Let z = a + b.
a. let uz be represented by the vector in the direction of z with length 1. how can you find uz? what is the
value of uz?
b. let uw be the complex number that when multiplied by uz, the product is 1. what is the value of uw?
c. what number could we multiply z by to get a product of 1?

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
