The answer would be Y= 1/2x -5
Answer:
Here x² + z² ≤ 49 which describes the set of all points whose distance from the y-axis is at most 7 .Thus, the inequality represents the region consisting of all points on or inside a circular cylinder of radius 7 with axis the Y-axis
Step-by-step explanation:
The equation given is equivalent to . This square root, by the pythagorean theorem, represents the distance of a point (x,y,z) to the y axis( that is, to the point (0,y,0) ). There are no constraints in y, so for a fixed value of y, these points lie inside the plane of height y and inside the circle of radius 7 centered at (0,y,0). Taking y as a variable, we join all of these circles alongside the y- axis and obtain a cylinder of radius 7.
<h2>15 + 36 greater-than 41, so the side lengths will form a triangle.</h2>
15 + 36 not-equals 41, so those lengths will not form a triangle.
15 squared + 36 squared = 1,521
41 squared = 1,681
Since a squared + b squared not-equals c squared, it will not be a right triangle.
15 squared + 36 squared = 297
41 squared = 82

Answer:
The volume of a 3D figure can be determined by the sum of all the cross-sections of that 3D figure parallel to the base
Step-by-step explanation:
<u>We need to understand what a cross-section of a 3D figure ? </u>
A cross section is the shape we get when cutting straight through an object
and in geometry it is the shape made when a solid is cut through by a plane.
=> the cross section is parallel to the base of the figure.
So that the area of the cross-section is determined by its shape
Hence, The volume of a 3D figure can be determined by the sum of all the cross-sections of that 3D figure parallel to the base
