(3+4i)*4 = 3*4+4i*4 = 12+16i
The complex number 12+16i is in the form a+bi where a = 12 and b = 16
m = modulus
m = distance from (0,0) to (a,b)
m = sqrt(a^2+b^2)
m = sqrt(12^2+16^2)
m = sqrt(144+256)
m = sqrt(400)
m = 20
Answer: 20
B)1,131.20 would be the answer. 1010x0.14=141.4x8=B
Standard form: x-y = -3
x & y have to be whole numbers
x has to be positive
Answer:
x= 0.4, or x = 2/5
Step-by-step explanation:
To find x you have to replace f(x) with 0 and solve for x
Hope this helps:)
The attached image represents the foci of the hyperbola
<h3>How to determine the foci?</h3>
The equation of the hyperbola is given as:

Rewrite as:

A hyperbola is represented as:

This means that:
h = 0
k = 0
b = 25
a = 60
Next, calculate c the distance from the center to the focus using:

This gives

Evaluate

This means that:
Foci = (0, -√2975) and (0, √2975)
