Answer:

Step-by-step explanation:

I wrote an excel macro that listed all of the combinations of these 6 numbers in a string, with the x and = symbols mixed in every possible way. (The first combination was “1*2=4568” and the last one was “8654=2*1”) I then had the macro evaluate the equations and find the ones that evaluated to true. Out of the 18,000 combinations of numbers and math symbols, only 8 of them evaluated to true. The true combinations are…………..

416=52*8

416=8*52

512=64*8

512=8*64

52*8=416

64*8=512

8*52=416

8*64=512

(Note that there are only 2 distinct combinations that work. The macro found all the ways that you can express those 2.)

If the discriminant, b^2-4ac is ___, a quadratic will have two real roots, two points of intersection with the x-axis.
den301095 [7]

If the discriminant, b² - 4ac is<u> positive</u>

<h3>How to complete the statement?</h3>

From the question, we have the following equation of discriminant

The discriminant (d) is calculated as

d = b² - 4ac

The solutions of a quadratic equation are dependent on the following conditions

  • If d = 0, the quadratic equation has 1 real solution
  • If d < 0, the quadratic equation has imaginary solutions
  • If d > 0, the quadratic equation has 2 different real solutions

This means that "d > 0, the quadratic equation has 2 different real solutions" implies that the discriminant is positive

Hence, the complete statement is (b) positive

Answer: 320 g

Step-by-step explanation:

We can set up a ratio.

Let the amount of oats equal to x.

18/240 = 24/x

We can now cross multiply.

18x = 5760.

x = 320 g
