Answer:
see below
Step-by-step explanation:
A discriminant value of zero means there is exactly one x-intercept. The graph below has that characteristic.
_____
<em>Comment on discriminant</em>
discriminant > 0, two (2) x-intercepts (first 2 graphs)
discriminant < 0, no (0) x-intercepts (third graph)
Answer:
x = 
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin60° = 
sin60° = 
= 
= ( cross- multiply )
x × 
= 8 ( divide both sides by )
x = 
× 
( rationalising the denominator )
x =
<span>2L+2W=30
L=2W
2(2W)+2W=30
4W+2W=30
6W=30
W=30/6
</span><span>
W=5 width
L=2*5=10 length
PROOF:
2*5+2*10=30
30=30
5*10=50 area
So your answer is 50
