Suppose A, R, and B are collinear on AB, and AR:AB= 1/5. What are the coordinates of R?

AfilCa [17]

Answer:

R(1.6, 0)

Step-by-step explanation:

Use the formula, $(x, y) = (x_1 + k(x_2 - x_1), y_1 + k(y_2 - y_1))$ to find the coordinates of point R, that partition the lie segment AB into the ratio 1/5.

Let,

$A(1, -1) = (x_1, y_1)$

$B(4, 4) = (x_2, y_2)$

Thus, plug in the values as follows:

$R(x, y) = (1 + \frac{1}{5}(4 - 1), -1 + \frac{1}{5}(4 -(-1))$

$R(x, y) = (1 + \frac{1}{5}(3), -1 + \frac{1}{5}(4 + 1)$

$R(x, y) = (1 + \frac{1}{5}(3), -1 + \frac{1}{5}(5)$

$R(x, y) = (1 + \frac{3}{5}, -1 + \frac{5}{5})$

$R(x, y) = (\frac{5 + 3}{5}, -1 + 1)$

$R(x, y) = (\frac{8}{5}, 0)$

$R(x, y) = (1.6, 0)$

The coordinates of point R, are (1.6, 0)

Can someone please answer this!!!!

alexandr402 [8]

Step-by-step explanation:

$\frac{y}{20 \sqrt{3} } = \sin(30)$

$y = 20 \sqrt{3} \times \frac{1}{2}$

$y = 10 \sqrt{3}$

$\frac{x}{20 \sqrt{3} } = \cos(30)$

$x = 20 \sqrt{3} \times \frac{ \sqrt{3} }{2}$

$x = 30$

option D, x=30 and y = 10√3

Ugo [173]

Answer:

True

Step-by-step explanation:

Given that

The mean is 36

And, the standard deviation is 10

We take the sample of 16 individuals and the same would be randomly chosen

We need to find out that whether the given statement is true or false

So,

The given statement is true as the random variable means the average percent that could be consumed each day by a person
