The answer is (-21, 13) for The second endpoint.
Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 1)/2 = -10
Kx + 1 = -20
Kx = -21
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + 7)/2 = 10
Ky + 7 = 20
Ky = 13
This gives us the final point of (-21, 13)
Answer:
0.267
Step-by-step explanation:
Split it up which ever way that you want to, find the area for both the shapes you made when split. then if you write A and B for each shape it will help. after you find the area of both add them together to get the answer.
X^2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
x = -2, 4 Answer
x^2 - 5x + 14
(x - 7)(x + 2) + 0
x = -2, 7 Answer
Answer:
A≈1206.37 cm²
Step-by-step explanation:
Radius = 12
Height = 16
Using the formulas
A= πrl+πr²
l = √r²+h²
A=πr(r + √h²+r²)=
π·12·(12+√16²+12²) ≈1206.37158cm²
