The x is the variable so you have to find what the equation equals in order too find out what variable x is. 2 x7+2 = 16. So now x = 16
Answer:
0.5j+19
Step-by-step explanation:
Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
Answer:
1. 
2. 
Step-by-step explanation:
1. 8 = 4 * 2; 10 = 5 * 2; 18 = 9 * 2....
2. 4 = 1 * 3 + 1; 7 = 2 * 3 + 1; 10 = 3 * 3 + 1....
130.95 rounded to the nearest tenths place is 131.0
A five or above means you round up.
