Which expression would be easier to simplify if you used the associative property to change the grouping?
Answers
The expression that would be easier to simplify if you used the associative property to change the grouping is D. (160 + 40) + 27.
What is the associative property?The associative property of some binary operations in mathematics means that rearranging the parentheses in an expression will not change the result. Associativity is a valid rule of replacement for expressions in logical proofs in propositional logic.
This law simply states that when adding and multiplying numbers, you can change the grouping of the numbers in the problem and the answer will not change.
Addition and multiplication are both affected by the associative property. The reason for this is that you are combining numbers to get a total in both of these operations. You are combining values with addition. It makes no difference how you group these to put them together. The associative property of addition states that the addends can be grouped in various ways without changing the outcome.
In this case, (160 + 40) + 27 can simply be (40 + 160) + 27.

Given that ΔABC and ΔCBD are right triangles
Therefore, one angle of both triangle is of 90°
So, ∠B is same in both triangles. Hence, by suing the Angle-Angle theorem rule we can conclude that both ΔABC and ΔCBD are similar.
Consequently, ∠A is same in both triangles. Hence, by suing the Angle-Angle theorem rule we can conclude that both ΔABC and ΔCBD are similar.
Similarly, When two triangles are similar then their corresponding angles are equal and their corresponding sides are also equal.
Therefore , the two proportions can be rewritten as
a² = cf ( equation 1 )
b² = ce ( equation 2 )
By adding b² on both side of equation 1 then we can write equation 1 as

Choose an expression equivalent to 2x2-12x+23
Group of answer choices
2(x+23)2-1
2(x+3)2+14
2(x-3)2+5
2(x-3)2+13
Answers
Answer: 2(x-3)2+13
To find the equivalent expression, we can use the property of square roots that says that the square of the difference of two numbers is the difference of the squares of the numbers. This property is given by the following equation:
(a-b)2 = a2-2ab+b2
In this case, the expression we are trying to simplify is 2x2-12x+23, which we can rewrite using the property of square roots as follows:
2x2-12x+23 = 2(x2-6x+11)
Then, we can use the property of square roots that says that the square of the difference of two numbers is the difference of the squares of the numbers to simplify the expression as follows:
2x2-12x+23 = 2(x2-6x+11) = 2(x2-6x+36-25)
Finally, we can use the commutative property of addition and the associative property of addition to simplify the expression even further:
2x2-12x+23 = 2(x2-6x+36-25) = 2((x-3)2+11) = 2(x-3)2+22
Therefore, the equivalent expression to 2x2-12x+23 is 2(x-3)2+13. This means that the correct answer is 2(x-3)2+13.

What is triangle?
Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.
Given:
dx / dt = 2 feet / sec
We have to find dA/dt when x = 7.
Since,
Area = 1/2 x (xy)
A = 1/2 x (xy)
Differentiating both sides with respect to t
[tex]\frac{dA}{dt} = \frac{1}{2}(\frac{dx}{dt}y+\frac{dy}{dt}x)\\[/tex] ..(1)
We have,
x^2 + y^2 = 25^2
plug x = 7
⇒ y = √(25^2 - 7^2)
y = √(625 - 49)
y = √576
y = 24
Now plug x = 7, y = 24, dx/dt = 2 and dy/dt = -7/12 in equation (1)
[tex]\frac{dA}{dt} = \frac{1}{2} (2(24) + (-\frac{7}{12})(7)) \\ \frac{dA}{dt} = \frac{527}{24} ft^2/sec[/tex]

what is the greatest possible area of a triangular region with one vertex at the center of a circle of radius 1 and the other two vertices on the circle?
Answers
The greatest possible area of the triangle be
Area = 1/2 sq. units.
Given, a triangular region with one vertex at the center of a circle of radius 1 and the other two vertices on the circle.
we have to find the greatest possible area of the given triangular region.
Let the height of the triangle be, h and the base of the triangle be b.
using Pythagoras theorem, we get
1² = h² + (b/2)²
1 = h² + b²/4
h² = 1 - b²/4
Now, the area of the triangle be,
A = 1/2×b×h
squaring both the sides,
A² = 1/4×b²×h²
A² = 1/4×b²×(1 - b²/4)
A² = 1/4×b²×(4 - b²)/4
A² = 1/16×b²(4 - b²)
On differentiating, we get
2AA' = 1/16×[2b(4 - b²) -2b³]
2AA' = 1/8×[b(4 - b²) -b³]
2AA' = 1/8×(4b - 2b³)
2AA' = 1/4×(2b - b³)
On equating with zero, we get
b(2 - b²) = 0
b = √2
so, h = 1/√2
Therefore, the greatest possible area of the triangle be
A = 1/2 sq. units.
Hence, the greatest possible area of the triangle be
A = 1/2 sq. units.

Answers
In order to complete the square for the given equation x^2+16x=18, the number added to both sides is 64.
Complete the square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial. To complete the square, add or subtract the same value to both sides. In this case, add the square of half the coefficient of the x -term, (b/2)^2 to both sides of the equation. Hence, the number to add would be (16/2)^2 = 64.

Answers
The pool's water is changing height at a pace of 0.283 feet per minute.
Given,
Right circular cylinder shaped pool.
The radius of the pool = 3 feet
The height of the pool = 8 feet
Imagine that 6 cubic feet of water per minute is continuously being poured into a swimming pool in the shape of a right circular cylinder.
We have to find the rate of change of the height of the water in the pool when the depth of the water in the pool is 6 feet;
Here,
Due to the swimming pool's right circular cylinder shape, its volume equals;
V(c) = π × r² ×h
Where r is the radius of the base and h the height
We take differentiation on both sides of the equation to get:
dV/dt = π × r² × dh/dt
Since the pool is a right circular cylinder and dV/dt is constant at 6 ft3/min, the rate of change in water height in the pool is independent of water height.
Then:
6 = π × r² × dh/dt
dh/dt = 6 / π × 3²
dh/dt = 8/113,04
dh/dt = 0.283 ft/min
Therefore,

Answers
If a set of scores does have a standard deviation of 4 and just a mean of 54, the score that is 1 standard deviation well below mean is 50.
Explain the term standard deviation?The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a large or low standard deviation indicates that the variables are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean.For the given values-
Mean = 54
standard deviation = 4
1 value below the standard deviation is;

How to calculate area from normal distribution?
μ = population mean = 22
σ = standard deviation = 7
The area from normal distribution can be calculated using z test or normal distribution formula.
a) The area to the left of 25 is
P(x ≤ 25) = P(z ≤ [tex]\frac{x-\mu}{\sigma}[/tex])
= P(z ≤ [tex]\frac{25-22}{7}[/tex])
= P(z ≤ 0.43)
using z table and we get,
= 0.6664
b) The area to the left of 17 is
P(x ≤ 17) = P(z ≤ [tex]\frac{x-\mu}{\sigma}[/tex])
= P(z ≤ [tex]\frac{17-22}{7}[/tex])
= P(z ≤ -0.71)
using z table and we get,
= 0.2389
c) The area to the right of 22 is
P(x > 22) = 1 - P(z ≤ [tex]\frac{x-\mu}{\sigma}[/tex])
= 1 - P(z ≤ [tex]\frac{22-22}{7}[/tex])
= 1 - P(z ≤ 0.00)
using z table and we get,
= 1 - 0.5
= 0.5000
d) The area to the right of 27 is
P(x > 22) = 1 - P(z ≤ [tex]\frac{x-\mu}{\sigma}[/tex])
= 1 - P(z ≤ [tex]\frac{27-22}{7}[/tex])
= 1 - P(z ≤ 0.71)
using z table and we get,
= 1 - 0.7611
= 0.2389
e) The area between 17 and 30 is
P(17 ≤ x ≤ 22) = P([tex]\frac{x-\mu}{\sigma}[/tex] ≤ z ≤ [tex]\frac{x-\mu}{\sigma}[/tex])
= P([tex]\frac{17-22}{7}[/tex] ≤ z ≤ [tex]\frac{30-22}{7}[/tex])
= P(-0.71 ≤ z ≤ 1.14)
= P(z ≤ 1.14) - P(z ≤ -0.71)
using z table and we get,
= 0.8729 - 0.2389
= 0.6340
Thus, the area is 0.6664 for area in the left of 25, the area is 0.2389 for area in the left of 17, the area is 0.5 for area in the right of 22, the area is 0.2389 for area in the right of 27, and the area is 0.634 for area between 17 and 30.

A rectangular pasture does have a 1200 foot circumference. The width of the meadow is 200 feet wider than its length.Let the pasture's rectangular length be l feet.
Given that the rectangular pasture's length being 200 feet longer than its breadth, its width must be w = l200 feet.
The pasture's boundary is;
2(l + w) = 1200
2(l + l - 200) = 1200
2l - 200 = 600
l = 400 feet
Width; w = l - 200
w = 400 - 200 = 200 feet
Rectangular area;
A = l x w
A = 400 x 200
A = 80,000 ft²
Thus, the area of the rectangular pasture is found to be 80,000 ft².

Two parallel lines are crossed by a transversal. Horizontal and parallel lines y and z are cut by transversal x. At the intersection of lines y and x, the top right angle is (2 k + 11) degrees. At the intersection of lines z and x, the bottom left angle is 131 degrees. What is the value of k?.
Answers
The number k is equal to 60 when the top right angle at the intersection of the lines y and x is (2 k + 11) degrees and the bottom left angle is 131 degrees.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. A mathematical expression is a sentence that includes numbers, variables, or both. The equal sign is never used in expressions. A mathematical statement stating the equality of two expressions is known as an equation.
Here,
Those two angles have the same measure. so you have,
2k+11=131
22k=120
k=60
The value of k where at the intersection of lines y and x, the top right angle is (2 k + 11) degrees and at the intersection of lines z and x, the bottom left angle is 131 degrees is 60.
