Answer:

<em>3.94 seconds </em>

Step-by-step explanation:

h = - 16t² + 248

If stone is dropped, then h = 0

- 16t² + 248 = 0

t² = \frac{248}{16}

t = ± \frac{2\sqrt{62} }{4}

t < 0 is a solution of equation, but not a solution of the task

t = \frac{2\sqrt{62} }{4} ≈ <em>3.94 seconds</em>

4. What function represents how much more water can be added to the bucket before it
Elza [17]

The function that represents how much more water can be added to the bucket before it overflows is given as follows:

c(x) = 6x³ + 3x² - 2x - 2.

<h3>How to define the function?</h3>

The function to calculate the space remaining in the pool is given by the subtraction of the capacity function by the function representing the current amount of water in the pool.

The functions in this problem are defined as follows:

  • f(x) = 8x³ + 4x² - 6x + 5.
  • g(x) = 2x³ + x² - 4x + 7.

Then the capacity function is obtained as follows:

c(x) = f(x) - g(x)

c(x) = 8x³ + 4x² - 6x + 5 - (2x³ + x² - 4x + 7)

Then the distributive property is applied to the negative sign as follows:

c(x) = 8x³ + 4x² - 6x + 5 - 2x³ - x² + 4x - 7.

Finally, the like terms are combined, that is, the terms that have the same variable and exponent, as follows:

c(x) = 6x³ + 3x² - 2x - 2.

Given: AD and EG, transversal CH ∠ABC and _______ are same side exterior angles
Arturiano [62]

Answer:

∠EFH

Step-by-step explanation:

If AB and CD are parallel lines and EF is a transversal line, then angles formed on the same side of the transversal line and are exterior to the parallel lines are same side exterior angles.

Same side exterior angles theorem states that same-side exterior angles are supplementary.

From the image attached below:

∠ABC and ∠EFH are same side exterior angles, therefore:

∠ABC + ∠EFH = 180°

Kazeer [188]

Answer:

A

Step-by-step explanation:

Each hour is 30 degrees. 11 to 6 is 7 hours so 30 * 7 = 210 degrees, which is greater than a semicircle, which is 180 degrees.
