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)
Explain: it’s equals to 20
Y is same as the missing angle, the triangle need to equal to 180 so if you add 20 to 60 it equal to 80
use 180 to subtract to 80 you will get the missing x, x=80
5pm=11
so 3f for every hour
6 hours
3 times 6=18
drops 18
11-18=-6
-6f after 6 hous
Answer:3 0/ (1/3 pi 8^2)
Step-by-step explanation:
the formula for vaume is 1/3pi r^2*h=V
to find the hight you revers it you get 30/ (1/3 pi 8^2)
so you get 30/ (1/3*pi*16)
you then get 30/5.3inf pi
the rusulte is 5.6 pi left in terms of pi
I hope that helps
