Answer:
Step-by-step explanation:
product= multiply
x*4=8 aka 8/4=2
so x=2
15-8=7
The slope is 3.
10 - 7 = 3
4 - 3 = 1
Final step is to do 3 divided by 1 and you get 3.
Answer: (b) The focus of an ellipse is always located precisely at the center of the ellipse.
Step-by-step explanation:
An ellipse is defined as <em>"a closed curve with two axes of symmetry (major axis and minor axis) that results in cutting the surface of a cone by an oblique plane to the axis of symmetry with an angle greater than that of the generatrix with respect to the axis of revolution"</em>. That is why the ellipse is considered a conic figure.
To understand it better: an ellipse has two points on its major axis that are equidistant from the center , which are called foci, being this distance constant. In addition, the eccentricity allows to know how far the foci are from the center of the ellipse.
Therefore, the statement that indicates an ellipse has only one focus located precisely at the center is incorrect.
The ordered pair of the parking lot is the coordinates of the lot in the coordinate plane
Parking lot B is located in the ordered pair (-3,4)
<h3>How to determine the ordered pair of lot B</h3>
From the figure, we have the following highlights
Parking lot B is located at x = -3 on the horizontal axis, and it is located at y = 4 on the vertical axis.
So, we have:
(x,y) = (-3,4)
Hence, parking lot B is located in the ordered pair (-3,4)

Answer: 294.4 m²
<u>Step-by-step explanation:</u>
Separate the shaded region into two parts:
- The section containing the central angle of 230° (360° - 130°)
- The triangle with sides 11.1, 11.1 & 20.12 (use Law of Cosines)
Area of shaded region = Area of (1) + Area of (2)
= 247.3 + 47.1
= 294.4
