Answer:

(5.33 + 2h) ≥ 7

h ≥ 0.835

Step-by-step explanation:

Let in the last two days Julian has to practice the drum for h hours each.

Then in two days, he has to practice 2h hours,

He has already practiced 5\frac{1}{3} = 5.33 hours before those last two days.

Therefore, he has practiced this week by (5.33 + 2h) hours.

Now, given that Julian needs to spend at least 7 hours each week practicing the drums.

Hence, we can write the inequality  

(5.33 + 2h) ≥ 7

⇒ 2h ≥ 1.67

⇒ h ≥ 0.835 hours

Therefore, Julian has to practice for 0.835 hours for the last two days of the week. (Answer)

Answer:

y < -8

y > 4

Step-by-step explanation:

Absolute Value Inequality entered :

     |y+2|>6

Step by step solution :
Step 1: Rearrange this Absolute Value Inequality

Absolute value inequalitiy entered

     |y+2| > 6

Step 2: Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |y+2|

For the Negative case we'll use -(y+2)

For the Positive case we'll use (y+2)

Step 3: Solve the Negative Case

     -(y+2) > 6

    Multiply

     -y-2 > 6

    Rearrange and Add up

     -y > 8

    Multiply both sides by (-1)

    Remember to flip the inequality sign

     y < -8

    Which is the solution for the Negative Case

Step 4: Solve the Positive Case

     (y+2) > 6

    Rearrange and Add up

     y > 4

    Which is the solution for the Positive Case

Step 5:

Wrap up the solution

 y < -8

 y > 4

An orange is shot up into the air with a catapult. The function given by h(t)+20+60t-16t² models the oranges height in feet, t s
Ganezh [65]

Answer:

  C, E

Step-by-step explanation:

As a rule, these ballistic motion equations are only applicable for heights above the final resting place. Usually, that is the ground (h=0). Time is always measured as a non-negative quantity beginning at the time of launch.

The function is meaningless after the time the object comes to rest on the ground, so the domain of the function extends from 0 until that time.

These considerations allow us to evaluate the offered statements.

  A. The domain never includes negative values. (A is not a true statement)

  B. The heights are the same at times that are symmetrical around the time of the maximum height. Here, that time is about 1.9 seconds, not 1.5 seconds, so the heights will be different at 1 and 2 seconds after launch. (B is not a true statement)

  C. The graph of the function shows the height reaches 0 at about 4.06 seconds, a little after 4 seconds. (C is true)

  D. Based on our answer to C, we know t=10 is outside the domain of the function. (D is not a true statement)

  E. The value of the function is 20 when t=0, so the function tells us the orange is 20 feet above the ground when it is launched. (E is true)

The true statements are C and E.
