Step-by-step explanation:
if it is leaking 3/4 in 1/2 h than it will leak 6/4 in one whole hour
<span>The correct answer is n</span>²<span>+3.
Explanation<span>:
We find the first differences between terms:
7-4=3; 12-7=5; 19-12=7; 28-19=9.
Since these are different, this is not linear.
We now find the second differences:
5-3=2; 7-5=2; 9-7=2.
Since these are the same, this sequence is quadratic.
We use (1/2a)n</span></span>²<span><span>, where a is the second difference:
(1/2*2)n</span></span>²<span><span>=1n</span></span>²<span><span>.
We now use the term number of each term for n:
4 is the 1st term; 1*1</span></span>²<span><span>=1.
7 is the 2nd term; 1*2</span></span>²<span><span>=4.
12 is the 3rd term; 1*3</span></span>²<span><span>=9.
19 is the 4th term; 1*4</span></span>²<span><span>=16.
28 is the 5th term: 1*5</span></span>²<span><span>=25.
Now we find the difference between the actual terms of the sequence and the numbers we just found:
4-1=3; 7-4=3; 12-9=3; 19-16=3; 28-25=3.
Since this is constant, the sequence is in the form (1/2a)n</span></span>²<span><span>+d;
in our case, 1n</span></span>²<span><span>+d, and since d=3, 1n</span></span>²<span><span>+3.</span></span>

Answer:
Circle 2
Step-by-step explanation:
Intercepted arc refers to a section of the circumference of a circle. The line segment ZV refers to the length of the arc. The central angle is the angle at the center of the circle between the two radii or line segments at the ends of the arc meeting at the center of the circle.
In the images below, it can be seen Circle 2 has line segment ZV with central angle of 58 degrees.
Circle 1 shows an inscribed angle which is the angle between two chords at their point of intersection on the circumference of the circle. A chord is a line joining two points on the circumference of a circle. In this case, one of the chords is the diameter of the circle
Circle 3 shows the angle between a chord and tangent intersecting on the circumference of the circle
Circle 4 also shows an inscribed angle. The chords are not crossing through the center of the circle
