The number of solutions possible to a system of equations that include a conic section depends on the type of equations involved

<h3>How to determine the number of solutions?</h3>

A system of equation that has a conic section may or may not have solutions.

It would have a solution if the equations intersect, when plotted on a graph and it would not, if otherwise

A conic section can be any of:

  • Parabola
  • Ellipse
  • Hyperbola
  • Circle

<u>Example 1: No solution</u>

Consider the following system of equations

  • y = x² - 10 --- parabola equation
  • (x - 1)² + (y - 2)² = 5 --- circle

The above system of equations has no solution because they do not intersect when plotted on a graph (see graph 1)

<u>Example 2: One solution</u>

Consider the following system of equations

  • x = 2 --- linear equation
  • y = x² - 10 --- parabola

The above system of equations has one solution because they intersect at one point (see graph 2)

<u>Example 3: One solution</u>

Consider the following system of equations

  • y = 2x + 1 --- linear equation
  • y = x² - 10 --- circle

The above system of equations has two solutions because they intersect at two points (see graph 3)

The above examples imply that a system of equations that involves conic section can have as many solutions as possible.

The number of solutions depends on the type of equations involved

The attached graphs illustrate how a system of equations can have 0 to 4 solutions

Given that 1 x2 dx 0 = 1 3 , use this fact and the properties of integrals to evaluate 1 (4 − 6x2) dx. 0
Debora [2.8K]

So, the definite integral  \int\limits^1_0 {(4 - 6x^{2} )} \, dx= - 74

Given that

\int\limits^1_0 {x^{2} } \, dx = 13

We find

\int\limits^1_0 {(4 - 6x^{2} )} \, dx

<h3>Definite integrals </h3>

Definite integrals are integral values that are obtained by integrating a function between two values.

So, Integral \int\limits^1_0 {(4 - 6x^{2} )} \, dx

So, \int\limits^1_0 {(4 - 6x^{2} )} \, dx = \int\limits^1_0 {4} \, dx - \int\limits^1_0 {6x^{2} } \, dx \\=  4[x]^{1}_{0}    - \int\limits^1_0 {6x^{2} } \, dx \\=  4[x]^{1}_{0}    - 6\int\limits^1_0 {x^{2} } \, dx \\= 4[1 - 0]    - 6\int\limits^1_0 {x^{2} } \, dx\\= 4[1]    - 6\int\limits^1_0 {x^{2} } \, dx\\= 4    - 6\int\limits^1_0 {x^{2} } \, dx

Since

\int\limits^1_0 {x^{2} } \, dx = 13,

Substituting this into the equation the equation, we have

\int\limits^1_0 {(4 - 6x^{2} )} \, dx = 4 - 6\int\limits^1_0 {x^{2} } \, dx\\= 4 - 6 X 13 \\= 4 - 78\\= -74

So, \int\limits^1_0 {(4 - 6x^{2} )} \, dx= - 74

A boat sails on a bearing of 77 degrees for 135 miles and then turns and sails 207 miles on a bearing of 192 degrees. Find the d
Andrew [12]

Answer:

193.53 miles

Step-by-step explanation:

Please see the diagram for understanding of how the angles were derived,

Applying Alternate Angles, ABO =77 degrees

The bearing from B to C is 192=180+12 degrees

Subtracting 12 from 77, we obtain the angle at B as 65 degrees.

We want to determine the boat's distance from its starting point.

In the diagram, this is the line AC.

Applying Law of Cosines:

b^2=a^2+c^2-2acCosB\\b^2=207^2+135^2-2(207)(135)Cos65^\circ\\b^2=37453.8654\\b=\sqrt{37453.8654} \\b=193.53\: miles

The distance of the boat from its starting point is 193.53 miles (correct to 2 decimal places).

Why is the absolute value of every number positive
bekas [8.4K]

Answer:

because you can't get closer to 0 on the number line than 0 units away.

Step-by-step explanation:

it's like walking if the point is 3 foot in front of you and you walk to it once you get to it then even if you keep walking you can't go a negative number of feet away from it because the closest you can get is right on it.

Find the area. Do you multiply all sides?
arlik [135]

Answer:

Step-by-step explanation:

I think you are to assume that this is a trapezoid and that the top right angle symbol is missing.

Area = (b1 + b2 ) *  h /2

Givens

b1 = 2

b2 = 6.2

h = 3

Solution

Area = (2 + 6.2)* 3 / 2           Combine what is inside the brackets

Area = 8.2 * 3 / 2                  Divide by 2

Area = 4.1 * 3                         Combine

Answer: Area = 12.3
