Answer:
-250
Step-by-step explanation:
Each thing is multiplied by -5.
Condense z₁ and z₂ into their exponential forms:
z₁ = 3 (cos(π/4) + i sin(π/4)) = 3 exp(i π/4)
z₂ = 7 (cos(3π/8) + i sin(3π/8)) = 7 exp(i 3π/8)
Then the quotient of z₁ and z₂ is
z₁ / z₂ = 3/7 exp(i (π/4 - 3π/8)) = 3/7 exp(-i π/8)
and in trigonometric form,
z₁ / z₂ = 3/7 (cos(-π/8) + i sin(-π/8))) … … … D
Well, the formula for a triangle is base times height times 1/2. In this case it would be 21x30. That equals 630. Then, you divide 630 by 2 which is 315. Your answer would be 315 squared.

Answer:
21
Step-by-step explanation:
The expression Jackie came up with is:
0.75m = 15.75.
To get the value of m, we divide both sides by 0.75
0.75m = 15.75.
0.75m/0.75 = 15.75/0.75
m = 1575/75
= 21
