Answer: 12
Step-by-step explanation:
Given:
A = 452
r = √A/3
Step 1: Substitute 452sqf for A
r = √452/3
Step 2: Solve
452 ÷ 3 = 150.66∞
√150.66∞ = 12.27∞
12.27∞ rounded to the nearest integer equal 12
if the roots of the polynomial function are -9 and 7 - i, then the other factor of the polynomial function is x - (7 + i)
<h3>How to determine the other factor?</h3>
The roots of the polynomial function are given as:
-9 and 7 - i
The root is 7 - i is a complex number.
This means that its conjugate must also be a root of the factor.
The conjugate of 7 - i is 7 + i
So, we have:
x = 7 + i
Equate to 0
x - (7 + i) = 0
Hence, the other factor of the function is x - (7 + i)

Answer:
a=11
Step-by-step explanation:
3/a + 5/2a = 1/2
Determine the range
3/a +5/2a = 1/2 , a=0
Write all numerators with common denominators above 2a
11/2a = 1/2
11/2a = 1/2 Simplify the equation using cross-multiplication
22=2a Switch sides of the equation
2a=22 divide both sides of the equation by 2
a=11 is your answer
