Step-by-step explanation:  The prime factorization of  4320   is

  2•2•2•2•2•3•3•3•5  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 4320   =  √ 2•2•2•2•2•3•3•3•5   =2•2•3•√ 30   =

               ±  12 • √ 30

 √ 30   , rounded to 4 decimal digits, is   5.4772

So now we are looking at:

          w  =  ( -40 ± 12 •  5.477 ) / -34

Two real solutions:

w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757

or:

w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

The unit digit of the square of 572 is 4

Answer:

Step-by-step explanation:

opposite angles are equal

12x - 18 = 8x + 10

combine similar terms:

12x - 8x = 10 + 18

4x = 28

x = 28/4

x = 7

plugin the value of x=7 back into the equation to solve the angle

= 12x - 18

= 12(7) - 18

= 66

= 8x + 10

= 8(7) + 10

= 66

Answer:

172.2

Step-by-step explanation:

Answer:

113.8%

Step-by-step explanation:

let the unknown percentage be x%

hence we can re-write the given question as a mathematical equation

"What percent of 123 is 140" can be re-written mathematically as:

x% of 123 = 140

x/100 of 123 = 140

( x/100 )123 = 140   (multiply both sides by 100)

x(123) = 140 x 100

x(123) = 14000   (divide both sides by 123)

x = 14000 / 123

x = 113.8%

Answer:

I think it is 4:3

Step-by-step explanation:

From $960,000 take away $720,000 and you get $240,000 and that $960,000 divide by $240,000 and you get 4 and you do the same with $720,000 and you get 3

The requried ratio of candidate A's campaign spending to candidate B's campaign spending is 4 : 3.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
During a mayoral election, candidate A spent $960,000 on her campaign, and candidate B spent $720,000 on her campaign.

The ratio of candidate A's campaign spending to candidate B's campaign spending,

= 960000 / 720000

= 96 / 72
= 4 / 3

Thus, the requried ratio of candidate A's campaign spending to candidate B's campaign spending is 4 : 3.

Answer:

A function is defined as an equation in which no x value has two y values.  You can find the answer to this via the vertical line test.  If you move a pencil across a graph and it does not touch the graph at two points, then it is a function.  Utilizing this logic, the correct answer is yes, this is a function.

Step-by-step explanation:

Answer:

a)  P(X>=1) = 0,7293        or   P(X>=1) =  72,93 %

b)  P(X>=3) = 0,5686     or     P(X>=3) = 56,86 %

c)  y =  0,8494 mm³

d) λ = 1,69897 inc per mm³

Step-by-step explanation:

a) P(X>=1) = 1 - P(X=0)

P(X = 0) = λ⁰ * e∧⁻λ / 0!          where λ  = 2 in/mm³

P(X = 0) = e∧-2    ⇒    P(X = 0) = 0,2706

Then

P(X>=1) = 1 - 0,2706

P(X>=1) = 0,7293        or   P(X>=1) =  72,93 %

b) 3 inc. in 4 mm³ = 2*4/3     λ = 2,67 inc. per mm³

P(X>=3)  =  1 - P(X=1 ) - P(X=2)

P(X=1) = λ¹ * e∧-λ / 1!    ⇒  P(X=1) = 2,67 *e∧- 2,67/1

P(X=1) = 0,1846

P(X=2) = λ² * e∧-λ / 2!   ⇒   P(X=2) = (2,67)² * e ∧ - 2,67/2

P(X=2) = 7,1289* 0,06925/2     ⇒  P(X=2) = 0,2468

Then

P(X>=3)  =  1 -  0,1846 - 0,2468

P(X>=3) = 0,5686     or     P(X>=3) = 56,86 %

c) P(X>=1) = 0,98

and λ = 2*y     where y is the quantity of material

P(X=0) = 1 -  P(X>=1)

P(X=0) = 1 - 0,98    P(X=0) = 0,02

0,02 = (2*y)⁰  * e ∧ -2*y /0!

0,02 = 1 *  e ∧ -2*y

Taking log on both sides of the equation

log (0,02) = -2*y        - 1,69897 = - 2*y

y =  0,8494 mm³

d) P(X  >=1 ) = 1 - P( X = 0)

0,98 = 1 - P( X = 0)

P( X = 0) = 0,02

0,02 = λ⁰ * e ∧ - λ / 0!

0,02 = e ∧ -λ

Taking log on both sides of the equation we get:

log ( 0,02 ) = - λ

- 1,69897  =  - λ

λ = 1,69897  inc. per mm³

b = 387

Step-by-step explanation:

1057 - 670 = 387

First isolate B by putting the 670 to the other side of the equal sign. However, in order for the equation to remain equal, you must subtract 670 from both sides.

1057 - 670 = B + 670 - 670

387 = B

Answer:

No, because one x-value corresponds to two different y-values ⇒ D

Step-by-step explanation:

The relation of x and y can be a function if every x has only one value of y (x not repeated)

Examples:

Let us check the given table

∵ At x = 2, y = 1

∵ At x = 3, y = 4

∵ At x = 4, y = 4

∵ At x = 5, y = 2

∵ At x = 5, y = 5

∵ x = 5 has two values of y 2 and 5

→ That means x is repeated

∴ Not every x has only one value of y

∴ The table does not represent a function

∴ The right answer is D

Answer:

We have to find the equation of the red line

To get the equation of the line in the slope-intercept form,

we need its slope and its y-intercept

Finding the Slope

we know that the slope of a line is the rise of the line / run of the line between 2 points

here, the 2 points are already marked on the graph

So, slope = rise / run

we notice that the line rises only 2 units and runs 8 units between the points: (-5 , 3 ) and (3 , 5)

Slope = rise  / run

now that we know the values of rise and run, we can plug the values to get the slope

Slope  = 2 / 8

Slope = 1 / 4

Finding the y-intercept

We will now look at the point (-5 , 3) , we know that the slope is 1/4.

which means that every time the line moves 1 unit to the right, it also moves 1/4 units up

So, until the point (-1 , 4), the line has finally ascended 1 unit and now is at a proper coordinate

We can see that the line is only 1 unit to the left of the y-axis, so the y-coordinate of the line after moving 1 unit to the right is the y-intercept

since the line ascends 1/4 units every time it moves 1 unit to the right,

the ordinate of the line at the y-axis will be 1/4 more than the last ordinate (which was 4)

y-intercept = (4 + 1/4)

y-intercept = 17 / 4

Equation of the line

From the question, we know that the general form of the slope-intercept form is :

y  = mx + b (where m is the slope and b is the y-intercept)

y = (1/4)x + (14/4)

y = (x + 14) / 4
