1225*(1.578*10^-5)=1.933*10^-2

1.578*10^-5= 0.00001578

1225*0.00001578=0.0193305

0.0193305=1.933*10^-2

You buy a car in 2017 for $25,000. The value decreases by 16% each year. How much will the car be worth
pychu [463]

Answer:

The appropriate answer is "10,455.29856".

Step-by-step explanation:

According to the question,

The time will be:

⇒  t = 2022-2017

⇒    = 5

On applying formula, we get

⇒ f(t)=25000(1-.16)^t

On substituting the value of "t", we get

⇒ f(5)=25000(1-.16)^5

⇒         =25000(0.84)^5

On solving the power, we get

⇒         =25000\times 0.4182119424

⇒         =10,455.29856

Answer:

The equation of the axis of symmetry is x = 7

Step-by-step explanation:

Mathematically, we have the equation of the axis of symmetry as;

x = -b/2a

where a is the coefficient of x^2 = 1

b is the coefficient of x which is -14

So, the equation of the axis of symmetry will be;

x = -(-14)/2(1) = 14/2 = 7

So the equation of the axis of symmetry is x =7

Art [367]

Maturity risk for 3 year Treasury security is 0.1%

<u>Explanation:</u>

Given -

Rate of 3 year Treasury security, R3 = 7%

Rate of 6 year Treasury security, R6 = 6.2%

Rate of inflation, Ri = 2.25% next year, 2.5% on 2nd year, 2.5% on 3rd year

Real interest rate, Rint = 4.4%

Maturity risk on 3 year Treasury security, x = ?

Maturity risk for 3 year Treasury security:

R3 = Ri on 3rd year + Rint + x

7% = 2.5% + 4.4% + x

x = 0.1%

Therefore, Maturity risk for 3 year Treasury security is 0.1%
