Identify the horizontal asymptote of f(x) = 3 over 5 x. y = 3 over 5 y = 0 y = 5 over 3 no horizontal asymptote

Answers

y = 0 is the horizontal asymptote for the given equation f(x)

To find : Horizontal Asymptote of function f(x)

Horizontal  Asymptote

A horizontal line that a function's graph appears to coincide with but does not actually do so is said to be its horizontal asymptote. The end behavior of the function is determined using the horizontal asymptote.

Given that,

A function is provided as

f(x) = 3/5x

x serving as the denominator

By setting the denominator equal to 0, we can easily determine the vertical asymptote i.e,

Make x=0,

Specifically, the vertical asymptote is at y=0 or x=0

Identifying the horizontal asymptote

Write x in terms of y, then look for any instances where y differs.

We are able to write the given function

x=3/5

Here, y=0 renders x undefinable.

Thus y=0 is the horizontal asymptote.

Answers

The reason for 1/2 and not 5/10 is it is a norm in math to  reduce fractions to the least terms

What  is equivalent form of fractions?

This is a term used to refer to fractions that are equal even though they have different values in both he numerator and the denominator

Fractions are class of numbers that are of two parts the upper part is the numerator while the lower part is called the denominator.

In the given problem, 1/2

1 is the numerator2 is the denominator

5/10 is an equivalent form of 1/2, this means that they are equal.

5/10 is shown to be equal to 1/2 by dividing by 5, this reduces the fraction to the least term which is 1/2. Using calculator can still show it that both numbers equal 0.5

please help with part (b) of this question!! thank you!!!​

Answers

Answer:

p = 0, q = - 0.5

-------------------------------

Part (b)

Simplify first:

2p = q√76 + √192p = q(√4×√19) + √192p = 2q√19 + √192p = √19(2q + 1)

We need both p and q be rational numbers and we know √19 is irrational.

It is only possible if both side are equal to zero:

2p = 0 ⇒ p = 0,2q + 1 = 0 ⇒ 2q = - 1  ⇒ q = - 0.5

Answer:

[tex]\textsf{(a)} \quad h=3, \quad k=-2[/tex]

[tex]\textsf{(b)} \quad p=0, \quad q=-\dfrac{1}{2}[/tex]

Step-by-step explanation:

Part (a)

Rearrange the given equation so that both sides are in the same form:

[tex]\begin{aligned}2-h\sqrt{11}&=-3\sqrt{11}-k\\2-h\sqrt{11}+k&=-3\sqrt{11}-k+k\\k+2-h\sqrt{11}&=-3\sqrt{11}\\k+2-h\sqrt{11}-2&=-3\sqrt{11}-2\\k-h\sqrt{11}&=-2-3\sqrt{11}\\\\\implies h&=3\\\implies k&=-2\end{aligned}[/tex]

Part (b)

Rewrite and factor the right side of the equation.

As p and q are rationals, both sides of the equation have to equal zero.

[tex]\begin{aligned}2p&=q\sqrt{76}+\sqrt{19}\\2p&=q\sqrt{4 \cdot 19}+\sqrt{19}\\2p&=q\sqrt{4} \sqrt{19}+\sqrt{19}\\2p&=2q\sqrt{19}+\sqrt{19}\\2p&=\sqrt{19}(2q+1)\\\\\implies 2p&=0 \implies p=0\\\implies 2q+1&=0 \implies q=-\dfrac{1}{2}\end{aligned}[/tex]

Answers

The correct statement is 'Sally rode 39 miles in 3 hours. To compute Sally's unit rate, divide both the numerator and denominator by 3'

In this question, we have been given a statement 'Sally rode 39 miles in 3 hours. To compute Sally's unit rate, divide both the numerator and denominator by ____'

We need to complete given statement.

We know that, the denominator in unit rate is always 1.

So, to find unit rate we need to divide the denominator with the numerator in such way that the denominator becomes 1.

Sally's unit rate is 39/3 miles per hour

numerator = 39 and denominator = 3

We need to make denominator 1 so divide numerator as well as denominator by 3.

So, the unit rate would be, 13/1 = 13 miles per hour

Therefore, the correct statement is 'Sally rode 39 miles in 3 hours. To compute Sally's unit rate, divide both the numerator and denominator by 3'

Answers

Answer:

The question is possibly mistyped.  The response below explains why, but also answers the questions based on a imagined relationship, instead of the one given.

Step-by-step explanation:

The equation 30 + 1.25x = 15 + 25X cannot be interpreted in the manner the questions are written.  It is really only an expression, since there is no y in the equation, only x.  We can, however, solve for x:

30+1.25x = 15 + 25x

30 - 15 = 25x - 1.25x

15 = 13.75x

x = (15/13.75)

x = 1.0909

There is no other information to discern what x represents.  It could be light years to a particular comet, grams of a reagent, hours until the meat is cooked, or anything the imagination allows.

If, however, the equation were something like:

  y = 1.25x + 15

we could answer the questions, as follows;

A pet sitter charges a flat fee of $15

sitter charges a flat fee of $15 plus $1.25/hr

The rest of the questions are not coherent.

A paired t-test is used to find the difference between two variables usually separated by time for the same subject. By using the paired t-test  we can find the mean difference between pairs of measurements is zero or not. So  paired t-test is used, when data is in the form of matched pairs

This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.

According to the distributive property, you can multiply a component by each addend separately before adding the total when multiplying it by two addends.

Based on this property, in order to solve a problem of this type, you have to expand the multiplication.

Answers

The cost of 15 cans will be AED 48.

According to the question,

We have the following information:

Cost of 10 cans = AED 32

Now, in order to find the cost of 15 cans, first we will find the cost of 1 can by dividing the total cost of 10 cans by the number of cans.

So, we have the following expression:

Cost of 1 can = 32/10

Cost of 1 can = AED 3.2

Now, we will find the cost of 15 cans using multiplication:

Cost of 15 cans = 15*3.2

Cost of 15 cans = AED 48
