Answer:
z = -9.538546756+ 15.26486573i
Step-by-step explanation:
z = |z| cos theta + |z| i sin theta
We know |z| and theta
z = 18 cos 122 +18i sin 122
z = -9.538546756+ 15.26486573i

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

So, in conclusion Harry did earn $6 in interest for every $100
division problem
In a division problem, the number being divided into pieces is the dividend. The number by which the dividend is divided is called the divisor. And the answer to the division problem is the quotient.
Formula for trapezoid
A=h*(b1+b2)/2,
b1 an db2 are the two lengths of the sides
152 = 16*(b1+6)/2 = 8*(b1+6)=8*b1+48--> 8*b1=104, b1 = 104/8=13
A = 16*(6+13)/2=16*9.5=152
