4. Given the points M(-3, -4) and T(5,0), find the coordinates of the point Q on directed line segment MT that partitions MT in

the ratio 2:3.
5. Points A,B and C are collinear on AC, and AB:BC = 3/4. A is located at (x,y), B is located at (4, 1) and C is located at (12, 5). What are the values of x and y?

Answer:

<u><em>4 : </em></u> Coordinate of Q = (\frac{1}{5} ,\frac{-12}{5} )

<em><u>5 : </u></em>  Coordinate of point A = (-2,-2)

Explanation :

4)  Given the points M(-3, -4) and T(5,0)

x₁= -3, y₁ = -4 and

x₂ = 5, y₂ = 0

m = 2, n = 1

Now apply the section formula,

{(mx₂+nx₁)/(m+n) , (my₂+ny₁)/(m+n)}

Coordinate of point Q = (\frac{1}{5} ,\frac{-12}{5} )


5)   AB:BC = 3:4

A = (x,y),   end point

B =  (4, 1)  

C = (12, 5)      end point

So, m = 3   &   n  = 4

x₁ = x ,  y₁ = y   , x₂=12  & y₂ = 5

Apply section formula we get

4 = (36+4x)/7                              &       1 = (15 + 4y)/7

28= 36 + 4x                                        7 = 4y + 15

4x =-8                                                         4y =-8

x =  -2                                                           y = -2

In the triangle below,
defon

Answer: y ≈ 10.6 cm

Step-by-step explanation:

The cosine function relates the adjacent side to the hypotenuse in a right triangle. The side adjacent to the 20° angle is 10 cm.

cos(20°) = (10 cm)/y

y = (10 cm)/cos(20°)

y ≈ 10.6 cm

The resale value of a certain car decreases over time. Use the line of best fit to estimate what the car will be worth in 7 year
Pie

Answer:

C. $5500

Step-by-step explanation:

Find the point on the horizontal scale where Time is 7. Follow that line up to the red "line of best fit". Then follow that horizontally to see where it falls on the Resale Value scale. It is between 5 and 6 (thousands of dollars) on that scale.

The only answer choice that is between $5000 and $6000 is ...

C. $5500
