City planners are designing a new dog park. The park will be a square. The area of the park is the square of the side length: area=2802 feet2. Without using a calculator, what is the area of the dog park? Use polynomial identities to support your answer. (thank you)
Step-by-step explanation:
A = 280² ft²
A = (200 + 80)² ft²
A = [200² + 2(200)(80) + 80²] ft²
A = (40000 + 32000 + 6400) ft²
A = 78400 ft²
The required area of the dog park using polynomial is 6771204 feet².
What is polynomial?Polynomial is an algebraic expression that has more than two terms. In other words, it is a combination of different variables with mathematical operations.
Given that,
The area of the park = square of the side length a = 2802 feet².
To find the area of the park, using polynomial use
Formula of area of square = (a)²
= (2802)²
= (2800 + 2)²
Use formula (a + b)² = a² + b² + 2ab
= (2800)² + (2)² + 2 x 2800 x 2
= 6,760,000 + 4 + 11200
= 6771204 feet²
The required area of the dog park is 6771204 feet².

A book sold 33,900 copies in its first month of release. Suppose this represents 9.1% of the number of copies sold to date. How many copies have been sold to date?
Answer:
Around 372,527 (rounding down)
Step-by-step explanation:
To solve this, divide the amount of the books sold in the month it was released (33,900) by the percentage of total copies this number represents (9.1% or .091):
33,900/.091 = 372,527.473 or 372,527 (if you round down) or 372,528 (if you round up)

Question
Mark says that the number 2 is a rational number
because he can write it as the fraction ?
Is Mark correct? Why or why not?
Answer:
yes
Step-by-step explanation:
A rational number is in the form p/q where p and q are both integers and the denominator q is not equal to zero. This means that the set of all real numbers are rational numbers.
Since q can be any integer apart from zero, it means that all integers are rational numbers i.e for q = 1.
Hence 2 which can be written as fraction as 2/1 is a rational number since the denominator (q = 1) is a non zero number
Answer:
Mark is not correct because a fraction is rational only if the numerator and the denominator are both integers.

The coefficient of determination in a simple linear regression model is 64%. What is the correlation level between the dependent and independent variables, assuming a negative relationship between them
Answer: -0.64
Step-by-step explanation:
We know that the coefficient of determination in a simple linear regression model is denoted by [tex]r^2[/tex], which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.
Given, the coefficient of determination in a simple linear regression model is 64%.
i.e.
[tex]r^2= 0.64\\\\\Rightarrow\ r=\sqrt{0.64}=\pm 0.64[/tex]
As there is negative relation between the dependent and independent variables.
Then, the correlation coefficient = -0.64
which of the following are properties of a trapezoid? Select all that apply
Answer: b, d, e
Trapezoids are quadrilaterals (a shape with four sides) and they have two pairs of sides; one pair are parallel, and the other pair are not.
Picture shown below.
The correct properties of a trapezoid are:
They are quadrilaterals.It has one pair of opposite sides that are parallel.It has one pair of opposite sides that are not parallel.A trapezoid is a quadrilateral, which means it has four sides. One defining property of a trapezoid is that it has one pair of opposite sides that are parallel. This means that these parallel sides never intersect.
Additionally, a trapezoid has another pair of opposite sides that are not parallel, which means they do intersect. Unlike a rectangle or square, a trapezoid does not have all sides congruent.
Lastly, the diagonals of a trapezoid do not necessarily intersect at right angles. The angle formed by the intersection of the diagonals can vary in size. These properties collectively distinguish a trapezoid from other quadrilaterals and make it a unique shape.

b. The expected variable value of X; E(X) = 1
Step-by-step explanation:
Given that:
number of cameras = 6
numbers of defective = 3
the probability of defective camera p = 3/6 = 0.5
sample size n = 2
Then X = {0,1,2}
Suppose X is the given variable that represents the number of defective cameras in the sample.
∴
X [tex]\sim[/tex] Bin (n =2, p = 0.5)
The probability mass function of binomial distribution can be computed as :
[tex]P(X =x) = (^n_x) p^x (1-p)^{n-x}[/tex]
For ;
x = 0
The probability P(X=0) [tex]= (^2_0) 0.5^0 (1-0.5)^{2-0}[/tex]
[tex]P(X=0) = \dfrac{2!}{0!(2-0)!} \times 1 \times 0.5^2[/tex]
[tex]P(X=0) =1\times 1 \times 0.25[/tex]
[tex]P(X=0) = 0.25[/tex]
For :
x = 1
The probability P(X=1) [tex]= (^2_1) 0.5^1 (1-0.5)^{2-1}[/tex]
[tex]P(X=1) = \dfrac{2!}{1!(2-1)!} \times 0.5^1 \times 0.5^1[/tex]
[tex]P(X=1) =2 \times 0.5 \times 0.5[/tex]
[tex]P(X=1) =0.5[/tex]
For :
x = 2
The probability P(X=2) [tex]= (^2_2) 0.5^2 (1-0.5)^{2-2}[/tex]
[tex]P(X=2) = \dfrac{2!}{2!(2-2)!} \times 0.5^2 \times 0.5^0[/tex]

Answer:
The radius is [tex] 2\sqrt{15} [/tex]
The center is (3, 3)
Step-by-step explanation:
Equation of circle in standard form with center at (h, k) and radius r:
[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]
We need to complete the square in x and y.
[tex] x^2 + y^2 - 6x - 6y = 42 [/tex]
Separate x-terms and y-terms:
[tex] x^2 - 6x + ~~~~~y^2 - 6y + ~~~~~ = 42 + ~~~~~ + ~~~~~ [/tex]
To complete the square, you square half of the linear term's coefficient.
Linear term in x: -6x
Coefficient: -6
Half of the coefficient: -3
Square half of the coefficient: 9
We need to add 9 to both sides to complete the square in x.
The linear term in y is -6y, so we do the same and we also need to add 9 to both sides to complete the square in y.
[tex] x^2 - 6x + 9 + y^2 - 6y + 9 = 42 + 9 + 9 [/tex]
[tex] (x - 3)^2 + (y - 3)^2 = 60 [/tex]
Now that we have the equation in standard form, we can get the radius and center of the circle.
[tex] r^2 = 60 [/tex]
[tex] r = \sqrt{60} [/tex]
[tex] r = \sqrt{4 \times 15} [/tex]
[tex] r = 2\sqrt{15} [/tex]
The radius is [tex] 2\sqrt{15} [/tex]
The center is (3, 3)

A square has an area of 121 square feet. What is the side length of the square
Answer:
11 feet
Step-by-step explanation:
The area of a square is simply the side of the square squared. This can be written as an equation as follows:
A = l^2
where A is the area of the square and l is the length of a side of the square.
Using this, we can find the length of the side.
121 = l^2
sqrt(121) = sqrt (l^2)
11 = l
Hence, the side length of the square is 11 feet.
Cheers.
Answer:
11
Step-by-step explanation:
[tex]Area = s^2[/tex]
s = side
[tex]A =121\\121 = s^2\\Square\:root\:both\:sides\:of\:the\:equation\\\sqrt{121}=\sqrt{x^2} \\\\11 =x\\x=11[/tex]
Find all values of in the interval [0, 2π] that satisfy the equation. Enter your answers from smallest to largest. (Enter NONE in any unused answer blanks.) $$ 2\sin^2(x) = 1 $$
Answer:
π/4 and 3π/4Step-by-step explanation:
Given the equation [tex]2\sin^2(x) = 1 \\[/tex], we are to find all the values of x in the interval [0, 2π] that satisfies the equation.
Simplifying the equation:
[tex]2\sin^2(x) = 1 \\\\sin^2x = \frac{1}{2} \\\\[/tex]
Square both sides of the equation;
[tex]\sqrt{sin^2x } = \sqrt{\frac{1}{2} } \\\\sin(x) = \sqrt{0.5}\\ \\sin(x) = 0.7071\\\\x = sin^{-1}0.7071\\\\x \approx 45^0[/tex]
The general formula for sin(x) is x = nπ + (-1)ⁿ∝ where n = 0, 1, 2, 3...
Since ∝ = 45° = π/4.
x = nπ + (-1)ⁿπ/4
when n = 1
x = π + (-1)¹π/4
x = π - π/4
x = 3π/4
Hence the values of x within the given interval are π/4 and 3π/4

Answer:
Explanation:
Given;
Mass of a box (m) = 300kg
Area of box (a) = 15m²
Pressure exerted by the box (P) = ?
Acceleration due to gravity (g) = 9.8m/s²
Here,
Pressure = Force / Area

If eight persons are having dinner together, in how many different ways can three order chicken, four order steak, and one order lobster
Answer:
Total number of ways= 144 ways
Step-by-step explanation:
Number of ways 3 can order chicken
= 3!
= 3*2*1
= 6
Number of ways 4 can order steak
= 4!
= 4*3*2*1
= 24
Number of ways 1 can order lobster
= 1!
= 1
Total number of ways= 24*6*1
Total number of ways= 144 ways
The total number of different ways is 144.
Calculation of the total no of ways:Since If eight persons are having dinner together.And, there is three order chicken, four order steak, and one order lobster
Now
Number of ways 3 can order chicken
= 3!
[tex]= 3\times 2\times 1[/tex]
= 6
Now
Number of ways 4 can order steak
= 4!
[tex]= 4\times 3\times 2\times 1[/tex]
= 24
Now Number of ways 1 can order lobster
= 1!
= 1
So, total should be
[tex]= 24\times 6\times 1[/tex]
