Answer:

(370-2x)ml

Step-by-step explanation:

We are given that

In first hand sanitizer

Total solution=200ml

Alcohol=15% of 200ml

Alcohol=\frac{15}{100}\times 200=30ml

In second hand sanitizer

Solution=200 ml

Alcohol=x% of 200 ml

Alcohol=\frac{x}{100}\times 200=2x ml

We have to find the water in the resulting mixture of hand sanitizers.

Total solution of two hand sanitizers=200+200=400ml

Total alcohol in two hand sanitizers=(30+2x)ml

Water in two hand sanitizers=400-(30+2x) ml

Water in two hand sanitizers=400-30-2x ml

Water in two hand sanitizers=(370-2x)ml

Hence, water  in the resulting mixture of hand sanitizers=(370-2x)ml

mario62 [17]

The leading term of polynomial function is the the term contain highest degree so here in the given question leading term is  -3x^5

and leading coefficient is the coefficient of the term with greatest exponent -3

RULES for End behaviour

we have following four cases

CASE1: Even degree and positive leading coefficient

x\rightarrow -\infty      f(x)\rightarrow \infty

x\rightarrow \infty        f(x)\rightarrow \infty

CASE2: Even degree and negative leading coefficient

x\rightarrow -\infty        f(x)\rightarrow -\infty

x\rightarrow \infty           f(x)\rightarrow -\infty

CASE3: Odd degree and positive leading coefficient

x\rightarrow -\infty          f(x)\rightarrow -\infty

x\rightarrow \infty              f(x)\rightarrow \infty

CASE4: Odd degree and negative leading coefficient

x\rightarrow -\infty              x\rightarrow \infty  

x\rightarrow \infty                  f(x)\rightarrow -\infty


Here in the given case we have odd degree and negative leading coefficient

x\rightarrow -\infty              x\rightarrow -\infty  

x\rightarrow \infty                  f(x)\rightarrow -\infty
