Answer:

2. The y-intercept is 33 ft. The ball is 33 feet away from the wall.  

3. It will take the ball 11 seconds to touch the wall.  

4. The slope is -3 ft. The ball is rolling toward the wall at 3 ft per second

Step-by-step explanation:

Let x be the number of seconds.

We are told that a ball is rolling at a rate of 3 ft per second toward a wall that is 33 feet away.  

Since the ball is rolling towards wall at a rate of 3 ft per second. This means that remaining distance between wall and ball is decreasing 3 ft with each passing second. Hence, the slope of our line will be negative 3 ft.

As initially ball was 33 feet away from wall, so our y-intercept will be 33.

Upon substituting our values in slope-intercept form of equation we will get equation of our line representing remaining distance between ball and wall after x seconds as:  

y=-3x+33

Let us find the number of seconds that ball will take to touch the wall by finding the x-intercept of our line. Since x-intercept is the point when line crosses x-axis and at this point y equals 0. The x-Intercept of a line is obtained by putting the value of y as zero in the equation of a line.

0=-3x+33

0-33=-3x+33-33

-33=-3x

\frac{-33}{-3}=\frac{-3x}{-3}

11=x

Therefore, after 11 seconds ball will touch the wall.

Upon looking at our choices we can see that 2nd, 3rd and 4th options are correct choices.

A polynomial is to be constructed that will touch the x axis at most 8 times. What is the minimum degree of the polynomial?
Harman [31]
The maximum number of roots to a polynomial of order n is n roots. Take the example of a quadratic (order 2) which can intersect the x-axis a maximum of 2 times, and similarly a cubic (order 3) 3 times maximum.

Hence for 8 intersections, minimum order = 8

Pls helpppppp thanks!!!!!!!<br> :)
Lena [83]

Answer:

If i did this right the answer would be 69

I converted the inches to feet (might be my first mistake)

so i get 2.5 X 1 X 1 to get 2.5

i then multiply that by 62.4 to get 156

then 225-156 = 69
