Step-by-step explanation:
-(-1) is 1 because if you multiply by a negative number becomes positive
so
it is 1 unit to the right of 0

Answer:
Step-by-step explanation:
We are given that
We have to find the value of
To find the value of we will use table of sin
From sin table
We get
=0.587785
We have to round off the answer to four decimal places
Therefore,
Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)
= 8, -2
