Answer:

  $9.34 per square foot

Step-by-step explanation:

You want the cost per square foot of a 36 foot square building that costs $12,099.

The cost per square foot is found by dividing the cost by the number of square feet. That area is found as the square of the side length:

  A = s²

  A = (36 ft)² = 1296 ft²

Then the cost is ...

  cost per square foot = ($12099)/(1296 ft²) ≈ $9.34/ft²

The cost of the building is about $9.34 per square foot.

2 3/4 cups is equivalent to 1 3/8 pints as a mixed number.

There are 2 cups in a pint. To convert 2 3/4 cups into pints, we can follow these steps:

Convert the whole number part of the mixed number to pints by dividing by 2.

Convert the fractional part of the mixed number to cups, then divide by 2 to get the corresponding pints.

Add the two results together to get the total in pints as a mixed number.

So, let's apply these steps to 2 3/4 cups:

The whole number part is 2, so 2 cups = 1 pint.

The fractional part is 3/4 cups, which is equivalent to 3/4 ÷ 2 = 3/8 pints.

Adding the two results, we get:

1 pint (from the whole number part) + 3/8 pint (from the fractional part) = 1 3/8 pints.

Answer:

Each small box has 24/17 beads.

Step-by-step explanation:

Let's call the number of beads in each small box "s" and the number of beads in each large box "l".

We know that there are 14 small boxes, so the total number of beads in the small boxes is 14s. We also know that there are 3 large boxes, so the total number of beads in the large boxes is 3l.

From the problem, we know that there are 4 more beads in each large box than in each small box, so we can write:

l = s + 4

We also know that 7/9 of the total number of beads were packed in the small boxes, so we can write:

14s + 3l = 7/9(total number of beads)

We can simplify this expression by substituting l = s + 4:

14s + 3(s + 4) = 7/9(total number of beads)

Expanding and simplifying:

17s + 12 = 7/9(total number of beads)

Now, we need one more equation to solve for s. We know that the total number of beads is equal to the sum of the beads in the small and large boxes:

total number of beads = 14s + 3(s + 4)

Simplifying:

total number of beads = 17s + 12

Now we have two equations that we can use to solve for s:

17s + 12 = 7/9(total number of beads)

total number of beads = 17s + 12

We don't know the total number of beads, but we do know that it is a multiple of both 14 and 3 (since there are 14 small boxes and 3 large boxes). The smallest multiple of both 14 and 3 is 42, so let's assume that the total number of beads is 42x, where x is some number.

Substituting 42x for "total number of beads" in the two equations:

17s + 12 = 7/9(42x)

42x = 17s + 12

Simplifying:

153s + 108 = 98x

42x = 17s + 12

Now we have two equations and two unknowns (s and x). We can solve for s in terms of x by isolating s in the second equation:

17s = 42x - 12

s = (42x - 12)/17

We can substitute this expression for s into the first equation:

17((42x - 12)/17) + 12 = 7/9(42x)

Simplifying:

42x - 12 + 12 = 14x

28x = 24

x = 24/28 = 0.857

Now we know that the total number of beads is:

42x = 42(0.857) = 36

And we know that each small box has:

s = (42x - 12)/17 = (36 - 12)/17 = 24/17

So each small box has 24/17 beads.

The equation of the tangent line at (1,1) is given as follows:

y - 1 = -0.25(x - 1).

The curve for this problem is given as follows:

x² - y² = 2x + y + xy - 4.

Applying implicit differentiation, we obtain the slope of the tangent line, as follows:

2x - 2y(dy/dx) = 2 + (dy/dx) + x(dy/dx) + y

(dy/dx)(1 + x + 2y) = 2x - 2 - y

m = (2x - 2 - y)/(1 + x + 2y).

At x = 1 and y = 1, the slope is given as follows:

m = (2 - 2 - 1)/(1 + 1 + 2)

m = -0.25.

Hence the point-slope equation is given as follows:

Answer: The market demand is x = 750.

Step-by-step explanation:

Answer: The market demand is x = 750.

Explanation:

To find the market demand, we need to set the demand function equal to the supply function and solve for x:

d(x) = s(x)

600 − 0.8x = 0.4x

Combining like terms, we get:

600 = 1.2x

Dividing both sides by 1.2, we get:

x = 500

However, we need to find the positive value of x. Since x represents the quantity demanded, it cannot be negative.

Substituting x = 500 into both the demand and supply functions, we find that:

d(500) = 600 - 0.8(500) = 200

s(500) = 0.4(500) = 200

Since d(500) = s(500), x = 500 is not the market demand.

Substituting x = 750 into both the demand and supply functions, we find that:

d(750) = 600 - 0.8(750) = 0

s(750) = 0.4(750) = 300

Since d(750) = s(750), x = 750 is the market demand.

Therefore, the market demand is x = 750.

Step-by-step explanation:

To find the partial sum for the sequence

[tex]\large \boxed{\mathrm{ \ 0, \ -1, \ -3, \ -6, \ -10,}}[/tex]

We first notice that the first term is

[tex]\large \boxed{\mathrm{0}}[/tex],

And each subsequent term is the sum of the previous term and the next integer in the sequence starting with [tex]-1.[/tex] Therefore, we can use the formula for the sum of an arithmetic series to find the partial sum S14:

S14 = 14/2 * (2(0) + (14-1)(-1+0)/2) = 14/2 * (13/2 * -1) = -91

Therefore, the partial sum for the sequence up to the [tex]14th[/tex] term is [tex]-91.[/tex]

Answer:

[tex]91[/tex]

Step-by-step explanation:

The partial sum of a sequence is the sum of a certain number of terms in the sequence. For the given sequence

{0, −1, −3, −6, −10, ...},

The nth term can be represented as Tn = n(n-1)/2. This means that the partial sum of the first 14 terms of the sequence, denoted by S14, can be calculated by adding up the first 14 terms using the formula: S14 = 0 + (-1) + (-3) + (-6) + (-10) + ... + T14.

Simplifying this expression using the formula for Tn, We get S14 = 91. Therefore, the partial sum for the given sequence up to the 14th term is equal to 91.

Answer: The Correct answer is E (2,pie/6)

Step-by-step explanation:

To find the polar coordinates of a point given its Cartesian coordinates (x, y), we can use the following formulas:

r = √(x^2 + y^2)

θ = atan2(y, x)

where r is the radial distance from the origin to the point, and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin and the point.

Given the Cartesian coordinates (x, y) = (√3, 1), we can plug these values into the formulas to find the polar coordinates:

r = √(√3^2 + 1^2) = √(3 + 1) = 2

θ = atan2(1, √3)

Using a calculator, we can find that θ is approximately 0.5236 radians.

So, the polar coordinates of the point (√3, 1) are (r, θ) = (2, 0.5236 radians).

Here's how to graph the piecewise function:

First, we graph the function for the first interval, which is f(x) = 3x - 5 when x ≤ -1. This is a straight line with a slope of 3 and a y-intercept of -5. Since this interval includes -1, we draw a closed circle at x = -1 to indicate that it is included in the interval. The line is decreasing as x increases.

Next, we graph the function for the second interval, which is f(x) = -2x + 3 when -1 < x < 4. This is also a straight line, but with a slope of -2 and a y-intercept of 3. Since this interval does not include -1, we draw an open circle at x = -1 to indicate that it is not included in the interval. We also draw an open circle at x = 4 to indicate that it is not included in the interval. The line is increasing as x increases.

Finally, we graph the function for the third interval, which is f(x) = 2 when x ≥ 4. This is a horizontal line at y = 2. Since this interval includes 4, we draw a closed circle at x = 4 to indicate that it is included in the interval.

When we put all three intervals together, we get a graph that looks like this:

Answer:131290

Answer:

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's check if the triangle with sides of 30, 64, and 90 is a right triangle:

30^2 + 64^2 = 900 + 4096 = 4996

90^2 = 8100

Since 4996 is less than 8100, the triangle is not a right triangle.

In an acute triangle, all angles are less than 90 degrees. In an obtuse triangle, one angle is greater than 90 degrees.

To determine if the triangle is acute or obtuse, we need to find the largest side. The largest side is 90. Let's find the sum of the squares of the other two sides:

30^2 + 64^2 = 900 + 4096 = 4996

Since 4996 is less than 90^2, the triangle is acute.

Therefore, the triangle with sides of 30, 64, and 90 is an acute triangle.

the triangle is obtuse

Step-by-step explanation:

[tex] {90}^{2} = 8100[/tex]

[tex] {30}^{2} + {64}^{2} = 4996[/tex]

[tex] {30}^{2} + {60}^{2} < {90}^{2} [/tex]

triangle is obtuse because the square of the largest is greater than the sum of the square of the other 2 sides

The second job offer is better by $21,840.

We have :

An employee is considering two job offers.

First offer: $57,000 yearly salary with an 8% matching 401k

Second offer: $63,000 yearly salary with a 4% matching 401k

Let's calculate the total value of the second offer after 4 years:

Yearly salary is : $63,000

Total gross income after 4 years: $63,000 x 4 = $252,000

The company matches 5% of the employee's salary.

So, the employee contributes 5% of $63,000 = $3,150 per year

After 4 years,

Company matches: $3,150 x 4 = $12,600

Employee contributions: $3,150 x 4 = $12,600

Total 401k contributions: $12,600 + $12,600 = $25,200

The total value of the second offer after 4 years is:

Total value: $252,000 + $25,200 = $277,200

Now, let's compare this to the total value of the first offer, which is : $255,360.

Therefore, the second job offer is better by:

$277,200 - $255,360 = $21,840

The Galois group of f over R is isomorphic to the symmetric group S4. The given statement "Each intermediate field of F/Q is a Galois extension of Q." is true because f is separable.

The roots of f are given by

x = ±(√(5) + √(2)), ±(√(5) - √(2))

Let φ be the automorphism defined by

φ(√(5) + √(2)) = √(5) + i√(2)

φ(√(5) - √(2)) = √(5) - i√(2)

φ(-√(5) + √(2)) = -√(5) - i√(2)

φ(-√(5) - √(2)) = -√(5) + i√(2)

where i is the imaginary unit. Then φ has order four since φ⁴ is the identity automorphism. Let σ be the automorphism defined by

σ(√(5) + √(2)) = -√(5) + √(2)

σ(√(5) - √(2)) = √(5) - √(2)

σ(-√(5) + √(2)) = -√(5) - √(2)

σ(-√(5) - √(2)) = √(5) + √(2)

Then σ has order two since σ² is the identity automorphism. It can be shown that the Galois group of f over Q is generated by φ and σ. Since φ has order four and σ has order two, the Galois group is a non-abelian group of order eight.

To prove or disprove that each intermediate field of F/Q is a Galois extension of Q, we need to show that each intermediate field is a splitting field of a separable polynomial over Q. Since F is the splitting field of f over Q, any intermediate field of F/Q is also a splitting field of f over Q. Since f is separable (its roots are distinct), every intermediate field of F/Q is a Galois extension of Q, and hence a splitting field of a separable polynomial over Q. Therefore, the statement is true.

Answer:

The circumference of a circle is given by the formula "C = pi x d" where "d" is the diameter and "pi" is the mathematical constant with an approximate value of 3.14.

In this problem, the diameter of the bicycle wheel is 60 centimeters, so its circumference is:

C = pi x d = 3.14 x 60 = 188.4 centimeters

When the wheel makes one revolution, it travels one circumference distance. Therefore, when the wheel makes 35 revolutions, it will travel:

distance = 35 x circumference = 35 x 188.4 = 6584 centimeters

We can convert centimeters to meters by dividing the distance by 100:

distance = 6584 ÷ 100 = 65.84 meters

Therefore, the wheel travels 65.84 meters when it makes 35 revolutions.
