Answer:
25
Step-by-step explanation:
Given is -
The variables y and x have a proportional relationship, and y = 5 when x = 4.

As we have to find the value of x when y= 8 so putting y = 8 in the above relationship, we get :



Hence, the answer is 6.4
Answer:
A series can be represented in a compact form, called summation or sigma notation. The Greek capital letter, ∑ , is used to represent the sum. The series 4+8+12+16+20+24 can be expressed as 6∑n=14n . The expression is read as the sum of 4n as n goes from 1 to 6 .

Answer:
2 imaginary; 2 real
Step-by-step explanation:
You can factor it as ...
f(x) = (x^2 -16)(x^2 +1) . . . . . . . . . x^2-16 is the difference of squares
= (x -4)(x +4)(x^2 +1)
The two linear factors have real zeros; the quadratic factor has two imaginary zeros. There are 2 imaginary and 2 real zeros.
