Answer:

is this algebra

Step-by-step explanation:

Answer 2

Answer:

1.)

A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.

Slope calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]

B.) The coordinate (0,0) represents that no laps have been completed nor has the time started

C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes

2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.

Slope Calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]

3.)

A.) The constant of proportionality is 7/4 or 1.75

B.) y = 7/4x

4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene, equilateral, isosceles, and right angled triangle.

Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.

Since Quadrilateral HIJK is similar to quadrilateral LMNO, therefore the ratio of their corresponding sides is equal to each other. Hence:

[tex]\frac{OL}{HK}=\frac{ON}{KJ}\\\\substituting:\\\\\frac{OL}{42}=\frac{58}{19} \\\\OL=\frac{58*42}{19} \\\\OL=128.2[/tex]

The sum of the interior angles of each polygon is 360°. In the diagram ABCD=HGEF find the values of x and y look at photo below

Answers

Answer:

x = 3

y = 60°

Step-by-step explanation:

The given parameters of the figures are;

The sum of the interior angles of each polygon (quadrilaterals) = 360°

Quadrilateral ABCD = Quadrilateral HGEF

∴ ABCD ≅ HGEF

Therefore;

Segment AB ≅ Segment HG, by Corresponding Sides of congruent polygons are congruent

∴ The length of segment AB = 3 ft. = The length of segment HG = x ft.

∴ 3 ft. = x ft.

x = 3

Similarly, we have;

∠A + ∠B + ∠C + ∠D = 360° Given

∠B = 100°, and ∠D = 70° Given

∴ ∠A + ∠C = 360° - (∠B + ∠D) = 360° - (100° + 70°) = 190°

∠A + ∠C = 190°

∠A ≅ ∠G and ∠C ≅ ∠E Corresponding angles of congruent polygons are congruent

∴ ∠A = ∠G and ∠C = ∠E By definition of congruency

∴ ∠A + ∠C = ∠G + ∠E = 190° by transitive property

∠G = (2·y + 2)°, and ∠E = (y + 8)° Given

∴ ∠G + ∠E = (2·y + 2)° + (y + 8)° = (3·y + 10)° = 190°

3·y = 190° - 10° = 180°

y = 180°/3 = 60°

y = 60°

The value of x and y are 3 feet and 72 degrees respectively

Angle in a quadrilateral.

From the given quadrilaterals, the sum of adjacent angles is 180 degrees.

Hence from figure;

m<E + m<F = 180m<B = m<F = 100

y + 8 + 100 = 180

y + 108 = 180

y = 180 - 108

y = 72degrees

Similarly;

m<D = mG = 70 degrees.

AB = GH = 3 feet

Hence the value of x and y are 3 feet and 72 degrees respectively

Rebecca ran 21 miles in 5 hours. If she ran at a constant speed, how many miles did she run in 2 hours? 8.4 miles 42 miles 4.2 miles 1.2 miles

Answers

Answer: 8.4 miles

Step-by-step explanation:

d = rt

Solve for her rate

21 = 5r

r = 21/5

r = 4.2

Solve for if the time is 2 hours and rate (solved previously) is 4.2

d = 4.2*2

d = 8.4

The distance traveled by Rebecca in 2 hours is given by d = 8.4 miles and the speed is S = 4.2 miles / hour

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the total distance ran by Rebecca be D = 21 miles

The time taken by her to travel 21 miles T = 5 hours

So , the speed of Rebecca S = D / T

On simplifying , we get

S = 21/5

S = 4.2 miles per hour

Therefore , the speed of Rebecca is 4.2 miles / hour

Now , let the time taken be T₂ = 2 hours

So , the distance traveled in 2 hours , D = ST₂

D = 4.2 x 2

D = 8.4 miles

Hence , the distance traveled is 8.4 miles

Find the value of x.

Answers

Answer: x = 20

Step-by-step explanation:

The angle is 90 degrees so we can make an equation

with it.

3x + 10 + x = 90

Combine like terms

4x + 10 = 90

subtract 10 from both sides to cancel it out

4x = 80

Now divide by 4 to leave x by itself

x = 20

Now you can check if it's correct by plugging in x to the equation given

3(20) + 10

60 + 10

70

20 + 70 = 90 degrees

Answer:

D: 20 degrees

Step-by-step explanation:

First, we add 3x+10 and x together because they are within a right angle, which is 90 degrees. This gives the equation 4x+10=90. We solve from here.

We subtract 10 from both sides to isolate the x-variable. 90 minus 10 equals 80. This gives us the equation 4x=80. To further isolate the x-variable, we divide both sides by 4. 80 divided by 4 equals 20.

This leaves us with x=20.

Put together, Dulcina and Tremaine have 129 total matchbooks. Tremaine's collection has 39 fewer matchbooks in it than Dulcina's collection. How many matchbooks are in Tremaine's collection? How many matchbooks are in Dulcina's collection?

Answers

Answer:

Let the Dulcina's collection be 'x'

Let the Tremaine collection be 'x-39'

x + x - 39 =129

2x = 129 +39

2x = 168

x = 168/2

x = 84

Dulcina's collection = x = 84

Tremaine's collection = x - 39 = 84 - 39 = 45

how to find imaginary zeros anf real zeros of F(x)=-4x^5-8x^3+12x​

Answers

Answer:

[tex]x=\{0, -1, 1, -i\sqrt{3}, i\sqrt{3}\}[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=-4x^5-8x^3+12x[/tex]

And we want to finds its zeros.

Therefore:

[tex]0=-4x^5-8x^3+12x[/tex]

Firstly, we can divide everything by -4:

[tex]0=x^5+2x^3-3x[/tex]

Factor out an x:

[tex]0=x(x^4+2x^2-3)[/tex]

This is in quadratic form. For simplicity, we can let:

[tex]u=x^2[/tex]

Then by substitution:

[tex]0=x(u^2+2u-3)[/tex]

Factor:

[tex]0=x(u+3)(u-1)[/tex]

Substitute back:

[tex]0=x(x^2+3)(x^2-1)[/tex]

By the Zero Product Property:

[tex]x=0\text{ and } x^2+3=0\text{ and } x^2-1=0[/tex]

Solving for each case:

[tex]x=0\text{ and } x=\pm\sqrt{-3}\text{ and } x=\pm\sqrt{1}[/tex]

Therefore, our real and complex zeros are:

x^2 + 10x = -9
