Multiply the following ?

Mathematics
1 answer:
Harlamova29_29 [7]3 years ago
4 0

Answer:

\frac{3x^2}{x^2-6x-7}

Step-by-step explanation:

The first step is to find the multiplied out numerator and denominator, and then to simplify if possible. For the numerator, 3x*x=3x^2. For the denominator, (x+1)(x-7)=x^2-6x-7. This gives a final fraction of \frac{3x^2}{x^2-6x-7}. Hope this helps!

What are the domain and range of the function f(x) = 3x 5?.
Bingel [31]

The domain and range of the given function both are the real numbers.

<h2>Given that:</h2>
  • The domain and range of function f(x) = 3x + 5 has to be found.

<h2>Explanation for domain and range:</h2>

Considering working in real numbers, domain is \mathbb{R} and range is \mathbb{R} too.

Domain can be complex numbers too, but for the sake of daily life cases, we consider working in real numbers.

Thinking of it as equation of straight line can help.

The given function is monotonically increasing and continuous.

Thus Range can be calculated as  interval ( f(min value of domain), f(max value of domain) ) which gives us \mathbb{R} as range.

Below is the plot of f(x) = 3x + 5 in real number plane.

In fact, any linear equation of the form

y = mx + c ;    \: \: c \in R \: and \: m \in {R-\{0\}}

has  both domain and range as real numbers.

Ariel was told the x intercept and the y intercept of a line with a positive slope. Yet, it was impossible for Ariel to find the
alexdok [17]

A line has the following standard equation form:

y = m x + b

where m is the slope and b is the y intercept

 

So if Ariel cannot find the slope, then this would only mean that m = 0, there is no slope. And hence the line is either a straight vertical line or straight horizontal line.

 

Answer:

<span>There is no slope</span>

(d) Let p represent the probability of a successful long hit. What values of p will make the long hit better than the short hit
seropon [69]

Answer:

The probability of successful  long hit is greater than 0.7083

Step-by-step explanation:

Solution

The expected value for long hit is given below

P (successful hit) * 4.2 + P (Unsuccessful hit) *5.4

so,

= P * 4.2 + (1-p) * 5.4

= 5.4 - 1.2p

Now,

If the expected value of long hit is less than  that of the short it

Then,

5.4 - 1.2p <4.55

P> (5.4 - 4.55)/1.2

P> 0.7083

Therefore the probability of successful  long hit is greater than 0.7083

Note:

Due to my research and findings to this example, the complete question for  is attached below, i solved or Question 2(d) only
