The midpoint of line AC is
M(-1, 3). One endpoint is A(4, -1).
Find the coordinates of the other
endpoint C.
Step-by-step explanation:
Hey there!
Given;
Midpoint is (-1,3) and one endppint is; A(4,-1).
Let the coordinates of C be (x,y).
Use the midpoint formula.
[tex](x,y) = ( \frac{x1 + x2}{2} ,\frac{y1 + y2}{2} )[/tex]
Put all values.
[tex]( - 1,3) = (\frac{4 + x}{2} ,\frac{ - 1 + y}{2} )[/tex]
Since, they are equal, equating with their corresponding elements we get,
[tex] - 1 = \frac{4 + x}{2} [/tex]
Simplify it.
[tex] - 2 = 4 + x[/tex]
[tex]x = - 6[/tex]
Again,
[tex]3 = \frac{ - 1 + y}{2} [/tex]
Simplify it.
[tex]6 = - 1 + y[/tex]
[tex]y = 7[/tex]
Therefore the another endpoint is C(-6,7).
Hope it helps...

Step-by-step explanation:
3. A rocket is launched from a height of 3 meters with an initial velocity of 15 meters per second.
a. Model the situation with a quadratic equation.
b. What is the maximum height of the rocket? When will this occur?
c. What is the height of the rocket after four seconds? What does this mean?
d. When will the rocket hit the ground?
e. At what time will the rocket be 13 meters from the ground?
Let the rocket is launched at an angle of \theta with respect to the positive direction of the x-axis with an initial velocity u=15m/s.
Let the initial position of the rocked is at the origin of the cartesian coordinate system where the illustrative path of the rochet has been shown in the figure.
As per assumed sine convention, the physical quantities like displacement, velocity, acceleration, have been taken positively in the positive direction of the x and y-axis.
Let the point P(x,y) be the position of the rocket at any time instant t as shown.
Gravitational force is acting downward, so it will not change the horizontal component of the initial velocity, i.e. [tex]U_x=U cos\theta[/tex] is constant.
So, after time, t, the horizontal component of the position of the rocket is
[tex]x= U \cos\theta t \;\cdots(i)[/tex]
The vertical component of the velocity will vary as per the equation of laws of motion,
[tex]s=ut+\frac12at^2\;\cdots(ii)[/tex], where,s, u and a are the displacement, initial velocity, and acceleration of the object in the same direction.
(a) At instant position P(x,y):
The vertical component of the initial velocity is, [tex]U_y=U sin\theta[/tex].
Vertical displacement =y
So, s=y
Acceleration due to gravity is [tex]g=9.81 m/s^2[/tex] in the downward direction.
So, [tex]a=-g=-9.81 m/s^2[/tex] (as per sigh convention)
Now, from equation (ii),
[tex]y=U sin\theta t +\frac 12 (-9.81)t^2[/tex]
[tex]\Rightarrow y=U \sin\theta \times \frac {x}{U \cos\theta} +\frac 12 (-g)\times \left(\frac {x}{U \cos\theta} \right)^2[/tex]
[tex]\Rightarrow y=U^2 \tan\theta-\frac 1 2g U^2 \sec^2 \theta\;\cdots(iii)[/tex]
This is the required, quadratic equation, where [tex]U=15 m/s[/tex] and [tex]g=9.81 m/s^2[/tex].
(b) At the highest point the vertical velocity,v, of the rocket becomes zero.
From the law of motion, [tex]v=u+at[/tex]
[tex]\Rightarroe 0=U\sin\theta-gt[/tex]
[tex]\Rightarroe t=\frac{U\sin\theta}{g}\cdots(iv)[/tex]
The rocket will reach the maximum height at [tex]t= 1.53 \sin\theta s[/tex]
So, from equations (ii) and (iv), the maximum height, [tex]y_m[/tex] is
[tex]y_m=U\sin\theta\times \frac{U\sin\theta}{g}-\frac 12 g \left(\frac{U\sin\theta}{g}\right)^2[/tex]
[tex]\Rightarrow y_m=23 \sin\theta -11.5 \sin^2\theta[/tex]
In the case of vertical launch, [tex]\theta=90^{\circ}[/tex], and
[tex]\Rightarrow y_m=11.5 m[/tex] and [tex]t=1.53 s[/tex].
Height from the ground= 11.5+3=14.5 m.
(c) Height of rocket after t=4 s:
[tex]y=15 \sin\theta \times 4- \frac 12 (9.81)\times 4^2[/tex]
[tex]\Rightarrow y=15 \sin\theta-78.48[/tex]
[tex]\Rightarrow -63.48 m >y> 78.48[/tex]
This is the mathematical position of the graph shown which is below ground but there is the ground at [tex]y=-3m[/tex], so the rocket will be at the ground at t=4 s.
(d) The position of the ground is, y=-3m.
[tex]-3=U\sin\theta t-\frac 1 2 g t^2[/tex]
[tex]\Rightarrow 4.9 t^2-15 \sin\theta t-3=0[/tex]
Solving this for a vertical launch.
[tex]t=3.25 s[/tex] and [tex]t=-0.19 s[/tex] (neglecting the negative time)
So, the time to reach the ground is 3.25 s.
(e) Height from the ground is 13m, so, y=13-3=10 m
[tex]10=U\sin\theta t-\frac 1 2 g t^2[/tex]
Assume vertical launch,
[tex]4.9 t^2-15 \sin\theta t+10=0[/tex] [using equation (ii)]
[tex]\Rightarrow t=2.08 s[/tex] and [tex]t=0.98 s[/tex]
There are two times, one is when the rocket going upward and the other is when coming downward.

coordinates of B?
Answer:
(4,-4)
Step-by-step explanation:
let the coordinates of B be (x,y)
midpoint formula = (x1 +y1/2, x2 +y2\2)
(3,0) = (2+x\2),(4+y\2)
comparing we get
3=( 2+x\2), 0=( 4+y/2)
6= 2+ x 0=4+y
x= 4 y=-4

PLEASE HELP! A steel ball rolls with constant velocity across a tabletop that is 1.34 m tall. It rolls off and hits the ground .76 meters away from the table. How long was the ball in the air? (Show work)
How fast was the ball rolling across the table? (Show work)
Answer:
What forces act on the ball in the horizontal direction as it rolls? None. So that means there is no horizontal acceleration and therefore the horizontal component of the ball's speed is constant.
And since the ball was only travelling horizontally at the instant it rolled off the table, initially the vertical component of its speed is 0. That means the time taken to hit the ground after rolling off the table is the same as if it was just dropped 0.950 m. We can find this time using one of the kinematic equations of motion in the vertical direction, taking downwards as positive. Then we have the following information:
u = initial velocity = 0 m/s
d = distance fallen = 0.950 m
a = acceleration (due to gravity) = 9.8 m/s²
t = time = ?
d = ut + 1/2 at². Since u = 0 this reduces to d = 1/2 at² and rearranges to t = √(2d/a) = √(2*0.95/9.8) = 0.4403 s.
In the same amount of time, the ball travels a horizontal distance of 0.352 m. We already know the horizontal velcoity is constant, so horizontal velocity is just horizontal distance divided by time = (0.352 m)/(0.4403 s) = 0.799 m/s.

Raju went to the stationery shop to buy some pens and pencils. He bought two times as many pens as pencils. He spent Rs 52 in all. If a pen costs Rs 12 and a pencil Rs 2, how many pens did he buy?
Answer:
4 pens
Step-by-step explanation:
Let x represent the number of pens bought by Raju and y represent the number of pencils bought by Raju.
Given that Raju bought two times as many pens as pencils, this statement can be represented by:
x = 2y (1)
A pen costs Rs 12 and a pencil Rs 2, and he spent a total of Rs. 52, hence:
12x + 2y = 52 (2)
Substituting x = 2y in equation (2):
12(2y) + 2y = 52
24y + 2y = 52
26x = 52
y = 52/26
y = 2
From equation (1), x = 2y, hence:
x = 2(2)
x = 4
x = 4
Therefore he bought 4 pens and 2 pencils

A set of children’s blocks contains three shapes: long, flats, and cubes. There are three times as many longs as cubes and 30 fewer flats than longs. if there are 600 blocks in all how many Long’s are there
Answer:
There are 270 longs
Step-by-step explanation:
Equations
We must write the problem into a mathematical model that allows us to apply the properties of basic algebra and solve for the variable which must be adequately set up.
We have three unknowns: the number of long blocks, flats blocks, and cubes. The conditions are given:
There are three times as many longs as cubes There are 30 fewer flats than longs. There are 600 blocks in allFor the equation to be easier solved, let's set the variable as the number of cubes:
x = number of cubes
Considering the first condition, we have
3x = number of longs
3x-30 = number of flats
And finally:
[tex]x + 3x+3x-30=600[/tex]
Joining like terms:
[tex]7x=630[/tex]
Solving for x
[tex]\displaystyle x=\frac{630}{7}=90[/tex]
Therefore, there are 3x = 3*(90) = 270 longs
Answer: there are 270 longs
find the location of the midpoint of AB, given A(-8,-6) and B(-2,10)
Answer:
(- 5, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = A(- 8, - 6) and (x₂, y₂ ) = B(- 2, 10) , thus
midpoint = ( [tex]\frac{-8-2}{2}[/tex] , [tex]\frac{-6+10}{2}[/tex] ) = ([tex]\frac{-10}{2}[/tex] , [tex]\frac{4}{2}[/tex] ) = (- 5, 2 )
