Answer:

Chemical Engineering

Explanation:

Testing in chemical Engineering is one of the ways of knowing how effective a chemical solution or solvent made or a chemical production is. testing also in chemical Engineering is used to inform the chemical engineer on the damages or dangers that make occur if a particular chemical composition is found in a finished product. therefore testing in Chemical Engineering is mainly for informative purpose.

Marine Engineering and other forms of Engineering doesn't require testing on finished products but on raw materials to be used because testing of finished products in these types of Engineering might lead to fatalities hence testing s carried out on raw materials which is ideally not part of the Engineering before used in creating products.

simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9

Answer:

The simplified expression is: $\frac{2m-5}{m-3}$

The simplified expression is undefined for m=3

Explanation:

The given expression is:

$\frac{2m^2+m-15}{m^2-9}$

The numerator can be siplified by using factorization and denominator will be simplified using the formula

$a^2-b^2 = (a+b)(a-b)$

So,

$= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}$

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.

So,

$m-3 = 0 => m = 3$
