Answer:

RP/SP =3 , RP/RS = 3/4

Step-by-step explanation:

Here is the complete question

Three colinear points on the coordinate plane are R(x,y) S(x+8h, y+8k) and P(x+6h,y+6k) Determine value of RP/SP and RP/RS?

Solution

We first find the length of RS, SP and RP as follows

RS = S(x+8h, y+8k)  - R(x,y)

= √[((x + 8h) - x)² + ((y + 8k) - y)²]

= √[x - x + 8h)² + (y - y + 8k)²]

= √[(8h)² + (8k)²] = 8√(h² + k²)

SP = P(x + 6h,y + 6k) - S(x+8h, y+8k)  

= √[((x + 6h) - (x + 8h))² + ((y + 6h) - (y + 8k))²]

= √[x - x + 6h - 8h)² + (y - y + 6k - 8k)²]

= √[(-2h)² + (-2k)²] = 2√(h² + k²)

RP = P(x+6h, y+6k)  - R(x,y)

= √[((x + 6h) - x)² + ((y + 6k) - y)²]

= √[x - x + 6h)² + (y - y + 6k)²]

= √[(6h)² + (6k)²] = 6√(h² + k²)

So, RP/SP = 6√(h² + k²)/2√(h² + k²)

= 6/2

= 3

RP/RS = 6√(h² + k²)/8√(h² + k²)

= 6/8

= 3/4

2x+112=180

2x=68

x=34

Let me know if this helps :)

Answer:

34 degrees

Step-by-step explanation:

(2x+9) degrees and 103 degrees  form a linear pair

Therfore, the sum of these two angles = 180

(2x+9)+103=180

=>2x+112=180

=>2x=180-112

=>2x=68

=>x=68/2

=>x=34

The value of x is 34 degrees

Hey there!

60x=360

x=6

Let me know if this helps :)

Hi there! :)

Answer:

Formula: 60t = 360

Solved: t = 6 hours.

Given:

Speed of car = 60 mph

Total distance = 360 miles

Remember, the formula to solve for time (t) given distance (d) and speed (s)  is t = d / s, or t · s = d.

Substitute in the known values, and let "t" represent the time needed:

60 · t = 360

Solve:

60t/60 = 360/60

t = 6 hours.

Answer:

m<ABC = 45

m<DBC = 34°

Step-by-step explanation:

Given:

m<ABD = 79°

m<ABC = (8x - 3)°

m<DBC = (5x + 4)°

Step 1: Generate an equation to find the value of x

m<ABC + m<DBC = m<ABD (angle addition postulate)

(8x - 3) + (5x + 4) = 79

Solve for x

8x - 3 + 5x + 4 = 79

13x + 1 = 79

Subtract 1 from both sides

13x + 1 - 1 = 79 - 1

13x = 78

Divide both sides by 13

x = 6

Step 2: find m<ABC and m<DBC by plugging the value of x into the expression of each angle

m<ABC = (8x - 3)°

m<ABC = 8(6) - 3 = 48 - 3 = 45°

m<DBC = (5x + 4)°

m<DBC = 5(6) + 4 = 30 + 4 = 34°

Answer:

  -2x^3 +13x^2 +3x -54

Step-by-step explanation:

The product is found using the distributive property.

  (x -6)(-2x^2 +x +9) = x(-2x^2 +x +9) -6(-2x^2 +x +9)

  = -2x^3 +x^2 +9x +12x^2 -6x -54

  = -2x^3 +13x^2 +3x -54

Answer:

P(t) = 258( 1 + 6%)^t

Step-by-step explanation:

Given that the  population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, the function representing the number of caribou in the forest in t years will be

P(t) = 258( 1 + 6%)^t

Since it is increasing, it will be 1 + 6%

Where P(t) is the function representing the population after t years.

258 is the current or initial population.

and so on.

These fractions are equivalent to 1/2 because they represent the same value when simplified.

When the numerator and denominator are divided by their greatest common divisor, they result in the simplified fraction of 1/2.

For example, if we simplify 2/4, we divide both the numerator and denominator by 2, resulting in 1/2

Similarly, if we simplify 6/12, we divide both the numerator and denominator by 6, again resulting in 1/2. This pattern holds for all the listed fractions.

This is a graph problem

Step-by-step explanation:

on a ten by ten graph this is the included file

(sorry for my bad lines, i had to do this with a mouse0

Answer:

  see the attachment for a graph

Step-by-step explanation:

We can't tell what your instructions are. Many graphing tools will let you click on the locations of the points, then draw a line through them. The attached image is from one such tool.

__

If you want to plot this by hand, you do it essentially the same way: plot the two points and draw a line through them.

If you want to write an equation for the line, you can start with the 2-point form:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (5 -(-3))/(2 -(-4))(x -(-4)) -3

  y = 8/6(x +4) -3

  y = 4/3x +16/3 -9/3

  y = 4/3x +7/3

__

Personally, about the only thing useful I find in this equation is that it tells you the slope is 4/3. You can determine the same thing by counting grid squares between the plotted points on the graph. The line goes up 8 for each 6 to the right, so slope = rise/run = 8/6 = 4/3.

Answer:

If statement(1) holds true, it is correct that [tex]\small \frac{r}{s}[/tex] is an integer.

If statement(2) holds true, it is not necessarily correct that [tex]\small \frac{r}{s}[/tex] is an integer.

Step-by-step explanation:

Given two positive integers [tex]r[/tex] and [tex]s[/tex].

To check whether [tex]\small \frac{r}{s}[/tex] is an integer:

Condition (1):

Every factor of [tex]s[/tex] is also a factor of [tex]r[/tex].

[tex]r \geq s[/tex]

Let us consider an example:

[tex]s = 5^2 \cdot 2\\r = 5^3 \cdot 2^2[/tex]

[tex]\dfrac{r}{s} = \dfrac{5^3\cdot2^2}{5^2\cdot2} = 10[/tex]

which is an integer.

Actually, in this situation [tex]s[/tex] is a factor of [tex]r[/tex].

Condition 2:

Every prime factor of s is also a prime factor of r.

(But the powers of prime factors need not be equal as we are not given the conditions related to powers of prime factors.)

Let

[tex]r = 2^2\cdot 5\\s =2^4\cdot 5[/tex]

[tex]\dfrac{r}{s} = \dfrac{2^3\cdot5}{2^4\cdot5} = \dfrac{1}{2}[/tex]

which is not an integer.

So, the answer is:

If statement(1) holds true, it is correct that [tex]\small \frac{r}{s}[/tex] is an integer.

If statement(2) holds true, it is not necessarily correct that [tex]\small \frac{r}{s}[/tex] is an integer.

Answer:

18.6

Step-by-step explanation:

Adding -20.4 to 39 is the same as subtracting 20.4 from 39. 39 - 20.4 = 18.6.

Answer:

See each problem number below for answers.

Step-by-step explanation:

To solve this problem, we must remember the rules of addition and subtraction.  If we are adding a negative, this is the same thing as subtracting a positive number (because subtraction is defined as the addition of a negative number).  In addition, if we are subtracting a negative number, the two negative signs cancel each other out, and we are left with addition of a positive number.  Let's use these rules in the problems you have given.

1) 2 - (-73)

Since the subtraction of a negative is the same as addition, we can rewrite this as:

2 + 73

which is a simple computation and leaves us with:

75

2) 39 + (-20.4)

The addition of a negative is the same as subtraction, so we can rewrite this as:

39 - 20.4

which is a simple computation and yields:

18.6

3) 67.086 - (-20)

The subtraction of a negative is the same as addition (similar to problem 1)

67.086 + 20 = 87.086

4) 60 + (-19)

The addition of a negative is the same as subtraction (similar to problem 2)

60 - 19 = 41

5) 87 - 64.05

This is a simple subtraction problem, the computation gives us the answer of:

87 - 64.05 = 22.95

Step-by-step explanation:

x + y = 16 (*)

x^2 + y^2 = 146 (**)

(*) <=> x= 16-y

substitute x = 16 - y

(**) <=> (16-y)^2 + y^2 = 146

<=> y^2 - 2.16.y + 16^2 + y^2 = 146

<=> 2y^2 - 32y + 110 = 0

<=> y^2 - 16y + 55 = 0

<=> (y-11)(y-5) = 0

<=> y=11 or y= 5

For y = 11, we have x= 16-11=5
