5 0

Answer:

see explanation

Step-by-step explanation:

The diagrams show triangular figures

The first figure has 1 dot

The second has 1 + 2 = 3 dots

The third has 3 + 3 = 6 dots

The fourth has 6 + 4 = 10 dots

Note the pattern is + 2 , + 3, + 4

Thus the fifth pattern is 10 + 5 = 15 dots

The length of a rectangle is represented by x, the width is represented by 6x^2-4x-2. What is the area of the rectangle?
navik [9.2K]

Answer:

2x(3x^2-2x-1)

Step-by-step explanation:

Area of a rectangle is simply length times width

{6x^2-4x-2} * x    would be the area

That can be simplified to

6x^3-4x^2-2x

Which can be further simplified to

2x(3x^2-2x-1)

Use the function f(x) = 2x2 − 3x − 5 to answer the questions.
Dovator [93]

Answer:

see below

Step-by-step explanation:

A:  2x² - 3x - 5

    (2x - 5)(x + 1)

B:  Set the factored equation equal to zero and solve for x.

(2x - 5)(x + 1) = 0

2x - 5 = 0

2x = 5

x = 5/2

x + 1 = 0

x = -1

The x-intercepts are 5/2 and -1

C)  To find the end behavior, you need to look at the term in the unfactored equation with the highest exponential number.  For this equation, that is 2x².  Since the exponent is positive,  both ends of the graph will point in the same direction.  Because the leading coefficent is positive, the graph will point upwards.  The end behavior of the graph is that as the x-values approach both ∞ and -∞, the function approaches ∞.

D)  Since we know that the x-intercepts are 5/2 and -1, you can plot these points.  You also know that the graph will be in an upward U shape.  Plug in  a couple x-values and plot them to make the graphing of the equation more accurate.
