Answer:

The negative x-intercept is at (-1/3 , 0).

The positive x-intercept is at (4 , 0).

Explanation:

Where does f(x) = 3x2 – 11x – 4 intersect the x-axis?

The negative x-intercept is at (-1/3 , 0).

The positive x-intercept is at (4 , 0).

Set f(x) equal to zero so

3x2 – 11x – 4 = 0

Plug in a. b, and c into the quadratic formula

and get 2 solutions:

1/3 and -4

take the opposite signs and put it in the x intercepts

Answer:

3)  y = 2

Step-by-step explanation:

Step : 1

given 2 y-1 =3

Adding '1 ' on both sides, we get

2 y -1 +1 = 3+1

2 y = 4

dividing by '2' on both sides, we get

\frac{2y}{2} = \frac{4}{2}

cancelling '2' on both sides, we get

y = 2

A circle has a diameter of 29 feet. What is the area? *
11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

radius =  \frac{diameter}{2}  \\ radius  =  \frac{29}{2}  \\  = 14.5 \:  \: feet

So the area of the circle is

A =  {14.5}^{2} \pi \\  = 210.25\pi \\  = 660.519...

We have the final answer as

<h3>660.5 square feet</h3>

Hope this helps you
