Answer:
x = 1, -5.56
Step-by-step explanation:
x^2 = -7x - 8
shift -7x and -8 to the other side . Remember when u shift minus changes into plus.
x^2 + 7x + 8 = 0
using quadratic equation formula
in quadratic equation one value comes positive and other comes in negative
a = 1 , b = 7 and c = 8
taking positive sign
x = (-b + 
) /2*a
x = (-7 + 
) /2*1
x = (-7 + 
) /2
x = (-7 + 
)/ 2
x = -7 + 9 / 2
x = 2/2
x = 1
taking negative sign
(-b - ) /2*a
x = (-7 - ) /2*1
x = (-7 - 
) /2
x = -7 - 
/ 2
x = -7 - 4.12 / 2
x = -11.12/2
x = -5.56
therefore x = 1 , - 5.56
Answer:
44°
Step-by-step explanation:
From sin rule:
a / sin A = b / sin B = c / Sin C
3.6 / sin b = 5.1 / sin 100
Cross multiply :
5.1 * sinb = 3.6 * sin 100
Sin b = 3.5453079 / 5.1
Sin b = 0.6951584
b = sin^-1(0.6951584)
b = 44.039
b = 44°
Answer:
4.5
Step-by-step explanation:
Mean = (4+5+6+3)/4 = 4.5 bubbles
Answer:
It's 15°
Step-by-step explanation:
BC+60°+85°+200° =360°
BC+345°=360°
BC=360°-345°
Bc=15°
So if the combined revenues were $51 billion. Then it would be best to divide that between the two companies as a starting point. Each company would have $25.5 billion if they were split 50-50. Since PepsiCo has 9 billion more than Coca-Cola. Simply take PepsiCo's value and add $9 billion to it, which would be $34.5 billion. Finally, take $51 billion, subtract it $34.5 billion, which is PepsiCo's value to get Coca-Cola's value, which is 16.5 billion for me.
