Each of the six letters stands for a different number, 1 through 9. Using the three clues, can you deduce the number represented

by each letter?
A B C
D E F

Answer:

A = 9

B = 2

C = 5

D = 1

E = 8

F = 7

Step-by-step explanation:

A 9 B 2 C 5 = 16

D 1  E 8 F 7 = 16

10   10    12

BxC (2x5) = 10

A+D (9+1) = 10

The average monthly rent for a? 1000-sq-ft apartment in a major metropolitan area from 1998 through 2005 can be approximated by
Lunna [17]

Answer:

  t = 1.107

Step-by-step explanation:

Finding the solution using derivatives involves finding the lower zero of the quadratic that is the second derivative of the given function. That second derivative will be ...

  f''(t) = 12(1.6714)t^2 -6(22.45)t +2(62.27)

  = 20.0568t^2 -134.7t +124.54

  = 20.0568(t -3.35796)² -101.619 . . . . rewrite to vertex form

Then f''(t) = 0 when ...

  t ≈ 3.35796 -√(101.619/20.0568) ≈ 1.10706

__

The solution is perhaps more easily found using a graphing calculator to find the peak of the first derivative. (See attached.) It tells us ...

  t ≈ 1.107

1.1 years after the beginning of 1998 is about 1.2 months into 1999.

Rents were increasing most rapidly in early February of 1999.

when 256 is multiplied by a positive power of 10 number of zeros in the product is related to the power of 10 explain how the nu
Anna [14]

Answer:

If you multiply 256 by 10 powered by k, then the number of zeros in the product is k

Step-by-step explanation:

Let x be any integer, if you multiply x by 10 you will have to add one zero at the right of x. If you multiply by 10 again, you will have to add a second zero at the right, thus if you multiply by 100, you will have to add 2 zeros. If you multiply by 1000 = 10*10*10 = 10³ you will have to add 3 zeros and so on.

Therefore, if you multiply 256 by 10^k, then you will have to add k zeros to 256, and as a consequence, the amount of zeros in the product is equal to the power of 10 we are multiplying.
