Answer:

[(-15, 21), (-6, 12).(-1, 7)}

Step-by-step explanation:

we have

x+y=6

Find the values of y for XE (-15, -6, -1)

so

For x=-15

-15+y=6 --->y=21

therefore

a solution is the point (-15,21)

For x=-6

-6+y=6 --->y=12

therefore

a solution is the point (-6,12)

For x=-1

-1+y=6 --->y=7

therefore

a solution is the point (-1,7)

The set of ordered pairs that are solutions is

[(-15, 21), (-6, 12).(-1, 7)}

Final answer:

The correct set of ordered pairs, which are the solutions to the equation x + y = 6 given x in {-15, -6, -1}, is {(-15, 21), (-6, 12), (-1, 7)}.

Explanation:

To determine which set of ordered pairs are solutions to the given equation x + y = 6, we need to plug the x-values into the equation and solve for y.

The correct set of ordered pairs is therefore {(-15, 21), (-6, 12), (-1, 7)}.

Answer: 0.2

Step-by-step explanation:

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]

[tex]4x=12[/tex]

[tex]x=\frac{12}{4}[/tex]

[tex]x=3[/tex]

Finally the solution is:

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

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

{23, 31, 39, 47, 55,.....,n}

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.

With [tex]a_{1}=23[/tex], and d = 8:

[tex]a_{n} =23+8(n-1)[/tex]

[tex]a_{n} =23+8n-8[/tex]

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

Step-by-step explanation:

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

Answer:

$1,466.23 Will be your answer mate !!!!!!

Step-by-step explanation:

The present value is calculated by discounting each of the cash flows to the present therefore if we assume no salvage value:  

PV = $100 / 1.08 + $100 / 1.08^2 + $100 / 1.08^3 + $200 / 1.08^4 + $300 / 1.08^5 + $600 / 1.08^6  

PV = $923.98  

Technically, as we have assumed there are no salvage value then in the future value will be zero. If you are asking how much remains in the investment. If you are asking how much the investment has yielded, keep in mind that the cash flows are not by definition reinvested so the time value of those cash flows can't be accounted for. If you do not account for the time value of those cash flows then the future value is just:  

$100 * 3 + $200 + $300 + $500 = $1,300  

However if you use the 8% per annum effective rate as a discount rate to take into consideration the time value of the money which is basically saying that you can reinvest the cash flows at 8% per annum effective then the future value would be:  

$100 * 1.08^5 + $100 * 1.08^4 + $100 * 1.08^3 + $200 * 1.08^2 + $300 * 1.08 + 500 = $1,466.23

you'll get your answer as : $1,466.23 !

Final answer:

The present value of the investment with varying cash flows and an 8% discount rate is $943.28. The future value, assuming reinvestment at an 8% interest rate until the end of Year 6, is $1,466.23.

Explanation:

To calculate the present value of the investment with varying cash flows and an 8% discount rate (interest rate), we discount each cash flow to its present value using the formula [tex]PV = FV / (1 + r)^t,[/tex]where PV is present value, FV is future value, r is the annual interest rate, and t is the number of years until the payment.

Year 1:  [tex]\$100 / (1 + 0.08)^1 = $92.59[/tex]

[tex]Year 2: \$100 / (1 + 0.08)^2 = $85.73 \\Year 3: \$100 / (1 + 0.08)^3 = $79.38 \\Year 4: \$200 / (1 + 0.08)^4 = $150.26 \\Year 5: \$300 / (1 + 0.08)^5 = $220.08 \\Year 6: \$500 / (1 + 0.08)^6 = $315.24 \\[/tex]

The sum of these values is the total present value of the investment, which equals $943.28.

For the future value, we grow each cash flow by the interest rate for the remaining period it would be invested until the end of Year 6, since payments are made at the end of each year.

[tex]Year 1: \$100 * (1 + 0.08)^5 = $146.93 \\Year 2: \$100 * (1 + 0.08)^4 = $136.05 \\Year 3: \$100 * (1 + 0.08)^3 = $125.97 \\Year 4: \$200 * (1 + 0.08)^2 = $233.28 \\Year 5: \$300 * (1 + 0.08)^1 = $324.00 \\[/tex]

Year 6: $500 = $500.00

By adding all future values, the total future value of the investment is $1,466.23.

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]

Step one: 3x+4y=20; 10=40-3y

Step two: 3y=40-10, so y=(40-10)/3=10

Step three: 3x+4*10=20

Step four: 3x=20-40=-20, so x=-20/3=-6.66666...~ -6.67

SA = (l x w x 2) + (l x h x 2) + (w x h x 2)

A. 88 square units.

Step-by-step explanation:

Volume formula:

 ↓

[tex]V=L*W*H[/tex]

[tex]6*4*2=48[/tex]

[tex]L*H*2[/tex]

[tex]6*2*2=24[/tex]

[tex]W*H*2[/tex]

[tex]4*2*2=16[/tex]

Add the numbers from left to right.

48+24=72

72+16=88

88 is the correct answer.

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

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.

Answer:

12

Step-by-step explanation:

Volume of cylinder is pi*r^2*h    (this is equal to 540pi in this case)

So we have 540pi=pi*r^2*h  

this means that 540=r^2*h   (I just divided both sides by pi since both sides were being multiplied by pi)

The height,h, is 15 so plug in 540=r^2*15

Divide both sides by 15 giving 540/15=r^2

So r^2=36

So r=6

The diameter,d, is twice the radius, r.

So d=2(6)=12

Answer:

b. 12

Step-by-step explanation:

The volume of a cylinder is

[tex]\pi {r}^{2} h[/tex]

Let us compose an equality and solve for the radius.

540pi = pi × r^2 × 15.

Divide both sides of the equation by 15pi.

r^2 = 36

r = +/- 6.

Length cannot be negative, so r = 6.

diameter = 2 × r. In this case,

d = 2 × 6 = 12.

The diameter is 12 ft.
