Answer:

-4

Step-by-step explanation:

We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.

The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.

We have the gradient, so we can put it in the equation:

y = x/2 + c

We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.

3 = 6/2 + c

3 = 3 + c

c = 0

Therefore the equation for our line is y = x/2.

We can now put in the y coordinate we were given to work out the corresponding x coordinate:

-2 = x/2

x = -4

Therefore n is -4.

Supposed you were standing beneath a palm tree when a coconut began to fall. If the height of the coconut is 64 feet, how much t

larisa [96]

Answer:

t = 1.41 seconds

Step-by-step explanation:

We know the height at which the coconut is, which is 64 ft, now assuming that we are on the ground, we know that gravity is equal to 32.1742 ft / s².

Gravity is an acceleration, we have that the acceleration is equal to:

a = v / t

but the speed v = d / t, replacing we have:

a = (d / t) / t

That is to say

a = d / t²

Now, solved for you we have:

t = (d / a) ^ (1/2)

Replacing the values, we are left with:

t = (64 / 32.17) ^ (1/2)

t = 1.41 seconds

therefore, the person has 1.41 seconds to escape.

Find the coordinates of the endpoint A given B (-3,5) is the midpoint of AC and C (1,-2)

WARRIOR [948]

coordinates of endpoint A are (-7,12)

Step-by-step explanation:

We are given midpoint B (x,y) =(-3,5)

One endpoint C (x₂,y₂)= (1,-2)

We need to find other endpoint A (x₁,y₁).

The formula to find midpoint is:

$x=\frac{x_{1}+x_{2}}{2}\\y=\frac{y_{1}+y_{2}}{2}$

We can find the coordinates of endpoint A using these formula.

We have x=-3, x₁=? and x₂= 1

Putting values and finding x₁

$x=\frac{x_{1}+x_{2}}{2}\\-3=\frac{x_{1}+1}{2}\\-6=x_{1}+1\\-6-1=x_{1}\\x_{1}=-7$

Now, y=5, y₁=? and y₂= -2

$y=\frac{y_{1}+y_{2}}{2}\\5=\frac{y_{1}+-2}{2}\\5*2=y_{1}+-2\\10=y_{1}+-2\\10+2=y_{1}\\y_{1}=12$

SO, coordinates of endpoint A are (-7,12)

Please help I'll give brilliantist:)

Vanyuwa [196]

Answer:

(-3, -6)

Step-by-step explanation:

Coordinate = (x-axis, y-axis)

=(x,y)

identify value of coordinate A at x-axis before y-axis

x-axis of A is in the middle of -2 and -4, thus it is -3

y-axis of A when refer to graph is -6

thus answer is (-3,-6)
