If you would like to find the discriminant of the quadratic equation 0 = 2x^2 + 3x - 5, you can do this using the following steps:

<span>0 = 2x^2 + 3x - 5
0 = ax^2 + bx + c
a = 2, b = 3, c = - 5

</span>D = b^2 - 4 * a * c = 3^2 - 4 * 2 * (-5) = 9 + 40 = 49

The correct result would be 49.

Which ratio is equivalent to 3:18?<br> A 6:21<br> B 5:20<br> ( 7:42<br> D 12:2
anzhelika [568]
Answer is C. 7:42
Because the numbers from the ratio 3:18 , 18/3 is 6
And from the ratio 7:42, 42/7 is also 6
Because the difference in the ratios are the same, the ratios are equivalent

Another way is that 3:18 can be rewritten as 3/18 which is simplified to 1/6. 7:42 = 7/42 which also equals 1/6.

Both ratios simplified equal 1:6.
None of the other answers simplify to this but C.

Calculate the amount and compound interest on
mart [117]

Answer:

Below in bold.

Step-by-step explanation:

i) Amount = 15000(1 + 0.10)^2 = 18,150.

Interest = 3,150.

ii) Amount = 15620(1 + 0.08/2)^(3/2*2)

= 15620(1 + 0.04)^3

= 17,570.38.

Interest =1,950.38.

iii) Amount = 100000(1 + 0.04/4)^(3)

= 100000(1 + 0.01)^3

= 103,030.1

Interest = 3030.1.
