The answer is 7√3 and I'll tell you why

So the first step is to break down these big numbers to find a commen number like this:

√75= 5√3

√12= 2√3

Next you will just simply add the similar elements together:

5√3 + 2√3

5+2= 7

and so 7√3 is the correct answer

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 that $b^{2} =\frac{p}{q}$ where p and q are coprime. Find the value of (p+q)

4. Elena noticed that, nine years ago, her cousin Katie was twice as old as Elena was then,

kakasveta [241]

Answer:

k - 2e + 9 = 0

k - e - 4 = 0

Step-by-step explanation:

Given that Elena is currently e years old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.

So, k - 9 = 2(e - 9)

⇒ k - 2e + 9 = 0 .............. (1)

And, in four years, Elena will be as old as Katie is now.

So, k = e + 4

⇒ k - e - 4 = 0 ............... (2)

Therefore, the equations (1) and (2) matches the conditions. (Answer)
