Calculate the distance between the points G=(-9, 8) and C=(-1, 1) in the coordinate plane.
Give an exact answer (not a decimal approximation).

Answers

Answer 1

Answer:

10.63

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

01(x2-x1) = (-1 - -9) = 8

(y2-y1) = (1 - 8) = -7

Square the results and sum them up:

(8)2 + (-7)2 = 64 + 49 = 113

Now Find the square root and that's your result:

Exact solution: √113 = √113

Approximate solution: 10.6301

A sector with a radius of 6cm has a central angle measure 4pie/9 (in radius)

What is the area of the sector ?


Answers

Answer:

8πcm² = 8pi cm²

Step-by-step explanation

The formula for area of a sector = ½r²θ

Where r = radius = 6cm

θ = central angle = 4pi/9 in radians = 4π/9

Area of the sector = 1/2 × 6² × 4π/9

Area of the sector = (144π/18)cm²

Area of the sector = 8πcm²

Therefore, Area of the sector =

8πcm² = 8pi cm²

a perfect score in bowling is 300 points. you get a perfect score if you knock down 120 pins in 10 frames. what are the decimal value and percent of the number of pins knocked down in a relation to a perfect score?

Answers

Answer:

number of pins to perfect score

120/300=40/100

percent means parts out of 100

40/100=40%

answer is 40% or 0.40

NOTE: To find the percentage we will multiply decimal value of  number of know down pins to a perfect score by 100

Number of know down pins to a perfect score= 0.4 x 100

Number of know down pins to a perfect score=40%

A y=-3x+1
B x = 1/2x +7

Answers

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

= (2-4)/(-2+6)

= -2/4

= -1/2

now

y=mx+c

4=-1/2(-6)+c (you can take any x and y from the given two points. I took from (-6,4)

or,4= 3+c

therefore, c=1

now

y=mx+c

y= -1/2x+1

Chang made $156 for 13 hours of work at the same rate, how many hours would he have to work to make $108?

Answers

Answer:

  9 hours

Step-by-step explanation:

"At the same rate" means time and wages are proportional.

  time/wages = t/$108 = (13 h)/$156

  t = 108(13 h)/156 . . . . . . . . . . . . . . . units of dollars cancel

29. Martin has some dollar notes. 20% of the notes are $10 notes, 40% of
the remainder are $5 notes and the rest are $2 notes. He has a total
of $1026. How many notes does Martin have altogether?

Answers

Answer:

225 notes

Step-by-step explanation:

Let the number of notes is x.

20% of notes is:

0.2x

40% of the remainder is:

40% of 0.8x, so it is 0.8x*0.4 = 0.32x

Remaining notes are:

x - 0.2x - 0.32x = 0.48x

Total of the notes:

0.2x*10 + 0.32x*5 + 0.48x*2 = 10262x + 1.6x + 0.96x = 10264.56x = 1026x = 1026/4.56x = 225

[tex]\huge \bf༆ Answer ༄[/tex]

Step-by-step explanation:

Let's solve for x ~

[tex] \sf \dfrac{1}{3} {x}^{2} + x + \dfrac{5}{3} {x}^{2} = \dfrac{1}{9} [/tex]

[tex] \sf \dfrac{(1 + 5)}{3} {x}^{2} + x = \dfrac{1}{9} [/tex]

[tex] \sf \dfrac{6}{3} {x}^{2} + x - \dfrac{1}{9} = 0[/tex]

[tex] \sf2 {x}^{2} + x - \dfrac{1}{9} = 0[/tex]

Multiply each term with 9 on both sides of the equation

[tex] \sf(2 {x}^{2} \times 9) + (x \times9 ) - ( \dfrac{1}{9} \times 9 ) = 0 \times 9[/tex]

[tex] \sf18 {x}^{2} + 9x - 1 = 0[/tex]

Now, let's use Quadratic formula to find its roots ~

[tex] \sf \dfrac{ - {b}^{} \pm \sqrt{b {}^{2} - 4ac} }{2a} [/tex]

where,

b is Coefficient of x = 9

a is Coefficient of x² = 18

c is the constant term = -1

Let's find the roots ~

[tex] \sf \dfrac{ - 9 \pm \sqrt{(9 {}^{2}) - (4 \times 18 \times - 1) } }{2 \times 18} [/tex]

[tex] \sf \dfrac{ - 9 \pm \sqrt{81- ( - 72) } }{36} [/tex]

[tex] \sf \dfrac{ - 9 \pm \sqrt{81 + 72} }{36} [/tex]

[tex] \sf \dfrac{ - 9 \pm \sqrt{153} }{36} [/tex]

[tex] \sf \dfrac{ - 9 \pm 3\sqrt{17} }{36} [/tex]

[tex] \sf \dfrac{3( - 3 \pm \sqrt{17} )}{36}[/tex]

[tex] \sf \dfrac{ - 3 \pm \sqrt{17} }{12} [/tex]

Therefore the value if x are ~

Here are the graphs of L(x) and R(x) what are the values of L(2) and R(2)

Answers

Using the function graph given, it is found that:

L(2) = 7.R(2) = 1.

When a piece-wise function is given, that is, a function that has multiple definitions, the numeric value at x when the definition changes is given by the closed circle.

For function L(x), when x = 2, the closed circle is at y = 7, hence, L(2) = 7.For function R(x), when x = 2, the closed circle is at y = 1, hence, R(2) = 1.

Answer:

There is no difference

Step-by-step explanation:

The difference between the polynomials is 7y² + 8xy - 3

Polynomials are functions that have a degree of power greater than two.

According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)

f(x, y) = (7y^2 + 6xy) - (-2xy + 3)

f(x, y) = 7y² + 6xy + 2xy - 3

f(x, y) = 7y² + 8xy - 3

Hence the difference between the polynomials is 7y² + 8xy - 3
