Answer:
Each face of an octahedron is an equilateral triangle.
An octahedron is a three-dimensional solid (polyhedron) that has eight faces.
I hope this helped ! <3
Answer:
Both equations, when we replace the solution, generate identities.
Step-by-step explanation:
We are given the following system:
y = x - 7
y = -4x + 3
We are given the following solution.
(2,-5).
First equation:
We have to show that when x = 2, y = -5. So
y = x - 7
-5 = 2 - 7
-5 = -5
So ok
Second equation
We have to show that when x = 2, y = -5. So
y = -4x + 3
-5 = -4(2) + 3
-5 = -8 + 3
-5 = -5
We generate both identities, so the solution is checked.
I is an imaginary number used to find the square root of a negative number.
sqrt-1 is 1i
sqrt-16 is 4i and so on
Alright, buckle in because this will be a bit of a bore to listen to.
First, find the areas of all surfaces that you have the length and width of, which i assume you already have.
Next, use the Pythagorean theorem to find the missing measure of that triangle to find the measure of it and the back. make sure to find ALL of the sides, including the ones on the backside of the figure. Too lazy to do it myself, but at least you know how i'd do it.
To compare the speed for the both of them, it would be helpful to convert the units to the same units in this case to units of meters per minute. We calculate as follows:
27 / 60 minutes = 0.45 km/minute
0.45 × 1000 = 450 m/minute
14 x 60 = 840 dm/minute
840 / 10 = 84 m/minute
450 - 84 =<span> 366 m/minute faster than the girl</span>
