ANSWER

$x = 1\: or \: x = - 5$

EXPLANATION

The given rational expression is

$\frac{(x - 1)(x + 5)}{x - 5}$

For the given rational function to be zero, then the numerator must be equal to zero.

We now equate the numerator to zero and solve for x.

This implies that,

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

We use the zero product property to obtain,

$(x - 1) = 0 \: or \: (x + 5) = 0$

$x = 1\: or \: x = - 5$

Hence the zeros of the given rational function are x=-5,x=1

Answer:

1 and -5

Step-by-step explanation:

0 divided by anything is 0

the numerator can equal zero if one factor =0

x-1=0

x+5=0

solving, we get x=1 or x=-5

Answer: 155y seconds

Step-by-step explanation:

Difference between 3y minutes and 25y seconds is written as

3y minutes- 25y seconds

First, Convert minutes to seconds = 60 seconds makes 1 minute, therefore, 3 minutes = 60 x 3= 180 seconds

Therefore 180y seconds - 25y seconds

= 155y seconds

Answer:

Not a function

Step-by-step explanation:

For every input there is one and only one output. So on this graph, it shows that there are two dots on a single vertical line, which means that there are two outputs. Because the definition of a function is "for every input there is one and only one output" we know that it is not a function.

Suppose the null hypothesis, H0, is: the mean age of the horses on a ranch is 6 years. What is the Type I error in this scenario

Morgarella [4.7K]

Answer:

Step-by-step explanation:

A type 1 error is committed when a true null hypothesis is rejected. Looking at the given scenario, given that the null hypothesis, H0 states is stated as follows:

The mean age of the horses on a ranch is 6 years, then a type 1 error would be made if the conclusion states that the mean age of the horses on a ranch is lesser or greater than 6 years when it is actually 6 years. Therefore, the correct option is

You cannot conclude that the mean age of the horses on a ranch is 6 years when, in fact, it is.

Classify each situation as exponential growth, exponential decay, or linear.

Harrizon [31]

Answer:

1) exponential decay

2) linear

3) exponential growth

Step-by-step explanation:

1) The first question is like, initially 600 people watched, after 3 days 480.

This means it is decay. The difference in first day and after 3 days is 120.

To be linear, further after 3 days, or from start after 6 days, the population should be 360. But it is given to be 384.

Thus exponential decay.

2) In second, Initially, 400 liters of water is there. After 2 hours, the tank has 340 litres. Thus the loss in 2 hours is (400 - 340) = 60 liters.

After 4 hours, the loss is (340 -280) = 60 liters.

As the loss is same in equal intervals of time, the decay is linear.

3) In third one, Initially there are 512 birds.

After 2 years there are 768 birds, thus the growth is (768-512) =256.

After 4 years, There are 1152 birds. Thus the growth is (1152 - 768) = 384.

Thus the increase is non linear, and so exponential growth.
