Solve the equation 25x^2+121=0

Answers

Answer 1

Subtract 121 from both sides:

[tex]25x^2=-121[/tex]

Divide both sides by 25:

[tex]x^2 = -\dfrac{121}{25}[/tex]

The solutions would be

[tex]x = \pm\sqrt{-\dfrac{121}{25}}[/tex]

This expression cannot be evaluated using real numbers, because the square root of negative numbers are not allowed. If we're using complex numbers, the solutions are

[tex]x = \pm\sqrt{-\dfrac{121}{25}} = \pm\dfrac{11i}{5}[/tex]

7. David bought two types of cards. He bought x type of cards that cost $4 andy
type of cards that cost $2. There are a total of 22 cards and they have a total cost of
$26. If he bought 5 of the $4 type of cards, how many of the $2 cards did he buy?
cards

Answers

Answer:

Step-by-step explanation:

x +  y = 22

22 cards = 26

5(4) +y(2) = 26

20+2y = 26

20-20 +2y = 26-20

2y =6

2y/2 = 6/2

y = 3

andy bought 3 cards

David bought 5 of the $4 cards and 17 of the $2 cards. By setting up and solving the equations, we determined the number of each type of card he purchased.

To solve this problem, we set up two key equations based on the given information.

Let x be the number of $4 cards and y be the number of $2 cards.

The equations are:

Total cards: x + y = 22Total cost: 4x + 2y = 26

We know that David bought 5 of the $4 cards.

Therefore, x = 5.

Substituting x into the first equation:

5 + y = 22

y = 22 - 5

y = 17

So, David bought 17 of the $2 cards.

Decide if the following scenario involves a permutation or combination. Then find the number of possibilities. The student body of 165 students wants to elect 3 representatives

Answers

Answer:

735,130.

Step-by-step explanation:

The order of election of the 3 representatives does not matter so it is a combination.

The number of possible combinations

= 165! / 162! 3!

=  (165 * 164 * 163) / (3*2*1)

= 735,130.

Final answer:

The scenario of electing 3 representatives from a student body of 165 students involves combinations since the order of selection does not matter. Using the combination formula, there are 4,598,340 possible ways to choose the representatives.

Explanation:

The scenario described involves electing 3 representatives from a student body of 165 students. In this context, we are dealing with combinations, not permutations, because the order of selection does not matter; it only matters who is chosen, not in which order they are elected.

To calculate the number of possible combinations of 165 students taken 3 at a time, we can use the combination formula:

C(n, k) = n! / [k!(n - k)!]

where:

n = total number of items,k = number of items to choose,! indicates a factorial, which is the product of all positive integers up to that number.

Therefore, the number of possibilities is:

C(165, 3) = 165! / [3!(165 - 3)!]

Calculating this gives us:

165! / (3! * 162!) = (165 * 164 * 163) / (3 * 2 * 1) = 4,598,340 combinations.

Answers

Final answer:

We found the values of the function f(x) at points 1 and 3 and compared them. It's found that the value of f(1) is significantly larger than the value of f(3), hence the third statement is true.

Explanation:

To answer your question, we need to substitute 1 and 3 into the function f(x)=-2x^2+3x+10, respectively. So:

For f(1), we get -2*1^2 + 3*1 + 10 = -2 + 3 + 10 = 11.

For f(3), we get -2*3^2 + 3*3 + 10 = -18 + 9 + 10 = 1.

Therefore, we can clearly see that the value of f(1) is larger than the value of f(3), meaning the third statement is true.

write two linear functions, f(x) and g(x). For example, f(x)= 3x-7 and g(x)= -2x+5. Then see whether f(x) - (-g(x)) is equivalent to f(x) + g(x).

Answers

Answer:

the two expressions are equivalent.

Step-by-step explanation:

We know that f(x)= 3x-7 and g(x)= -2x+5, therefore:

f(x) - (-g(x)) = 3x-7 - ( +2x-5) = 3x - 7 - 2x + 5 = x -2

f(x) + g(x) = 3x-7 -2x + 5 = x - 2

Therefore,  f(x) - (-g(x)) is equivalent to f(x) + g(x).

Another way to check that the two expressions are equivalent is by solving the parenthesis:

f(x) - (-g(x)) →  f(x) + g(x)

Therefore, the two expressions are equivalent.

x^y=y^x find derivitive

Answers

Answer:

[tex]y'=\frac{y^2-xy\ln(y)}{x^2-xy\ln(x)}[/tex]

Step-by-step explanation:

Take natural log of both sides first.

[tex]x^y=y^x[/tex]

[tex]\ln(x^y)=\ln(y^x)[/tex]

Taking the natural log of both sides allows you to bring down the powers.

[tex]y\ln(x)=x\ln(y)[/tex]

I'm going to differentiate both sides using the power rule.

[tex](y)'(\ln(x))+(\ln(x))'y=(x)'(\ln(y))+(\ln(y))'x[/tex]

Now recall (ln(x))'=(x)'/x=1/x while (ln(y))'=(y)'/y=y'/y.

[tex]y'(\ln(x))+\frac{1}{x}y=1(\ln(y))+\frac{y'}{y}x[/tex]

Simplifying a bit:

[tex]y' \ln(x)+\frac{y}{x}=\ln(y)+\frac{y'}{y}x[/tex]

Now going to gather my terms with y' on one side while gathering other terms without y' on the opposing side.

Subtracting y'ln(x) and ln(y) on both sides gives:

[tex]\frac{y}{x}-\ln(y)=-y'\ln(x)+\frac{y'}{y}x[/tex]

Now I'm going to factor out the y' on the right hand side:

[tex]\frac{y}{x}-\ln(y)=(-\ln(x)+\frac{x}{y})y'[/tex]

Now we get to get y' by itself by dividing both sides by (-ln(x)+x/y):

[tex]\frac{\frac{y}{x}-\ln(y)}{-\ln(x)+\frac{x}{y}}=y'[/tex]

Now this looks nasty to write mini-fractions inside a bigger fraction.

So we are going to multiply top and bottom by xy giving us:

[tex]\frac{y^2-yx\ln(y)}{-xy\ln(x)+x^2}=y'[/tex]

[tex]y'=\frac{y^2-xy\ln(y)}{x^2-xy\ln(x)}[/tex]

The derivative of the implicit function [tex]x^y = y^x[/tex] is [tex]\[\frac{dy}{dx} = \frac{\ln(y) - \frac{y}{x}}{\ln(x) - \frac{x}{y}}\][/tex].

To find the derivative of the implicit function defined by [tex]\( x^y = y^x \),[/tex] follow these steps:

Take the natural logarithm of both sides to simplify the expression:

        [tex]\ln(x^y) = \ln(y^x)[/tex]

Using logarithm properties, this becomes:

        y ln(x) = x ln(y)

Differentiate both sides with respect to x. Use implicit differentiation where y is considered a function of x:

For the left side, differentiate y ln(x):

        [tex]\[ \frac{d}{dx}[y \ln(x)] = \frac{dy}{dx} \ln(x) + y \cdot \frac{1}{x} \][/tex]

For the right side, differentiate x ln(y):

        [tex]\[ \frac{d}{dx}[x \ln(y)] = \ln(y) + x \cdot \frac{1}{y} \cdot \frac{dy}{dx} \][/tex]

Set the derivatives equal to each other:

        [tex]\[ \frac{dy}{dx} \ln(x) + \frac{y}{x} = \ln(y) + \frac{x}{y} \cdot \frac{dy}{dx} \][/tex]

Solve for [tex]\( \frac{dy}{dx} \):[/tex]

Rearrange terms involving [tex]\( \frac{dy}{dx} \):[/tex]

        [tex]\[ \frac{dy}{dx} \ln(x) - \frac{x}{y} \cdot \frac{dy}{dx} = \ln(y) - \frac{y}{x} \][/tex]

Factor out [tex]\( \frac{dy}{dx} \):[/tex]

        [tex]\[ \frac{dy}{dx} \left(\ln(x) - \frac{x}{y}\right) = \ln(y) - \frac{y}{x} \][/tex]

Finally, solve for [tex]\( \frac{dy}{dx} \):[/tex]

Equivalent expressions may be generated by distributing a factor such as [tex](-1)(-x^2+50x-9)[/tex], but the polynomial does not factor nicely over the integers for other simplifications.

Explanation:

To find two equivalent expressions for the opposite of the polynomial [tex]-x^2+50x-9[/tex], we start by taking the opposite of the given polynomial. The opposite (or negative) of a polynomial consists of changing the sign of each term. Therefore, the opposite of the given polynomial is [tex]x^2 - 50x + 9.[/tex]

An equivalent expression can be obtained by factoring, if possible, or by using other algebraic manipulations. However, in this case, [tex]x^2 - 50x + 9[/tex] does not factor nicely over the integers. To get an equivalent expression, we can express it in different forms, such as:

Distributing a factor: [tex](-1)(-x^2 + 50x - 9)[/tex]Factoring by grouping (though not applicable to this specific polynomial)

[tex]2\sqrt{5} 2\sqrt{5}=4(5)=20[/tex]

So, the first expression matches with 8.

The second expression matches with the square root of seven.

The third expression matches with one-half.

The fourth expression matches with 20.

what is the input-output table for the function f(x) = 3x^2-x+4

Answers

Answer:

Step-by-step explanation:

The input-output table can be made by putting value of x and finding the value of f(x)

f(x) = 3x^2-x+4

f(0) = 3(0)^2-0+4 = 0-0+4 = 4

f(1) = 3(1)^2-1+4 = 3-1+4 = 2+4 =6

f(2) = 3(2)^2-2+4 = 3(4)-2+4 = 12-2+4 = 10+4 = 14

f(3) = 3(3)^2-3+4 = 3(9)-3+4 = 27-3+4 = 24+4 = 28

So put value of x and find f(x) and fill the input-output table.

x  f(x)

0   4

1    6

2   14

3    28

What are the solutions of 4x2-x+9=0

Answers

For this case we must find the solutions of the following equation:

[tex]4x ^ 2-x + 9 = 0[/tex]

We apply the cudratic formula:

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]

Where:

[tex]a = 4\\b = -1\\c = 9[/tex]

Substituting:

[tex]x = \frac {- (- 1) \pm \sqrt {(- 1) ^ 2-4 (4) (9)}} {2 (4)}\\x = \frac {1 \pm \sqrt {1-144}} {8}\\x = \frac {1 \pm \sqrt {-143}} {8}[/tex]

Thus, the complex roots are:

[tex]x_ {1} = \frac {1 + i \sqrt {143}} {8}\\x_ {2} = \frac {1-i \sqrt {143}} {8}[/tex]

Answer:

[tex]x_ {1} = \frac {1 + i \sqrt {143}} {8}\\x_ {2} = \frac {1-i \sqrt {143}} {8}[/tex]

Which coordinates will best represent point A'?

A. (-2, 5)

B. (4, -3)

C. (-2, -3)

D. (4, 5)​

Answers

Answer: OPTION A.

Step-by-step explanation:

You know that the rule that will be used for the translation of the figure ABC is:

[tex](x,y)[/tex]→[tex](x-3,\ y+4)[/tex]

You can observe in the figure that the coordinates of the point A is this:

[tex]A(1,1)[/tex]

Then, in order to find the coordinates that will best represent point A', you need to subtract 3 from the x-coordinate of the point A and add 4 to the y-coordinate of the point A:

[tex]A'(1-3,\ 1+4)\\\\A'(-2,5)[/tex]

Answer:

A. (-2,5)

Step-by-step explanation:

The figure ABC is translated to A'B'C' by the rule (x-3, y+4)

The Image of the triangle will therefore be as follows:

A' (1-3,1+4)

B'(2-3,5+5)

C'(3-3,2+5)

The vertices will thus be A'(-2,5), B'(-1,10) and C'(0,7)

Thus the correct answer will be A. (-2,5)
