Answer:

The two ordered pairs you can use is (4, 3) and (8, 4). You can plot these and draw a straight line through these.

Step-by-step explanation:

In order to find the graph of the follow, first solve for y.

-8 + x = 4y - 16

-4y - 8 + x = -16

-4y -8 = -x - 16

-4y = -x - 8

y = 1/4x + 2

Now that we have this, we can find two points by choosing any two x's and solving for the y. For this case, we'll use 4 and 8.

y = 1/4x + 2

y = 1/4(4) + 2

y = 1 + 2

y = 3

So the first ordered pair is (4,3)

y = 1/4x + 2

y = 1/4(8) + 2

y = 2 + 2

y = 4

So the second would be (8. 4)

Write the equation of the conic section satisfying the given conditions. focus at the pole, e = 3/4, horizontal directrix 2 unit

hjlf

Answer:

The equation in the polar form is;

$r = \dfrac{6}{4 + 3 \cdot sin(\theta)}$

Step-by-step explanation:

e = 3/4 > 1, we have an hyperbola

The polar equation of a conic is of the form;

For vertical directrix

$r = \dfrac{k \cdot e}{1\pm e \cdot cos (\theta)}$

For horizontal directrix

$r = \dfrac{k \cdot e}{1\pm e \cdot sin(\theta)}$

Where;

k = Distance from the focus to the directrix = 2

We have;

$r = \dfrac{2 \cdot \dfrac{3}{4} }{1 + \dfrac{3}{4} \cdot sin(\theta)}$

$r = \dfrac{\dfrac{3}{2} }{1 + \dfrac{3}{4} \cdot sin(\theta)}$

Which gives the equation in the polar form as follows;

$r = \dfrac{6}{4 + 3 \cdot sin(\theta)}$ .

PLEASE HELP!!!

We have to calculate the length of stack RM. This is a pyramid with a rectangular base. If TS = 12 cm, then OM = TS / 2 = 12 / 2 = 6 cm. And since we already know that RO = 15 cm, we will use the Pythagorean theorem: RM^2 = 15^2 + 6^2; RM^2 = 225 + 36 = 261; RM = sqrt ( 261 ) ; RM = 16.1555 ( or 16.2 rounded to the nearest tenth ). Answer: RM = 16.2 cm<span>.</span>
