Answer:
The degree is 7 and the leading coefficient is -21.
Step-by-step explanation:
The degree of an equation is found using the highest exponent on the variable in the equation.
-12-8x^2+5x-21x^7 has the term x^7 so its degree is 7
The leading coefficient is the coefficient of the term with the highest degree. The coefficient of x^7 is -21.

Answer:
20π or 62.8
Step-by-step explanation:
Volume of a cone = 1/3πr²h
1/3(π)(2)²9
= 12π or 37.7
Volume of a hemisphere = 2πr²/3
2(π)(2)²
= 8π or 25.1
Total Volume = 20π or 62.8
Answer:

Step-by-step explanation:
Given
Represent point A as thus;

Required
Determine the new position of A, when rotated counterclockwise
The new position will be denoted as A'
When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:

Then, y is negated to give A'

Answer: 4x^3 + x + 1
Step-by-step explanation: Combine like terms.
