Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. if x is the number of days that lionel practices and y is the total number of hours he spends practicing, which inequality represents this situation?

Required Inequality is y ≥ 45x.

Step-by-step explanation:

Time Lionel play trumpet = 45 minutes

Given,

Number of days Lionel Practices = x

Total number of hours he spend practicing = y

We have to write the inequality satisfying the situation.

Total time he Practices the trumpet = 45 × x = 45x

According to the question,

Total number of hours he spend practicing ≥ Total time he Practices the trumpet

⇒  y ≥ 45x

Therefore, Required Inequality is y ≥ 45x

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
