Factorise using identities p^2 +8p+16

p2 - 8p + 16 = (p)2 - 2(4)(p) + (4)2 = (p - 4)2 [Using a2 + b2 - 2ab = (a -b)2] = (p - 4) (p - 4) Thus, p2 - 8p + 16 = (p - 4)(p - 4)

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
