Answer:

Did you mean 3.50x? If so, It would be (1.2, 2.2). If you meant just 3.50, it would be (1.56, 1.5)

Hope this helps!

The endpoints of ab are a(1,4) and b(6,-1). If point c divides ab in the ratio 2:3, the coordinates of c are ?. If point d divid

Pachacha [2.7K]

Answer:

The coordinate C:(3,2) and coordinate $D:\left ( \dfrac{11}{5},\dfrac{14}{5}, \right )$

Step-by-step explanation:

1. The endpoints of AB are A(1,4) and B(6,-1)

If point C divide AB in the ratio 2:3

Formula:

$\text{Section formula}(x,y)=\left ( \dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}, \right )$

Where,

$(x_1,y_1)\rightarrow A(1,4)$

$(x_2,y_2)\rightarrow B(6,-1)$

$m:n\rightarrow 2:3$

$C:(x,y)$

$C:\left ( \dfrac{2\cdot 6+3\cdot 1}{2+3},\dfrac{2\cdot -1+3\cdot 4}{2+3}, \right )$

$C:\left ( \dfrac{12+3}{5},\dfrac{-2+12}{5}, \right )$

$C:(3,2)$

2. The endpoints of AC are A(1,4) and B(3,2)

If point D divide AC in the ratio 3:2

$(x_1,y_1)\rightarrow A(1,4)$

$(x_2,y_2)\rightarrow C(3,2)$

$m:n\rightarrow 3:2$

$D:(x,y)$

$D:\left ( \dfrac{3\cdot 3+2\cdot 1}{2+3},\dfrac{3\cdot -1+2\cdot 4}{2+3}, \right )$

$D:\left ( \dfrac{9+2}{5},\dfrac{6+8}{5}, \right )$

$D:\left ( \dfrac{11}{5},\dfrac{14}{5}, \right )$

Hence, The coordinate C:(3,2) and coordinate D: $\left ( \dfrac{11}{5},\dfrac{14}{5}, \right )$

System of equations <br> Y=-1/2x+4 3x-4y=12

Kaylis [27]

Answer:

{x,y} = {8,3}

Step-by-step explanation:

// Solve equation [2] for the variable y

[2] 4y = 2x - 4

[2] y = x/2 - 1

// Plug this in for variable y in equation [1]

[1] 3x - 4•(x /2-1) = 12

[1] x = 8

// Solve equation [1] for the variable x

[1] x = 8

// By now we know this much :

x = 8

y = x/2-1

// Use the x value to solve for y

y = (/2)(8)-1 = 3

A tennis ball is moving 30 m/s toward a player who swings a racquet at a velocity of 15 m/s toward the ball. What is the velocit

algol13

Answer:

The velocity of the ball relative the racquet is 15 m/s.

Step-by-step explanation:

Given;

velocity of the tennis ball, $V_B$ = 30 m/s

Velocity of the racquet swung in opposite direction, $V_R$ = 15 m/s

The velocity of the ball relative the racquet ( $V_R_B$ ) is calculated as;

$V_R_B = V_B-V_R\\\\\V_{RB} = 30 \ m/s - 15 \ m/s\\\\V_{RB} = 15 \ m/s$

Therefore, the velocity of the ball relative the racquet is 15 m/s.
