Answer:using the graph of a function you can find the value of f (x), all you need to do is locate on the x axis, the value, in this case 3, and we will find f (3), locate the number (3 ) on the x-axis and see what is the value of y that the function takes at that point, that will be the value f (3)

Step-by-step explanation:it’s a

b. The function f(x)=g(x)/h(x) will have a horizontal asymptote only if the degree of g is less than or equal to the degree of h.

Using n for the variable, write an algebraic expression that represents a number that is divisible by the given number. (Hint: A

PtichkaEL [24]

Answer:

$a) 5n\\b) 10n\\c) 3n$

Step-by-step explanation:

Let 'n' be any integer i.e. a number from the set {....., -3,-2,-1,0,1,2,3, ..... }

so 'n' can be termed as the variable here.

A number 'q' that can be divided by a a given number 'p' can be written as:

$n \times p$

When divided by 'p' :

$\dfrac{q}{p} = \dfrac{n \times p}{p}\\\Rightarrow \dfrac{q}{p} = n$

So, The number 'q' is completely divisible by 'p' leaving 'n' as the quotient.

Using this concept, let us solve the questions:

a) Using 'n' as the variable, a number that is divisible by 5 can be written as:

$5n$

b) Using 'n' as the variable, a number that is divisible by 10 can be written as:

$10n$

c) Using 'n' as the variable, a number that is divisible by 3 can be written as:

$3n$

I think it’s B. But I’m not sure <br><br> If it’s not can someone explain why?

Zigmanuir [339]

Answer:

Step-by-step explanation:

| x | > 10

Has solutions that go infinitely high to the right and infinitely low to the left on the number line.

That is x > 10 or x < - 10

This is indicated on Graph C

A bag contains 7 red, 4 blue, and 6 white marbles.

Leno4ka [110]

Answer:

28/289

Step-by-step explanation:

7 red, 4 blue, and 6 white = 17 marbles

P ( red ) = number of red / total

= 7/17

Replace the marble

7 red, 4 blue, and 6 white = 17 marbles

P ( blue ) = number of blue / total

= 4/17

P (red, replace, blue) = 7/17* 4/17

=28/289

I need help with a calculus 2 exercise, with a good explanation to what I'm trying to figure out.

Karolina [17]

<h3>Explanation:</h3>

When writing rational expressions, you need to be aware that ...

1/4x = (1/4)x ≠ 1/(4x)

Parentheses around the denominator are required, unless you're typesetting the expression and can use a fraction bar for grouping.

The derivative of the curve expression is ...

y' = x - 1/(4x) . . . . . parentheses added to what you wrote

and the expression (1 -(y')^2) can be written ...

1 -(y')^2 = x^2 +1/2 +1/(16x^2) . . . . . parentheses added to what you wrote

The first and last terms of this trinomial are both perfect squares, so you might suspect the whole trinomial is a perfect square. You recall that ...

(a +b)^2 = a^2 + 2ab + b^2

This is a good "pattern" to remember. Using it is a matter of <em>pattern recognition</em>, as is the case with a lot of math.

Here, you have ...

a = x

b = 1/(4x)

In order for your trinomial to be a perfect square, the product 2ab must equal the middle term of your trinomial. (Spoiler: it does.)

2ab = 2(x)(1/(4x)) = (2x)/(4x) = 1/2 . . . . . matches the middle term of 1 -(y')^2

Hence your trinomial can be written as the square ...

1 -(y')^2 = (x +1/(4x))^2

_____

This is convenient because you want to integrate the square root of this. Your integral then becomes ...

$\displaystyle\int\limits_{2}^{4}{\left(x+\frac{1}{4x}\right)\,dx$
