Parabola intersects x-axis at two points: (-5,0) and (-4,0)

What does a parabola actually mean?

Each point on a parabola with a U-shape is equally spaced from both the focus, a fixed point, and the directrix, a fixed line. As the topic of conic sections depends heavily on the parabola, all of the parabola-related concepts are covered here.

The x-intercepts of a parabola are where the parabola intersects the x-axis on its graph. There are a number of ways to find the x-intercepts of a parabola, and each one is usually specific to each situation.

In the case, when you are given the graph, the easiest way to find x-intercepts is to identify points at which parabola intersects the x-axis.

From your graph, parabola intersects x-axis at two points: (-5,0) and (-4,0)

The value of x in the rectangle is 36.

A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.

All angles measure 90∘ in a rectangle. The sum of angles in a rectangle is 360 degrees.

Therefore, let's find the value of x in the angles.

Hence,

∠2 = x + 30

∠5 = 2x - 48

Therefore,

∠2 + ∠5 = 90°

x + 30 + 2x - 48 = 90

3x - 18 = 90

3x = 90 + 18

3x = 108

divide both sides by 3

x = 108 / 3

If Yellow Sticker Business meets its operating income goal, the quarterly safety margin in dollars will be $4,583.33.

Budgeting, debt reduction, and setting up an emergency fund are important short-term objectives. Key insurance policies should be included in medium-term goals, whilst retirement should be the primary emphasis of long-term objectives.

Next, we deduct our break-even sales from actual sales at the goal operating income level to determine the margin of safety:

Real sales are determined by dividing target operating income by total fixed costs and contribution margin ratio.

Real sales equal $8,250 plus $15,000 / 0.60.

Real sales were $29,583.33

Safety margin = Real sales Breakeven sales

Margin of safety is calculated as $29,583.33 - ($0.50 x 50,000 units).

$25,000 - 29,583.33 is the margin of safety.

$4,583.33 is the safety margin.

Hence, 160 mL of oxygen is contained inside a 200 mL air tank using the same ratio as a 500 mL air tank.

Ratios contrast two figures by ordinarily dividing them. A/B would be your formula if you were trying to compare one piece of data (A) to some other data point (B). We are multiplying information A by data B, as this suggests. In the event that A and B are both 5, for example, your ratio would've been 5/10.

80% of 500 mL of oxygen if indeed the air tank contains 80% oxygen & 20% nitrogen, which is:

0.80 x 500 mL = 400 mL

This means that the air tank contains 400 mL of oxygen and 100 mL of nitrogen.

To find the amount of oxygen in a 200 mL air tank that contains the same ratio, we need to use proportions:

If 500 mL contains 400 mL of oxygen, then 1 mL contains 400/500 = 0.8 mL of oxygen.

Therefore, if 200 mL contains the same ratio of oxygen, it will contain:

0.8 mL x 200 mL = 160 mL

So, the amount of oxygen in a 200 mL air tank with the same ratio as the 500 mL air tank is 160 mL.

An equation to represent relationship of the weights shown on the scale include the following: 22 + x = 34.

Based on the information provided about the weights on this balanced scale, we can logically deduce the following parameters;

Each small square = 1 unit.

Each larger square = 10 units.

The variable x represent the weight of the triangle.

Since there are four small squares and three large squares each labeled ten on one side of this balanced scale, we have:

Total weight = 4(1) + 3(10)

Total weight = 34 units.

Similarly, there are two small squares, two large squares, and a triangle labeled x on the other side of this balanced scale, we have:

Total weight = 2(1) + 2(10) + x

Total weight = 22 + x

By equating the two equations, we have:

The radius r for the circle C is equal to 39 using the Pythagoras rule for the right triangle ABC

Since the line AB is tangent to the circle at point B, then the triangle ABC is a right triangle and the Pythagoras rule can be applied as follows:

(50 + r)² = r² + 80²

r² = (50 + r)² - 80²

r² = (50 + r - 80)(50 + r + 80) {difference of two square}

r² = (r - 30)(r + 130)

r² = r² + 130r - 30r - 3900 {expansion of brackets}

r² - r² + 130r - 30r = 3900 {collect like terms}

100r = 3900

Answer:

To solve for x, we can start by cross-multiplying the equation to eliminate the denominators:

(a+bx)(c+d) = (c+dx)(a+b)

Expanding the terms on both sides:

ac + adx + bc + bdx^2 = ac + abx + cdx + bd

Simplifying and rearranging the terms:

adx + bdx^2 - abx - cdx = bd - ac

dx(ad - ab - c) = bd - ac

Now, since we know that cb=ad, we can substitute ad=cb into the equation:

dx(cb - ab - c) = bd - ac

dx(cb - ab - c) = b(cd - ac)

x = b(cd - ac)/(d(cb - ab - c))

Therefore, the solution for x is:

x = b(cd - ac)/(d(cb - ab - c))

The volume of the solid is (64/3)√3 cubic units, which is answer choice B.

A circle is a geometric shape in a two-dimensional plane, consisting of all the points that are at a fixed distance, called the radius, from a given point, called the center. The distance around the circle is called the circumference. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159. The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Circles have many real-world applications, such as in the design of wheels, gears, and other rotating objects. They are also important in mathematics and science, as they provide a simple and elegant way to study and understand the properties of curves and curved surfaces.

We can approach this problem by considering a vertical slice of the solid taken perpendicular to the y-axis. This slice will be an equilateral triangle with a side length that depends on the y-coordinate.

At y = 0, the circle x² + y² = 16 intersects the x-axis at x = ±4. This means that the equilateral triangle at y = 0 has side length 2√3 times the distance from the origin to the x-axis, which is 4√3. Therefore, the area of this triangle is:

A(0) = (√3/4) (4√3)² = 12√3

At a general y-coordinate y > 0, the equilateral triangle will have side length equal to the distance between the points where the circle intersects the line y = k, where k is the y-coordinate. This distance can be found using the Pythagorean theorem:

d = √(16 - k²) - √k² = √(16 - 2k²)

The area of the equilateral triangle at y is then:

A(y) = (√3/4) d² = (√3/4) (16 - 2k²)

To find the volume of the solid, we can integrate the cross-sectional areas with respect to y from 0 to 4, using the formula for the area of an equilateral triangle:

V = ∫(0 to 4) A(y) dy = ∫(0 to 4) (√3/4) (16 - 2k²) dy

= (√3/4) (16y - (2/3) y³)|0 to 4

= (√3/4) [(64 - (2/3)(64)) - (0 - 0)]

= (64/3)√3

To add mixed numbers, we need to add the whole numbers separately and fractions separately.

Starting with the whole numbers, we have:

9 1/2 − 3 7/8 + 4 4/5 − 1 1/2

= (9 + 4) − (3 + 1) + (4/5 − 1/2) + (1/8 − 7/8) (grouping the terms)

= 10 − 4 + (8/10 − 5/10) + (−6/8) (converting fractions to have a common denominator)

= 6 + 3/10 − 3/4 (simplifying fractions and adding whole numbers)

Weight is the force of gravity that pulls objects toward the core of the Earth. The resulting force that pulls a substance toward Earth is known as gravity. In contrast to gravity force, which occurs among any two masses, this only occurs between Earth as well as a mass.

First, we need to convert all the weights to grams, since the weight limit is given in kilograms and the weights of clothes, electrical accessories, and toiletries are given in grams.

Maximum weight limit = 2020 kg = 2020000 g

Weight of empty suitcase = 33 kg = 33000 g

Weight of clothes = 55 kg = 55000 g

Weight of electrical accessories = 44 kg = 44000 g

Weight of 55 hardback books = 55 x 720720 g = 39639600 g

Weight of toiletries = 46004600 g

Total weight of suitcase and contents = 33000 + 55000 + 44000 + 39639600 + 46004600 = 125642200 g

Amount over maximum weight limit = total weight - maximum weight limit = 125642200 - 2020000 = 123622200 g

We may be confident that this is the correct scale factor because both equation equations yield the same value of k. As a result, the dilatation has a scale factor of 5/8 and is centered at the origin.

An equation is a statement in mathematics that states the equality of two expressions. An equation has two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the value "9". The purpose of equation solving is to determine which variable(s) must be changed in order for the equation to be true. Simple or complex equations, regular or nonlinear equations, and equations with one or more elements are all possible. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are employed in a variety of mathematical disciplines, including algebra, calculus, and geometry.

Let (x,y) be a point on the plane and k be the dilation scale factor centred at the origin. The image of (x,y) under dilation is thus given by (kx, ky).

The dilation is given as (4,6) to (5/2,15/4). That is to say:

3x² -2xy + 4y² at x = -1, y = -2  = 15

Step-by-step explanation:

Given function is

f(x, y) = 3x² -2xy + 4y²

To find At x = - 1 and y - 2 just plug these values for x and y into f(x, y)

f(-1, -2) = 3(-1)² - 2(-1)(-2) + 4(-2)²

(-1)² = 1 ==>   3x²  = 3(-1)² = 3 x 1 = 3

(-1) (-2) = 2   ==>   2xy = 2(-1)(-2) = 2 x 2 = 4

(-2)² = 4  ==> 4y² = 4 (-2)² = 4 x 4 = 16

f(-1 1, - 2) = 3x² -2xy + 4y²

Okay, just think of dilations as scaling the object bigger or smaller. You are just multiplying all points on the shape by a common scalar.

The only other thing is a negative dilation reflects the shape over the origin (which is quite intuitive cause you negate all the coordinates).

Now for question 1 your just trying to find the scale factor given an original point and a dilated point. Since all points are multiplied by the same factor,

(-3,6)x = (-4,8)

x=4/3

For the second question, just check points to see if all follow the same dilation scale factor. For our purposes it suffices to just check the each vertex.

(1,1) -> (2,2) so the scale factor must be 2

(1,4) -> (2,8) good

(5,1) -> (10,2) good

(5,4) -> (10,8) good

So, this transformation describes a dilation. The scale factor is 2.

Therefore, the difference between the most common and least common amounts on the line plot is 8.

"Least common" refers to the item or value that appears the fewest number of times in a given set or group. For example, if you have a set of numbers {2, 4, 2, 5, 3, 4, 1}, the least common number in the set is 1 because it appears only once, while the most common number is 2 and 4 because they both appear twice. In a line plot, the least common amount is the one that appears the fewest number of times on the p.

Given by the question.

To find the difference between the most common and least common amounts on a line plot, follow these steps:

Look at the line plot and identify the most common amount. This is the amount that appears the most frequently on the plot.

Look at the line plot and identify the least common amount. This is the amount that appears the least frequently on the plot.

Subtract the least common amount from the most common amount. The result will be the difference between the most common and least common amounts on the line plot.

Step-by-step explanation:

All sides of a rhombus are the same length. Therefore, for rhombus MAZE:

[tex]\sf \overline{AZ} = \overline{AM} = \overline{ZE} = \overline{EM}[/tex]

Given:

As the sides of a rhombus are the same length, we can equate the expressions for sides AZ and AM, and solve for b:

[tex]\begin{aligned}\overline{\sf AZ}&=\overline{\sf AM}\\8b-4&=5b+8\\8b-4-5b&=5b+8-5b\\3b-4&=8\\3b-4+4&=8+4\\3b&=12\\3b \div 3&=12 \div 3\\b&=4\end{aligned}[/tex]

Therefore, the value of b is 4.

To find the length of AZ and AM, substitute the found value of b into one of the expressions:

[tex]\begin{aligned}\overline{\sf AZ}&=8b-4\\&=8(4)-4\\&=32-4\\&=28\end{aligned}[/tex]

Therefore, as AZ = AM, then AZ = 28 and AM = 28.

[tex]\hrulefill[/tex]

As the sides of a rhombus are equal in length, each side length is 28 meters (as found previously).

The perimeter of rhombus MAZE is the sum of its side lengths. Therefore:

[tex]\begin{aligned}\sf Perimeter\;MAZE&=\sf \overline{AZ} +\overline{AM} +\overline{ZE}+ \overline{EM}\\&=28+28+28+28\\&=112\; \sf meters\end{aligned}[/tex]

Therefore, the perimeter of rhombus MAZE is 112 meters.

[tex]\hrulefill[/tex]

The point of intersection of the diagonals of rhombus MAZE is point X.

As the diagonals of a rhombus are perpendicular bisectors of each other, then:

[tex]\sf \overline{AX}=\overline{EX}\quad and \quad \overline{AX}+\overline{EX}=\overline{AE}[/tex]

[tex]\sf\overline{MX}=\overline{ZX}\quad and \quad\overline{MX}+\overline{ZX}=\overline{MZ}[/tex]

Given MZ = 44 meters, and MX is half of MZ, then:

[tex]\sf \overline{MX}=\overline{ZX}=22\;meters[/tex]

As the diagonals bisect each other at 90°, m∠MXA= 90°. Therefore, ΔMXA is a right triangle with hypotenuse AM = 28 and leg MX = 22.

As we know the lengths hypotenuse AM and leg MX, we can use Pythagoras Theorem to calculate the length of the other leg, AX:

[tex]\begin{aligned}\sf \overline{AX}^2+\overline{MX}^2&=\sf \overline{AM}^2\\\sf \overline{AX}^2+22^2&=\sf 28^2\\\sf \overline{AX}^2&=\sf 28^2-22^2\\\sf \overline{AX}&=\sqrt{\sf 28^2-22^2}\\\sf \overline{AX}&=\sf 10\sqrt{3}\; meters\end{aligned}[/tex]

As the diagonals bisect each other, AX = EX. Therefore:

[tex]\sf \overline{EX}=\sf 10\sqrt{3}\; meters[/tex]

The length of diagonal AE is the sum of segments AX and EX. Therefore:

[tex]\begin{aligned}\sf \overline{AE}&=\sf \overline{AX}+\overline{EX}\\&=\sf 10\sqrt{3}+10\sqrt{3}\\&=\sf 20\sqrt{3}\; meters\end{aligned}[/tex]
