Find the distance between (-1,4) and (1,-1)
Alex Ar [27]

Answer:

d=\sqrt{29}

Step-by-step explanation:

The trick here is knowing the distance formula:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

using that equation with (-1,4) and (1,-1), we get:

d=\sqrt{(1-(-1))^2+((-1)-4)^2}\\d=\sqrt{(1+1)^2+(-1-4)^2}\\d=\sqrt{(2)^2+(-5)^2}\\d=\sqrt{4+25}\\d=\sqrt{29}\\

<span>Given that f(x) = 2x + 5 and g(x) = x − 7

</span>f(g(x)) = 2(x − 7) + 5
f(g(x)) = 2x - 14 + 5
f(g(x)) = 2x - 9

when x = −3 , f(g(-3)) = 2(-3)  - 9 = - 6 - 9 = -15

A fluorite crystal is shaped like a regular octahedron with edges that are 2.1 inches. Which of these is the volume of the fluor
Anni [7]
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above: The<span> regular octahedron with edges that are 2.1 inches.

 2. Therefore, you must apply the formula for calculate the volume of a octahedron, which is:

 V=(a^3</span>√2)/3

 3. Therefore, you have:

 V=((2.1 inches)^3√2)/3
 V=178.30 inches^3
