Answer: a) , where 'A' is the value of car after 't' years.
b) $12446.784
Step-by-step explanation:
Given: A new car that sells for $21,000 depreciates (decreases in value) 16% each year.
Then a function that models the value of the car will be
, where 'P' is the selling price of car, 'r' is the rate of depreciation in decimal, 't' is the time in years and 'A' is the value of car after 't' years.
Thus after substituting given value, the function becomes
To find the value after 3 years, substitute t=3 in the above function.
Hence the value of car after 3 years=$12446.784

Answer:
800 > x + 375
x < 425
Step-by-step explanation:
800 > x + 375
425 > x
The option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".
<h3>What is mass?</h3>
A tangible body's mass is the amount of matter it possesses. It's also a metric of inertial, or the resistance to velocity when a net force is exerted.
The question is incomplete.
The complete question is:
A box that has a mass of 80 kg slides down a ramp with a 30-degree angle. The free-body diagram shows the forces acting on the box. Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth?
-0.5 m/s²
-4.9 m/s²
-8.5 m/s²
-9.8 m/s²
First we calculate the weight:
W = mg = 80×9.8
W = 784 N
The weight component parallel to the ramp is:
W₁ = Wsin30
W₁ = (784)(sin30)
W₁ = 392 N
From the Newton's second law:
a = F/m
a = 392/80
a = 4.9 m/s²
Thus, the option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".
