What is the volume of a square based pyramid with a side 11 cm and a perpendicular height of 20 cm
Kaylis [27]

V=lw*h/3

So since its a square l and w are the same

11*11 = 121

h=20

20/3=  6.6666666


V=121*6.6666666

V= 806.66667

What is the radius of convergence of the maclaurin series (2x)/(1+x^2)?
kramer
To solve this problem you must apply the proccedure shown below:
 1. You have to find the radius <span>of convergence of the following Maclaurin series:
 </span>(2x)/(1+ x^{2} )&#10;
 2. Let's take the denominator and find the roots:
 1+ x^{2} =0
 x^{2} =-1 \\ x= \sqrt{-1} \\ x1=i \\  x2=-i
 3. The roots are x1=i \\ x2=-i and the distance from the origin is 1.
 Therefore, the answer is: 1

Which of the following sets represents MUN?
Anuta_ua [19.1K]

Answer:

  • <u>Third choice: {3, 4, 6, 7, 9}</u>

Explanation:

<em>M ∪ N</em> means the union of the segments M and N. That is, the complete list of objects that are either in the set M or N.

The circle on the left of diagram shows that the elements inside the set M are 3, 4, 7 and 9.

The circle on the right of the diagram shows that the elements inside the set N are 4, 6 and 7.

The complete list of the numbers in either M or N is 3, 4, 6, 7, and 9 (you must not repeat the elements that belong to both sets but indicate them just once.

So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.

A 35% dextrous solution (35 mg per 100 mL of solution) is given intravenously. Suppose a total of 1.17 L of the solution is give
ludmilkaskok [199]

Answer:

The flow rate in dextrous solution  is 0.117 litres per hour

Step-by-step explanation:

Given:

The volume of fluid which passes per unit time = 1.17 Litres

Time Period = 10 hour

To Find:

The Flow rate per hour = ?

Solution:

Flow rate is defined as rate at which the "{volume of fluid which passes per unit time"

Here the Flow rate is  = \frac{\text{volume of fluid which passes per unit time}}{ time period}

On substituting the values

The Flow rate is =\frac{1.17}{10}

The flow rate is  0.117 litres per hour

Thus 0.117 litres of dextrous solution flows  per hour.
