Answer:
C
Step-by-step explanation:
times = 3 and times x = x
So that means that answer is 3+x which is C
Answer:
r = 5.696 and θ = 157.17°.
Step-by-step explanation:
the point is (-5.25,-2.21). The distance from the point to the origin is calculated with the formula
r = 5.696 m.
I drew the point and the distances in the plane. to find te angle we can use the sin formula:
sin(θ) =
θ = .
within the range of -180° and 180° the angle will be θ = 180-22.83 = -157.17°
Answer:
x = 2 and x = -2
Step-by-step explanation:
The quadratic formula of a quadratic of the form ax² + bx + c is:
x = or x =
Here, our equation is: 3x² - 18 = -6. Let's move all the terms to one side:
3x² - 12 = 0
a = 3 and c = -12. Notice that since there's no x term, b = 0.
Plug these into the quadratic formula:
x =
or
x =
So, x = 2 and x = -2.
