QUESTION 1

i) The given function is

f(x)=\frac{3(x-1)(x+1)}{(x-3)(x+3)}

The domain is

(x-3)(x+3)\ne0

(x-3)\ne0,(x+3)\ne0

x\ne3,x\ne-3

ii) To find the vertical asymptote equate the denminator to zero.

(x-3)(x+3)\=0

(x-3)=0,(x+3)=0

x=3,x=-3

iii) To find the roots equate the numerator zero.

3(x-1)(x+1)=0

3(x-1)=0,(x+1)=0

(x-1)=0, (x+1)=0

x=1, x=-1

iv) To find the y-intercept substitute x=0 into the function;

f(0)=\frac{3(0-1)(0+1)}{(0-3)(0+3)}

f(0)=\frac{-3}{(-3)(3)}

f(0)=\frac{1}{3}

The y-intercept is \frac{1}{3}

v) The horizontal asymptote is given by

lim_{x\to \infty}\frac{3(x-1)(x+1)}{(x-3)(x+3)}=3

The horizontal asymptote is y=3

vi) The rational function has no common linear factor.

This rational function has no holes.

vii) This rational function is a proper function. It has no oblique asymptote.

When a ferry boat is on open water, it travels at a constant speed. A ferry boat traveled 4 miles in 10 minutes. Complete the eq
ozzi

Answer:

The equation is: y=0.4x

The relationship between  the time in minutes, t, and the distance traveled in miles, d is a straight line, as shown in attached graph.

Step-by-step explanation:

As boat travels at constant speed.

So, if ferry boat travels 4 miles in 10 minutes. It means it would complete 24 miles in one hour.

And in 1 minute, 0.4 miles will be completed.

So, the equation becomes

y=0.4x

As the slope intercept form is y=mx+c

So, m=0.4 is the slope

The relationship between  the time in minutes, t, and the distance traveled in miles, d is a straight line i.e. linear.

The graph is also attached which indicates that relationship between  the time in minutes, t, and the distance traveled in miles, d is a straight line i.e. linear.

Mai and Jada are both running on a treadmill. Mai travels 5 miles in 15 minutes. Jada travels 4 miles in 14 minutes. Who ran at
sasho [114]

Answer:

Mai

Step-by-step explanation:

To find the rate, you must determine who is going faster per minute. To do this, you must divide the total number of miles by the total number of minutes.

Mai: 5 miles / 15 minutes = 1/3 miles per minute

Jada: 4 miles / 14 minutes = 2/7 miles per minute

Then, use a common denominator to make calculations easier:

Mai: 1/3 * 7/7

Jada: 2/7 * 3/3

You should get:

Mai: 7/21 miles per minute

Jada: 6/21 miles per minute

By looking at this, you can see that Mai is traveling slightly faster, going more miles than Jada per minute.

What does this equal to? <br> 8ft 12 in. = ____yd
MissTica
First:
3 feet=1 yard
36 inches=1 yard

8 feet=2 \frac{2}{3} of a yard
12 inches=1/3 of a yard.

2<u />\frac{2}{3}+\frac{1}{3}=2\frac{3}{3} or 3. 

Hope this helps!
