z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
Answer:
A
Step-by-step explanation:
The red function is a transformation. Transformation have the following rules:
- f(x-a) is a units shifted to the right
- f(x+a) is a units shifted to the left
- f(x)+a is a units shifted up
- f(x) -a is a units shifted down
It shifts the red graph 1 unit to the right. This is f(x-1).
Answer:
Angle C = 45°
Step-by-step explanation:
Hello There!
If you didn't know opposite angles are congruent in parallelograms
So ∠A≅∠C and ∠B≅∠D
So if ∠A = 45° then ∠C also equals 45°
Answer:
The jar of chermical contains 66g of Zinc.
Step-by-step explanation:
The ratio of Zinc to Copper is 3 : 13
A jar of the chemical contains 286g of copper.
Let the mass of the Zinc be xg.
13/3 = 286/x
x = 3A286/13= 66g
So the jar of chemical contains 66g of Zinc.
