Answer:

Choice D is correct.

Step-by-step explanation:

We  have to find sum of x and y.

Sum of x and y means to add the values of x and y

Given values of x and y are

x=3.1 ,  y=5.4

Sum of x and y=x+y

x+y=3.1+5.4

write down the numbers,one under the other,with the decimal points, add using column addition

     3.1

   <u>+5.4</u>

     8.5

x+y=8.5 which is the answer.

Which of the following is equivalent to log408 rounded to three decimal places?
il63 [147K]

The answer is: 0.564

The explanation is shown below:

1. To solve this problem you must apply the following proccedure:

2. You have the logarithm expression:

log40(8)=x

3. First, you must apply the following property:

a^{loga(x)} =x

4. Therefore, you have:

40^{log40(8)}=40^{x} \\ 8=40^{x}

5. By applying logarithm on both sides, you have:

log(8)=log(40^{x} )

6. By applying the property log(a)^{b} =blog(a):

log(8)=xlog(40)

7. Solve for x:

x=log(8)/log(40)\\ x=0.564

Step-by-step explanation:

The maximum value of the sin function is at \dfrac{\pi}{2}, when sin is equal to 1. Since you need to multiply pi/12 by 6 to get to pi/2, the maximum amount of people will be at the square after 6 hours. Hope this helps!
