5. x2 +5x-4 Discriminate

ikadub [295]

Answer:

D = 41

Step-by-step explanation:

y = ax² + bx + c

The discriminant D = b² - 4ac tells the types of roots the equation has.

If D < 0 , then quadratic equation has no real roots, has two imaginary roots.

If D = 0 , then quadratic equation has one real root.

If D > 0 , then quadratic equation has two distinct real roots.

~~~~~~~~~~~~

x² + 5x - 4

a = 1, b = 5, c = - 4

D = 5² - 4(1)(- 4) = 25 + 16 = 41

erica [24]

Question isn't well formatted, however. From what can be gathered form the question :

Options are given

Answer:

4(1.5 * 16.50) + (1.5 * 9.60)

$113.40

Step-by-step explanation:

Last year:

Cost of full page ad = $16.50

Cost of half page ad = $9.60

50% increase in ad price this year :

Price, this year :

Full page = 1.50 * 16. 50 = $24.75

Half page = 1.50 * $9.60 = $14.4

Expression :

4(1.5 * 16.50) + (1.5 * 9.60)

Cost of a 4 and 1/2 page ad :

Full page = 4 * $24.75 = $99

Half page = 1 * $14.4 = $14.40

Total cost = $(99 + 14.40) = $113.40
