Graph the inequality in the coordinate plane. x<-6

puteri [66]

Answer:

You would make a dotted vertical line running through -6 on the horizontal or x axis. The shading would go to the left side of the line since x is less than -6 and the line is dotted because it is only less than and not equal to.

If an intravenous fluid is adjusted to deliver 15 mg of medication to a patient per hour, how many milligrams of medication are

adelina 88 [10]

Answer: 0.125 mg per half minute

Step-by-step explanation:

15mg per hour can be written as 15mg/h

To find out how many mg of medication are delivered per half minute you can convert from hour to minutes

There are 60 minutes in 1 hour, so you can use the conversion factor (1h/60 min) and multiply the expression by it

15 mg/h (1h/60min) = 0.25 mg/min

But the question is per half minute so you have to multiply and divide the previous expression by 0.5 (To obtain 0.5 min in the denominator, which is half minute)

Then,

(0.25 mg/min ) (0.5/0.5) = 0.125 mg/ 0.5 min (0.125 mg per half minute)

Juan wants to change the shape of his vegetable garden from a square to a rectangle, but keep the same area so he can grow the s

sergeinik [125]

The quadratic equation that would model this scenario is

$x^{2} = 2x(x-16)$

Let us take the side of the square = x

Area of the square = x²

Length of the rectangular garden = 2x

Width of the rectangular garden = x-16

So, the area of the new vegetable garden = length*width

Area of the new or rectangular vegetable garden = 2x(x-16)

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

The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by $ax^2+bx+c$ coefficient $x^{2}$ non-zero.

Since it is given that

Area of square garden = area of the rectangular garden

$x^{2} = 2x(x-16)$

Thus, the quadratic equation that would model this scenario is

$x^{2} = 2x(x-16)$
