Determine the intervals on which the polynomial is entirely negative and those on which it is entirely positive. (Enter your ans
Stells [14]
This is a parabola that opens downward.
Remember that the axis of symmetry is located at x=-b/(2a).
So the vertex is at (3,-1)
So functions slope is positive or increasing on (-co, 3] and decreasing on [3,co).

If a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line x = 1, what will be the r
Alik [6]

Answer:

The resulting three-dimensional object will be a cone

Step-by-step explanation:  

Plot the figure to better understand the problem'

we have

a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1)

The draw in the attached figure

we know that

When rotating a a right triangle about a leg, the three dimensional figure formed is a cone

The radius of the cone will be equal to the base of right triangle and the height of the cone will be equal to the height of the triangle

so

The radius of the cone will be equal to 2 units and the height of the cone will be 3 units

see the attached figure to better understand the problem

What is the least positive integer divisible by the numbers 2, 4, and 7?
Viefleur [7K]

Answer:

Least positive integer divisible by the numbers 2, 4, and 7 is  28

Step-by-step explanation:

We can find the least positive integer divisible by the numbers 2, 4, and 7 by taking the LCM

First lets List all prime factors for each number.

Prime Factorization of 2

2 is prime  =>  2^1

Prime Factorization of 4 is:

2 x 2  =>  2^2

Prime Factorization of 7 is:

7 is prime  => 7^1

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 7

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 7 = 28
