A book exhibition was held for four days in a schoolthe number of tickets sold at the counter on the first secend third and four
bija089 [108]

Answer:

7707 tickets

Step-by-step explanation:

From the question we know that:

the number of tickets sold at the counter on

First day = 1094 tickets

Second day = 1812 tickets

Third day = 2050 tickets

Fourth day = 2751 tickets

The total number of tickets sold on all the four days is calculated as:

(1094 + 1812 + 2050 + 2751)tickets

= 7707 tickets

A summer camp has 400 ft of float line with which to rope off three adjacent rectangular areas of a lake for swimming? lessons,
Rashid [163]

Answer:

a) A = x*(400 - 4*x)

b) domain of function A(x) is ( 0 , 100 )

c) dimension of swimming section x = 30 ft maximizes area.

Step-by-step explanation:

Given:

- Total length of float-line used L = 400 ft

- Inner sections length x

Find:

a) Express the total area A as a function of x

b) Find the domain of the function

c) Using the graph, find the dimensions that leads to largest area

Solution:

- The amount of side length of the rectangle can be calculated from the total length given y:

                                 y = L - x - x - x - x

                                 y = L - 4*x

                                 y = 400 - 4*x

- The area of a rectangle is as follows:

                                 A = x*y

- Replace y with the expression derived first:

                                A = x*(400 - 4*x)

- To find the domain of the function we know that A >= 0:

                                 400*x - 4x^2 > 0

                                 x(400 - 4x) > 0

                                 x > 0 , 400 - 4*x < 0

                                 x < 100

- Hence, the domain of function A(x) is ( 0 , 100 )

- From the graph given, we can see that Area is maximum when x = 30 ft. Denoted by the turning point of the graph.

- Hence, the dimension of swimming section x = 30 ft maximizes area.

Can you name a real number that is represented by the square root of negative 36
matrenka [14]
Let's start by knowing what a real number is. A real number is a quantity that can be plotted in a number line or a Cartesian plane. So all integers, rational numbers and radical numbers are real numbers. The only instance when it is not real, is when they are imaginary. These are still numbers, but they have a term 'i' associated with them. Numerically, i = √-1. There is no equivalent quantity to a root of any negative number. It can't be placed anywhere in the number line.

So, for the problem where the number is √-36, we can simplify that to

√-36 = √-1(36) = 6√-1 = 6i

Hence, √-36 is equal to 6i. It can't be expressed into a real number in any way.

However, I'm going to add an additional information. An imaginary number could become real when raised to the power of 2 or 4. This is because

i = √-1
i² = -1
i⁴ = 1

In that case, the number becomes real.
