What are the endpoint coordinates for the midsegment of △BCD that is parallel to BC?
natulia [17]

Answer:

<em>The endpoint coordinates for the mid-segment are:  (-2,-1) and (1,0)</em>

Step-by-step explanation:

According to the given diagram, the coordinates of the vertices of \triangle BCD are:   B(-3,1), C(3,3) and D(-1,-3)

Now, the endpoints of the mid-segment of \triangle BCD which is parallel to BC will be the mid-points of sides BD and CD.

<u>Formula for the coordinate of mid-point</u> :   (\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}), where (x_{1}, y_{1}) and (x_{2}, y_{2}) are two endpoints.

So, the mid-point of BD will be:  (\frac{-3-1}{2},\frac{1-3}{2})=(\frac{-4}{2},\frac{-2}{2})=(-2,-1)

and the mid-point of CD will be:  (\frac{3-1}{2},\frac{3-3}{2})=(\frac{2}{2},\frac{0}{2})=(1,0)

Thus, the endpoint coordinates for the mid-segment of \triangle BCD that is parallel to BC are  (-2,-1) and (1,0)

How can i solve thus problem help me ​
Serjik [45]

Answer:

Position from point A= 383.33 meters

Step-by-step explanation:

A concept to know is that the integral of velocity will give you the distance traveled.

d=\int\limits^{t_1}_{t_0}{v(t)} \, dt

where the interval of integration are the starting time and ending time.

I let the starting time be t₀ = 0, and the ending time t₁=10 for the 10 seconds that it traveled.

I did the integration and got 383.33m traveled in 10 seconds.

So the answer is 383.33 meters.

Ignore the final answer in the image. I misread the question.

Factor completely y^2-xy-56x^2
olga2289 [7]
You can factor this out by thinking of the factors of 56 that have a sum of -1. 7 and 8 are factors of 56 and to get a sum of -1, 8 should be negative. 7 + -8 = -1

So y^{2} - xy -  56x^{2} factored out is (y+7x)(y-8x)

We can check this using FOIL
F = (y)(y) = y^{2}
O = (y)(-8x) = -8xy
I = (7x)(y) = 7xy 
L = (7x)(-8x) = -56x^{2}
y^{2} - 8xy + 7xy - 56x^{2} Combine like terms
y^{2} - xy - 56x^{2}

Solve for x in the following figure. Choose the appropriate result.
pickupchik [31]

Answer:

d

Step-by-step explanation:

all of the angles add up to equal 180 so we setup the equation as 45+3x=180

first you subtract each side by 45

135=3x

then you divide each side by 3 and get that

x=45
