Answer 1

Answer:

A) <5 and <6 are commentary

B) 72

C < 4 = 22

<3 = 68

Step-by-step explanation:

A) The square drawn over the 2 angles shows that the angles together measure 90 degrees

B) 90 - 18 = 72

C) 4x -10 + 5x + 28 = 90  Combine like terms

9x + 18 = 90  Subtract 18 from both sides

9x = 72   Divide both sides by 9

x = 8

<4

4x - 10

4(8) - 10

32 - 10

<4 = 22

<3

5x + 28

5(8) + 28

40 + 28

68

<3 = 68

Answer 2

Answer:

Part A: Yes, ∠5 and ∠6 are complementary angles because they add up to 90°.

Part B: If the measure of ∠6 is 18°, then the measure of ∠5 is 72° because ∠6+∠5=90° so 90°-18°=72°.

Part C: ∠4+∠3=90°

(4x-10)°+(5x+28)°=90°

add 10 to both sides

4x+5x+28=100

subtract 28 from both sides

4x+5x=72

combine like terms

9x=72

divide both sides by 9

x=8

now plug 8 in for x

∠4=(4(8)-10)°

∠4=22°

∠3=(5(8)+28)

∠3=68°

22°+68°=90°

two airplanes take off from the airport at the same times heading in opposite directions. after 2 hours the planes are 1500 miles apart. if the speeds of the planes differ by 50 mph, find the speed of the slower plane

Answers

Speed of the slower plane = 350 miles/hour

What is relative speed?

Relative speed is the speed of a moving body in relation to another. When two bodies are moving in the same direction, their difference is used to calculate their relative speed. When two bodies are moving in opposite directions, however, the relative speed is derived by summing their speeds.

Given,

Two planes heading opposite directions

After 2 hours the planes are 1500 miles apart.

Speeds of the planes differ by 50 mph

Let the speed of slower plane be x

then speed of faster plane = x + 50

Since, plane are moving in opposite directions

Relative speed = x + x + 50

Speed = distance /time

x + x + 50 = 1500/2

2x + 50 = 750

2x = 750 - 50

x = 700/2

x = 350 miles/hour

Hence, 350 miles/hour is the speed of slower plane.

Curved urface area of a cone i 308 cm2 and it lant height i 14 cm. Find the volume

Answers

Curved surface area of a cone is 308 cm² and it slant height is 14 cm. So the cone volume is 343√3/3 π cm³.

Determine the cone volume

These are the specified parameters:

Curved surface area of a cone (A) = 308 cm²

Slant height (s) = 14 cm

The length of the radius of the base of the cone

A = π r s

308 = 22/7 × r × 14

308 = 44 r

  r = 308/44

  r = 7 cm

The cone height

h² = s² - r²

    = 14² - 7²

    = 196 - 49

    = 147

h = √147

h = 7√3 cm

Cone volume

In the equation value of A=[tex]\frac{-32}{5} , B= \frac{36}{5} , C= \frac{1}{10} , D= \frac{-7}{2}[/tex].

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here the given equation is [tex]\frac{3x^3+4x^2-6x}{x^2+2x+2}= \frac{(Ax+B)}{x^2+2x+2}+\frac {C}{(x-1)}+\frac{D}{x+1}[/tex]

In RHS we multiply to get common denominator. Hence

=> [tex]\frac{3x^3+4x^2-6x}{(x^2+2x+2)(x^2-1)}= \frac{(Ax+B)(x^2-1)+C(x^2+2x+1)(x+1)+D(x-1)(x^2+2x+2)}{(x^2+2x+2)(x^2-1)}[/tex]

Removing the common denominator we get

=> [tex]{3x^3+4x^2-6x}= (Ax+B)(x^2-1)+C(x^2+2x+1)(x+1)+D(x-1)(x^2+2x+2)[/tex]

=> [tex]3x^3+4x^2-6x=Ax^3-Ax+Bx^2-B+Cx^3+Cx^2 +2Cx^2 +2Cx+2Cx+2C+D(x^3 +2x^2 +2x-x ^2 -2x-2)[/tex]

=> [tex]$ 3x^3+4x^2-6x =(A+C+D)x^3+ (B+3C+D)x^2+(-A+2C+2C)x + (-B+2C-2D)[/tex]

We can compare the coefficients to get

3=A+C+D−−−−−−−−1

4=B+3C+D−−−−−−2

−6=−A+4C−−−−−3

0=−B+2C−2D−−−−−−4

Add 2 and 4  then

=> 4 = 5C-D -----------5

Add 1 and 3 then

=> -3 =5C+D--------6

Now subtract 5 from 6 then

=> -7=2D

=> D = -7/2

Now put D=-7/2 into 5 then

=> 4=5c+7/2

=> 1/2=5C

=> C= 1/10

Now put value of C into 3 then

=> -6=-A+ 4×1/10

=> -6-2/5 = -A

=> A = -32/5

Now put C and D into 2 then

=> 4=B+3C+D

=> 4 = B+3/10-7/2

=> 4 = B-32/10

=>4+32/10 = B

=> B= 36/5

Hence in the equation value of A=[tex]\frac{-32}{5} , B= \frac{36}{5} , C= \frac{1}{10} , D= \frac{-7}{2}[/tex].

The Domain of a function is the set of all possible input values (values of x) for which the function is defined and produces a valid output (value of y).

For the function g(x) = (x² - 3x - 18)/(x² − 4), the only restriction on the domain is the denominator (x² − 4) cannot be equal to 0. This is because division by zero is undefined.

Answers

Scatterplots are best for showing the relationship between two interval/ratio variables and indirect or negative relationship between two ratio variables.

Scatterplots are best for showing:

⇒the relationship between two interval/ratio variables

⇒indirect or negative relationship between two ratio variables

Scatterplots display points on a coordinate plane, with one variable plotted on the x-axis and the other variable plotted on the y-axis. This allows us to see the pattern of relationship between the two variables. If there is a positive or negative relationship, we can see if the points tend to increase or decrease as we move from left to right or from bottom to top. If the relationship is indirect, we can see if the points tend to curve in one direction or another.

Scatterplots are not the best visualisation for showing: correlation

frequency of two nominal variables

For showing correlation, a line of best fit (regression line) can be added to a scatterplot, but other visualizations such as a correlation matrix or a heat map are more commonly used.

For showing frequency of two nominal variables, a two-way table or a mosaic plot are better suited, as they can display the count or proportion of cases for each combination of the two nominal variables.

Therefore, Scatterplots are best for showing the relationship between two interval/ratio variables and indirect or negative relationship between two ratio variables.

trash can            $14.50                    $1.051                 $15.551

What is sales tax?

The mandatory tax imposed on the whole value of the items sold is known as the sales tax. Depending on the type of products sold, different sales tax rates apply.

The final amount of sales tax is added to the sale price of the products in the invoice because it is a charge made to the consumer.

Given the sales tax rate is 7.25%.

sales tax rate = 0.0725

to find sales tax and price including tax,

sales tax = price before tax * sales tax rate

and price including tax = sales tax + price before tax

1:  price before tax = $8.00

sales tax = 8*0.0725

sales tax = $0.58

price including tax = 8.00 + .58 = $8.58

2:  price before tax = $22.00

sales tax = 22*0.0725

sales tax = $1.59

price including tax = 22.00 + 1.595 = $23.595

3:  price before tax = $14.50

sales tax = 14.50*0.0725

sales tax = $1.051

price including tax = 14.50 + 1.051 = $15.551

Hence the table is,

Item            price before tax        sale tax         price including tax

Answers

The slope-intercept equation of the line is y= 9x + 3

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

Slope-intercept form of an equation: y=mx+b, where m is the slope (in this case, 9) and b is the y-intercept (in this case, the 3 from the point 0, 3)

y= 9x + 3 ( Plug in 9 for the m (slope) and 3 for the b (y-intercept))

The perimeter of a rectangle plot of the land whoe length i(2x5)m and width (x-10) m i 80 m. Find the value of x and the area of the plot and the cot of weeding the plot at GHC0. 24 per m2

Answers

Rectangle is the name given to a parallelogram whose neighboring sides are perpendicular to one another. Weeding the rectangle area will cost 0.0042 GHCO.

What is meant by rectangle?Four sides, four corners, and four 90° right angles make up the closed, 2-D shape of a rectangle. A rectangle has parallel, equal sides on either side. Rectangles are two-dimensional shapes, and as such, they have length and breadth as their defining characteristics.The parallel sides of a rectangle are equal to one another, and each of its four vertices is 90 degrees, making it a form of quadrilateral. As a result, it is sometimes referred to as an equiangular quadrilateral. The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.

A. The perimeter of a rectangular plot of land whose length is (2x+5) and width is (x-10) is 80cm. Therefore, we can write,

Perimeter of the rectangle = 2(L+W)

80 = 2[(2x+5)+(x-10)]

80/2 = 2x+5+x-10

40 = 3x -5

40+5 = 3x

x = 15

Hence, the value of x is 15.

B. The rectangle's length is (2x+5) = 2(15)+5 = 35 cm or 0.35 meters.

The rectangle's width is (x-10) = 15-10 = 5 cm = 0.05 m.

The rectangle's area is now LB = 0.35 m 0.05 m = 0.0175 m2.

C. Given that weeding 1 m2 costs 0.24, the price to weed the rectangular area is

Cost is 0.0175 x 0.24 x 0.0042 GHCO.

The price to weed the rectangular plot is therefore 0.0042 GHCO.

A ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. It can be used to express one quantity as a fraction of the other ones.

We shall represent the perimeter of larger figure with the letter x, so that we express their ratios as fractions and solve for x as follows:

4 : 3 = x : 15

4/3 = x/15

x = (4 × 15)/3 {cross multiplication}

x = 4 × 5

x = 20 units

Therefore, the perimeter of the larger figure is equal to 20 units as the two figures have a side ratio of 4:3.

Part A: Create a fifth-degree polynomial in standard form. How do you know it is in standard form? (5 points)

Part B: Explain the closure property as it relates to addition of polynomials. Give an example. (5 points)

(10 points)

Answers

The fifth-degree polynomial in standard form is [tex]2x^5+ 5x^4+ x^3+ 3x^2+ 9x+16[/tex]. The polynomial is in the standard form because the powers of the terms are given in decreasing order.

[tex]2x^5+ 5x^4+16[/tex]  + ([tex]x^5+ 2x^4+11[/tex]) = [tex]3x^5+ 7x^4+17[/tex]

Part A:

The degree of the polynomial is the highest power of the terms of the polynomial.

For example 3x³ + x² + 2x is a polynomial of 3rd degree because the highest power of the terms given is 3.

As we need a polynomial of 5th degree the highest power will be 5.

[tex]2x^5+ 5x^4+ x^3+ 3x^2+ 9x+16[/tex]

The above polynomial is in the standard form because the powers of the terms are given in decreasing order. The first term has the highest power and so on.

Part B:

Suppose we have 2 polynomials

[tex]2x^5+ 5x^4+16[/tex] and [tex]x^5+ 2x^4+11[/tex]

When the closure property of addition is applied

[tex]2x^5+ 5x^4+16[/tex]  + ([tex]x^5+ 2x^4+11[/tex])

= [tex]2x^5+ 5x^4+16[/tex]  + [tex]x^5+ 2x^4+11[/tex]

= [tex]3x^5+ 7x^4+17[/tex]

The coefficients are changed because of addition.

The sign will not be changed due to the addition and like terms are added to get the answer.

10 POINTS!!!!!!!!

Answers

The angle x° =( y+z )° using parallel lines theorem

What are parallel lines?

parallel lines are coplanar infinite straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet.

When a line is used to cross 2 parallel lines, angles are formed and these angles are equal based on some properties.

To prove that x° = (y+z)°

Bisect angle x° into two equal part x1 and x2

y = x1 ( alternate angles are equal)

z = x2 ( corresponding angles are equal)

x1+x2 = x

since x1 = y and x2 = z

we can therefore say x1+x2 = y+z

y+z = x

x° = (y+z)°

the state of Nevada is the shape of a right trapezoid. The bases measure 205 miles and 511 miles, respectively. The distance between the bases is 309 miles. Find the area of the state.

Answers

The area of the trapezoid is A = 1,10,622 miles²

What is a trapezoid?

The Trapezoid is a 4 sided polygon. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.

There are three types of trapezoids , and those are given below:

a) Isosceles Trapezoid

b) Scalene Trapezoid

c) Right Trapezoid

The area of the Trapezoid is given by

Area of Trapezoid = ( ( a + b ) h ) / 2

where , a = shorter base of trapezium

b = longer base of trapezium

h = height of trapezium

Given data ,

Let the area of the trapezoid be represented as A

Now , the shorter base of the trapezoid a = 205 miles

The longer base of the trapezoid b = 511 miles

The height of the trapezoid h = 309 miles

Now , the Area of Trapezoid = ( ( a + b ) h ) / 2

Substituting the values in the equation , we get

Area of Trapezoid A = ( ( 205 + 511 ) x 309 ) / 2

On simplifying the equation , we get

Area of Trapezoid A = 358 x 309

Area of Trapezoid A = 1,10,622 miles²

Hence , the area of the state is 1,10,622 miles²

The total height of the taller tree is 95ft.

Explain the similar triangle?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.Similar triangles are those that feature two triangles that differ in size but have the same angles. The scale factor of similar triangles refers to how they have the same ratio on their corresponding sides.The three triangle similarity theorems, Side-Angle-Side (SAS), Angle-Angle (AA), and Side-Side-Side (SSS), can also be used to compare two triangles.

Given data :

To find the height of the taller tree:

Ratio of base to base = Ratio of height to height

= dws / dws + dwt = hs / ht

= 25 / 25 + 125 = 15 / ht

25 / 150 = 15 / ht

25ht = 15 x 150

25ht = 2250

ht = 2250 / 25

ht = 90

Height of the taller tree above the eye level is 90 ft

To find the total height of the taller tree:

ht + 5 = 90 + 5 = 95

Hence, the total height of the taller tree is 95ft.

What does a probability simple definition entail?

A probability is a number that expresses the possibility or likelihood that a specific event will take place.

                          Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.

Let X shows the random variable corresponding to binomial distribution in the question.

 (a)

      Expected value of the binomial distribution is

       μ = E(X) = ηp =  20 . 040  = 8

and

   σ = √np( 1 - p )  = √20 .04.( 1 - 0.40 )  = √4.8  = 2.19

(b)

For a binomial distribution it is unusal to obtain the sucesses the less than μ - 2.5σ  and greater than μ + 2.5σ

here r = μ - 2.5σ  = 8 - 2.5 . 219 = 2.525

That is for the given binomial distribution it is unusal to obtain the number of successes less than 2.5 or approximately less than 3.

Probability of less than 3 sucesses is

  P( X < 3 ) = P( X≤ 2 ) = P(X=0) + P( X = 1 ) + P( X = 2 )

                  = 2∑k=0 (k²⁰) [tex]( 20 )^{k} ( 1 - 0.4)^{20 - k}[/tex]

y  = 60 + 20x

where

y = costx = number of month

b.

The expression to represent the membership cost of Super Fit for x months is as follows:

y = 150 + 10x

c.

The membership period for them to pay the same amount can be calculated as follows:

60 + 20x = 150 + 10x

60 - 150 = 10x - 20x

-90 = -10x

x = 90 / 10

x = 9 months

Therefore, the period is 9 months
