Answer:
$ 236.20
Step-by-step explanation:
where n is the number of years.
v = 400(1 - 0.10)ⁿ
v = 400(0.9)⁵ = 236.196
Answer:
Correct option is A.
Step-by-step explanation:
Given the following functions we have to choose the option which illustrates a change in amplitude.
Multiplying a sine or cosine function by a constant changes the graph of the parent function i.e results in change in the amplitude of function. Amplitude is the measure of distance from the sinusoidal axis to the maximum or the minimum.
Option A: y = 3cos4x
The parent function is f(x) = cos x.
The amplitude of function changes from 1 to 3.
Option B: y = 1+sinx
The parent function is f(x) = sin x
The amplitude remains same i.e 1
Option C: y = -2-cos(x - pi)
Here also remains same.
Option D: y = tan 2x
The tangent function does not have an amplitude because it has no maximum or minimum value.
Hence, correct option is A.
Answer:
v = 33.8 m/s
Step-by-step explanation:
Given that,
The initial velocity of the truck, u = 0
Acceleration of the truck, a = 3.6 m/s²
Time, t = 9.4 s
We need to find the car's final velocity. Let v is the final velocity.
Using equation of kinematics as follows :
v = u +at
Since, u = 0
Hence, the final velocity of the car is 33.8 m/s.
