Ben and Cam are scuba diving. Ben is 15.815.8 meters below the surface of the water. Cam is 4.24.2 meters above Ben. What is Cam

Semmy [17]

Answer:

Option B - 11.6 m below the surface of water.

Step-by-step explanation:

Given : Ben and Cam are scuba diving. Ben is 15.815.8=15.8 meters below the surface of the water. Cam is 4.24.2= 4.2 meters above Ben.

To find : What is Cam's position relative to the surface of the water?

Solution :

Ben is 15.8 meters below the surface of the water.

Cam is 4.2 meters above Ben.

So, Cam is below the surface of water by $15.8-4.2=11.6$ meter.

Therefore, Option B is correct that Cam is 11.6 meters below the surface of the water.

Fill in the missing values to make the equations true.

azamat

Step-by-step explanation:

Some of the property of log are as follows :

1. $\text{log a}-\text{log b}=\text{log} \dfrac{\text{a}}{\text{b}}$

2. $\text{log a}+\text{log b}=\text{log}(a{\cdot} b)$

3. $\text{log}a^n=n\ \text{log} a$

Now coming to question,

(a) $\text{log 5}-\text{log 8}=\text{log} \dfrac{\text{5}}{\text{8}}$ (using property 1)

(b) $\text{log 1}+\text{log 3}=\text{log}(1{\cdot} 3)=\text{log} 3$ (using property 2)

(c) $\text{log} 4=\text{log} 2^2=2\ \text{log} 2$ (using property 3)

Hence, this is the required solution.
