FinnZ [79.3K]

Answer:

Ebony will win the competition

Step-by-step explanation:

<u>Kiara:</u>

$m=5t,$ where t represents the time in seconds, and m represents the number of math facts completed.

When t = 1, then m = 5

5 math facts per second

<u>Giovanni:</u>

From the table:

20 math facts - in 5 seconds

40 math facts - in 10 seconds

60 math facts - in 15 seconds

4 math facts per second

Ebony:

From the graph

12 math facts in 2 seconds

24 math facts in 4 seconds

36 math facts in 6 seconds

48 math facts in 8 seconds

60 math facts in 10 seconds

6 math facts per second

Area of trapezoid = 1/2 (sum of parallel sides) × (perpendicular distance between them)

DС = 2 + 12 + 2 = 16 in

Area = 1/2 (16 + 12) × 9 = 14 × 9 = 126 in²

Which is the best approximation of the solution shown on the linear-quadratic system graphed below?

Darya [45]

Answer:

The beast approximated solution of the linear-quadratic graph is (-1 , 3)

the second answer

Step-by-step explanation:

* To solve this system of equation accurately

- You must have the equation of the parabola

- You must have the equation of the line

- You will solve them together by substitution method to find

the points of intersection between the parabola and the line

* But here we will try to find the approximated solution

∵ The point if intersection is between -1 and -2 as

x-coordinate nearest to -1

∵ The point if intersection is between 2 and 3 as

y-coordinate nearest to 3

∴ The best solution is (-1 , 3)

* The beast approximated solution of the linear-quadratic graph is (-1 , 3)
