Answer:

9n^4

Step-by-step explanation:

The divisor and quotient can be interchanged to find the divisor:

$\dfrac{18n^6+27n^5-36n^4}{2n^2+3n-4}=\boxed{\text{Blank 1}}$

Such division is carried out by first finding the quotient of the highest-degree terms:

$\dfrac{18n^6}{2n^2}=\dfrac{18}{2}n^{6-2}=9n^4$

This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...

9n^4

_____

The attachment shows the long division.

Which of the following observations of children is the most objective?

Ivan

I'd say D. A uses words that suggest the author has an opinion of Alex's behavior that is unfavorable. B uses the words "obviously less disciplined" to refer to Sue, which is clearly an opinion and also rather unfavorable. C makes assumptions as to Joan's emotions toward Mary, which cannot be ascertained objectively without asking Joan. D is a clear statement of the facts without embellishment.

EDIT: Note that the definition of objective is not influenced by opinions or beliefs, as opposed to subjective.

The diameter of a sphere is 16 in. What is the sphere's volume? Round to the nearest tenth, if necessary. A) 971.7 in3 B) 1072.3

statuscvo [17]

Volume of sphere = 4/3πr³

r is radius.

Radius = diameter/2 = 16/2 = 8

Volume = 4/3(3.14)(8)³
Volume = 2143.57

Rounded to nearest tenth would be 2144.7 in³

The answer is D.

Hope this helps :)
