Answer:

The conic is parabola, its equation is (y + 5)² = -(x + 1)

Step-by-step explanation:

- The general equation for any conic section is  

Ax² + Bxy + Cy² + Dx + Ey + F = 0  

where A , B , C , D , E and F are constants. A, B, and C are not all zero

- When we change the values of some of the constants, the shape  

of the corresponding conic will also change.  

- It is important to know the differences in the equations to  

identify the type of conic that is represented by a given equation.  

# If B² − 4AC is less than zero, if a conic exists, it will be either a  

circle or an ellipse  

# If B² − 4AC equals zero, if a conic exists, it will be a parabola  

# If B² − 4AC is greater than zero, if a conic exists, it will be a  

hyperbola  

* How to identify the type of the conic

- Rewrite the equation in the general form,  

Ax² + Bxy + Cy² + Dx + Ey + F = 0  

- Identify the values of A and C from the general form.  

- If A and C are nonzero, have the same sign, and are not equal

to each other, then the graph is an ellipse.

- If A and C are equal and nonzero and have the same sign, then

the graph is a circle  

- If A and C are nonzero and have opposite signs, and are not equal

then the graph is a hyperbola.

- If either A or C is zero, then the graph is a parabola

* Now lets solve the problem

- The equation is y² + x + 10y + 26 = 0

 A = 0 , B = 0 , C = 1 , D = 1 , E = 10 and F = 26

∵ A = 0

∴ The equation is a parabola its standard form is:

  (y - k)² = 4 p (x - h), where (h , k) is the vertex point of the parabola,

   with a horizontal axis y = k

- Lets change the standard form to the general form

∵ (y - k)² = 4 p (x - h) ⇒ open the brackets

∴ y² - 2ky + k² = 4px - 4ph

- Put all of them in one side

∴ y² - 4px - 2ky + k² + 4ph = 0

- Compare it with the equation

  y² - 4px - 2ky + k² + 4ph = 0 ⇒ y² + x + 10y + 26 = 0

∵ -4px = 1x ⇒ cancel x

∴ -4p = 1 ⇒ divide both sides by -4

∴ p = -1/4

∵ -2ky = 10y ⇒ cancel y

∴ -2k = 10 ⇒ divide both sides by -2

∴ k = -5

∵ k² + 4ph = 26 ⇒ (-5)² + 4(-1/4)h = 26 ⇒ simplify

∴ 25 - h = 26 ⇒ subtract 25 from both sides

∴ h = -1

- Now we can write the standard form of the equation

∴ (y - -5)² = 4(-1/4)(x - -1)

∴ (y + 5)² = -(x + 1)

Answer:

a)  60°

b)  60°

Step-by-step explanation:

A regular hexagon can be broken down into 6 equilateral triangles.

*** Note: Attached picture shown.

a)

The angle between two consecutive radii would be taken as EO and OD.

Since all of these 6 angles (of 6 triangles) create a circle, the sum is 360. So each angle (between two radii) would be 360/6 = 60°

b)

To find angle between side and radius of a polygon, let's take the radii as EO and side as ED.

Since we already found the angle between 2 radii to be 60, we have two angle left of a triangle (same size, let's call it x). We know sum of 3 angles in a triangle is 180, thus we can write:

60 + x + x = 180

60 + 2x = 180

2x = 180 - 60

2x = 120

x = 120/2

x = 60°

Answer:

The range is defined as the difference between the term with the highest value and the term with the lowest value. This statistic is used to measure the variability of a series of data because it provides information on how far apart the values of a tail of the distribution are from the values at the other end of the tail.

Imagine that you manufacture a type of spare part for cars that must have a measurement of 10 cm with a margin of error of 1 cm.

This is:

10 ± 1 cm

Then you expect your manufacturing process to produce pieces with identical dimensions, that is, with little variability.

If you randomly select a sample of n pieces and measure them, the variability is expected to be low, so that your process is of quality, then expect a low range preferably less than 1 cm.

{10, 10.1, 10.5, 9.8, 9,6, 10.2} Range= 10.5 - 9.6 = 0.9 cm low variability

But if you find that the range is up to 8 cm, this would mean that not all pieces measure around 10 cm, it means that the variability of the measurements is high.

{14, 12, 11, 8, 7, 11, 12, 15} Range = 15 - 7 = 8 cm   high variability

The range can help describe a data set by evaluating the whole of a data set, showing spread within a data set, and comparing the spread between similar data sets. Simply put, it is the amount of variation from the lowest number to the highest and indicates the size of the statistical dispersion.

Answer:

a + 2b

Step-by-step explanation:

To find the equivalent of the given expression, we must open up the parenthesis by multiplying each element in the parenthesis by 2, we would then collect like terms and simplify the algebraic expression.

2(a + 2b) - a - 2b

= 2a + 4b - a - 2b

= 2a - a + 4b  - 2b

= a + 2b

Where the opposite side is 3 and the hypotenuse is 8.

Substitute all the values in the formula;

[tex]\rm Sin\theta = \dfrac{opposite \ side}{Hypotenuse}\\\\\rm Sin\theta = \dfrac{3}{8}\\\\\theta = sin{-1} \left ( \dfrac{3}{8} \right )\\\\\theta = 22.02 \ degrees[/tex]

Answer:

27 in^2

Step-by-step explanation:

   To solve this, we must first find the height. We can split the trapezoid into a triangle and rectangle! Since 11-7=4, one of the legs of the triangle is 4, and the height of the trapezoid is 3 because 3,4,5 is a pythagorean triple. Since the area of a trapezoid is the average of the bases times the height, we multiply 9, the average, by 3 and we get 27 in^2.

Answer: OPTION A

Step-by-step explanation:

The formula that is used to calculate the surface area of a cone is:

[tex]SA=\pi rl+\pi r^2[/tex]

Where "r" is the radius and "l" is the slant height.

You can identify in the figure that:

[tex]l=12units\\r=3units[/tex]

Then, you need to substitute these values into the formula [tex]SA=\pi rl+\pi r^2[/tex].

Therefore, the surface area of this right cone is:

[tex]SA=\pi (3units)(12units)+\pi (3units)^2[/tex]

[tex]SA=45\pi\ units^2[/tex]

Answer:

Option D

Step-by-step explanation:

The equation to predict the amount saved is

[tex]y = 6x ^ 2 + 75x + 200.[/tex]

Assuming that the variable x represents the saving months, then substitute [tex]x = 25[/tex] in the quadratic equation and solve for y.

[tex]y = 6 (25) ^ 2 +75 (25) +200\\\\y = \$\ 5,825[/tex]

The answer is the option D  $5,825

It will take approximately 14.2 years for the money to triple in the savings account.

Step 1: Set up the formula and define variables

We know the initial amount (P) is $600, and we want the final amount (A) to be triple the initial amount, which is 3 * $600 = $1800. The interest rate (r) is 4.8% (converted to decimal: 0.048) and we want to find the time (t) in years.

We'll use the compound interest formula continuously compounded: A = Pe^rt.

Step 2: Solve for time (t)

We can rewrite the formula to solve for t: t = ln(A/P) / r

Plug in the known values:

t = ln($1800 / $600) / 0.048

Step 3: Solve and round

Calculate the result using a calculator and round to the nearest tenth of a year.

t ≈ 14.2 years

Answer: Option C

[tex]f(x) = x^2;\ k (x) = x ^ 2 -7[/tex]

Step-by-step explanation:

Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:

[tex]k (x) = f (x) + b[/tex]

If [tex]b> 0[/tex] then the graph of k(x) will be the graph of f(x) displaced vertically b units down.

If [tex]b> 0[/tex] then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.

In this case we have

[tex]f (x) = x ^ 2[/tex]

We know that this function has its vertex in point (0,0).

Then, to move its vertex 7 units down we apply the transformation:

[tex]k (x) = f (x) - 7\\\\k (x) = x ^ 2 -7[/tex].

Then the function k(x) that will have its vertex 7 units below f(x) is

[tex]k (x) = x ^ 2 -7[/tex]
