4. Divide z(5z2 - 80) by 5z (z+4)​

Mathematics
1 answer:

Answer:

z-4

Step-by-step explanation:

z(5z²-80) ÷ 5z(z+4) = z-4

Step-by-step explanation:

Given: z(5z²-80) ÷ 5z(z+4)

Calculation:

First we factor numerator z(5z²-80)

Take out 5 from 5z²-80 and we get 5z(z²-16)

Now we factor 16 = 4²

5z(z²-4²)

Using formula, (a²- b²)=(a+b)(a-b)

5z(z²- 4²)⇒5z(z+4)(z-4)

Simplified fraction

5z(z+4)(z-4) ÷ 5z(z+4)

Cancel like factor from numerator and denominator

⇒ z-4

Thus, z(5z²-80) ÷ 5z(z+4) = z-4

Analyze the asymptotes of the function.
koban [17]

Answer:

vertical asymptote at x=-1

horizontal asymptote at y=0

Step-by-step explanation:

y=\frac{1}{x+1}

To find vertical asymptote we set the denominator =0 and solve for x

x+1=0 (subtract 1 from both sides)

x=-1

So, vertical asymptote at x=-1

To find horizontal asymptote we look at  the degree of both numerator and denominator

there is no variable at the numerator , so degree of numerator =0

degree of denominator =1

When the degree of numerator is less than the degree of denominator

then horizontal asymptote at y=0

A. what is asked?
Andru [333]

Answer:

A. How much Anna weights in kilograms is what is asked (Btw is it her or his?)

B. The values given is 54000 (most likely in grams )

C. The operation that is going to be used is 1000 since kilograms is 1000 grams

D. The solution is 54 kilograms

E. To get 54 kilograms to grams we can just multiply by 1000 again which will result into 54000 thus the answer is correct

Step-by-step explanation:

A:

The question is asked when there is a "what" or a problem statement

B:

The only value or digits given is 54000

C:

in the Metric Scale Kilograms is 1000 times larger in value than grams thus 1000

D:

Divide 54000 with 1000 which is 54

E:

Um.... just multiply 1000 ._. (That's the only way I can check it)

Hope this helps!
