Answer:
the function has two distinct real roots.
Step-by-step explanation:
D=b²-4ac
D<0 No real roots
D=0 One real root
D>0 Two distinct real root.
(-5)²-4*1*-3
25+12
37
Since D is > than 0, the function has two distinct real roots.
Answer:
8
Step-by-step explanation:
100 = x^2 + AC^2
17^2 = AC^2 + (21 - x)^2
289 = AC^2 + 21^2 + x^2 - 2*21*x
289 =<u> AC^2</u> + 441 +<u> x^2</u> - 42x
from 1st equation AC^2 + x^2 = 100
289 = 441 + 100 - 42x
289 = 541 - 42x
42x = 541 - 289 = 252
x = 252/42 = 6
so AC^2 = 100 - 6^2 = 100 - 36 = 64
AC = 8
There are one-hundred $1 in $100.
Responder:
x = 42,4
Explicación paso a paso:
Podemos encontrar el valor de x ya que no se nos dice qué buscar
La suma de dos ángulos suplementarios es 180 grados, por lo tanto;
2x - 14 + 3x - 18 = 180
2x + 3x - 32 = 180
5 veces = 180 + 32
5 veces = 212
x = 212/5
x = 42,4
Por tanto, el valor de x es 42,4
