We have the given I = 10^-1 and I₀ = 10^-12.

Simply plugging in the values to the equation, we have:
L = 10log(10^-1/10^-12)
L = 110 Db

The answer is D.

(I used a scientific calculator in solving for L).

14. Veronica is choosing between two health clubs.
trapecia [35]

Answer:

The total cost for  each health club would be the same after 4 months.

Step-by-step explanation:

Answer:

The total cost for  each health club will be the same after 4 months.

Step-by-step explanation:

For studio A:

Membership fee = $22.00

Monthly Fee = $24.50

The equation for studio A:

  • A = 22 + 24.5x

For studio B:

Membership fee = $47.00

Monthly Fee = $18.25

The equation for studio B:

  • B = 47 + 18.25x

Let 'x' be the month of membership

We must have to find the value of month or 'x' for which the total cost at each health studio is the same.

i.e. when A = B

Hence, the expression will be

A = B

22 + 24.5x = 47 + 18.25x

Please note that if we put x=4, the L.H.S and R.H.S of the equations become the same

i.e.

22 + 24.5(4) = 47 + 18.25(4)

      22 + 98 =  47 + 73

         120 = 120

so, at x=4 the equations become the same.

Therefore, the total cost for  each health club would be the same after 4 months.

svet-max [94.6K]

Answer:

- 38

Step-by-step explanation:

Here in this question, we have to simplify a certain numeric term to get a simple answer.

The expression is ( - 6 times + 3 ) + ( 5 times - 4 )

= - ( 6 times 3 ) + (5 times - 4)

= - ( 6 × 3 ) - ( 5 × 4 )

= - 18 - 20

= - 38 (Answer)
