Answer:

The quotient is 2x^2 - x + 1.

Step-by-step explanation:

If x + 1 is the divisor in long division, then -1 is the divisor in synthetic division:

-1   /   2    1    0    1

              -2    1    -1

    ----------------------

       2      -1     1    0

The quotient is 2x^2 - x + 1.  The coefficients were obtained through synthetic division.

Answer:

280 mL

Step-by-step explanation:

If x is the amount of 35% solution and y is the amount of pure water, then:

0.15 = (0.35x + 0y) / (x + y)

0.15 = (0.35x) / (x + y)

Given that x = 210 mL:

0.15 = (0.35×210) / (210 + y)

210 + y = 490

y = 280

Answer:

[tex]x=3\\y=-1\\\\(3,-1)[/tex]

Step-by-step explanation:

We have the following system of equations

[tex]4x-3y=15\\2x+2y=4[/tex]

To solve the system of equations multiply the second equation by -2 and add it to the first equation

[tex]-2*(2x+2y)=-2*4[/tex]

[tex]-4x - 4y=-8\\4x-3y=15[/tex]

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

[tex]-7y = 7\\y=-1[/tex]

Now substitute the value of y in any of the two equations and solve for the variable x

[tex]4x-3(-1)=15[/tex]

[tex]4x+3=15[/tex]

[tex]4x=15-3[/tex]

Step-by-step explanation:

Let's do the volume first. Volume of any prism is the area of the base times the height.

V = Ah

The base is a large square with a smaller rectangle cut from the corner, so its area is:

A = (14)(14) - (7)(10)

A = 126

So the volume is:

V = (126)(6)

V = 756 m^3

Now the surface area of a prism is the area of the bases plus the base perimeter times the height:

S = 2A + Ph

We already found the area of the base. Now we just have to add the perimeter times height.

S = 2(126) + (14 + 14 +7 + 10 + 7)(6)

S = 480 m^2

The expression 3log(2)3 - log(2)(x+4) can be simplified by using the logarithmic laws, resulting in the final single logarithm of log2(39 / (x+4)).

The original expression, 3log(2)3 - log(2)(x+4), can be simplified using a few laws of logarithms. Firstly, using the rule that the logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number, we can simplify. We find that the expression becomes log(2)33 - log(2)(x+4). Secondly, by applying the rule that the logarithm of the number resulting from the division of two numbers is the difference between the logarithms of the two numbers, we can further simplify. The final expression is now log2(39 / (x+4)). This is the expression written as a single logarithm.

Final answer:

To solve the equation 9x + 4 = 11 for x using the change of base formula log base b of y equals log y over log b, isolate x on one side of the equation, subtract 4 from both sides, then divide both sides by 9.

Explanation:

To solve the equation 9x + 4 = 11 for x using the change of base formula log base b of y equals log y over log b, we need to isolate x on one side of the equation. Here's how to do it:

Therefore, the solution to the equation is x = 7/9.

For this case we must find an expression equivalent to:

[tex]\frac {10x ^ 6y ^ {12}} {- 5x ^ {- 2} y^ {- 6}}[/tex]

We have to:

[tex]\frac {10} {- 5} = - 2[/tex]

Now, by definition of division of powers of equal base, we put the same base and subtract the exponents. Rewriting the expression we have:

x+1 +1 is the next number

The sum of these three number is

x + x+1 + (x+1+1) = 438

Combine like terms

3x +3 = 438

Subtract 3 from each side

3x+3-3 = 438-3

3x= 435

Divide by 3

3x/3=435/3

x = 145

x+1 =146

24 times 4 is 96 legs

196-96=100 divided by 2 is 50 humans

50 plus 24 is 74

Answer:

B 24 horses and 50 humans

Step-by-step explanation:

Let x = humans

y = horses

Each horse and human has 1 head, for a total of 74 heads

x+y = 74

Each human has 2 leags, 2x  and each horse has 4 legs, 4y for a total of 196 legs

2x+4y = 196

We have a system of equations

x+y = 74

2x+4y = 196

Multiply the first equation by -2

-2(x+y) = -2*74

-2x -2y - 154

Add the modified first equation to the second equation

-2x-2y = -154

2x+4y = 196

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

2y = 48

Divide by 2

2y/2 = 48/2

y = 24

There are 24 horses

x+y = 74

We know there are 24 horses

x+24 = 74

x+24-24 = 74-24

x=50

There are 50 humans

Explicit formula [tex]a_{n} =8n+15[/tex]

To solve this problem we have to use an arithmetic sequence. The cost of renting a kayak for 1 hour is $23, each additional hour is $8 more. So, the first element of the secuence will be 23 for one hour, then each addittional hour will be 23 + 8, making the secuence:

Writing a recursive formula of the form [tex]a_{n} =a_{n-1} +d[/tex] where [tex]a_{n}[/tex] is the nth term, n the number of terms, and d the common difference in the secuence.

The common difference of the secuence {23, 31, 39, 47, 55,.....,n}. So, the first term is [tex]a_{1} =23[/tex], and the common diffenece is d = 8 which is the difference between each term.

[tex]\left \{ {{a_{1} =23} \atop {a_{n} =a_{n-1}+8 }} \right.[/tex]

Writing a explicit formula of the form [tex]a_{n} =a_{1} +d(n-1)[/tex] where where [tex]a_{n}[/tex] is the nth term, n the number of terms, [tex]a_{1}[/tex] the first term of the secuence, and d the common difference in the secuence.

Answer:

So, the inverse of function

[tex]f(x) = \frac{-1}{2} \sqrt{x+3}[/tex] is [tex]f^{-1}(x)= 4x^2-3[/tex]

Step-by-step explanation:

We need to find the inverse of the given function

[tex]f(x) = \frac{-1}{2} \sqrt{x+3}[/tex]

To find the inverse we replace f(x) with y

[tex]y = \frac{-1}{2} \sqrt{x+3}[/tex]

Now, replacing x with y and y with x

[tex]x = \frac{-1}{2} \sqrt{y+3}[/tex]

Now, we will find the value of y in the above equation

Multiplying both sides by -2

[tex]-2x = \sqrt{y+3}[/tex]

Taking square on both sides

[tex](-2x)^2 = (\sqrt{y+3})^2[/tex]

[tex]4x^2 = y+3[/tex]  

Finding value of y

[tex]y = 4x^2-3[/tex]

Replacing y with f⁻¹(x)

[tex]f⁻¹(x)= 4x^2-3[/tex]

So, the inverse of function

[tex]f(x) = \frac{-1}{2} \sqrt{x+3}[/tex] is [tex]f^{-1}(x)= 4x^2-3[/tex]

ANSWER

[tex]f^{ - 1} (x) =4 {x}^{2}- 3[/tex]

EXPLANATION

A function will have an inverse if and only if it is a one-to-one function.

The given function is

[tex]f(x) = - \frac{1}{2} \sqrt{x + 3} \: \: where \: \: x \geqslant - 3 [/tex]

To find the inverse of this function, we let

[tex]y=- \frac{1}{2} \sqrt{x + 3}[/tex]

Next, we interchange x and y to get,

[tex]x=- \frac{1}{2} \sqrt{y+ 3}[/tex]

We now solve for y.

We must clear the fraction by multiplying through with -2 to get;

[tex] - 2x = \sqrt{y + 3} [/tex]

Square both sides of the equation to get:

[tex](- 2x)^{2} = (\sqrt{y+ 3}) ^{2} [/tex]

[tex]4x^{2} = y + 3[/tex]

Add -3 to both sides

[tex]4 {x}^{2} - 3 = y[/tex]

Or

[tex]y = 4 {x}^{2}- 3[/tex]

This implies that,

[tex]f^{ - 1} (x) =4 {x}^{2}- 3[/tex]

This is valid if and only if

[tex]x \geqslant - 3[/tex]
