Which expression is a perfect cube?

Answer:

1. D

2. A

Step-by-step explanation:

To determine the type of line, find the slope.

1. Find the difference in y values over the difference in x values. Calculate the slope using the formula:

[tex]\frac{y_2-y_1}{x_2-x_1} = \frac{6-2}{4-6}=\frac{4}{-2}=-2[/tex]

[tex]\frac{y_2-y_1}{x_2-x_1} = \frac{1--1}{1-5}=\frac{2}{-4}=\frac{-1}{2}[/tex]

These are reciprocals of each but not the negative or opposite signs of each other. This is none.

2. Find the difference in y values over the difference in x values. Calculate the slope using the formula:

[tex]\frac{y_2-y_1}{x_2-x_1} = \frac{6-0}{4-7}=\frac{6}{-3}=-2[/tex]

[tex]\frac{y_2-y_1}{x_2-x_1} = \frac{3-1}{5-1}=\frac{2}{4}=\frac{1}{2}[/tex]

These are reciprocals of each and the negative or opposite signs of each other. These are perpendicular.

Kiran is correct. (I agree with Kiran.)

_____

Suppose the length and width are L and W. The Pythagorean theorem says the diagonal distance is ...

... d = √(L² +W²)

If the dimensions are doubled, the the diagonal distance becomes ...

... D = √((2L)² +(2W)²) = √(4(L² +W²)) = 2√(L² +W²)

... D = 2d

Answer:

Kiran's statement is correct.

Step-by-step explanation:

Kiran says that if the field were twice as long and twice as wide, then it would be twice the distance to the far corner.

Let the original length be = l

Let the original width be = w

Let the original diagonal be = d1

As per Pythagoras theorem,

[tex]d1^{2} =l^{2} +w^{2}[/tex]

When the dimensions are twice the original;

Length = 2l

Width = 2w

Diagonal = d2

We get the formula :

[tex]d2^{2} =2l^{2} +2w^{2}[/tex]

[tex]d2^{2} =2(l^{2} +w^{2})[/tex]

Or [tex]d2^{2} =2d1^{2}[/tex]

So, we can say that Kiran is correct.

Similar triangles have proportional corresponding sides and congruent corresponding angles.

For similar triangles we write

ΔGHI ~ ΔJKL

In these similarity expressions, the order of the vertices is meaningful.  Here it tells us that G and J are corresponding vertices, as are H and K, as well as I and L.   So ∠G≅∠J, ∠H≅∠K and ∠I≅∠L.

False

Here is a counterexample:

Let x = 3. Then

  [tex]\sqrt{3x} = \sqrt{3\cdot 3} = \sqrt{9} = 3[/tex]

but [tex]x\sqrt{3} = 3 \cdot \sqrt{3} \ne 3[/tex]

So these expressions are not equivalent

The statement is false the expression √3x is equivalent to the expression x√3.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division

let us check by an example put the value of x = 3

[tex]\sqrt{3x} \ \ \ =\ \ \ x \sqrt3[/tex]

[tex]\sqrt{3\times 3}\ \ \ \ = \ \ \ \ 3 \sqrt3[/tex]

[tex]\sqrt9 \ \ \ \ \neq \ \ \ \ \ 3\sqrt3[/tex]

Here we can see that the two values are not equal.

Therefore the statement is false the expression √3x is equivalent to the expression x√3.

6f - 12 = -4f + 6

Add 4f to both sides.

10f - 12 = 6

Add 12 to both sides.

10f = 18

Divide both sides by 10.

f = 1.8 = 1 4/5

multiply 19.2x9.5=182.4

Hi!

Solution:

19.2 x 9.5 = 182.4

Answer:

C. No, Cesar's answer should be closer to 180.

The "meter" is a larger unit than the "centimeter." Every time you need to convert a larger metric unit to a smaller one, you must multiply to find a greater value.

there are 100 cm in a meter so the fraction would be 8/100 or simplified 2/25

diameter = 5

the diameter is twice the radius

diameter = 2.5 × 2 = 5

Answer and Step-by-step explanation:

Without dividing, I can decide whether the quotient (the number obtained after dividing one number—the numerator—by another—the denominator) of 7.16 ÷ 4 is either less than or greater than 2, by multiplying the denominator (which is 4) by 2, getting the product/result, and comparing the numerator (which is 7.16) with it:

I know that the product of 4 and 2 is 8; however, when comparing 7.16 with 8, I know that it is less than 8; thus I can quickly decide that the quotient of 7.16 ÷ 4 will be less than 2.

the graph on the top right

the broken line is the graph of y = - 2x - 2

the slope m = - 2 indicating the graph slopes down from left to right and crosses the y - axis at (0, - 2)

the shaded region above and to the right of the broken line indicates that y is greater than - 2x - 2

top right represents y > - 2x - 2

Area = length * width

width = w

length = 2w+7

A = (2w+7) * w

250 =2w^2+7w

0 = 2w^2 +7w-250

w is the width, hence length is 2w + 7 ( 7 more than twice the width )

area = length × width = w( 2w + 7 ) = 250

2w² + 7w - 250  = 0 ← in standard form

Answer:

the unit cost per item

Step-by-step explanation:

The description of the graph tells you what the slope means. The slope is the (change in) y-value (cost) per (change in) x-value (item), thus is cost per item.

The slope of the line from the origin to a point is the average cost for that number of items. The slope of a tangent line at a point on the curve is the marginal cost for that number of items.

When the curve is linear and goes through the origin, the slope is the same everywhere and is the cost per item. (It is also the average cost and the marginal cost, where that is of interest.)

The slope of the graph, which represents the rate of change between the number of identical items purchased and the total cost, means the unit cost per item.

In the given context of a graph where the x-axis represents the number of identical items purchased and the y-axis represents the total cost in dollars, the slope of the graph represents the unit cost per item. This is because the slope of a line is a measure that describes the rate of change between the independent and dependent variables. It tells us how the dependent variable (in this case, total cost, represented by 'y') changes for every one-unit increase in the independent variable (in this case, number of items purchased, represented by 'x'), on average.  

Therefore, when you buy more items (increase in 'x'), the total cost ('y') increases. Hence, the rate at which 'y' is increasing per unit 'x' is actually the cost per item. This concept is fundamental in understanding how variations in quantity purchased impact the total cost, applicable in contexts from shopping to major business transactions.

[tex](2+4i)^3=8+48i-96-64i=-88-16i[/tex]

note that (a + b)³ = a³ + 3a²b + 3ab² + b³

(2 + 4i)³ ← with a = 2 and b = 4i noting that i² = (√-1)² = -1

= 2³ + (3 × 4 × 4i ) + ( 3 × 2 × 16i² ) + ( 4i )³

= 8 + 48i  - 96 - 64i

= - 88 - 16i

2112 because i did 528x4=2112

The company's total profit for four months considering it maintains a consistent monthly profit (loss) of -$528 would equate to -$2112.

If a company had a profit of -$528 in January and continues to have the same profit for four months, you simply multiply -$528 by four.

To calculate:

So, the total profit (or in this case, loss) of the company after 4 months will be -$2112.

Answer: y = 1/7(x) or y = x/7

Step-by-step explanation:

Hey there! Thank you for submitting your question to Brainly!

In order to vertically compress the equation y = x by 1/7, we would simply need to multiply x by 1/7. Therefore, this gives us the equation y=1/7(x) or y=x/7.

Hope this helps!! :)

A vertical compression by a factor of 1/7 to the equation y=x results in the new equation y=1/7x where each y-value of the original function is 1/7 of its original height.

A vertical compression by a factor of 1/7 to the equation y=x results in the new equation y=1/7x. In vertical compression, each y-value of the original function is multiplied by the factor of compression, in this case, 1/7. Thus y=x becomes y=1/7x. This means for any x value in the original function, the corresponding y value in the new function is 1/7 of its original height. For example, where x was 1, y was also 1 for the original equation. In the new equation, when x is 1, y is now 1/7.
