For this case we have the following equation:
An equivalent way to write this equation is to multiply both sides of the equation by a scalar.
When multiplying both sides of the equation by 100 we have:
By doing distributive property we have:
Answer:
An equation that is equivalent is:
9514 1404 393
Answer:
3.0
Step-by-step explanation:
The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values
x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3
x ≈ 3.0
Answer:
he made $50 in profits
Step-by-step explanation:
$5 x 90 subs = $450
$450 - $400 = 50
Answer:
Step-by-step explanation:
+ 3 = -z
= -z - 3
Square both sides , we have
2z =
2z = + 6z + 9
re arranging the equation , we have
+ 6z - 2z + 9 = 0
+ 4z + 9 = 0
This will give a complex roots , solving by quadratic formula
z = -2 + i , -2 - i
