Answer:
Step-by-step explanation:
put x=0
0+4=a(0+2)(0-4)+0+0
-8a=4
a=-4/8=-1/2
put x+2=0 or x=-2
2(-2)+4=0+b(-2)(-2-4)+0
12b=0
b=0
put x-4=0 or x=4
2(4)+4=0+0+c(4)(4+2)
24c=12
c=12/24=1/2
Answer:
Step-by-step explanation:
To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that
Substituting a,b,c and d for 8,15,2 and 13 we obtain that
Answer:
sin θ =
Step-by-step explanation:
Given that,
cos θ =
From the trigonometric functions,
cos θ =
⇒ adjacent = , and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
=
+
=
+
9 = 3 +
= 9 - 3
= 6
x =
Thus, opposite side =
So that,
sin θ =
=
Therefore,
sin θ =
