For this case we have the following expression:

[tex]\frac {10p-5} {5 + 3 (p-1)}[/tex]

We must find the value of the expression when c[tex]p = 2[/tex].

Substituting the value of "p" we have:

[tex]\frac {10 (2) -5} {5 + 3 ((2) -1)} =\\\frac {20-5} {5 + 3 (1)} =\\\frac {20-5} {5 + 3} =\\\frac {15} {8}[/tex]

The area of the triangle is 16. 

You can find this by plotting each of the points and drawing the triangle. You can then use the distance formula to determine each side length. The rectangle will be 2 on one side and 4 on the other. When multiplied together, it will give you the above answer

The coordinates of the midpoints for each side are (2.5, 5.5) , (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

And, yes, the midpoints are the vertices of a rectangle, as its opposite sides are the same in length.

Use the formula for the midpoint of two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are,

[tex][\dfrac{(x_1 + x_2)}{2} , \dfrac{(y_1 + y_2)}{2} ][/tex]

Given that,

Vertices of the rectangle are (0, 8), (5, 3), (4, 2), and (- 1, 7).

Hence, the coordinates of the midpoints for each side are calculated by using the above formula,

The midpoint of two points (0, 8) and (5, 3) are,

[tex](\dfrac{(0 + 5)}{2} , \dfrac{(8 + 3)}{2} )[/tex]

[tex](2.5, 5.5)[/tex]

The midpoint of two points (5, 3) and (4, 2) are,

[tex](\dfrac{(5 + 4)}{2} , \dfrac{(3 + 2)}{2} )[/tex]

[tex](4.5, 2.5)[/tex]

The midpoint of two points (4, 2) and (-1, 7) are,

[tex](\dfrac{(4 - 1)}{2} , \dfrac{(2 + 7)}{2} )[/tex]

[tex](1.5, 4.5)[/tex]

The midpoint of two points (-1, 7) and (0, 8) are,

[tex](\dfrac{(-1 + 0)}{2} , \dfrac{(8 + 7)}{2} )[/tex]

[tex](-0.5, 7.5)[/tex]

Therefore, the coordinates of the midpoints for each side are (2.5, 5.5) , (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

When the coordinates of vertices are rectangular then opposite sides are equal to each other.

So, we can check the length of each side of the coordinates of the midpoints (2.5, 5.5), (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

Used the distance formula,

The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is,

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

So, The distance between the two points [tex](2.5, 5.5)[/tex] and [tex](4.5, 2.5)[/tex],

[tex]d = \sqrt{(4.5- 2.5)^2 + (2.5 - 5.5)^2}[/tex]

[tex]d = \sqrt{4 + 9}[/tex]

[tex]d = \sqrt{13}[/tex]

The distance between the two points [tex](4.5, 2.5)[/tex] and [tex](1.5, 4.5)[/tex],

[tex]d = \sqrt{(4.5- 1.5)^2 + (2.5 - 4.5)^2}[/tex]

[tex]d = \sqrt{9 + 4}[/tex]

[tex]d = \sqrt{13}[/tex]

The distance between the two points [tex](1.5, 4.5)[/tex] and [tex](-0.5, 7.5)[/tex]

[tex]d = \sqrt{(1.5+ 0.5)^2 + (7.5 - 4.5)^2}[/tex]

[tex]d = \sqrt{4 + 9}[/tex]

[tex]d = \sqrt{13}[/tex]

The distance between the two points[tex](-0.5, 7.5)[/tex] and [tex](2.5, 5.5)[/tex]

[tex]d = \sqrt{(2.5+ 0.5)^2 + (7.5 - 5.5)^2}[/tex]

[tex]d = \sqrt{9 + 4}[/tex]

[tex]d = \sqrt{13}[/tex]

Clearly, All the lengths of each side of the coordinates of the midpoints (2.5, 5.5), (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5) are the same.

Hence, it forms a rectangle, as its opposite sides are also the same in length.

Final answer:

The sum of −0.7 and ⅔ is −0.45 when the fraction is simplified to 0.25 and then added to −0.7.

Explanation:

Fractions are used extensively in mathematics, particularly in arithmetic, algebra, geometry, and calculus, as well as in everyday situations such as cooking, measurements, and financial calculations. They provide a convenient way to express quantities that are not whole numbers and to perform operations such as addition, subtraction, multiplication, and division.

The student is asking for the sum of -0.7 and the fraction 2/8. To find the answer, first simplify the fraction 2/8, which can be reduced to 1/4. Now, convert 1/4 into decimal form, which is 0.25. Next, add this decimal to -0.7 to find the sum:

-0.7 + 0.25 = -0.45.

Therefore, the exact decimal for the expression −0.7 + ⅔ is -0.45.

Step-by-step explanation:

Answer:

Step-by-step explanation:

-x is common to all three terms.  Thus, -x^3-2x^2-3x = -x(x^2 + 2x + 3).

Use the quadratic formula to find the roots (and thus the factors) of

x^2 + 2x + 3:  a = 1; b = 2; c = 3.

Thus, the discriminant is b^2-4ac, or 4 - 4(1)(3), or -8.

Because this discriminant is negative, x^2 + 2x + 3 has two complex, unequal roots.  They are:

Answer:

The correct answer is option A. 26°

Step-by-step explanation:

From the figure we can see that,

OM ⊥ NL

Therefore m<N = m<L

To find the value of x

m<N = m<L

7x  + 8 = 9x -8

9x - 7x = 8 + 8

2x = 16

x = 8

To find the value of m<OML

x = 8

m<L = 9x - 8

= 9*8 - 8 = 72 - 8 = 64

m<OML = 180 - (<L + <O)

 = 180 - ( 64 + 90)

 = 26°

Therefore the correct answer is option A. 26°

You could use a ruler, think about how you want the polygon inside of the circle or how you want the circle to surround the polygon. When you use a ruler, make sure your co-ordinates inside of the circle are correct though before drawing the line.

I hope this info helps! :3

To construct a regular polygon inside a circle, divide the circle into "n" equal sectors using "n" radii, where "n" represents the number of sides in the polygon. Connect the center of the circle to each of the marked points on the circumference to create the regular polygon.

Determine the Circle: Start by drawing the given circle with a compass, and label its center as "O."

Select the Number of Sides: Decide on the number of sides for the regular polygon. Let's assume "n" as the number of sides.

Construct Diameter: Draw a diameter of the circle passing through the center "O," using a straightedge.

Construct Central Angle: To create a regular polygon with "n" sides, divide the circle into "n" equal sectors by constructing "n" radii (lines from the center to the circumference) evenly spaced around the circle. Each of these radii forms a central angle of 360°/n.

Find Vertices: On the circumference of the circle, mark "n" points (labeled A₁, A₂, A₃, ..., Aₙ) evenly spaced. These points will serve as the vertices of the regular polygon.

Connect Vertices: Use a straightedge to draw lines connecting the center "O" of the circle to each of the marked points (A₁, A₂, ..., Aₙ).

Construct Regular Polygon: The polygon with vertices A₁, A₂, ..., Aₙ, and center "O" is the regular polygon inscribed inside the circle.

Answer:

Production of  2800  juice boxes is the break even point.

Step-by-step explanation:

Break-even point is the point where profit is zero and number of manufactured goods are all sold

Let number of juice boxes be y

charges of local store for 1 juice box= $0.65

charges of local store for y juice box=$0.65y

Factory cost of y juices boxes= $1400 + $0.15y

Assuming all juice boxes manufactured can be sold, to find the break-even point

charges of local store for y juice box= Factory cost of y juices boxes

$0.65y=$1400 + $0.15y

$0.65y-$0.15y= $1400

$0.50y=$1400

y= 1400/0.5

y=2800

hence production of  2800  juice boxes is the break even point!

To determine (f(a+h) - f(a)) for f(x) = x² + 5x, we substitute a+h and a into the function, expand, and subtract to ultimately simplify to 2ah + h² + 5h.

To determine (f(a+h) - f(a)) for f(x) = x² + 5x and simplify, we need to substitute x with a+h and a into the function separately and then find the difference. Here are the steps:

Substitute a+h into f(x) to get f(a+h) = (a+h)² + 5(a+h).

Expand the equation: f(a+h) = a² + 2ah + h² + 5a + 5h.

Substitute a into f(x) to get f(a) = a² + 5a.

Find the difference: (f(a+h) - f(a)) = (a² + 2ah + h² + 5a + 5h) - (a² + 5a).

Simplify the expression: (f(a+h) - f(a)) = 2ah + h² + 5h.

The answer is:

To find the resultant expression, we need to apply the distributive property.

It  can be defined by the following way:

Also, we need to remember how to add like terms: The like terms are the terms that share the same variable and exponent, for example:

[tex]x+x+x^{2}=2x+x^{2}[/tex]

We were able to add only the two first terms since they were like terms (they share the same variable and the same exponent)

So , we are given the expression:

[tex](x+y)(x^{2}-xy+y^{2})[/tex]

Then, applying the distributive property, we have:

[tex](x+y)(x^{2}-xy+y^{2})=x*x^{2}-x*xy+x*y^{2}+y*x^{2}-y*xy+y*y^{2}\\\\x*x^{2}-x*xy+x*y^{2}+y*x^{2}-y*xy+y*y^{2}=x^{3}-x^{2}y+xy^{2}+yx^{2}-xy^{2}+y^{3}\\\\x^{3}-x^{2}y+xy^{2}+yx^{2}-xy^{2}+y^{3}=x^{3}+y^{3}[/tex]

What question do you need answered?

Answer:

Option A.

Step-by-step explanation:

Anastasia worked for = 7 hours per day

Number of weeks she worked = 52 weeks

Number of hours she worked = 7×52

= 364 hours

Per hour earning of Anastasia = $20

Total earning of Anastasia = 364×20

= $7280

Let the monthly expenses of Anastasia = $x

Then total expenses = $12x

At the end of the year total saving = Total earning - Total expenses

= $7280 - 12x

Since she saved $2000 in a year therefore, expression that represents the savings will be

2000 = 7280 - 12x

12x = 7280 - 2000

12x = 5280

= 1000 + [tex]\frac{1}{3}[(3.14)(25)(7)][/tex]

= 1000 + 183.17

= 1183.17 cubic inch

Total volume of 12 wooden pedestals = 12 × 1183.17 = 14198 cubic inch

Since charges of the wood is $0.08 per cubic inch

So total charges for pedestal will be = 0.08 × 14198 = $1135.84 ≈ $1136

12^2 = 144

63^= 3969

A^2 + B^2 = C^2

81 + 144 = 225

so these numbers do not make a right triangle

Final answer:

The numbers square root of 63, 9, and 12 do make a right triangle as their squares satisfy the Pythagorean theorem. The sum of the squares of 9 and square root of 63 equals the square of 12, which validates that we have a right triangle.

Explanation:

To determine if the numbers square root of 63, 9, and 12 make a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides must be equal to the square of the longest side (the hypotenuse). Let's calculate the squares of each provided number:

Since the longest side here must be 12 (as it is the largest number), the Pythagorean theorem for these numbers would be as follows:
81 + 63 = 144?

That simplifies to:
144 = 144?

This is a true statement, which means that these numbers do indeed represent the sides of a right triangle.

ANSWER

[tex]\theta = 0 ,\frac{7\pi}{6} ,\frac{11\pi}{6 } [/tex]

EXPLANATION

We want to solve

[tex] \sin( \theta) + 1 = \cos(2 \theta) [/tex]

on the interval

[tex]0 \leqslant \theta \: < \: 2\pi[/tex]

Use the double angle identity to obtain:

[tex] \sin( \theta) + 1 = 1 - 2\sin ^{2} \theta[/tex]

Simplify to get;

[tex] 2\sin ^{2} \theta + \sin( \theta) + 1 - 1 = 0[/tex]

[tex]2\sin ^{2} \theta + \sin( \theta) = 0[/tex]

Factorize to obtain:

[tex]\sin \theta (2\sin \theta + 1) = 0[/tex]

Either

[tex]\sin \theta = 0[/tex]

This gives us

[tex] \theta = 0[/tex]

on the given interval.

Or

[tex]2\sin \theta + 1= 0[/tex]

[tex]\sin \theta = - \frac{1}{2} [/tex]

This gives us

[tex]\theta = \frac{7\pi}{6} ,\frac{11\pi}{6 } [/tex]

Therefore the solutions within the interval are:

[tex]\theta = 0 ,\frac{7\pi}{6} ,\frac{11\pi}{6 } [/tex]

Answer:

[tex]f(g)=25g[/tex]

Step-by-step explanation:

Let [tex]g[/tex] be the number of gallons so [tex]f(g)[/tex] is the number of miles traveled per [tex]g[/tex] gallons.

We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by [tex]g[/tex], his car will travel a total distance of 25g (where g is the number of gallons.

We also know that the total distance is given by [tex]f(g)[/tex], so we can put the two expressions together to get our function:

[tex]f(g)=25g[/tex]

Let's check:

- If he uses 1 gallon (g=1), so

[tex]f(1)=25(1)[/tex]

[tex]f(1)=25[/tex] miles

He will travel 25 miles with one gallon.

- If he uses 2 gallons (g=2), so

[tex]f(2)=25(2)[/tex]

[tex]f(2)=50[/tex]

He will travel 50 miles with two gallon.
