Mike discovered that the pool in his backyard is leaking slowly. The pool holds 16,111 gallons of water, and is leaking at a rat

Lera25 [3.4K]

Answer:

There are 15,112 gallons of water will remaining in the pool ⇒ answer D

Step-by-step explanation:

* Lets explain how to solve the problem

- The rate is the ratio between two related quantities in different units

- The pool is leaking slowly at rate 9 gallons per second that means the

quantity of the water in the pool decreased 9 gallons each day

- The find the remaining gallons in the pool after 111 days, find the

amount of water has leaked from the pool in these days

∵ The rate of leaking is 9 gallons per day

∵ Mike does not replace the water that has leaked from the pool

- The amount of water leaked in some days = the rate of leaking

× the number of days

∵ The number of days is 111 days

∵ The amount of water lacked = 9 × 111 = 999 gallons

∵ The amount of water remaining in the pool after some days =

the total amount in the pool - the amount of leaked in that days

∵ The pool holds 16,111 gallons of water

∴ The amount of water remaining = 16111 - 999 = 15112 gallons

* There are 15,112 gallons of water will remaining in the pool

Use calculus to find the area a of the triangle with the given vertices. (0, 0), (6, 2), (4, 8)

Vilka [71]

The area of the triangle with vertices $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ is

$\frac{1}{2}\left|\begin{array}{ccc}1&x_1&y_1\\1&x_2&y_2\\1&x_3&y_3\end{array}\right|$ .

Inserting numerical values, the are of the triangle with vertices (0, 0), (6, 2), (4, 8) is

$\Delta = \frac{1}{2}\left|\begin{array}{ccc}1&0&0\\1&6&2\\1&4&8\end{array}\right |\\
\Delta = 0.5(48-8)\\
\Delta = 20 \;square\; units$

Which of the following constants can be added to x2 + x to form a perfect square trinomial?

solmaris [256]

The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.

<h3>What is a quadratic equation?</h3>

It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.

The expression is x² + x.

Then the constant should be added to form a perfect square trinomial.

Then the constant will be

The square of the half of the coefficient of the variable x is to be added to make a perfect square.

Then the constant will be 1/4.

Then the perfect square will be

$\rm \rightarrow x^2 + x + \dfrac{1}{4}\\\\\\\rightarrow x^2 + 2 \times \dfrac{1}{2} x + \left (\dfrac{1}{2} \right )^2\\\\\\\rightarrow \left (x + \dfrac{1}{2} \right)^2$

-73 greater than or equal to 15 + 11x

Alecsey [184]

-73 ≥ 15 + 11x
so the first thing you should do is to add -15 on both sides of the equation so you will have:
-73 -15 ≥ 11x
- 88 ≥ 11x
so the answer is:
-88/11 ≥ x or -8 ≥ x :)))
i hope this is helpful
have a nice day
