By distributive property for real numbers, the expression (- 4 + v + 4 · x) · (- 6) is equivalent to the expression 24 - 6 · v - 24 · x.

In real algebra, distributive property is an algebraic property where a real number is "distributed" on every term of a sum of real numbers. This property is described below:

c · (a + b) = a · c + b · c

Where a, b, c are real numbers.

Now we proceed to use distributive property in the following case. First, write the entire expression:

(- 4 + v + 4 · x) · (- 6)

Second, apply distributive property:

(- 6) · (- 4) + (- 6) · v + (- 6) · (4 · x)

Third, use associative property:

(- 6) · (- 4) + (- 6) · v + [(- 6) · (4)] · x

Fourth, use sign laws and multiply on each term:

The average interest rate would allow you to do so while paying the least amount of money, due to the lower rate compared to the poor.

The equation to model the interest accrued after t years is given as follows:

I(t) = Prt

.

In which the parameters of the equation are explained as follows:

For the average score, the parameters are given as follows:

P = 25000, r = 0.0535, t = 1/12. (as one month = 1/12 of a year).

Hence the interest accrued is of:

I = 25000 x 0.0535 x 1/12

I = 111.46.

For the poor score, the parameters are given as follows:

P = 25000, r = 0,0989, t = 1/12. (as one month = 1/12 of a year).

Hence the interest accrued is of:

I = 25000 x 0.0989 x 1/12

Step-by-step explanation:

The system of inequalities to represent the maximum amount of flooring needed and the maximum amount of money Samuel wants to spend is x + y <= 2000 and 4.50x + 8.25y <= 10000.

Let x be the number of square feet of carpet and y be the number of square feet of hardwood.

The most amount of flooring area he can cover is 2000 square feet. So the first inequality represents the maximum amount of flooring area that Samuel can cover:

x + y <= 2000

The carpet is $4. 50 per square foot and the hardwood is $8. 25 per square foot and Samuel has a budget of $10,000. So the second inequality represents the maximum amount of money that Samuel wants to spend:

4.50x + 8.25y <= 10000

So the system of inequalities is:

x + y <= 2000

4.50x + 8.25y <= 10000

This system represents the possible combinations of carpet and hardwood that Samuel can use while staying within his budget and the maximum amount of flooring area he can cover.

The nonstop trip from Stein to Constance will take 48 minutes.

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Let us suppose the distance between Stein to Constance as d:

Then according to the distance formula, we have:

Distance = Speed * Time

Now, let the velocity of boat be v, and the velocity of water be x.

To go from Stein to Schaffhausen it takes 40 minutes. This is represented as:

d = (v + x) (40) equation 1

To go from Schaffhausen to Stein it takes 60 minutes, this is represeted as:

d = (v - x)(60) equation 2.

Divide the equation 1 and equation 2 wegwt thw following:

3v - 3x = 2v + 2x

v = 5x

Substitute this value in the distance formula:

d = (5x + x) (40)

d = 240x

d/ x = 240

X can be written as v/5, substitute this value in the above equation we have:

d/ v = 48 minutes.

The number of hot cocoas the Ai Mi would be expected to sell with a high temperature of 64 ºF is given as follows:

As the graph of the linear function is given, the most practical way to define the function is using the slope-intercept format, as follows:

y = mx + b.

In which the coefficients are given as follows:

From the graph, when x = 0, y = 111, hence the intercept b is given as follows:

b = 111.

When x increases by 5, from 0 to 5, y decays by four, from 111 to 107, hence the slope m is obtained as follows:

m = -4/5

m = -0.8.

No, the absolute value of equations does not always have two answers

Understanding the absolute value is crucial for mathematicians. We place vertical bars on either side of a number to show its absolute value. On a number line, absolute value refers to distance from zero. A negative number's absolute value is a positive number. A positive number has the same absolute value as another positive number.

There are not always two solutions to an equation's absolute value. An equation involving fundamental values may have one or more solutions, depending on the equation's overall structure and the values that are being entered. For example, whereas the equation |x| = 2x has no solutions, but the equation |x| = 1 has two solutions (x = 1 and x = -1).

Answer:

Step-by-step explanation:

An isosceles triangle with sides of 3/6, 3/6 and an unknown length, and a circle tangent to the two sides with a given radius can be solved using the Pythagorean theorem, trigonometry and the circle area formula.

We know that the triangle is isosceles, so the angle at point B is congruent to angle at point C, and let's call it x. Now we know that angle BAC = 90- x. Since the circle is tangent to the side AB and AC at B and C respectively, we can use the property of tangents that says that the radius of a circle that is tangent to a line is perpendicular to that line, and we can use the triangle formed by the radius, the side and the angle at that point to apply the Pythagorean theorem.

3/6^2 + r^2 = (3/6/sin(x))^2

r^2 = (3/6)^2 (1/sin^2(x) -1)

Now we can use the area of the circle formula A = πr^2, to find the area of the circle that passes through the vertices A, B, and C:

A = π r^2 = π(3/6)^2 (1/sin^2(x) -1)

Using the values of the problem we get

A = π(3/6)^2 (1/sin^2(90- x) -1) = π(3/6)^2 (1/cos^2(x) -1) = π(52^2) = 2701π = 27.01 (D)

Therefore the area of the circle that passes through vertices A, B, and C is 27.01.

Answer:

Step-by-step explanation:

all internal angles in a triangle add to 180 degrees.

77+36=113

180-113=67

we know that the final angle in the triangle is 67 degrees

the left parallel line makes another triangle in the bottom left. we know that one angle is 41 and we just calculated that the other is 67.

41+67=108

180-108=72

so now we know that the small triangle in the bottom left has angles of 41,67 and 72.

all straight lines are 180 degrees, and we just figures out that the left side of the left parallel line is 72 degrees. therefore the other side is 108 degrees.

since they are parallel lines, the left angle of both of them on the bottom line is 72, while the right angle is 108.

this means that x=108 degrees

The surface area per unit volume is increased by a factor of 1000.

1000

The surface area of a cube is 6 times the square of its side length, (A = 6s^2). Since the volume of a cube is the cube of its side length, (V = s^3), the surface area per unit volume is 6/s.

If the volume is increased by a factor of 10, the side length is increased by a factor of 10^(1/3), which is about 3.162. The surface area per unit volume is therefore increased by a factor of 6/3.162, which is about 1,000.

The supplied statement states that the iterated integral after being converted to interpolation is 32/3.

In mathematics, an integral is either a number representing the region beneath a function's graph over a certain interval or just a new function, the reverse of which contains the original mechanism (indefinite integral). To complete the whole, an essential component is required. The term "essential" is almost a synonym in this context. Trigonometric functions of functional and equations are a concept in mathematics. Integral is a derivative of Middle English, Latin integer, and Medieval Latin integralis, each of which mean "making up a whole."

Therefore, the area is,

[tex]R=\left\{(x, y) \mid 0 \leq x \leq 2,0 \leq y \leq \sqrt{2 x-x^2}\right\}[/tex]

So,

[tex]y=\sqrt{2 x-x^2}[/tex]

y² = 2x - x²

x² - 2x + y² = 0

x² - 2x + 1 + y² = 1

(x-1)² + y² = 1

In other words, the area is the middle section of the disk with a radius of 1 and a center at (0,1).

Region R's polar coordinates are

x = r cos∅, y = r sin∅

So,

[tex]y=\sqrt{2 x-x^2}[/tex]

y² = 2x - x²

x² + y² = 2x

r² = 2r cos∅

r = 2 cos∅

The length and breadth of the rectangle are 10m and 6m respectively

The shorter side of a rectangle is called its breadth (width) and the longer side is the length.

The area of a rectangle = L×B

and the perimeter = 2(L+B)

where L is the length and B is the breadth

therefore 60 = LB, and B = 60/L

and 32 = 2(L+B)

substitute 60/L for B

32 = 2(L+60/L)

divide both sides by 2

16 = L+60/L

16 =( L²+60)/L

therefore L² +60 = 16L

L² -16L +60= 0

L²-10L-6L +60 = 0

L(L-10)-6(L-10) = 0

L-10 = 0 or L-6 = 0

therefore L = 10 or 6

when L is 10m then B = 60/10 = 6m

when L is 6m then B = 60/6 = 10m

Since the longer side is length then L = 10m and B = 6m

therefore the length and breadth of the rectangle are 10m and 6m respectively.
