Let be A= 6x6 − x3y4 − 5xy5 and B= 4x5y + 2x3y4 + 5xy5 and when we do their difference, it is A - B = 6x6 − x3y4 − 5xy5 -( 4x5y + 2x3y4 + 5xy5)=6x6 − x3y4 − 5xy5 - 4x5y - 2x3y4 - 5xy5 = 6x6 - x3y4 - 2x3y4 - 5xy5 -4xy5 -5xy5=6x6 - 3x3y4 -14xy5, so the final solution is A - B =6x6 - 3x3y4 -14xy5, the degree of this is equal to the degree of - 3x3y4, and it is 3+4=7, the answer is The difference has 3 terms and a degree of 7.

Actually the correct answer is The difference has 4 terms and a degree of 7.Ii just taken a pre test over this.

Write an equation of the line that passes through (-3,3) and is perpendicular to the line 2y=8x-6

jok3333 [9.3K]

Answer:

y = (-1/4)x + 9/4

Step-by-step explanation:

2y = 8x - 6

So, y = 4x - 3 (Slope = 4)

Slope of perpendicular line = -1/4

Equation of line: y-3 = (-1/4)(x-(-3))

y-3 = (-1/4)x - 3/4

y = (-1/4)x + 9/4

Which decimal number is equal to 3/18 A.0.167 B.0.16 C.0.16 D.0.167

natita [175]

Answer:

0.167

Step-by-step explanation:

Note that 3/18 reduces to 1/6. 1/6 is a rational number whose decimal equivalent is repeating: 1/6 = 0.166666 ...

It appears that answer choices A and D are identical, as arer B and C. You might want to verify that you've copied down the answer correctly.

Answers A and D (identical) are the best choices here, due to less rounding off.

Calculus Help!

Answer:

Yes.

Step-by-step explanation:

You would have to use L'Hopital's Rule. Infinity/Infinity is undefined, just like 0/0 is undefined.

I just googled this.

Before trying other techniques, plug in the arrow number. If the result is:

A number, you’re done.

A number over zero or infinity over zero, the answer is infinity.

A number over infinity, the answer is zero.

0/0 or ∞/∞, use L’Hôpital’s Rule.

The thing is, when you say you got your limit, do you mean $\lim_{n \to \infty} (n+1)/n$ ?

This can just be found out by dividing by highest denominator power on numerator and denominator..

$\lim_{n \to \infty} 1 + 1/n$

the limit of 1 is 1.

the limit of 1/x is 0.

because its equal to one it diverges.
