Which describes the scatter plot of a car’s value compared to the age of the car ?

Answer:

y-6 = -3(x+1)

Step-by-step explanation:

The point-slope form of a line is the following:

y-yo = m(x-xo), where 'm' is the slope and (xo, yo) is any point where the line passes through.

In this case, m=-3 and (xo, yo) = (-1, 6).

Therefore: y-yo = m(x-xo) = y-6 = -3(x+1)

In conclusion, the point-slope form of the equation that represents the line that passes through the point (-1, 6) and has a slope of -3 is:

y-6 = -3(x+1)

For this case we have that the equation of a line in the point-slope form is given by:

[tex](y-y_ {0}) = m (x-x_ {0})[/tex]

Where:

m: It's the slope

[tex](x_ {0}, y_ {0})[/tex]: It is a point through which the line passes

According to the data we have to:

[tex]m = -3\\(x_ {0}, y_ {0}) = (- 1,6)[/tex]

So the equation is:

[tex](y-6) = - 3 (x - (- 1))\\(y-6) = - 3 (x + 1)[/tex]

Answer:

[tex](y-6) = - 3 (x + 1)[/tex]

Answer:

h = 147 - 16t^2.

Step-by-step explanation:

Use the following equation of motion

h = ut + 1/2 gt^2    where  h = height, u = initial velocity , g = acceleration due to gravity and t = the time.

So here we have:

h = 14t + 1/2 * -32 * t^2

h = 14t - 16t^2

Answer:

Height of jump, s(t) = 14t - 16.09t²

Step-by-step explanation:

We have equation of motion s = ut + 0.5 at².

For the this vertical motion we have

              s = height of jump

              u = initial velocity = 14 ft/s

               t = time

               a = acceleration due to gravity = -32.17 ft/s²

Substituting

                 s = 14 x t + 0.5 x (-32.17) x t²

                 s = 14t - 16.09t²

Height of jump, s(t) = 14t - 16.09t²

Answer:

$878.25

Step-by-step explanation:

Continuously compounded interest is:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the interest rate, and t is the number of compoundings.

Here, P = 560, r = 0.09, and t = 5.

A = 560e^(0.09×5)

A = 878.25

Final answer:

To calculate the future value of an investment compounded continuously, use the formula A = Pert. In this case, the investment will be worth approximately $877.29 in 5 years.

Explanation:

To calculate the future value of an investment compounded continuously, we can use the formula A = Pert, where A is the future value, P is the initial principal, r is the annual interest rate, and t is the time in years. In this case, P = $560, r = 0.09, and t = 5. Plugging these values into the formula, we get:

A = 560e^(0.09⋅5)

A ≈ 560e^0.45

A ≈ 560 ⋅ 1.5662

A ≈ $877.29

Therefore, the investment will be worth approximately $877.29 in 5 years.

Step-by-step explanation:

We need to set f(x) = 0 to find the values of x for this expression.

So

[tex]x^3-5x^2-6x=0[/tex]

We will factor out an x and do middle term factorization to arrive at our answer for x (there will be 3 x values):

[tex]x^3-5x^2-6x=0\\x(x^2-5x-6)=0\\x(x-6)(x+1)=0\\x=0,6,-1[/tex]

These are the 3 values for x.

Answer:

x = 4

Step-by-step explanation:

Given

4x - 6 + 2x = 18 ← simplify left side by collecting like terms

6x - 6 = 18 ( add 6 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

The solution to the equation 4x - 6 + 2x = 18 is x = 4.

To solve the equation 4x - 6 + 2x = 18, we need to combine like terms and isolate the variable x.

First, let's combine the like terms on the left side of the equation:

4x + 2x - 6 = 18

This simplifies to:

6x - 6 = 18

Next, we can isolate the variable x by adding 6 to both sides of the equation:

6x - 6 + 6 = 18 + 6

This simplifies to:

6x = 24

To solve for x, we can divide both sides of the equation by 6:

(6x)/6 = 24/6

This simplifies to:

x = 4

Therefore, the solution to the equation 4x - 6 + 2x = 18 is x = 4.

Answer:

$409.86

Step-by-step explanation:

230 is the before markup

We must apply the markup (or even discount) before the tax is applied.

Marked up 65% means we must do .65(230)  <---This will tell us how much more the tent is going to sell for

.65(230)=149.5

So we started with 230 and it is going up by 149.5, so the new price before tax is 230+149.5=379.5

Now the tax is applied to what you are paying (before tax).

So 8% of 379.5 is .08(379.5)=30.36

So new price + tax is the total cost

    379.5        +30.36

Answer:

r=3

Step-by-step explanation:

24π=2π(r^2+r)

Divide each side by 2 pi

24π/2π =2π/2π(r^2+r)

12 = r^2 +r

Subtract 12 from each side

12-12 = r^2 +r -12

0 =  r^2 +r -12

Factor

What number multiply to -12 and add to 1

4*-3 = -12

4-3 = 1

0= (r+4) (r-3)

Using the zero product property

r+4 =0          r-3 =0

r+4-4 =0-4   r-3+3=0+3

r = -4           r = -3

Answer: Option C

[tex]y=5[/tex], [tex]x=10[/tex]

Step-by-step explanation:

If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.

By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a', b',  c'  then:

[tex]\frac{a}{a'}=\frac{b}{b'} =\frac{c}{c'}[/tex]

In this case

[tex]a = 12\\a' = 4\\c = 15\\c' = y[/tex]

So:

[tex]\frac{12}{4}=\frac{15}{y}[/tex]

Now solve the equation for the variable y

[tex]3=\frac{15}{y}[/tex]

[tex]y=\frac{15}{3}[/tex]

[tex]y=5[/tex]

We know that

[tex]x+y=15[/tex] and  [tex]y=5[/tex]

Answer:

The side of the square = x/√2

Step-by-step explanation:

All the sides of a square are equal. All the angles are equal to 90°

To find the side of a square

From the figure attached with this answer shows a square.

Let 'x' be the diagonal of the square.

The diagonal make two right angled triangle with angle 45°, 45° and 90°

Therefore the sides are in the ratio 1 : 1 : √2

Here diagonal = x

 side : side : x= side : side : √2

Therefore one side length = x/√2

Answer:

Area = x²/2 square units

Step-by-step explanation:

The key to solving this question is to understand that:

a) the sides of a square are the same length

b) the length of the diagonal may be calculated via Pythagoras' theorem (c² = a² + b², where c is the length of the hypotenuse of a triangle and a and b the lengths of the other two sides)

1. Now, let's call the sides of the square length y and the diagonal is length x.

Using c² = a² + b², we can substitute our values to get:

x² = y² + y²

x² = 2y²

2. Stepping away from Pythagoras' theorem for a little bit, let us think of the general formula for the area of a square:

A (for Area) = a², where a is the length of the sides of the square (which are all of equal length)

Given that we defined our square as having length y, let us substitute this value in to get:

A = y²

3. Now we have two formulas that we can work with:

1) x² = 2y²

2) A = y²

4. Given that A = y², we can say that 2y² = 2A

Therefor, if x² = 2y², then x² = 2A

Thus, if we want to find the formula for area in terms of x, we need to simply rearrange the given formula to make A the subject, giving us:

A = x²/2 square units
