√(6-(-1)² + (-2-(-1)²
Answer:
To simplify this expression, we need to first evaluate the terms inside the square root:
(-1)² = 1
(-2 - (-1))² = (-2 + 1)² = (-1)² = 1
Now we can substitute these values and simplify the expression:
√(6 - (-1)² + (-2 - (-1))²)
= √(6 - 1 + 1)
= √6
Therefore, the simplified form of the expression is √6.
Answer:
To evaluate the expression √(6-(-1)² + (-2-(-1)²), we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
1. First, we need to evaluate the expressions inside the parentheses:
-1² = (-1) × (-1) = 1
-2-(-1)² = -2-1 = -3
2. Next, we substitute these values into the expression:
√(6-(-1)² + (-2-(-1)²)
= √(6-1 + (-2-1))
= √(5 - 3)
= √2
Therefore, the value of the expression √(6-(-1)² + (-2-(-1)²) is √2.

Calculate the simple interest due on a 67-day loan of $2600 if
the interest rate is 5%. (Round your answer to the nearest
cent.)
The simple interest due on a 67-day loan of $2600 at a rate of 5% is $23.86.
To calculate this, we can use the following formula: I = Prt, where I is the interest due, P is the principal (or initial loan amount), r is the interest rate, and t is the time in years. We can calculate the time in years by taking the number of days (67) divided by the number of days in a year (365). Therefore, t = 0.1831. We can now plug this into our formula to get I = 2600 * 0.05 * 0.1831, which simplifies to I = 21.50. Therefore, the simple interest due is $21.50.

equipment tells her that the angle of depression from the plane to the beginning of the runway is 11 degrees. to the nearest tenth of a kilometer, what is the horizontal distance between the airplane and runway?
The horizontal distance between the airplane and runway is, 2607.6 meters or 2.6 kilometers
How to relate angle and height to get distance?To solve the problem, we can use the tangent function, which relates the opposite side of a right triangle to its adjacent side:
tanα = opposite/adjacent
where theta is the angle of depression, opposite is the height of the airplane above the ground, and adjacent is the horizontal distance between the airplane and the beginning of the runway.
We can rearrange this formula to solve for adjacent:
adjacent = opposite/tanα
Plugging in the values, we get:
adjacent = 500/tan(11°)
adjacent ≈ 2607.6
Therefore, the horizontal distance between the airplane and the beginning of the runway is approximately 2607.6 meters or 2.6 kilometers when rounded to the nearest tenth of a kilometer.

A quadrilateral is called cyclic if its vertices lie on a circle. Show that opposite interior angles of a quadrilateral are supplementary if and only if the quadrilateral is cyclic. [Hint: Use the preceding problem and facts about circumcircles of triangles]
Opposite interior bof a quadrilateral are supplementary if and only if the quadrilateral is cyclic.
A quadrilateral is called cyclic if its vertices lie on a circle. This means that there is a circumcircle that passes through all four vertices of the quadrilateral. If opposite interior angles of a quadrilateral are supplementary, then the sum of these angles is 180 degrees. This means that the opposite angles of a cyclic quadrilateral are supplementary.
To prove this, let us consider a quadrilateral ABCD that is cyclic. Let O be the center of the circumcircle that passes through all four vertices of the quadrilateral.
Since the quadrilateral is cyclic, angle AOB and angle COD are both subtended by the same arc, and therefore they are equal. Similarly, angle BOC and angle DOA are both subtended by the same arc, and therefore they are equal.
Now, let us consider the sum of the opposite interior angles of the quadrilateral.
Angle A + angle C = angle AOB + angle BOC + angle COD + angle DOA = 2(angle AOB) + 2(angle BOC) = 2(180) = 360
Since the sum of the opposite interior angles of the quadrilateral is 360 degrees, this means that the opposite interior angles of the quadrilateral are supplementary.
Therefore, opposite interior angles of a quadrilateral are supplementary if and only if the quadrilateral is cyclic.

Solve the following inequality involving absolute value. Enter the answer in interval notation.
∣x+4∣>−9
Interval notation is (−∞, −4) U (−4, ∞)
The given inequality is ∣x + 4∣ > − 9. Step-by-step explanation: Absolute value inequalities: Inequalities that contain absolute values are known as absolute value inequalities. The absolute value inequality ∣x + 4∣ > − 9 is given.Inequality means that x can take any value except the value that makes the inequality false. If x satisfies the inequality, we write x ∈ (A, B) or x ∈ [A, B), where A and B are any two values that satisfy the inequality.The inequality ∣x + 4∣ > − 9 implies that the absolute value of x + 4 is greater than −9. The absolute value of x + 4 is always greater than or equal to zero.Therefore, the inequality can be written as∣x + 4∣ > 0This inequality implies that x is not equal to −4.The interval of x satisfying the given inequality is x ∈ (−∞, −4) U (−4, ∞), where U represents the union of two intervals. Therefore, the answer in interval notation is (−∞, −4) U (−4, ∞).Thus, the solution to the inequality |x + 4| > -9 in interval notation is (−∞, −4) U (−4, ∞).

c) The standard deviation of G is 5.8916.
d) The standard deviation of H is 7.0711.
(a) To find the value of k that ensures that f(x) is a proper density function, we need to ensure that the integral of f(x) over its domain is equal to 1:
∫05 (0.1 + kx) dx = 1
0.5 + 12.5k = 1
12.5k = 0.5
k = 0.04
Therefore, the value of k is 0.04.
(b) To find E[X], we need to evaluate the integral of x*f(x) over its domain:
E[X] = ∫05 x(0.1 + 0.04x) dx
E[X] = 0.5 + 0.02(125/3) = 3.3333
To find var[X], we need to evaluate the integral of (x - E[X])2*f(x) over its domain:
var[X] = ∫05 (x - 3.3333)2(0.1 + 0.04x) dx = 1.3889

Find the reference angle θr associated with
each rotation, then find the point (x, y)
associated with θ on the unit circle.
θ =27π/2
Reference angle is θr=
The associated point is (x,y)=
The reference angle for θ = 27π/2 is θr = π/4 and the associated point on the unit circle is (x, y) = (√2/2, √2/2).
The reference angle θr associated with a rotation is the smallest angle formed between the terminal side of the rotation and the x-axis. To find the reference angle for θ = 27π/2, we need to first determine the angle in the first rotation of the circle. Since there are 2π radians in a full circle, we can divide 27π/2 by 2π to find the number of full rotations:
27π/2 ÷ 2π = 27/4 = 6 3/4
This means that there are 6 full rotations and a partial rotation of 3/4. The reference angle for this partial rotation is θr = π/4.
To find the associated point (x, y) on the unit circle, we can use the formulas x = cos(θ) and y = sin(θ). For θ = 27π/2, we can use the reference angle θr = π/4:
x = cos(π/4) = √2/2
y = sin(π/4) = √2/2
Therefore, the associated point is (x, y) = (√2/2, √2/2).
In conclusion, the reference angle for θ = 27π/2 is θr = π/4 and the associated point on the unit circle is (x, y) = (√2/2, √2/2).

a square and a rectangle have the same perimeter. calculate the area of a rectangle if the side of a square is 60cmand the length of a rectangle is 80cm
Answer:
3,200 Square centimeters
Step-by-step explanation:
In order to solve for the perimeter of a square with side lengths of 60, we can use this expression:
60 × 4 = 240(We multiply by 4 because a square has four equal side lengths, and the perimeter is all of the side lengths added up)
Therefore, the perimeter of the square is 240cm.
Now that we know this, we can now take that perimeter, and subtract 160 from it.
(We subtract 160 from it because the length of the rectangle is 80cm, and because a rectangle has two sides that represent the length, we multiply the 80 by 2.)
240 - 160 = 80Now, we can divide the 80 by 2 to get the length of the other 2 sides.
80 ÷ 2 = 40Therefore, the rectangles dimensions are 80cm by 40cm.
What is the area?The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.
To solve for the area of a rectangle, we use the expression:
length × width = heightInserting the numbers into the equation:
80 × 40 = 3200Therefore, the area of the rectangle is 3,200 square centimeters.

opening day as soon as they go on sale and want to get extra tickets so friends could come too. You
have $224.50 and wants to get as many tickets as possible. You want to get at least 5 adult tickets and
4 kids tickets.
Use the ticket prices from your local movie theater or look up the average prices of child and adult
tickets for the movie theater.
In your discussion post, share the equations that you used to model this situation and answer the
following questions:
1. Can you get at least 5 adult tickets and 4 kids tickets?
2. What is the most tickets you could have bought and met the given conditions? What number of
each type of ticket is that?
3. After doing more research, you find out that you can rent out a whole theater for $190. If you rent
the theater out, you can have up to 24 people, regardless of whether they are children or adults. In
what situations would it be a better deal to rent out the theater?
1. The equation for the cost of adult tickets is:
$8.97 x number of adult tickets
The equation for the cost of child tickets is:
$6.79 x number of child tickets
The equation for the cost of renting out the theater is:
$190
2. Yes, you can get at least 5 adult tickets and 4 kids tickets.
3. The most tickets you could have bought and met the given conditions is 9 adult tickets and 8 kids tickets.
4. It would be a better deal to rent out the theater if you had more than 24 people.
You must be aware of the costs of adult and child tickets in order to determine if you can purchase at least 5 adult tickets and 4 child tickets. A cinema ticket for an adult costs $8.97 on average, while a ticket for a child costs $6.79 on average. 4 children's tickets would cost $27.16 and 5 adult tickets would cost $44.85 as a result. You would then have $202.49 remaining, which would be enough to pay for 7 additional child tickets. Thus, you can purchase at least 5 adult and 4 child tickets.
The most tickets you could have purchased while still fulfilling the requirements is nine adult and eight child tickets. The total price would be $135.05. The adult tickets would cost $80.73 and the child tickets would cost $54.32. You would now have $89.45, which is insufficient to purchase any additional tickets.
Renting out the theater might be a great option if you have more than 24 individuals. This is due to the fact that hiring out the theater costs $190 and allows for a maximum of 24 guests, both adults and children. Consequently, renting the theater would be less expensive than purchasing individual tickets if you had more than 24 individuals.

Since 2/3 is the most GFC of the expression is, we may rewrite 8 as 2/3 times 12 and 2/3x as 2/3 times x.
What in mathematics is GCD or HCF?The greatest common factor (GCF) that divides two or more numbers is known as the greatest common divisor (GCD). The highest common factor is another name for it (HCF). For instance, since both 15 and 10 can be divided by 5, 5 is the biggest common factor between both. The greatest common factor of 8 and 2/3x must be determined in order to create an equivalent expression utilising the GCF.
1, 2, 4, and 8 make up the number 8. 2/3x has the following factors: 1/3, 2/3, and x.
We thus have: 8/3 - 2/3x
= (2/3 * 4) / (2/3) - (2/3 * x)
= (2/3)(4 - x) (4 - x)
As a result, using the GCF, the formula for 8/3 - 2/3x is (2/3) (4 - x).

Find the domain and the range of the following functions 1. \( f(x)=3 x^{2}+2 \) 2. \( f(x)=\frac{1}{1-x} \) 3. \( f(x)=\sqrt{x+2} \)
The domain and range of the functions are:
1. \( f(x)=3 x^{2}+2 \) : Domain: all real numbers, Range: all real numbers
2. \( f(x)=\frac{1}{1-x} \) : Domain: all real numbers except x=1, Range: all real numbers except y=0
3. \( f(x)=\sqrt{x+2} \) : Domain: all real numbers greater than or equal to -2, Range: all real numbers greater than or equal to 0
The domain and range of a function are the set of possible inputs and outputs, respectively.
1. For the function \( f(x)=3 x^{2}+2 \), the domain is all real numbers because there are no restrictions on the input. The range is also all real numbers because the output can be any value.
2. For the function \( f(x)=\frac{1}{1-x} \), the domain is all real numbers except x=1, because when x=1, the denominator becomes 0 and the function is undefined. The range is also all real numbers except y=0, because the output can never equal 0.
3. For the function \( f(x)=\sqrt{x+2} \), the domain is all real numbers greater than or equal to -2, because the square root of a negative number is not a real number. The range is all real numbers greater than or equal to 0, because the square root of a number is always positive or 0.
In conclusion, the domain and range of the functions are:
1. \( f(x)=3 x^{2}+2 \) : Domain: all real numbers, Range: all real numbers
2. \( f(x)=\frac{1}{1-x} \) : Domain: all real numbers except x=1, Range: all real numbers except y=0
3. \( f(x)=\sqrt{x+2} \) : Domain: all real numbers greater than or equal to -2, Range: all real numbers greater than or equal to 0

The mean of a set of five score is 27. What must the sixth score be to increase the mean to 28?? Help please
If the mean of five scores is 27, then the number 33 must be added to the previous five scores to make the mean of six scores as 28.
It is given that mean of five scores is 27. If the unknown number x is added to the five scores, the new mean becomes 28. To calculate the value of x, the following equations are considered.
Let us say that the five scores are A, B, C, D and E.
∴ Mean of five scores = (A+B+C+D+E)/ 5 = 27
⇒ (A+B+C+D+E) = 27 × 5 = 135
Now, if sixth score x is added, then mean score becomes 28.
⇒ (A+B+C+D+E+x)/ 6 = 28
⇒ (A+B+C+D+E+x) = 28×6 = 168
Putting the value of (A+B+C+D+E) in above equation, we get:
135 + x = 168
x = 168 - 135 = 33

Write the polynomial as the product of linear factors. 9(x) = x4 - 2x3 + 5x2 8x + 4 g(x) = _________ List all the zeros of the function. (Enter your answers as a comma-separated list.) XE =__________
The polynomial as a product of linear factor [tex]9(x) = x4 - 2x3 + 5x2 8x + 4 g(x)[/tex] are g(x) = (x-2)(x-1)(x+1)(x+4) , all the zeros of function are 2,1,-1,-4.
In order to write the polynomial as a product of linear factors, we must first find its zeros. The zeros of a polynomial are the values of x that make the polynomial equal to zero. The way to find the zeros is to set the polynomial equal to zero, and solve for x.
For this particular polynomial, the equation would be: x^4 - 2x^3 + 5x^2 + 8x + 4 = 0.
We can solve this equation by factoring. When factoring, we look for common factors among the terms and group them together. After factoring, the equation becomes: (x - 2)(x - 1)(x + 1)(x + 4) = 0.
The zeros of the equation are x = 2, 1, -1, -4. This means that the polynomial can be written as the product of linear factors, which is (x-2)(x-1)(x+1)(x+4). The zeros of this function are x = 2, 1, -1, -4.
