Sorry I need to answer something so I can ask questions so I’m typing this
Answer:
O(4.-1.5) should be the answer
Answer:
(3,-1)
Step-by-step explanation:
(2+4)/2. (5-7)/2
6/2. - 2/2
3,-1
To answer the question we proceed as follows:
suppose a cone has a height x units and radius x units
volume will be:
v=1/3πr²h
V=1/3πx³ cubic units
when we add 1 unit to the radius and subtract 1 unit from the height the volume will be:
v=1/3π(x+1)²(x-1)
v=1/3π(x³+x²-x-1) cubic units
comparing the above values for volume we conclude that the volume will not be the same. This means the volume won't stay the same after changes.
Answer:
f(x) = x^4 +4x^3 +5x^2 +4x +4
Step-by-step explanation:
If "a" is a zero, then (x-a) is a factor. The conjugate of a complex zero is also a zero if the polynomial has real coefficients. Then the factorization is ...
f(x) = (x -(-2))(x -(-2))(x -i)(x -(-i)) = (x^2 +4x +4)(x^2 +1)
f(x) = x^4 +4x^3 +5x^2 +4x +4
