Although the square root of 2 times the square root of 14 does equal the square root of 28, it is not simplified to the fullest extent. To simplify separate the square root of 28 into two factors, but make sure one is a perfect square. We can separate into 4 and 7, and since the square root of 4 is 2, we are left with 2* the square root of 7

Biology application. The approximate number of calories C that an animal needs each day is given by
Reika [66]

Answer:

C = 288 kg

Step-by-step explanation:

Given:

C = 72m^2/4

where,

C = approximate number of calories

m = animal mass in kilograms.

Find C when m = 16

C = 72m^2/4

= 72 * (16)^2/4

= 72 * (16)^1/2

= 72 * √16

= 72 * 4

= 288

C = 288 kg

What is a function ? Example
salantis [7]

Answer:

We could define a function where the domain X is again the set of people but the codomain is a set of numbers. For example, let the codomain Y be the set of whole numbers and define the function c so that for any person x, the function output c(x) is the number of children of the person x.

6x – 7y = 16 2x + 7y = 24 (2, 1) (2, 0) (5, 2) (4, –5)
White raven [17]
<span>6x – 7y = 16
2x + 7y = 24

This system is easily solvable by the elimination method as the y-terms are opposites of each other. You may add the two equations together and they will cancel out.

</span>    6x – 7y = 16 
    2x + 7y = 24
+___________
    8x –  0 = 40
           8x = 40
             x = 5

Substitute 5 for x into either of the above equation and solve algebraically for y.

       2x + 7y = 24
    2(5) + 7y = 24
      10 + 7y = 24
              7y = 14
                y = 2

Check work by plugging both x- and y-values into each original equation.

    6x – 7y = 16  =>  6(5) – 7(2) = 16  =>  30 – 14 = 16
    2x + 7y = 24  =>  2(5) + 7(2) = 24  =>  10 + 14 = 24

Answer:
x = 5; y = 2

Henry has a reading list of 10 books that he can choose from to read this week. Identify the constraint for the number of books
lyudmila [28]

Answer:

  • b ≤ 10, which means <em>number of books less than or equal to 10.</em>

Explanation:

In mathematical language a<em> constraint</em> is a limitation on the values that a variable can take.

In this case, the constraint is given by the fact that there are 10 books in the reading list from which Henry can choose to read this week.

So, the number of books that he can read is 1, 2, 3, ..., 10 (at most). This is, 10 books is an upper bound.

To represent an upper bound, you use the inequality symbol ≤, which means less than or equal to.

Henry can read as many as 10 books, so that is less than or equal to 10.

If you call b the number of books, the constrain may be written as:

  • b ≤ 10.

constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set.[1
