Answer:a
Step-by-step explanation:
Answer:
<em>The absolute square of a complex number is calculated by multiplying it by its complex conjugate. This give the magnitude squared of the complex number. The absolute square is </em><em>A</em><em>l</em><em>w</em><em>a</em><em>y</em><em>s</em><em> </em><em>R</em><em>e</em><em>a</em><em>l</em><em>. We will use complex exponentials all the time.</em>
∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)
The variable is b, the coefinet is 1/3
remember
ab-ac=a(b-c)
1/3b-1/3=1/3(b-1)
there, factored
Answer:
4 2/ 7
Step-by-step explanation:
using a = a/1, convert the expression into fraction
5/1 x 6/7 to multiply the fractions, multiply the numerators and denominators separately
5x6/1x7 = 30/7 alternative form 4 2/7, 4.285714
