On a coordinate plane, a line is drawn from point C to point D. Point C is at (negative 1, 4) and point D is at (2, 0). Point C
skelet666 [1.2K]

Answer:

distance = 5 units

Step-by-step explanation:

In order to solve this problem we can start by plotting the two points you were provided with (see attached picture). This will help us visualize the problem better.

Now, we need to find the distance between those two points, so in order to do so we can use the distance formula:

distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

in this case the x's and y's are given by the given points, since they are written as ordere pairs. And ordered pairs are written in the form (x,y). So for Point C:

C=(-1,4)

x_{1}=-1

y_{1}=4

and for point D

D=(2.0)

x_{2}=2

y_{2}=0

so we can now use those values in our distance formula so we get:

d=\sqrt{(2-(-1))^{2}+(0-4)^{2}}

d=\sqrt{(3)^{2}+(-4)^{2}}

d=\sqrt{9+16}

d=\sqrt{25}

d=5 units.

Express parametrically a point on a parabola (y-1) ssquare=x
sdas [7]

Answer:

Conversely, given a pair of parametric equations with parameter t, the set of points (f(t), g(t)) form a curve in the plane.

As an example, the graph of any function can be parameterized. For, if y = f(x) then let t = x so that

x = t,   y = f(t).

is a pair of parametric equations with parameter t whose graph is identical to that of the function. The domain of the parametric equations is the same as the domain of f.

Example The parametric equations

x = t,   y = t2

Xavier climbs 9ft up into an apple tree what integer represents the directions and how far he will climb to get back down to the
masha68 [24]

Answer:

<h2>Direction is represented by +9, indicating that is moving in a positive direction (upwards).</h2><h2>Zero is the reference point.</h2>

Step-by-step explanation:

So, basically, we need to apply a reference system to express directions, because all movements are represented respect to a reference point. In this case, number zero represents that reference point, which is located in the ground, setting this reference point we can measure the distance that Xavier traveled upwards the apple tree.
