The two roots a + sqrt b and a - sqrt b are called conjugate radicals.
<u>Solution:</u>
Given that the two roots a + sqrt b and a - sqrt b are called ______ radicals.
Now let us write the each of the given two radicals in mathematical form.
So, first radical ⇒ a + sqrt b ⇒ 
[ since sqrt means square root]
Now second radical ⇒ a - sqrt b ⇒ 
We have to find the relation between 
Now, if observe is conjugate of 
[ where radical is eliminated]
Hence, the two roots a +sqrt b and a- sqrt b are called conjugate radicals

Step-by-step explanation:
( 50 / 5² )² ÷ 4 (by PEDMAS, do the terms inside the parentheses first)
= [ (5 · 10) / (5 · 5) ]² ÷ 4 (the 5's cancel out in the numerator and denominator)
= [ (10) / (5) ]² ÷ 4
= [ 2 ] ² ÷ 4
= 4 ÷ 4
= 1
Hope this helps
Answer:
Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle.
Explanation:
A line intersecting a circle in two places is referred to as a secant. The portion of the secant contained within the circle is called a chord.
This means that both chords and secants intersect the perimeter of a circle twice, chords are entirely inside the circle, and secants extend through a circle to the outside.

Answer:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
Step-by-step explanation:
Given that a random sample of 311 medical doctors showed that 135 had a solo practice.
Sample proportion = 0.43
Std error of sample proportion = 
Margin of error 90% 
Margin of error in percent = 4.6%
Hence correction option is:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
