Answer:

Step-by-step explanation:
Apply pythagorean theorem:
ABD is a right triangle with angle ADB = 90
hence AD =
where BD = 10 because it is half of BC
AD =
= 
Answer:
II (THE Second one )
Step-by-step explanation:
Because when you substitute X by (-2)
you will get :
y=(-2)^2 - 6(-2) - 16 = Zero
So, -2 is not including in the interval .
Answer:
- Mass
- Surface area
- Volume
Step-by-step explanation:
The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle, or surface of a solid (3-dimensional) object
<u>Mass </u>
A property of a physical body and a measure of its resistance to acceleration when a net force is applied.
<u>Surface </u>
The area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
<u>Volume </u>
The Measure of the amount of space that a substance or an object takes up.
<span>If you are adding a constant, then the graph is either raised or lowered k units.
For example.... If you have the graph of y = x^2
and now you add 3, so your new graph of x^2 + 3, will be the same graph as x^2 but raised vertically 3 units.
The graph of x^2 - 7 will be the graph of x^2 lowered vertically 7 units.
