Answer:

The coordinates of the point that divides the line segment in the ratio of 1:2 is (x,y)  =  (20/3 , 4)

Step-by-step explanation:

The end point coordinates of the  segment AB is A(9,3) and B(2,6)

Let us assume the point P(x,y) divides the segment AB in the ratio 1: 2

⇒AP : PB  = 1: 2

Now, by SECTION FORMULA:

If The point (x,y) divides the line segment with points (x1,y1) and (x2,y2) in the ratio m1: m2, then the coordinates of (x,y) is given as:

(x,y)  = ({\frac{x_2 m_1 + m_2 x_1}{m1 + m2} , \frac{y_2 m_1 + m_2 y_1}{m1 + m2} })

Applying the section formula in the given cindition,

here m1 :m2   = 1 :2

we get, (x,y)  = ({\frac{2(1) + 2(9) }{1 +2} , \frac{6(1)  + 2(3)}{1 + 2} })\\\implies (x,y)  = (\frac{2 + 18}{3} ,\frac{6 + 6}{3})\\ \implies (x,y) = (\frac{20}{3}, \frac{12}{3}  )

Now, comparing each ordinate separately

x  =    \frac{20}{3}       ,y  =  \frac{12}{3}  = 4

⇒ The coordinates of P(x,y)  =  (20/3 , 4)

Hence, the coordinates of the point that divides the line segment in the ratio of 1:2 is (x,y)  =  (20/3 , 4)

4

this is the answer because 2/3 out of 12 bloomed. 2/3 of 12 is 8. So 8 flowers bloomed. 1/2 of those were pink and 1/2 of 8 is 4. In conclusion, the answer is 4.

Help me out plesseee!!
nasty-shy [4]

Step-by-step explanation:

the rate of change is officially

(f(x2) - f(x1)) / (x2 - x1)

but for a line function (as we have here) this is totally easy : it is the slope of the line.

and that means it is the factor of x.

in our case this is -3/2.

because the slope of a line is the ratio "y coordinate change / x coordinate change". and that is exactly corresponding to the general rate of change definition above.

39 POINTS!! I NEED HELP ASAP!!!!!!! 2 QUESTIONS!!!!!
dangina [55]

Answer: 1) A = 28ft^{2}

2) 55 points

Step-by-step explanation:

1) A= 8w + 18, w=1.25

A = 8(1.25) + 18

A = 10 + 18

A = 28ft^2

2) 25 points to start with, additional 5 points per magazine they sell, m = number of magazines they sell

total points = 25 + 5m

How many if they sell 6?

total = 25 + 5(6)

= 25 + 30

total = 55

What is the square root of 175
ankoles [38]

the square root of a number is: one number times itself equals that number. Confusing '-' An example is the square of 4 is 2 because 2 times 2 = 4, or the square root of 56 is 8 because 8 times 8 is 64. The square root of 175 is about 13.22875 because 13.22875 times 13.22875 = about 175

To get an average, you must do the following steps.

step 1:add all the numbers together.
190258.50+152698.00+122753.00+220523.00+231951.00= 918183.5Step 2: divide the ANSWER you get by the amount of numbers there are:
(in this case, it will be 5, because you added 5 numbers together)
918183.5/5


your answer is: 183636.7
that is your average

hope this helps :D
