Answer: 2520

----------------------------------------------

Work Shown:

P(n,r) = (n!)/((n-r)!)
P(7,5) = (7!)/((7-5)!)
P(7,5) = (7!)/(2!)
P(7,5) = (7*6*5*4*3*2*1)/(2*1)
P(7,5) = (5040)/(2)
P(7,5) = 2520

~~~~~~~~~~~~~~~~~~~~~~~~~~

Product Property: <span>Sometimes also referred to as the <em>Zero Product Property</em>, states that if AB=0 , than A=0 and/or B=0.</span>

Example: If AB=0, than A=0 and/or B=0.


Quotient Property: <span>Sometimes also referred to as the Quotient <em>of Powers Property</em>, states that when you have the same base, you subtract the exponents.</span>

Example: (5^3)/(5^7) = 5^-4 OR 1/(5^4)


Negative Exponent: <span>This simply means "<em>How many times I you divide by that number?</em>"</span>

Example: 5^-3 = 5/5/5 = 0.2


Power of a Power Property: <span>Sometimes also referred to as the <em>Product of Powers Property</em>, states that rather than adding the exponents of that base, you multiply them instead.  This is the way to find the single exponent of the base.</span>

Example: 5^3^3 = 5^(3*3*3) = 5^27


Power of a Product Property: For this property, rather than multiplying the exponents of the same base, you add them instead.

Example: 5^3 * 5^15 = 25^18

3) Find the area of JUST the wood portion of the frame. This is called a composite figure.
dlinn [17]

The length of given frame is 7 inches

The width of given frame is 5 inches

Assume the thickness of frame is 1 inches (as it is not clear in picture)

Area of square will be 7*5= 35 sq.inch.

Area of hollow surface 5*3= 15 sq.inch.

Area of frame = square area- hollow area= 35-15

Area of wooden portion of frame = 20 sq.inch.

Find the surface area of a square pyramid with each side of the base measuring 6 cm and the slant height is 12 cm. What are the
Debora [2.8K]
The square base area is 6 x 6 = 36. Then each triangle is the same base and height. Formula for area is 1/2(b)(h). So, each triangle is 1/2(6)(12)=36. So all sides are 36x5=180 units squared.
