Why is√5 irrational?
A.)because it is less than one
B.)because it has no opposite
C.)because all square roots are irrational
D.)because it cannot be expressed as a ratio of integers

Answers

Answer 1

Answer: The expression x(x + 1) is even for any integer x (since either x or x + 1 is even). So this says that 5 × even + 1 = even, or odd = even. Since there is no integer that is both even and odd, we have reached a contradiction and √5 is irrational. So the answer would be D.) because it cannot be expressed as a ratio of integers

What is rectangular prism?

"It is a three-dimensional solid shape which has six faces that are rectangles."

Formula to calculate the volume of rectangular prism:

V = l w h, where l is the length, w s the width and h is the height of the  rectangular prism.

Given figure consists of two rectangular prisms.

For the smaller rectangular prism,

length(a) = 8 [tex]V_2= 8\times 5\times 5[/tex]cm, width(b) = 8 cm and height(h) = 1 cm

For the larger rectangular prism,

length(p) = 8 cm, width(q) = 5 cm and height(r) = 5 cm

Let [tex]V_1,V_2[/tex] represents the volume of the smaller and larger rectangular prisms respectively.

The volume of the smaller rectangular prism would be,

⇒ [tex]V_1=a\times b\times c[/tex]

⇒ [tex]V_1=8\times 8\times 1[/tex]

⇒ [tex]V_1=64[/tex] cu.cm.

The volume of the larger rectangular prism would be,

⇒ [tex]V_2=p\times q\times r[/tex]

⇒ [tex]V_2=8\times 5\times 5[/tex]

⇒ [tex]V_2 = 200[/tex] cu.cm.

The volume of the figure is:

= [tex]V_1+V_2[/tex]

= 64 + 200

= 264 cubic centimeters

The volume of the figure 264 cubic centimeters.

Calculate the minimum and maximum possible areas. Round your answers to the nearest whole square unit. A rectangular garden plot measures 12 feet by 28.6 feet. The minimum possible area is about ft. The maximum possible area is about ft?​

Answers

Answer:

i. Minimum is 343 square feet

ii. Maximum is 360 square feet

Step-by-step explanation:

The dimension of the rectangular garden plot is 12 feet by 28.6 feet.

1. The minimum possible area can be determined by;

area of a rectangle = length x width

                               = 28.6 x 12

                               = 343.2

The minimum possible area is about 343 square feet.

2. The maximum value can be determined by;

             28.6 ≅ 30.0 (1 sf)

area of a rectangle = length x width

                                = 30 x 12

                                = 360

The maximum possible area is about 360 square feet.

Answers

Answer:

Sales tax is applied to item as they are purchased while property tax is applied to items already owned

Step-by-step explanation:

Sales tax is applied to items as they are purchased while property tax is applied to items already owned. Therefore, option A is the correct answer.

What is the sales tax?

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Property tax is a charge made on real estate that is owned by a person, a business, or another type of legal body. Property tax is most frequently a real estate ad-valorem tax, which is regarded as a regressive tax. It is computed by the local government in the area where the property is situated, and the owner is responsible for paying it.

Sales tax is applied to items as they are purchased while property tax is applied to items already owned. Therefore, option A is the correct answer.

The Sports Brand Company is making a new shoe that has a wholesale price of $40, and it wishes to advertise a retail price of $89.99. What is the markup percentage? Give answer to nearest whole percent. (hint: change decimal to percent, % will not be typed)

Answers

Answer:

Markup Percentage = 125%

Step-by-step explanation:

The wholesale price is $40, the "selling price" is $89.99.

90-40=50 (Profit)

Now that we know the profit , we need to find the percentage.

To find this percentage we can use the formula: (M=Markup percent)

[tex]M=profit/cost*100%[/tex]

In this situation, we can insert PROFIT= 50, Cost=40

M=50/40*100

= 1.25*100

Finda + b, 2a + 3b, |a|, and |a − b|.a = 5i + j, b = i − 2j

Answers

Answer:

Step-by-step explanation:

Given the complex notations a = 5i + j, b = i − 2j, we are to evaluate the following:

1) a + b

= 5i+j + (i-2j)

= 5i+j+i-2j

collect like terms

= 5i+i+j-2j

= 6i-j

Hence a+b = 6i-j

2) 2a+3b

= 2(5i+j) + 3(i-2j)

open the parenthesis

= 10i+2j+3i-6j

collect like terms

= 10i+3i+2j-6j

= 13i-4j

Hence 2a+3b = 13i-4j

3) |a| = √x²+y²

Given a = 5i+j; x = 5, y = 1

|a| = √5²+1²

|a| = √25+1

|a| = √26

4) |a-b|

First we need to calculate a-b

=  a - b

= 5i+j - (i-2j)

open the parenthesis

= 5i+j-i+2j

collect like terms

= 5i-i+j+2j

= 4i-3j

|a-b| = √4²+(-3)²

|a-b| = √16+9

|a-b| = √25

|a-b| = 5

c. If the price increases by $1.00, by how much does the demand decrease?

Answers

Answer:

x = 20,000

p = $40

If the price increase by $1, the demand will decrease by 1000

Step-by-step explanation:

Given:

x = 160 - p

x = number of Robby costumes demanded in thousands

p = price in dollars.

a. How many costumes can be sold at a price of $140?

x = 160 - p

x = 160 - 140

= 20

x = 20,000

20 thousand costumes can be sold at a price of $140

b. What price should be charged if the demand is 120,000 Robby costumes?

x is in thousand

p is in dollars

x = 160 - p

x + p = 160

120 + p = 160

p = 160-120

= 40

p = $40

c. If the price increases by $1.00, by how much does the demand decrease?

x = 160 - p

= 160 - 141

= 19

x= 19,000

If the price increase by $1, the demand will decrease by 1000

Why does the problem of finding the zeros (i.e. the inputs where a function assumes the value zero) receive such disproportionate attention in algebra?A. Because the problem of finding where a function f assumes the value c, i.e. solving f(x) = c, is equivalent to finding where the function f(x)-c assumes the value zero; and c = O is the only number for which f(x) = c can be solved by factoring f(x). B. It's because usually you want to know where a function crosses the x-axis. Crossing a different axis parallel to that is just not that interesting. C. It's because knowing the zeros allows you to determine the end behavior of the function, and the vertical and horizontal asymptotes. D. Because O is the lowest value (i.e. the minimum) that a function can assume. In many math applications, we need to know the minimum value of a quantity.

Answers

Answer:

The answer is C

Step-by-step explanation:

Why does the problem of finding the "zeros" (the inputs where a function assumes the value of zero OR the value inputs for which the function is equal to zero) of a function receive such disproportionate attention in ALGEBRA?

(D) is wrong because zero is not the minimum value that a function can assume. A function could assume or be equal to a negative number or term and negative figures are less than zero.

The answer is (C) because knowing the zeros of a function allows you to determine the end behaviour of the function and the vertical & horizontal asymptotes on a graph/cartesian plane.
