Answer:

12.56 in squared

Step-by-step explanation:

the formula for area is      radius x radius x pi

So you do 2x2x3.14

(I would just do 4x3.14)

And then you get 12.56

Answer:

6 cm and 18 cm.

Step-by-step explanation:

We are given that:

The perimeter of any rectangle is:

To determine the dimensions of the rectangle, we need to determine the value of "x". The word "dimensions" are the length and the width of the rectangle. Since the question has not stated the length and width, we can consider the length as x and the width as 3x.

It is also given that the perimeter of the rectangle is 48 cm. Thus, the formula with the length and the width substituted is equivalent to 48 cm.

It is required for the expression on the left hand side to be simplified. This can be done by combining like terms.

Then, we can divide 8 both sides to isolate the coefficient from "x". Once the coefficient of "x" is isolated, we will obtain the value of "x".

Finally, substitute the value of "x" into the length and the width. We considered the length to be "x" and the width to be "3x". Therefore,

Thus, the dimensions of the rectangle are 6 cm and 18 cm.

The angle measure of the piece is the amount of space left  between the vertices

The angle of the piece left over after cut A is 35 degrees

In cut A, we have the following expression

x + 55 = 90

Subtract 55 from both sides to determine the measure of angle left

x = 35

Hence, the angle of the piece left over after cut A is 35 degrees

Answer:

53.4

Step-by-step explanation:

We first do

55 + 57 + 60 + 45 + 50

55 +57 + 45 + 110

57 + 100 + 110

57 + 210

267

Now we do 267 divided by 5.

This is 53.4

The statements true are B)The data is best represented by a quadratic model. and C) If the price is $5 per unit, the expected profit is approximately $4,686.

We have the Information regarding the data is given below

Expected profit is the probability of receiving a certain profit times the profit, and the expected cost is the probability that a certain cost will be incurred times the cost.

The data should be best presented by  the quadractic model.

In the case when the price should be $5 per unit so the profit should be $4,686.

Therefore,option B and option C these two options are correct.

The equation which shows one way to determine the factors of x3 4x2 5x 20 by grouping is x²(x + 4) + 5(x + 4).

The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.

The polynomial equation given in the problem is,

[tex]x^3 +4x^2 +5x+ 20[/tex]

Take out the greatest common factor from the first two term which is x^2 and from the last two terms which is 5 as,

[tex]x^2(x +4)+5(x+ 4)\\[/tex]

Simplify it further,

[tex](x+4)(x^2+5)[/tex]

One graph appears skewed, and one graph appears symmetrical because the interval 2 stem and leaf plots is not consistent, statement third is correct.

It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.

The number line goes from 8 to 72 in incremental of 8, such as:

8, 16, 24, 32, 40, 48, 56, 64, 72

The whiskers range is from 8 to 71 and

Box ranges from 23 to 47.

The line divides the box at 38.

The mid-point of the line plot is at 40 and at first inspection, the stem and leaf plot appears to be accurate. In the stems, however, 5 is omitted entirely, giving the pattern a symmetrical rather than skewed appearance.

Thus, one graph appears skewed, and one graph appears symmetrical because the interval 2 stem and leaf plots is not consistent, statement third is correct.

Answer:

36 sq in

Step-by-step explanation:

First find the area of the square: 12*12 = 144 in^2

next find the area of 1 circle, im assuming the circles are tangent to the sides of the square and to each other, so each circle has a radius of 12/4 or 3in, the area of each circle is then pi*3^2 or 27 in^2

the total area of the 4 circles is then 27*4 = 108in^2

144-108=36in^2

Step-by-step explanation:

You can say that a function take input and outputs something back. for example, let's y = X + 3. You may think this is a equation.Yeah it is but it is also a function. The original function notation is for example f(X) = X+3.But we set y = f(X) so it turn out to be y=X+3.Basically these two have the same meaning.X is a input in the function above.If you set X= 5,the input is now 5 and you will get a kinda output of 5+3 =8.so y= 8 or f(5) = 8.That's all.You can check out more on the internet.

A value in the interval (-∞,-2√5] ∪[2√5,∞) will give the two real number solutions.

Given quadratic equation is:

[tex]x^{2} +bx+5=0[/tex]

Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0.

To have two real number solutions the discriminant of a quadratic equation should be greater than or equal to zero.

[tex]b^{2} -4(1)(5)\geq 0[/tex]

[tex]b^{2} -20\geq 0[/tex]

[tex]b^{2} -(2\sqrt{5} )^2\geq 0[/tex]

[tex](b+2\sqrt{5} )(b-2\sqrt{5} )\geq 0[/tex]

[tex]b\in(-\infty,-2\sqrt{5} ]\cup [2\sqrt{5} ,\infty)[/tex]
