I think it's 108/11.. Pretty sure of it
Well the X intercept is a coordinate point where there is a unique value to X coordinate, other than 0. Since the graph touches the X axis to the left of the graph, the X intercept would be negative. More specifically it would be (-3,0).
Answer:
0.35*4=1.40
Step-by-step explanation:
Think of doing 35*4 but dividing the result by 100, or 2 decimal places to the left:
35*4 = 35*2*2 = 70*2 = 140
140/100 = 1.40
So, 0.35*4=1.40

Answer:
-625
Step-by-step explanation:
The magnitude gets raised to the power, and the angle gets multiplied by the power:
5(cis7pi/4)^4 = (5^4)cis(4·7π/4) = 625cis(7π) = 625cis(π) = -625
