The way you'd set it up would be sin55º/12=sinB/14 (you could also flip the equation so that 12/sin55º=14/sinB, you'll get the same answer either way). Multiply out so that its 14•sin55º=12•sinB, or 11.47=12•sinB. Divide both sides by 12 so that it looks like .96=sinB, then take arcsine of both sides (arcsin= x=sin^-1 theta+360n or x=180- (sin^-1 theta)+360n), which should give you about 72.88º and 107.12º.
Answer:
y = 0,5 x + (-3)
Step-by-step explanation:
We can see from the graph that when y = -3, the line crosses y axis, therefore
y = ? x + (-3)
We can also spot that when x = 6, y = 0
// now mark ? sign as a variable k and put the given x and y values into the previous expression
y = k * x - 3
0 = k * 6 - 3
k * 6 = 3
k = 3/6
k = 0,5
Respuesta:
3395 L
Explicación paso a paso:
Dado que el tubo contiene 35 L de agua por metro.
Esto significa que el volumen por metro del tubo es de 35 litros.
Longitud total del tubo = 97 metros
Volumen de agua en toda la longitud del tubo:
Volumen por metro * 97
35 L * 97
= 3395 litros
Por lo tanto, peso cuando está lleno = 3395 L
Answer:
x>1
Step-by-step explanation:
x + 18 > 19
Subtract 18 from each side
x + 18-18 > 19-18
x>1
