dedylja [7]

The value of p+q = 403,For the given complex number a+bi and b^{2} =\frac{p}{q}

where p and q are co-primes

F(z)= (a+ib)z⇒this is equidistant from "0" and "z"

Given  modulus of complex number (a+ib) = 10 ; b^{2} =\frac{p}{q} p and q ∈Z

G.C.D of ( p and q)=1

(a+ib)z equidistant from "0" and "z"

&\Rightarrow|(a+i b) z-z|=|(a+i b) \bar{z}-0|\\&|z(a+i b-1)|=|(a+i b) \bar{z}|\\&[\bar{z}||(a-1)+i b|=| z|(a+i b)|\\&|a-1+i b|=|a+i b|\\&\sqrt{(a-1)^2+b^2}=\sqrt{a^2+b^2}\\&|a+i b|=10 \quad a^2+1-2 a+b^2=x^2+b^2\\&\sqrt{a^2+b^2}=10\\&a=1 / 2\\&a^2+b^2=100\\&b^2=100-\frac{1}{4}\\

b^{2} =\frac{399}{4}

p = 399 and q= 4

p+q= 399+4

p+q=403

Hence the value of p+q = 403

Complete question:A function f is defined on the complex number by f (z) = (a + bi)z, where 'a' and 'b' are positive numbers. This function has the property that the image of each point in the complex plane is equidistant from that point and the origin. Given that |a+bi|=8 and thatb^{2} =\frac{p}{q}  where p and q are coprime. Find the value of (p+q)

hettie is stacking paper cups .each stack of 15 cups is 6 inches high. what is the total heightvof 10 stacks of cups ?
Maslowich
60 inches is the answer.

In this case the amount of cups do not matter only the height because that's what it's asking for.

If each stack is 6 inches we would have to multiply that by 10 because there are 10 stacks.

6 x 10 = 60 inches tall
