You bought a guitar 6 years ago for $400. It's value decreases by about 13% per year. Write a formula to show the value of the guitar over those six years and determine its current value

Answer:

  29

Step-by-step explanation:

The perimeter is the sum of the side lengths:

  4 + 12 + 13 = 29

The perimeter of the triangle is 29. (It is not a right triangle.)

___

A right triangle with side lengths 12 and 13 will have a short side of 5. Its perimeter is 30.

Your answer is the last option, -148°F

The formula to convert temperatures from Celcius to Farenheit is:
(C° x 9/5) + 32 or (C° x 1.8) + 32

So to solve, plug in -100°C and follow the order of operations (PEMDAS).

(-100 x 1.8) + 32
(-180) + 32
-148

-100°C is equal to -148°F

The freezing point of the antifreeze solution in Fahrenheit is -148 °F, calculated using the formula for converting Celsius to Fahrenheit.

To convert a temperature from the Celsius scale to the Fahrenheit scale, you can use the following formula: F = (C  imes 9/5) + 32, where F represents the Fahrenheit temperature, and C represents the Celsius temperature.

In this case, we are given the freezing point of an antifreeze solution, which is -100 °C. Applying the formula, we get F = (-100 x 9/5) + 32. This calculation gives us F = (-180) + 32, which simplifies to F = -148 °F.

So, the freezing point of the antifreeze solution on the Fahrenheit scale is -148 °F.

│FV│ = │VD│

Being D the directrix. Given that the focus F is on the y-axis and the directrix is parallel to the x-axis, then the vertex V will also be on this axis, so h = 0.

As │FV│ = │VD│, then:

[tex]k = \frac{6-2}{2}[/tex], that is the middle point of the segment FD, so:

V(0,2)

Now │FV│= │p│= │2-(-2)│=4

Given that the vertex and focus are below the directrix, then the parabola open down, therefore: [tex]p\ \textless \ 0[/tex]

Lastly, the equation is:

[tex]x^{2} = -4(4)(y-2) = -16y+32[/tex]
[tex]y = -\frac{ x^{2} }{16} + 2[/tex]

The equation of a parabola with a focus at (0,-2) and a directrix of y=6 is x^2 = -16(y - 2).

To find the equation of a parabola with a focus at (0,-2) and a directrix of y=6, you need to use the standard form of the equation of a parabola that opens upwards or downwards. The general form of this type of parabola is  (x - h)^2 = 4p(y - k), where (h,k) is the vertex of the parabola, and p is the distance from the vertex to the focus (if the parabola opens upwards or downward) or to the directrix (if the parabola opens sideway).

Given that the focus is at (0,-2) and the directrix is at y=6, the vertex of the parabola will be located midway between them. The distance between the focus and directrix is 8 units, so the vertex will be 4 units from each, which puts the vertex at (0, 2). Therefore, h=0 and k=2.

Since the focus is below the directrix, our parabola opens downward, and the value of p is negative. The distance p is half the distance between the focus and directrix, so p=-4. Plugging these values into the general form, we get (x - 0)^2 = 4(-4)(y - 2), which simplifies to x^2 = -16(y - 2).

This is the equation that represents the desired parabola.

The probability that a strawberry dessert contains whipped topping is approximately 69.2%

We are given that the probability a dessert contains strawberries (P(S)) is 26%, or 0.26, and the probability that a dessert contains both strawberries and whipped topping (P(S and W)) is 18%, or 0.18.

To find the probability that a randomly chosen strawberry dessert contains whipped topping (P(W|S)), we use the conditional probability formula:

[tex]P(W|S) = \frac{P(S and W)}{P(S)}[/tex]

Substituting the given values, we get:

[tex]P(W|S) = \frac{0.18}{0.26} \approx 0.6923[/tex]

Rounding to the nearest tenth of a percent we get the probability that a randomly chosen strawberry dessert contains whipped topping to be 69.2%.

Step-by-step explanation:

We have been given that Vivian's insurance company pays for 80% of her foot surgery, after she pays a $500 deductible. We have been given that her surgery costs $9600 and we need to find how much will Vivian have to pay for her surgery.

Since we know that the insurance company will pay any amount after Vivian has paid $500. Therefore, the remaining amount after Vivian pays $500 as deductibles will be $9600 - $500 = $9100.

Now we know that Vivian's insurance company will pay 80% of this amount, therefore, Vivian will have to pay the 20% of $9100 in addition to the $500 she already paid.

20% of $9100 is [tex]9100\cdot \frac{20}{100} = \$1820[/tex]

Therefore, the total amount that Vivian pays for surgery is $500 + $1820 = $2320.

Therefore, the first choice given is the right answer.

The average value have of the function h(u) = (15 − 10u)−1 on the given interval  [−1, 1] is -5.

The average value of a function is given by the formula:

[tex]fav = \frac{1}{b - a} \int\limits^b_a f({x}) \, dx[/tex]

Now the given function is,

h(u) = (15 − 10u) − 1

or, h(u) = 15 − 10u − 1

or, h(u) = 14 − 10u

So, the average value on the given interval [−1, 1] is given as:

[tex]fav = \frac{1}{1 - (-1)} \int\limits^1_{-1} h({u}) \, du[/tex]

Thus, putting the value of h(u) we get,

[tex]fav = \frac{1}{(1 + 1)} \int\limits^1_{-1} (14 - 10u) \, du[/tex]

Thus integrating we get,

fav = (1/2) { [14u] - [10u²/2]

⇒ fav = (1/2) { [14u] - [5u²]

Applying the limits we get, -1 to 1,

⇒ fav = (1/2) { 14[-1 + 1] - [5{-1² + 1²}]

Solving we get,

⇒ fav = (1/2) { 14[0] - [5{1 + 1}]

⇒ fav = (1/2) {- [5{2}]

⇒ fav = -5

Thus, the average value have of the function h(u) = (15 − 10u)−1 on the given interval  [−1, 1] is -5.

The correct answer is:

16√13.

Explanation:

The perimeter of a figure is found by adding together the lengths of all of the sides. The side lengths of this garden are: √13, √13, 7√13 and 7√13. This is because opposite sides in a rectangle are congruent.

Adding these together we have:

√13+√13+7√13+7√13 = (1+1+7+7)√13 = 16√13

By using the area of the ring we will see that the radius of the inner circle is 3cm.

I assume that we have some kind of ring. To get the area of the ring, we need to take the area of the circle defined by the outer radius of the ring, and subtract the area defined by the circle with the inner radius of the ring.

Remember that the area of a circle of radius R is:

A = pi*R^2

We know that:

The radius of the outer circle is 5cm, so its area is:

A = pi*(5cm)^2 = pi*25cm^2

And the area of the ring is pi*16 cm^2

Then the area of the inner circle should be such that:

pi*25cm^2 - A' = pi*16cm^2

Then, solving for A'

A' = pi*25cm^2 - pi*16cm^2 = pi*9cm^2 = pi*(3cm)^2

So the radius of the inner circle is 3cm.

The previous population of the city was 35000.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Assume the previous population to be [x].

Then, we can write -

x + 26% of x = 44100

x + 26x/100 = 44100

x + 13x/50 = 44100

(50x + 13x)/50 = 44100

63x = 44100 x 50

63x = 2205000

x = 35000

The previous population of the city was 35,000 before experiencing a 26% increase to the current population of 44,100.

To calculate the previous population of a city that has experienced a 26% increase to its current population of 44,100, we need to reverse the percentage increase. The formula for this is:

Previous population = Current population / (1 + Percentage increase)

In this case, the percentage increase is 26%, or 0.26 in decimal form. The calculation is:

Previous population = 44,100 / (1 + 0.26) = 44,100 / 1.26

This gives us:

Previous population = 35,000 (rounded to the nearest whole number)

Hence, the previous population of the city was approximately 35,000 before the 26% increase to the current 44,100.

Answer:

D) 40 miles

Step-by-step explanation:

First we must find the distance between the mall and the house.  The figure formed is a right triangle.  The length of the side from the mall to the house forms the hypotenuse of the triangle.  We can use the Pythagorean theorem to find the length:

a² + b² = c²

The two legs of the triangle, a and b, are 15 and 8:

15² + 8² = c²

225 + 64 = c²

289 = c²

Take the square root of each side:

√289 = √(c²)

17 = c

This makes the total distance

15+8+17= 40 miles

Hey! Pretty easy once you get the hang of these problems.

So you start off with the Pythagorean Theorem. Which is : a^2 + b^2 = c^2

Then just fill it in :

15^2 + 8^2 = c^2

225 + 64 = c2

289 = c^2

17 = c

And last :

15 + 8 + 17 = 40 MILES

hoped this helped!! :))
