Option 1: log_3\ (8y) is the correct answer

Step-by-step explanation:

Given question is:

\frac{log\ 8y}{log\ 3}

As the log used is natural log, the base is 10.

So,

The log rule used will be:

\frac{log_c\ (b)}{log_c\ (a)} = log_a\ (b)

The given fraction can be written as:

\frac{log_{10}\ 8y}{log_{10}\ 3}

Using the rule mentioned above we can see that

a = 3 and b = 8y

So,

The single logarithmic function is: log_3\ (8y)

Hence,

Option 1: log_3\ (8y) is the correct answer

Two airplanes are carrying food and medical supplies to a country in need. One airplane is carrying 63 meals and 57 medical kits
Tju [1.3M]

Answer:

63m + 57k = 714 ____________ (1)

78m + 57k = 789 ____________(2)

The price of one meal is $5

Step-by-step explanation:

Let the price of one meal be m.

Let the price of one medical kit be k.

One airplane is carrying 63 meals and 57 medical kits and the total cost for those supplies on that airplane is $714.

This means that:

63m + 57k = 714 ____________ (1)

The other airplane is carrying 78 meals and 57 medical kits and the total cost for the supplies on that airplane is $789.

This means that:

78m + 57k = 789 ____________(2)

We now a system containing two linear equations that can be used to solve to problem:

63m + 57k = 714 ____________ (1)

78m + 57k = 789 ____________(2)

To find the price of one meal, we subtract equation (1) from (2) and simplify:

 78m + 57k = 789

<u>- 63m + 57k = 714 </u>_

  15m  = 75

=> m = 75 / 15 = $5

The price of one meal is $5

HELP ITS REALLY URGENT
SSSSS [86.1K]

Answer/Step-by-step explanation:

a. m<h = x°

Two angles to use in finding x are <h and 55°

Angle pair formed: linear pair angles

b. x° + 55° = 180° (linear pair)

Subtract 55° from each side

x + 55 - 55 = 180 - 55

x = 125°

c. Given: m<n = y°

Two angles to use in solving for y are: <h and <n

Angle pair formed: alternate exterior angles

d. m<n = y° (given)

m<n = x° = 125° (as solved in 2b)

Therefore:

y = x (alternate exterior angles are congruent)

thus:

y = 125° (substitution)

If cos(3x)=sin(x+18degrees) what is the value of x
Dafna11 [192]
Try this option:

1. rule: cosα=sin(90°-α), it means that cos 3x=sin(90°-3x);
2. sin(90°-3x)=sin(x+18°); ⇔ 90°-3x=18°+x; ⇔ x=18°.

Answer: x=18°.
