Answer:
To find the values of a and b that make the power function y = ax^b pass through the points (2,5) and (6,9), we can use the following system of equations:
5 = a2^b
9 = a6^b
We need to solve for a and b in this system.
One way to do this is to divide the second equation by the first equation, which eliminates a and gives:
9/5 = (6/2)^b
Simplifying this gives:
9/5 = 3^b
Taking the logarithm of both sides (with any base) gives:
log(9/5) = log(3^b)
Using the logarithmic property that log(a^b) = b*log(a), we get:
log(9/5) = b*log(3)
Solving for b, we get:
b = log(9/5) / log(3)
Plugging this value of b into one of the original equations (e.g., the first one) gives:
5 = a*2^(log(9/5)/log(3))
Solving for a, we get:
a = 5 / 2^(log(9/5)/log(3))
Find A - B Enter the element in row 3 column 2. A=[[-1,0,2],[4,1,-1],[2,0,1]],B=[[2,1,0],[-1,0,2],[4,-3,-1]]
A - B is 5.
To find A - B, subtract each corresponding element in B from the corresponding element in A.
For the element in row 3, column 2, it is 2 - (-3) = 5.
Therefore,
the element in row 3, column 2 of A - B is 5.

that the method of completing the square can be used to solve the roots?
A. 64
B. 49
C. 36
D. 25
The number that must be added to both sides of the equation x2 + 12x = 13 so that the method of completing the square can be used to solve the roots is 36. The correct answer is C. 36.
To complete the square, we need to add the square of half the coefficient of the x term to both sides of the equation. In this case, the coefficient of the x term is 12, so half of it is 6. The square of 6 is 36, so we need to add 36 to both sides of the equation. Hence the correct option is C) 36.
The equation then becomes:
x2 + 12x + 36 = 13 + 36
Simplifying the right side of the equation gives us:
x2 + 12x + 36 = 49
Now we can factor the left side of the equation into a perfect square:
(x + 6)2 = 49
From here, we can use the square root property to solve for x:
x + 6 = ±√49
Solving for x gives us:
x = -6 ± 7
So the roots of the equation are x = 1 and x = -13.

what is the simplest form of the radical expression sqrt2+sqrt3/sqrt2-sqrt3
please show work
Answer:
-5 - 2sqrt6
Step-by-step explanation:
To simplify (sqrt2+sqrt3)/(sqrt2-sqrt3), we can rationalize the denominator, which involves multiplying both the numerator and denominator by the conjugate of the denominator.
The conjugate of sqrt2-sqrt3 is sqrt2+sqrt3, so we can multiply both the numerator and denominator by sqrt2+sqrt3:
(sqrt2+sqrt3)/(sqrt2-sqrt3) * (sqrt2+sqrt3)/(sqrt2+sqrt3) = ((sqrt2+sqrt3)(sqrt2+sqrt3))/((sqrt2-sqrt3)(sqrt2+sqrt3))
Expanding the numerator and simplifying, we get:
(sqrt2+sqrt3)^2 / (sqrt2^2 - sqrt3^2)
= (2 + 2sqrt2sqrt3 + 3) / (2 - 3)
= (5 + 2sqrt6) / (-1)
= -5 - 2sqrt6
Therefore, (sqrt2+sqrt3)/(sqrt2-sqrt3) simplifies to -5 - 2sqrt6.
The simplest form of the expression (√2 + √3) / (√2 - √3) is - (5 + 2√6).
We have,
To simplify the expression (√2 + √3) / (√2 - √3), we can rationalize the denominator by multiplying both the numerator and the denominator by the conjugate of the denominator.
The conjugate of (√2 - √3) is (√2 + √3).
Multiplying the numerator and denominator by (√2 + √3), we get:
[(√2 + √3) x (√2 + √3)] / [(√2 - √3) x (√2 + √3)]
Expanding both the numerator and denominator:
[(√2 + √3)(√2 + √3)] / [√2 x √2 - √2 x √3 + √3 x √2 - √3 x √3]
Simplifying:
[2 + 2√2√3 + 3] / [2 - 3]
Combining like terms:
[5 + 2√6] / [-1]
Since the denominator is -1, we can multiply both the numerator and denominator by -1 to simplify further:
[5 + 2√6] / 1
Finally, we have:
(5 + 2√6)

What are the other three angle measures if ∠1 has a measure of 45°?
The measures of the other three angles are: ∠2 = ∠3 = 67.5° and ∠4 = 0°.
Define an angle?An angle is a geometric figure formed by two rays that share the same endpoint called vertex. It is measured in degrees, radians or gradians and is usually denoted by the vertex letter in its center, with the endpoints labeled by two other letters or points.
Since the sum of the measures of the angles in a triangle is 180 degrees, we can use this information to find the measures of the other three angles.
If ∠1 has a measure of 45°, then we know that the sum of the measures of ∠2 and ∠3 is 135° (180° - 45°).
If the triangle is isosceles, then ∠2 and ∠3 have the same measure. Therefore, we can divide 135° by 2 to get:
∠2 = ∠3 = 67.5°
Finally, we can use the fact that the angles of a triangle add up to 180° to find the measure of ∠4:
∠4 = 180° - 45° - 67.5° - 67.5° = 0°

"Find the x-values (if any) at which f is not
continuous. Which of the discontinuities are removable? (Use
k as an arbitrary integer.)
f(x) = [[x − 2]]
Please explain how to solve I'm stuck."
Therefore, f(x) = [[x − 2]] is discontinuous at x = k - 2 and x = k + 2. The discontinuities at these points are removable.
The function f(x) = [[x − 2]] is discontinuous at any value of x that is two units away from an integer. That means it is discontinuous at x = k - 2 and x = k + 2, where k is any arbitrary integer.
The discontinuities at x = k - 2 and x = k + 2 are both removable. That is because the discontinuities occur when the left- and right-hand limits of the function are not equal, and the limits can be made equal by redefining the value of the function at the point of discontinuity.
To solve the problem, set the left- and right-hand limits equal to each other and solve for x.
Left-hand limit: lim x→k-2 f(x) = lim x→k-2 [[x − 2]] = [[k - 2 - 2]] = [[k - 4]]
Right-hand limit: lim x→k+2 f(x) = lim x→k+2 [[x − 2]] = [[k + 2 - 2]] = [[k]]
Equating the two limits, we have [[k - 4]] = [[k]]. Solving for x, we get x = k - 2 and x = k + 2.
Therefore, f(x) = [[x − 2]] is discontinuous at x = k - 2 and x = k + 2. The discontinuities at these points are removable.

Point R is the midponit of XY. If XR = 5x+2 cm and XY= 14x+1 cm , what is the ength of RY in cm ?
Using midpoints, The length of RY is (9x - 1)/2 cm.
What is the midpoint?
A midpoint is a point that is exactly halfway between two other points. In geometry, the midpoint of a line segment is the point on that line segment that is equidistant from both endpoints.
For example, in a line segment AB, the midpoint M is the point on AB that is equidistant from A and B. In other words, the distance from A to M is the same as the distance from M to B. The midpoint M is located at the exact center of line segment AB, and it divides the segment into two equal parts.
The midpoint can also be thought of as the average of the x-coordinates and y-coordinates of the endpoints. For a line segment with endpoints (x1, y1) and (x2, y2), the midpoint has coordinates:
Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
Since R is the midpoint of XY, we know that RX = RY.
We are given that XR = 5x+2 cm and XY = 14x+1 cm.
Thus, RX + RY = XY
Substituting RX = RY, we get:
RY + RY = 14x + 1 - (5x + 2)
Simplifying the right side, we get:
RY + RY = 9x - 1
2RY = 9x - 1
RY = (9x - 1)/2
Therefore, the length of RY in cm is (9x - 1)/2.

x = _____ feet.
The distance from where you launched the ball to the goal is 52.6 feet.
The goal of this problem is to find the distance x from where you launched the ball to the goal. To do this, we can use the trigonometric function tangent. The tangent of an angle in a right triangle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is the distance from where you scored to the sideline (88.1 feet) and the adjacent side is the distance we are trying to find (x).
So, we can set up the equation:
tan(58.828) = 88.1/x
Next, we can cross multiply to get:
x*tan(58.828) = 88.1
Then, we can divide both sides by tan(58.828) to get:
x = 88.1/tan(58.828)
Using the built-in calculator in the right sidebar, we can plug in the values and make sure the setting is on Deg for degrees. This gives us:
x = 88.1/1.6767
Finally, we can round our answer to the nearest tenth of a foot to get:
x = 52.6 feet

The Book Barn is having a sale. All hardback
books are 20% off, and all paperbacks are
10% off. Suppose you buy four paperbacks
that originally cost $9 each and two
hardbacks that originally cost $20. What
percent of the total have you saved? Round to
the nearest percent.
We have saved approximately 15% of the total cost.
What is the process to calculate the percentage saved in a sale?
When items are on sale, they are usually offered at a discounted price. The percentage saved is a measure of the amount that a buyer has saved on the original price of the item. The process to calculate the percentage saved in a sale involves determining the original price, the discounted price, and then using a formula to find the percentage saved.
The formula for the percentage saved is:
Percentage saved = (Amount saved / Original price) x 100%
Calculation of the total amount saved and the percentage saved :
For the paperbacks, the original price is $9 each and we bought four of them, so the total original price is:
$9/book × 4 books = $36
With a 10% discount, the discounted price of each paperback is:
$9/book × 0.10 = $0.90 discount
$9/book - $0.90 discount = $8.10 discounted price
So, the total discounted price for the four paperbacks is:
$8.10/book × 4 books = $32.40
Therefore, we saved:
$36 - $32.40 = $3.60
For the hardbacks, the original price is $20 each and we bought two of them, so the total original price is:
$20/book × 2 books = $40
With a 20% discount, the discounted price of each hardback is:
$20/book × 0.20 = $4 discount
$20/book - $4 discount = $16 discounted price
So, the total discounted price for the two hardbacks is:
$16/book × 2 books = $32
Therefore, we saved:
$40 - $32 = $8
The total original price of all the books is:
$36 + $40 = $76
The total discounted price of all the books is:
$32.40 + $32 = $64.40
Therefore, we saved:
$76 - $64.40 = $11.60
Plugging in the values , we get:
percentage saved = ($11.60 / $76) × 100%
percentage saved ≈ 15%
Therefore, we have saved approximately 15% of the total cost.

You are a quadratic polynomial, specifically an equation of the form ax² + bx + c = 0, where a is not equal to 0, and one of the terms, c, is negative. The polynomial can be written as ax² - dx + c = 0, where d is the coefficient of the positive term.
A polynomial is an expression that consists of a combination of constants, variables, and exponents. A polynomial with three unlike terms is called a trinomial. A 2nd degree polynomial is also known as a quadratic polynomial.
Based on the given information, the polynomial can be written in the form: ax² + bx + c, where a, b, and c are constants, and x is the variable. Since only one of the terms is negative, either a, b, or c must be negative.
There are several possible answers to this question, as there are multiple combinations of constants that can fit the given criteria. Here are three possible answers:
1. 2x² + 3x - 4
2. -x² + 5x + 6
3. 4x² - 2x + 1
All of these polynomials have three unlike terms, are 2nd degree polynomial, and have only one negative term.

The tangent of <S is 8/15
What is Trigonometry?Trigonometry is a discipline of mathematics dealing with specific angle functions and their application to calculations. In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names and acronyms (csc).
Given:
ST = 68
UT = 60
so, SU = √ST² - UT²
= √68² - 60²
= √4624 - 3600
= √1024
= 32
So, Tangent of <S = P/ B
tan S = SU / UT
tan S = 32 / 60
tan S = 8/15

Determine whether the complex number is a solution of the equation. 5-i;x^(2)-10x+26=0
That the complex number 5-i is indeed a solution of the equation [tex]x^2-10x+26=0[/tex].
To determine whether the complex number 5-i is a solution of the equation [tex]x^2-10x+26=0[/tex], we can substitute the value of x with the complex number and see if the equation holds true.
Substituting [tex]x = 5-i[/tex] into the equation:
[tex](5-i)^2 - 10(5-i) + 26 = 0[/tex]
Expanding the squared term:
[tex]25 - 10i + i^2 - 50 + 10i + 26 = 0[/tex]
Simplifying the equation:
[tex]25 - 50 + 26 + i^2 = 0[/tex]
Since[tex]i^2 = -1[/tex], we can substitute that value into the equation:
[tex]25 - 50 + 26 - 1 = 0[/tex]
Simplifying further:
[tex]0 = 0[/tex]
Since the equation holds true, we can conclude that the complex number 5-i is indeed a solution of the equation [tex]x^2-10x+26=0[/tex].
