Answer:
Step-by-step explanation:
hello :
2x² + 25 = -x² + 10x
2x²+x²-10x+25 =0
3x²-10x+25=0
∆ = b²- 4ac a=3 and b=-10 and c=25
∆ = (-10)²- 4(3)(25)=100 -300 = -200< 0
two complex solutions
2/3 cup + 2/3 cup = 1 1/3 cups
1 1/3 cups - 1/4 = 1 1/8 cups
There will be 1 1/8 cups left after the broth has been boiled.
Answer:
D
Step-by-step explanation:
When the function or the coefficient in this case 1/4x^2 is positive it means it's opening up like a u, meaning all the values will be bigger than the C term or -5 in this case.

Step-by-step explanation:
<u>Funciones Trigonométricas</u>
La identidad principal en trigonometría es:
Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.
Dado que Sen A = 4/5, calculamos el coseno:
Sustituyendo:
Tomando raíz cuadrada:
La tangente se define como:
