You are considering a 5/1 ARM. What does the 1 represent?
Lerok [7]

Answer:

  B. The number of years between adjustments in the interest rate

Step-by-step explanation:

The "5" in "5/1" means there will not be any adjustment in interest rate for the first 5 years.

The "1" in "5/1" means interest rates may be adjusted at 1-year intervals after the initial 5-year period.

Help me answer these questions please 15, 19 and 20 please​
SpyIntel [72]

Answer:

15) K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

Step-by-step explanation:

We are to find the derivative of the questions pointed out.

15) K(t) = 5(5^(t)) - 2(3^(t))

Using implicit differentiation, we have;

K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P(w) = 2e^(w) - (2^(w))/5

P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q(W) = 3w^(-2) + w^(-2/5) - w^(¼)

Q'(w) = -6w^(-2 - 1) + (-2/5)w^(-2/5 - 1) - ¼w^(¼ - 1)

Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

Nina thought of a number. She called her number y. She added 14 to her number, divided the result by 6, and she got 12. What was
Leto [7]
Y=58
Y+14/6=12
Cross multiply to solve
So y+14=72 then subtract 14 so
Y=58
