Reema wants to build a coat rack for the front hallway. The wall is 4 feet long, and the piece of wood she has for the the rack is 28 1/4 inches long. She wants to center the coat rack on the wall. There needs to be an equal amount of space, about 7 or 8 inches, between coat hooks. The first and last hooks should be no less than 1 3/4 inches from either end of the wood. How many hooks should Reema use? What is the distance between the hooks? What is the distance of each hook from the left edge of the wood?

Answers

Reema should use 3 hooks, with a distance of 7 inches between each hook, and each hook will be positioned 5 3/8 inches from the left edge of the wood.

To determine the number of hooks Reema should use, we first need to calculate the available space on the wood for the hooks.

The total length of the wall is 4 feet, which is equivalent to 48 inches. Reema wants to center the coat rack, so she will have an equal amount of space on either side.

Therefore, each side will have (48 - 28 1/4) / 2 = 9 3/8 inches of space.

Next, we need to determine the distance between the hooks.

Reema wants about 7 or 8 inches of space between each hook.

Let's choose 7 inches for consistency.

Since there will be (n - 1) spaces between n hooks, the total space taken by the spaces will be 7 [tex]\times[/tex] (n - 1) inches.

Now, let's subtract the space taken by the spaces from the available space on the wood: 9 3/8 - 7 [tex]\times[/tex] (n - 1) = 9 3/8 - 7n + 7 inches.

Reema wants the first and last hooks to be no less than 1 3/4 inches from either end of the wood.

Therefore, we subtract twice this distance from the remaining space: 9 3/8 - 7n + 7 - 2 [tex]\times[/tex] (1 3/4) = 9 3/8 - 7n + 7 - 3 1/2 inches.

Now we have the expression 9 3/8 - 7n + 7 - 3 1/2 inches representing the remaining space.

We want this value to be greater than or equal to zero, as it should not be negative.

Simplifying the expression, we have 18 7/8 - 7n - 3 1/2 inches ≥ 0.

Now we can solve this inequality to find the range of values for n, the number of hooks.

We can then determine the distance between the hooks by dividing the remaining space by the number of spaces, and the distance of each hook from the left edge of the wood by adding the space taken by the spaces to the distance between the hooks.

∫ (log(1 + x ^ 2))/((x + 1) ^ 2) dx

Answers

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

We have,

To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.

Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:

∫ (log(1 + (u-1)²) / u²) du.

Expanding the numerator, we have:

∫ (log(1 + u² - 2u + 1) / u²) du

= ∫ (log(u² - 2u + 2) / u²) du.

Now, let's split the logarithm using the properties of logarithms:

∫ (log(u² - 2u + 2) - log(u²)) / u² du

= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.

We can simplify the second integral:

∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.

Using the power rule for integration, we can integrate both terms:

∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.

Now, let's focus on the second integral:

∫ (log(u) / u³) du.

This integral does not have a simple closed-form solution in terms of elementary functions.

It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).

Therefore,

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

The expression that could be used to calculate the amount Trina was charged in interest for the billing cycle is  (APR / 365) x 30 days x adjusted balance.

What is the adjusted balance method?

The adjusted balance method is one of the methods for computing the finance charge (interest and other fees) for credit cards.

The adjusted balance is the ending balance determined after adjusting the opening balance with purchases and payments.

Credit card interest method = adjusted balance method

Beginning balance = $780

Purchase = $170

Payment = $210

Adjusted balance, AB = $740 ($780 + $170 - $210)

APR = 17% = 0.17 (17/100)

The interest charged = (APR / 365) x 30 days x adjusted balance

Answer:

m∠1 = 111°: m∠4 = 61°; m∠6 = 141°; m∠7 = 47°

m∠2 = 69°; m∠3 = 119°; m∠5 = 39°; m∠8 = 133°

Step-by-step explanation:

The Polygon Exterior Angle Sum Theorem states the sum of the measures of the exterior angles of a polygon always equals 360°.  

Step 1:  Find x by setting sum of exterior angles equal to 360:

m∠1 + m∠4 + m∠6 + m∠7 = 360

(5x + 11) + (3x + 1) + (8x - 19) + (3x - 13) = 360

(5x + 3x + 8x + 3x) + (11 + 1 - 19 - 13) = 350

19x - 20 = 360

19x = 380

x = 20

Step 2:  Check validity of answer by plugging in 20 for x in the equations representing the measures of angles 1, 4, 6, and 7 and checking that we get 360:

(5(20) + 11) + (3(20) + 1) + (8(20) - 19) + (3(20) - 13) = 360

(100 + 11) + (60 + 1) + (160 - 19) + (60 - 13) = 360

(111 + 61) + (141 + 47) = 360

172 + 188 = 360

360 = 360

Thus, x is indeed 20.

Step 3:  Find the measures of angles 1, 4, 6, and 7 by plugging in 20 for x in the equations representing the measures of the angles.

Plugging in 20 for x in (5x + 11) to find m∠1:

m∠1 = 5(20) + 11

m∠1 = 100 + 11

m∠1 = 111°

Plugging in 20 for x in (3x + 1) to find m∠4:

m∠4 = 3(20) + 1

m∠4 = 60 + 1

m∠4 = 61°

Plugging in 20 for x in (8x - 19) to find m∠6:

m∠6 = 8(20) - 19

m∠6 = 160 - 19

m∠6 = 141°

Plugging in 20 for x in (3x - 13) to find m∠7:

m∠7 = 3(20) - 13

m∠7 = 60 - 13

m∠7 = 47°

In polygons, an interior angle and its corresponding exterior angle are always supplementary and thus the sum of their measures always equals 180°.

Step 4:  Identify the interior angles and their corresponding exterior angles:

∠2 is the interior angle, and its corresponding exterior angle is ∠1.

∠3 is the interior angle, and its corresponding exterior angle is ∠4.

∠5 is the interior angle, and its corresponding exterior angle is ∠6.

∠8 is the interior angle, and its corresponding exterior angle is ∠7.

Step 3:  Find the measures of angles 2, 3, 5, and 8 by subtracting the measures of angles 1, 4, 6, and 7 from 180:

Finding the measure of ∠2:

m∠1 + m∠2 = 180

m∠2 = 180 - m∠1

m∠2 = 180 - 111

m∠2 = 69°

Finding the measure of ∠3:

m∠4 + m∠3 = 180

m∠3 = 180 - m∠4

m∠3 = 180 - 61

m∠3 = 119°

Finding the measure of m∠5:

m∠6 + m∠5 = 180

m∠5 = 180 - m∠6

m∠5 = 180 - 141

m∠5 = 39°

Finding the measure of m∠8:

m∠7 + m∠8 = 180

m∠8 = 180 - m∠7

m∠8 = 180 - 47

m∠8 = 133°

Step 5:  Check validity of answer.

We can find the sum of all the interior angles of a polygon using the formula 180(n-2), where

n is the number of sides.

Since there are 4 sides, the sum of the interior angles of this polygon equals 180 as 180(4-2) = 360

We can check the validity of our answers for Step 3 by seeing if their sum is 360:

m∠2 + m∠3 + m∠5 + m∠8 = 360

(69 + 119) + (39 + 133) = 360

188 + 172 = 360

360 = 360

Thus, we've correctly found the measures of the interior angles.

Answers

The length of segment TU for the intersecting chords is determined as 28.

What is the length of TU?

The length of segment TU is calculated by applying intersecting chord theorem for two chords in a circle as shown below.

From the given diagram we will have the following equation;

UV (UV + TU) = WV (WV + XW)

We know that TU is 3 more than XW;

TU = XW + 3

So our new equation becomes;

26( ( 26 + XW + 3) = 27( 27 + XW)

26(29 + XW) = 27 (27 + XW)

can you find the surface area of the prism of 3.5ft,4.5ft,2ft

Answers

Answer:

Surface Area = 63.5 ft².

Step-by-step explanation:

Length: 3.5 ft

Width: 4.5 ft

Height: 2 ft.

Surface Area = 2(Area of Base) + (Perimeter of Base) × Height

Area of The Base:

       Area of Base = Length × Width

       Area of Base = 3.5 ft × 4.5 ft = 15.75 ft²

Perimeter of The Base:

       Perimeter of Base = 2(Length) + 2(Width)

       Perimeter of Base = 2(3.5 ft) + 2(4.5 ft) = 7 ft + 9 ft = 16 ft

Substitute these values into the surface area formula:

Surface Area = 2(Area of Base) + (Perimeter of Base) × Height

Surface Area = 2(15.75 ft²) + (16 ft) × (2 ft)

Surface Area = 31.5 ft² + 32 ft²

Surface Area = 63.5 ft²

Therefore, the surface area of the given prism with dimensions 3.5 ft, 4.5 ft, and 2 ft is 63.5 ft².

Answer: -3 and -17

Step-by-step explanation:

     When completing the square we add and subtract [tex]\frac{b}{2} ^2[/tex] in the form ax² + bx + c.

[tex]\frac{b}{2} ^2 = \frac{-6}{2} ^2=(-3)^2=9[/tex]

x² - 6x - 8 = (x - __)² - __

(x² - 6x) - 8 = (x - __)² - __

(x² - 6x + 9) - 8 - 9 = (x - __)² - __

(x - 3)² - 17 = (x - __)² - __

A curve C and a straight-line L have respective equations.
y = 2x^2 - 6x + 5
and
2y + x = 4

Find the coordinates of the points of intersection between C and L. Given that the line L is parallel to the line P passing through the points of intersection. Find the equation of line P.

Answers

The equation of line P passing through the points of intersection is y = -1/2x + 2.

To find the coordinates of the points of intersection between curve C and line L, we need to solve the system of equations formed by their respective equations.

The equations are:

C: y = 2x^2 - 6x + 5 ...(1)

L: 2y + x = 4 ...(2)

We can solve this system by substituting the value of y from equation (1) into equation (2):

2(2x^2 - 6x + 5) + x = 4

4x^2 - 12x + 10 + x = 4

4x^2 - 11x + 6 = 0

To solve this quadratic equation, we can factorize it:

(4x - 3)(x - 2) = 0

Setting each factor to zero, we get:

4x - 3 = 0 --> x = 3/4

x - 2 = 0 --> x = 2

Now, substitute these x-values back into equation (1) to find the corresponding y-values:

For x = 3/4:

y = 2(3/4)^2 - 6(3/4) + 5

y = 9/8 - 18/4 + 5

y = 9/8 - 9/2 + 5

y = 9/8 - 36/8 + 40/8

y = 13/8

For x = 2:

y = 2(2)^2 - 6(2) + 5

y = 8 - 12 + 5

y = 1

Therefore, the coordinates of the points of intersection between C and L are (3/4, 13/8) and (2, 1).

Now, we need to find the equation of line P passing through the points of intersection.

We have two points on line P: (3/4, 13/8) and (2, 1).

First, let's find the slope of line P using the formula:

m = (y2 - y1) / (x2 - x1)

m = (1 - 13/8) / (2 - 3/4)

m = (-5/8) / (5/4)

m = -1/2

Now, we have the slope of line P, -1/2. We can use one of the points, let's say (3/4, 13/8), and the slope to find the equation of line P using the point-slope form:

y - y1 = m(x - x1)

Substituting the values:

y - 13/8 = -1/2(x - 3/4)

Simplifying:

y - 13/8 = -1/2x + 3/8

y = -1/2x + 3/8 + 13/8

y = -1/2x + 16/8

y = -1/2x + 2

Therefore, the equation of line P passing through the points of intersection is y = -1/2x + 2.

Determine whether the function is one-to-one. f(x)=-3x+5. Show work.

Answers

One way to show a function is 1-1 is to show that if two outputs are the same, then the inputs had to have been the same as well:

   If f(a) = f(b), then a=b.

If you can show this, you've shown that each output is paired with a unique input, so the function is 1-1.

 

For this function, we'd first start assuming that f(a) = f(b):

              f(a) = f(b)

         -3a+5 = -3b+5

Now we'll solve this for a:

        -3a + 5 = -3b + 5

   -3a + 5 - 5 = -3b + 5 - 5

               -3a = -3b

      -3a ÷ (-3) = -3b  ÷ (-3)

                   a = b

This shows that the only way the outputs are the same is if the inputs are the same, which means each output comes from a unique input, so the function is 1-1.

Step-by-step explanation:

To find the area of the square all you need to do is to find the length of the hypotenuse of the triangles

this will help us find the length of the square if we are given the values of the shorter lengths as shown up

we can calculate the length of the hypotenuse by using the Pythagorean theorem

[tex] \sqrt{a^{2} + b^{2} } = c[/tex]

we are given the sides of the shorter lengths being 5 and 3 we can then substitute them into the formula

let us label the missing length the hypotenuse as x

[tex] \sqrt{ {3}^{2} + {5}^{2} } = x[/tex]

[tex] \sqrt{34} = x[/tex]

[tex]5.83[/tex]

we get that 5.83 rounded to two decimal places is the length of the hypotenuse

we also know that it is the length of the square so

5.83 × 5.83 = Area of Square

34cm² = Area of Square
