = 150 × 0.488
BE = 73.2 ft
Therefore 73.2 ft is the man from the base of the bridge tower.
Answer:
< x = 120°
Step-by-step explanation:
Step 1:
According to angle sum property,
y + 50 + 70 = 180
Step 2:
x and y are linear pairs, forming a supplementary angle.
Therefore,
x + y = 180
Step 3:
Since they are both equal to 180, equate the values
y + 50 + 70 = x + y
x = 70 + 50
x = 120
