yes, there are infinitety many polynomial that have exactly one real root just like your example, to determine the real root first let the real root is a, and the complex roots are b±ic the polynomial satisfy

-9x³ + 19x² + 17 = -(x - a)(x - b - ic)(x - b + ic)

9x³ - 19x² - 17 = (x - a)(x - b - ic)(x - b + ic)

Listen Rachel babysat three children for five hours if they were paid $2.50 per hour for each child and divided their earnings e
lina2011 [118]

Answer: Each girl will receive $18.75.

Step-by-step explanation:

Given: Two girls babysat three children for five hours.

Hourly pay for each child = $2.50

Payment for 5 hours per child = 5\times\$2.50=\$12.5

Payment to 3 children for 5 hours = 3\times \$12.5=\$37.5

So, the amount received by each girl  = \dfrac{\text{Payment to 3 children for 5 hours}}{2}

=\dfrac{37.5}{2}=\$18.75

Hence, each girl will receive $18.75.

The value of a professional basketball player's autograph rose 30% in the last year. It is now worth $273.00. What was it worth
serg [7]
$210
because if it rose 30%, it's now 130% of what is used to be
or (what it used to be) ×1.3
so do the reverse and divide the new cost by 1.3
so 273÷1.3 which is 210
