Part A Assume the ball passes through the points ( 3 , 8 ) , ( 5 , 20 3 ) , and ( 6 , 5 ) . Use this data to set up a system of

three equations and three unknowns (a, b, and c) that will allow you to find the equation of the parabola. Write the system in the space provided.

The three system of equations are 9a + 3b + c = 8, 75a + 15b + 3c = 20, and 36a + 6b + c = 5.

<h3>What is a solution to a system of equations? (SOLUTION GRAPHICALLY)</h3>

For a solution to be the solution to a system, it must satisfy all the equations of that system, and like all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at a single point(as we need a common point, which is going to be the intersection of course)(this can be one or many, or sometimes none).

The general equation of parabola is given as,

y = ax² + bx + c

The first point is (3,8), therefore, we can write,

8 = a(3)² + b(3) + c

9a + 3b + c = 8

The second point is (5, 20/3), therefore, we can write,

20/3 = a(5)² + b(5) + c

75a + 15b + 3c = 20

The third point is (6, 5), therefore, we can write,

5 = a(6)² + b(6) + c

36a + 6b + c = 5

Hence, the three system of equations are 9a + 3b + c = 8, 75a + 15b + 3c = 20, and 36a + 6b + c = 5.

over the week the daily low temputures in degrees Fahrenheit have been -4, 6.2, 18 1/2, -5.9, 21, -1/4, and 1.75. list these num
8_murik_8 [283]

over the week the daily low temputures in degrees Fahrenheit have been -4, 6.2, 18 1/2, -5.9, 21, -1/4, and 1.75. list these numbers in order from least to greatest​

we have that

1/2=0.5

1/4=0.25

so

order from least to greatest​

<h2>-5.9,-4,-1/4,1/2,1.75,6.2,18,21</h2>
