C^2-64 is a square roots factoring one. you take the square root of c^2 which is c and then the square root of 64 which is 8 or -8 so the answer is (c-8)(c+8). and it is a special product

Answer:
The desired distance is 15 units.
Step-by-step explanation:
Note how x increases from 1 to 10 and y from 0 to 12 at the same time.
Using the Pythagorean Theorem, we find that the distance between the two points is the length of the hypotenuse, which is
d = √[ (10 - 1)^2 + (12 - 0)^2 ], or d = √ [81 + 144] = 225 = +15
The desired distance is 15 units.
Answer:
The volume of the cone is 42.6 m^3
Step-by-step explanation:
The volume of a cone is given by the area of the base multiplied by the height of the cone and divided by three. The base is a circle, so it's area is computed by the following:
Abase = pi(r^2) = 3.14(2.2^2) = 15.2 m^2
We can then compute the volume of the cone that is:
Vcone = Abase*h/3 = 15.2*8.4/3 = 42.56 m^3
The volume of the cone is 42.6 m^3
Answer:
Option B. The area will increase by a factor of 4
Step-by-step explanation:
we know that
The area of triangle is equal to
where
b is the base of triangle
h is the height of triangle
If the height of the triangle is increased by the factor of 4
then
The new area of the triangle will be
![Anew=4[\frac{1}{2}bh]](https://tex.z-dn.net/?f=Anew%3D4%5B%5Cfrac%7B1%7D%7B2%7Dbh%5D)
![Anew=4[A]](https://tex.z-dn.net/?f=Anew%3D4%5BA%5D)
The new area is 4 times the original area
therefore
The area will increase by a factor of 4
