The midpoint of the line segment from P1 to P2 is (-6,5). If P1 = (-7,8), what is P2?
kipiarov [429]
You can determine midpoint by
x-midpoint = (x₁ + x₂)/2
y-midpoint = (y₁ + y₂)/2

Given from the question
x-midpoint = -6
x₁ = -7
y-midpoint = 5
y₁ = 8

Asked from the question
(x₂, y₂)

Solution
Find x₂, input the value of x₁ and x-midpoint to the formula
(x₁ + x₂)/2 = x-midpoint
(-7 + x₂)/2 = -6
-7 + x₂ = -6 × 2
-7 + x₂ = -12
x₂ = -12 + 7
x₂ = -5

Find y₂, input the value of y₁ and y-midpoint to the formula
(y₁ + y₂)/2 = 5
(8 + y₂)/2 = 5
8 + y₂ = 5 × 2
8 + y₂ = 10
y₂ = 10 - 8
y₂ = 2

Answer
P₂ = (-5,2)

Answer:84

Step-by-step explanation:

Okay. Are you taking calc? Dv/dt =d/dt(L(t)^3)=d/dt[(sqrt(14)+2t)^3]= 6(Sqrt(14)+2t)^2)=44. We defined t=0 to be time at which length is sqrt(14). Does that work?

10. Make Sense and Persevere The flag of the
kumpel [21]

Answer:

  • s=\frac{P}{3}
  • Dimensions of the flag:

       lenght=6.65\ ft\\\\width=3.5\ ft

  • Area of the flag: 23.275\ ft^2

Step-by-step explanation:

<em><u>The missing figure of the exercise is attached.</u></em>

<em><u /></em>

We know that the perimeter of the triangle is given by:

P= 3s

Where "s" is the side lenght of the triangle.

Solving for "s", we get:

s=\frac{P}{3}

Therefore, if the perimeter of the triangle is 126 inches, its side length is:

s=\frac{126\ in}{3}\\\\s=42\ in

 Since  1\ ft=12\ in, we know that "s" in feet is:

s=(42\ in)(\frac{1\ ft}{12\ in})=3.5\ ft

The area of a rectangle can be calculated with this formula:

A=lw

Where "l" is the lenght and "w" is the width

We can observe in the figure that the lenght and the width of the flag are:

l=1.9s\\w=s

Then, the dimensions of the flag are:

l=1.9(3.5\ ft)=6.65\ ft\\w=3.5\ ft

And the area is:

A=(6.65\ ft)(3.5\ ft)=23.275\ ft^2
