Answer:
-2
Step-by-step explanation:
First remove parenthesis. Next collect the like terms. Next move terms. Next collect the like terms and calculate. Divide both sides by 8. Your answer is -2
y=a.(X-x1)(X-x2)
x1 and x2 are x-intercepts
x1=-3
x2=1
other points: (-1,8) and (0,5)
y=a.(x+3).(x-1)
a=-2
f(x)= -2.(x+3)(x-1)
Answer:
a = 36.37 cm
c = 18.19 cm
Step-by-step explanation:
to find a, use tan
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 1.732
⇒ 1.732 = 
multiply 21 on both sides
⇒ 1.732 x 21 =
x 21
⇒ 36.37 = a
to find c, use sine
⇒ sine = 
⇒ sine 60 = 
sine of 60 is 0.866
⇒ 0.866 = 
muliply 21 on both sides
⇒ 0.866 x 21 =
x 21
⇒ 18.19 = c
