Plugging -6 in for x, we get -2sqrt(-6-7+1)=sqrt(something negative) which is clearly not possible.
Plugging -6 in for f(x), we get -6=-2sqrt(x-7+1) and 3=sqrt(x-7+1). Squaring both sides, we get 9=x-7+1 and by adding both sides by 6 we get 15=x, therefore having (15,-6) and proving that -6 is in the range, but not the domain (B)
Answer:
I think the answer is B because there are 2 A's on spinner 1 than spinner 2
Assuming that the equations are (x+7) and (3x-8) because the first equation does not have a sign these are the steps. When you multiply you will get 3x^2+21x-8x-56. After this you will simplify and you will get your final answer which is 3x^2+13x-56. Also if I used the wrong equations please let me know and I can help you with the correct ones.
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%
