Answers

Answer 1

Answer:

2

Step-by-step explanation:

Given the quadratic equation

3x²+2x-1=0

Let tthe root be α and β

Sum of root α+β = -b/a

Product of root αβ = c/a

Given that;

a = 3, b = 2 and c = -1

α+β = -2/3

αβ = -1/3

To get 1/α + 1/β

Find the LCM

1/α + 1/β

= (α+β)/αβ

= (-2/3)/(-1/3)

= -2/3 * 3/-1

=  2

Hence the required answer  is 2

Find the value of x on a triangle

Answers

Answer:

x = 25

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

90 + x+ 2x+15 =180

Combine like terms

105+3x = 180

Subtract 105 from each side

105+3x-105 = 180-105

3x =75

Divide each side by 3

3x/3 = 75/3

x = 25

Answer:

25°

Step-by-step explanation:

2x + 15° + x + 90 °= 180° ( being sum of angles of triangle)3x + 105° = 180 °3x = 180 °- 105°3x = 75° x = 25°hope it helps :)

Tiana uploaded 150 songs from her computer to her cell phone. These songs took up 300
megabytes of space on her phone. Each song took up the same amount of space.
How many megabytes do 25 of these songs take up?

Answers

Answer:

50mb

Step-by-step explanation:

So start with what you have 300/150 = 2 so each song took up 2mb of space, so 25 songs would take up 25x2= 50mb

The number of megabytes taken up by 25 songs is 50 megabytes.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

150 songs = 300 megabytes

1 song = 300 /150 megabytes

1 song = 2 megabytes ______(1)

Now,

Multiply 25 on both sides of (1).

25 songs = 25 x 2 megabytes

25 songs = 50 megabytes

Thus,

25 songs will take 50 megabytes.

What is the equation for the lines that passes through the coordinates (2,7) and (0,1)

Answers

Answer:

(x1,y1)   is  (2,7)

    (x2,y2)   is  (0,1)

Step-by-step explanation:

Point-slope form is:

 

  (y-y1) = ( (y2-y1) / (x2-x1) )(x - x1)

 

   y - 7 =( (-6)/(0-2) )(x-2)

   y - 7 = 3x - 6

    y = 3x + 1    [slope-intercept form]

Check:

  Is  (2,7) on the line:

       7 = 3(2) + 1   ?

       y = 7   ?yes

  Is (0,1) on the line:

       1 = 3(0) + 1   ?

       1 = 1   ? yes

Answer:

y=3x+1

to find the slope, find the change in y/change in x

7-1=6

2-0=2

6/2=3

3 is your slope

your y intercept occurs when x=0, and that was given to you in the problem

(0,1)

your y int is 1

Polygon A has an area of 18 square feet and Polygon B has an area of 98 square feet. If the two polygons are similar, and Polygon B has a side length of 14 feet, find the corresponding side length in Polygon A.

Answers

Answer:

6 feet

Step-by-step explanation:

Let the length of side length in polygon A be represented by x. Since the two polygons are similar, then it can be deduced that;

Area scale factor = [tex](linear scale factor)^{2}[/tex]

linear scale factor = [tex]\sqrt{Area scale factor}[/tex]

Area scale factor = [tex]\frac{98}{18}[/tex]

So that,

linear scale factor = [tex]\sqrt{\frac{98}{18} }[/tex]

                              = 2.3333

The length of side of polygon A = [tex]\frac{14}{2.3333}[/tex]

                                       = 6.0085

Therefore, the corresponding side length of polygon A is 6 feet.
