Answer:
(x+1)(x+1)(2x−5)(x^2−4x+5)
Step-by-step explanation:
2x^5−9x^4+6x^3+22x^2−20x−25
2x^5−9x^4+6x^3+22x^2−20x−25
=(x+1)(x+1)(2x−5)(x2−4x+5)
Answer:
-15.4
Step-by-step explanation:
Simply just means "solve" or "make the equation shorter"
Step-by-step explanation:
It is given that,
Initial speed of the stone, u = 170 ft/s
It is thrown down from a height of 1020 feet.
We need to its height after t seconds. It can be calculated using second equation of kinematics as follows :
h₀ is initial height, u = -170 ft/s as the stone is throwing down and g = -32ft/s²
Putting values, we get :
Using an exponential function, supposing that the value decays 10% a year, it is found that the current market value is $9,087.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, supposing a decay of 10% a year, and the original value of $13,850, the parameters are A(0) = 13850, r = 0.1.
Hence, the value of the car in 4 years is given by:
A(4) = 9087.
