Determine the distance between the Woozy Wheel and the Roller Rail.

119 units
11 units
169 units
13 units

Answers

Answer 1
To find the distance between two points on a coordinate plane, use the distance formula: d = √((x2 - x1)^2 + (y2 - y1)^2).

The coordinates for Woozy Wheel are (-14, 1) and for Roller Rail are (-2, -4).

d = √((-2 - (-14))^2 + (-4 - 1)^2)
d = √((12)^2 + (-5)^2)
d = √(144 + 25)
d = √169

The distance between Woozy Wheel and Roller Rail is 13 units (since √169 = 13). So, the correct answer is 13 units.

Which digit in the following number is the one that determines its precision?
34.81

Answers

Answer: The digit in the following number is the one that determines its precision is 1.

Step-by-step explanation:

Precision is the ability to consistently produce outcomes with a high degree of accuracy. In general, precision can be thought of as the opposite of randomness or imprecision. It is also important for creating and maintaining machines, such as those in manufacturing, and for ensuring that the parts involved in a process fit together exactly as they should.

34.81 is a number with decimal digits up two places behind the decimal.

Since this number is 34.81, the precision is determined by the value at the 2nd decimal place which is 1 since it determines the how the value is performing at the second decimal place after the first decimal place. Hope this helps!

In the given diagram, given that the shapes have the same area, the value of y is 3.

Calculating Area: Determining the value of y

From the question, we are to determine the value of y in the given diagram.

From the given information,

The yellow shapes have the same area.

The area of the shape is

Area = 8 × (3y + 1)

Area = 24y + 8

For the second shape,

Area = (15 × (y + 5)) - (4 × (7y - 11))

Area = (15y + 75) - (28y - 44)

Area = 15y + 75 - 28y + 44

Area = 119 - 13y

Since the shapes have the same area, we can write that

24y + 8 = 119 - 13y

24y + 13y = 119 - 8

37y = 111

y = 111/37

y = 3

Lilly describes a shape.
Lilly says, "The shape has four sides. It has two pairs of equal opposite sides. The opposite sides are parallel."

Robin says there are two possible shapes. Is she correct? Explain your answer.​

Answers

Yes, there are two possible shapes that fit this description.

Lilly is describing a parallelogram, which is a quadrilateral with two pairs of parallel opposite sides.

A parallelogram has opposite sides that are congruent and parallel, and opposite angles that are congruent. Therefore, it has two pairs of equal opposite sides.

There are two types of parallelograms: a rectangle and a rhombus. A rectangle is a parallelogram with four right angles, while a rhombus is a parallelogram with four congruent sides.

Both shapes have two pairs of equal opposite sides and opposite sides that are parallel.

Therefore, Robin is correct that there are two possible shapes. Depending on whether all four angles are right angles or all four sides are congruent, the shape could be a rectangle or a rhombus. It is also possible for a shape to be both a rectangle and a rhombus, in which case it would be called a square.

What is a Cyclic Quadrilatera l?

A cyclic quadrilateral, also known as an inscribed quadrilateral in Euclidean  geometry, is a quadrilateral with all   of its vertices on a single circle.

To determine the size of angle C in terms of x and y, we can use the fact that tangent BC touches the circle ABDE at B.

This means that angle C is equal to the angle formed between the chord AD and the tangent BC at point B.

4.1.1

Since AB || EC, we can use the alternate interior angles theorem to determine the relationship between angles C and A₁.

Angle C is equal to angle A₁ because they are corresponding angles.

Therefore, the size of angle C is y.

4.1.2   - To determine if BCDF is a cyclic quadrilateral

 In order to check if BCDF is cyclic, we need to determine if the opposite angles in the quadrilateral add up to 180° .

Let's consider angle BCD and angle BFD:

Angle BCD is equal to angle B₁ (given) and is represented by x.

Angle BFD is equal to angle A₁ (since BCDF is a cyclic quadrilateral) and is represented by y.

If x + y = 180 degrees, then BCDF is a cyclic quadrilateral.

minimum possible integral value of k such that the equation 2^2x - 2(k-1)2x+k=0 has one root less than 1 and other root greater than 1

Answers

ANSWER:

Finding the smallest possible integer value of k requires analyzing the given equation and determining the conditions under which one root is less than 1 and the other is greater than 1.

The equation is:

2^(2x) - 2(k-1)^(2x) + k = 0

Let's break down the conditions step by step.

1. Square root less than 1:

To make the square root less than 1, we need to substitute x = 1 into the equation and get a positive value. So if x = 1, then

2^(2*1) - 2(k-1)^(2*1) + k > 0

4 - 2(k-1)^2 + k > 0

Extensions and simplifications:

4 - 2(k^2 - 2k + 1) + k > 0

4 - 2k^2 + 4k - 2 + k > 0

-2k^2 + 5k + 2 > 0

2k^2 - 5k - 2 < 0 xss=removed xss=removed xss=removed xss=removed > 0.

Now we can combine both conditions to find the smallest integer value of k.

2k^2 - 5k - 2 < 0 > 0 (Condition 2)

By solving these conditions simultaneously, we can find the range of values of k that satisfy both conditions and determine the smallest integer value of k. However, this process requires calculations and algebraic manipulations beyond the scope of simple text-based answers.

It is recommended to use an algebraic calculator or software to solve the equation and find the smallest integer value of k that satisfies the given conditions.

suppose set a contains 39 elements and the total number elements in either set a or set b is 80. if the sets a and b have 1 elements in common, how many elements are contained in set b?

Answers

Answer:

42 elements

-----------------------

Using the formula for the union of two sets:

|A ∪ B| = |A| + |B| - |A ∩ B|

where

|A| represents the number of elements in set A, |B| represents the number of elements in set B, and |A ∩ B| represents the number of elements in both sets A and B.

We are given that:

|A| = 39|A ∩ B| = 1|A ∪ B| = 80

Plugging in the values, we get:

80 = 39 + |B| - 1 |B| = 80 - 38|B| = 42

Therefore, set B contains 42 elements.

An equation, in slope-intercept form, for the line of best fit for the table  above is y = 0.05x + 0.7.

How to determine an equation of this line?

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

x and y represent the data points.m represent the slope.

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (1.3 - 1.1)/(4 - 8)

Slope (m) = -0.2/4

Slope (m) = 0.05

At data point (8, 1.1) and a slope of 0.05, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1.1 = 0.05(x - 8)  

y = 0.05x - 0.4 + 1.1

Matching the outcomes to each event:

P(4): Equally likely. Each face of the cube has an equal chance of landing face up, so the probability of rolling a 4 is the same as the probability of rolling any other single number.

Therefore, P(4) is equally likely.

P(greater than 1): Likely. There are five faces that have a number greater than 1 (2, 3, 4, 5, and 6) and only one face that has a 1.

Therefore, the probability of rolling a number greater than 1 is much higher than the probability of rolling a 1, making it a likely outcome.

P(even): Equally likely. There are three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5) on the cube, so the probability of rolling an even number is the same as the probability of rolling an odd number. Therefore, P(even) is equally likely.

The height of a stack of cups is a function of the number of cups in the stack. If a 7.5" cup with a 1.5" lip is stacked vertically, determine a function that would provide you with the height based on any number of cups. Hint Start with the height of one cup and create a table, list, graph or description that describes the pattern of the stack as an additional cup is added.​

Answers

The function that provides the height of the stack of cups based on any number of cups is height(n) = 7.5 + 1.5(n-1)

Let's assume that the height of one cup is 7.5 inches.

When we add the second cup, the bottom of the second cup rests on the top of the first cup, including the 1.5" lip.

Therefore, the height of the second cup is 7.5 inches plus 1.5 inches, or 9 inches.

When we add the third cup, the bottom of the third cup rests on the top of the second cup, including the 1.5" lip.

Therefore, the height of the third cup is the height of the first two cups plus 1.5 inches, or 16.5 inches.

The function we get by continuing this pattern for any number of cups n by using the formula:

height(n) = 7.5 + 1.5(n-1)

Therefore, the function that provides the height of the stack of cups based on any number of cups is height(n) = 7.5 + 1.5(n-1)

Jim told Joyce, "I am twice as old now as I was when I was as old as you are now. When you are as old as I am now, the sum of our ages will be 63." How old is Joyce now?

Answers

According to the information we can infer that Jim is currently 42 years old.

How to calculate how old is Joyce now?

To calculate how old is Joyce now let's start by assigning variables to the unknown ages:

Let's say Jim's current age is J.Let's say Joyce's current age is K.

Using the information given in the problem, we can create two equations:

"I am twice as old now as I was when I was as old as you are now."

This means that Jim's age when Joyce was K years old is equal to J - K. According to the statement, J is now twice this age. So we can write:

J = 2(J - K)

"When you are as old as I am now, the sum of our ages will be 63."

This means that when Joyce is J years old, their ages will add up to 63. So we can write:

J + K = 63

Now we have two equations with two variables. We can use substitution to solve for one of the variables:

From equation 1, we know that J = 2(J - K), so J = 2J - 2K, which simplifies to J = 2K.

We can substitute this expression for J in equation 2: 2K + K = 63, which simplifies to 3K = 63. Therefore, K = 21.

So Joyce is currently 21 years old. To find Jim's age, we can use equation 1 and substitute K = 21:

J = 2(J - 21)J = 42

After following the steps of quadratic equation described below,

We can prove,

⇒ x =  -b±√(-4ac+  b²)/2a

Given that;

The quadratic equation is,

ax²+bx+c = 0,

As a result, the following steps must be taken to obtain the quadratic formula from the equation:

ax²+bx+c = 0

Take subtraction of c both sides.

ax²+bx+c-c = 0-c

ax²+bx = -c

Substitute a for both sides of the equation.

ax²/a + bx/a = -c/a

x² + bx/a = -c/a

Complete the square by adding  (b/2a)² times a squared to each sides.

x² + bx/a +  (b/2a)² = -c/a +  (b/2a)²

Square the quantity  b/2a on the right side of the equation

x² + bx/a +  (b/2a)² =  -c/a +  b²/4a²

Find the lowest common denominator on the right side of the equation. 4a²

x² + bx/a +  (b/2a)² =  -4ac/4a² +  b²/4a²

Add the fractions on the right side of the equation together.

x² + bx/a +  (b/2a)² =  (-4ac+  b²)/4a²

Because, as shown in the question, the fraction on the right-hand side of the equation is to be added together rather than multiplied.

As demonstrated, the equation on the left should be expressed as a perfect square.

(x+b/2a)² =  (-4ac+  b²)/4a²

Add the square roots of both sides together.

√(x+b/2a)² = √ (-4ac+  b²)/4a²

(x+b/2a) =  √(-4ac+  b²)/2a

Take b/2a off both sides.

x+b/2a - b/2a =  -b/2a + √(-4ac+  b²)/2a

x =  -b/2a + √(-4ac+  b²)/2a

Add the fractions on the right side together.

Start with the expression: 3/5 × (-6 + 2 2/3) ÷ 1 1/2 - 1 1/8 - 5/2 + (1 4/5 ÷ 9/10).

Simplify the addition and subtraction within parentheses first:

-6 + 2 2/3 = -6 + 8/3 = -18/3 + 8/3 = -10/3

1 4/5 ÷ 9/10 = 9/5 ÷ 9/10 = 9/5 × 10/9 = 90/45 = 2

Now the expression becomes: 3/5 × (-10/3) ÷ 1 1/2 - 1 1/8 - 5/2 + 2.

Next, let's simplify the division:

-10/3 ÷ 1 1/2 = -10/3 ÷ 3/2 = -10/3 × 2/3 = -20/9

The expression now becomes: 3/5 × (-20/9) - 1 1/8 - 5/2 + 2.

Now let's simplify the subtraction:

1 1/8 = 8/8 + 1/8 = 9/8

The expression becomes: 3/5 × (-20/9) - 9/8 - 5/2 + 2.

Convert all fractions to a common denominator:

The common denominator for 5, 9, 8, and 2 is 360.

The expression becomes: (3/5) × (-160/72) - (9/8) × (45/45) - (5/2) × (180/180) + (2/1) × (180/180).

Perform the multiplications:

(3/5) × (-160/72) = -480/360 = -4/3

(9/8) × (45/45) = 405/360 = 9/8

(5/2) × (180/180) = 900/360 = 5/2

(2/1) × (180/180) = 360/360 = 1

The expression becomes: (-4/3) - (9/8) - (5/2) + 1.

Simplify the expression:

-4/3 - 9/8 - 5/2 + 1 = (-128/96) - (27/24) - (60/48) + (48/48) = -128/96 - 108/96 - 120/96 + 48/48

= (-128 - 108 - 120 + 48)/96 = -308/96 = -77/24.

Therefore, the value of n is -77/24.

Jahlil is 6 inches shorter than 4 times his sister’s height. Jahlil’s height is 70 inches.

Which equation represents h, his sister’s height in inches?
1.4 h + 6 = 70
2.4 h minus 6 = 70
3.6 h + 4 = 70
4.6 h minus 4 = 70

Answers

Let's first write down the given information in the form of an equation:

Jahlil's height = 70 inches
Jahlil's height = 4 times his sister's height - 6 inches

So, we can write the equation as:

70 = 4h - 6

where h represents his sister's height in inches.

Now, let's solve for h:

70 + 6 = 4h

76 = 4h

h = 76/4

h = 19

Therefore, Jahlil's sister's height is 19 inches.

The correct equation that represents h, his sister's height in inches is 1. 4h + 6 = 70.

If there are 2 red balls, 2 blue balls and 4 green balls in a pail, what is the probability of pulling out a red ball?

Answers

The chance of drawing a red ball has the value P (red ball) = 1/4.

We have to given that;

There are 2 red balls,

And,  2 blue balls

And, 4 green balls in a pail.

Since, We know that;

The possibility of an event happening is referred to as probability. Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value

Hence, Total number of balls is,

= 2 + 2 + 4

= 8

So, the probability of pulling out a red ball is,

⇒ P = 2 / 8

⇒ P = 1/4

Explain how to prove that (secx÷cosx)-(tanx÷cotx)=1

Answers

The trigonometric identity, (sec(x) ÷ cos(x)) - (tan(x) ÷ cot(x)) is equivalent to the Pythagorean identity sec²(x) - tan²(x) = 1, therefore;

(sec(x) ÷ cos(x)) - (tan(x) ÷ cot(x)) = sec²(x) - tan²(x) = 1

What is a trigonometric identity?

A trigonometric identity is an equation involving trigonometric ratio which is correct for possible values of the input variables.

The specified trigonometric identities can be presented as follows;

sec(x) ÷ cos(x) - tan(x) ÷ cot(x) = 1

cos(x) = 1/sec(x)

tan(x) = 1/cot(x)

cot(x) = 1/tan(x)

Therefore; sec(x) ÷ cos(x) - tan(x) ÷ cot(x) = sec(x) ÷ (1/sec(x)) - tan(x) ÷ (1/tan(x)) = 1

Therefore;

sec(x) ÷ cos(x) - tan(x) ÷ cot(x) = sec²(x) - tan²(x)

The Pythagorean identities, indicates that we get;

sec²(x) - tan²(x) = 1

Answer:

[tex]x^2+\left(b^3-3bc\right)x+c^3=0[/tex]

[tex]\alpha = 1 \quad \textsf{and} \quad \beta=2[/tex]

[tex]b=-3[/tex]

Step-by-step explanation:

If α and β are roots of x² + bx + c = 0 then the equation must be:

[tex](x -\alpha)(x - \beta) = 0[/tex]

Expanding we get:

[tex]x^2-\beta x - \alpha x + \alpha \beta = 0[/tex]

[tex]x^2-(\alpha +\beta ) x + \alpha \beta = 0[/tex]

Equating the coefficients we get:

[tex]\alpha + \beta=-b[/tex]

[tex]\alpha \cdot \beta=c[/tex]

For an equation with the roots α³ and β³, the sum of the roots can be rewritten in terms of (α + β) and (α·β) using the Sum of Cubes formula, and the Square of Binomials formula:

[tex]\begin{aligned}\alpha^3+\beta^3&=(\alpha + \beta)(\alpha^2-\alpha\beta+\beta^2)\\&=(\alpha + \beta)(\alpha^2+2\alpha\beta+\beta^2-3\alpha\beta)\\&=(\alpha + \beta)((\alpha+\beta)^2-3\alpha\beta))\end{aligned}[/tex]

Substitute in the expressions for (α + β) and αβ to find the sum of the roots α³ and β³ in terms of b and c:

[tex]\begin{aligned}\alpha^3+\beta^3&=(\alpha + \beta)((\alpha+\beta)^2-3\alpha\beta))\\&=(-b)((-b)^2-3c))\\&=-b(b^2-3c)\\&=-b^3+3bc\end{aligned}[/tex]

The product of the roots α³ and β³ in terms of c is:

[tex]\alpha \cdot \beta = c[/tex]

[tex](\alpha \cdot \beta)^3 = c^3[/tex]

[tex]\alpha^3 \cdot \beta^3=c^3[/tex]

For a quadratic equation in the form x² + bx + c = 0:

The sum of the roots is equal to -b.The product of the roots is equal to c.

So for x² + bx + c = 0 with roots α³ and β³:

[tex]x^2-(\alpha^3 + \beta^3)x+(\alpha^3 \cdot \beta^3)=0[/tex]

[tex]x^2-\left(-b^3-3bc\right)x+c^3=0[/tex]

[tex]x^2+\left(b^3-3bc\right)x+c^3=0[/tex]

Therefore, the equation with the roots α³ and β³ is:

[tex]\boxed{x^2+\left(b^3-3bc\right)x+c^3=0}[/tex]

Substitute the given value of c = 2:

[tex]x^2+\left(b^3-3b(2)\right)x+2^3=0[/tex]

[tex]x^2+\left(b^3-6b\right)x+8=0[/tex]

If b³ - 6b + 9 = 0, then (b³ - 6b) = -9.

Substitute this into the equation:

[tex]x^2-9x+8=0[/tex]

Factor:

[tex](x-1)(x-8)=0[/tex]

Therefore, the roots of the equation with the roots α³ and β³ are 1 and 8, so the values of α and β are:

[tex]\alpha^3 =1 \implies \alpha = 1[/tex]

[tex]\beta^3=8 \implies \beta=2[/tex]

To find the real roots of b³ - 6b + 9 = 0, substitute the found values of α and β into the expression for b:

[tex]b=-(\alpha + \beta)[/tex]

[tex]b=-(1+2)[/tex]

[tex]b=-3[/tex]

Therefore, the real root of b³ - 6b + 9 = 0 is b = -3.

We can confirm this by substituting b = -3 into the equation:

[tex]\begin{aligned}(-3)^3-6(-3)+9&=-27+18+9\\&=-9+9\\&=0\end{aligned}[/tex]
