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
Answer: 42°
Step-by-step explanation:
Complimentary angles are angles sum up to make 90°
From the ratio given 7:8,
Add the ratios together and find the smaller angle as follows
7 + 8 = 15
Therefore,
⁷/₁₅ x 90 = 42°
The smaller angle is 42°
Answer:
They have the same slope.
Step-by-step explanation:
Answer:
The percentage decrease in the depth is 45%
Step-by-step explanation:
January, lake depth = 1086 feet
august, lake depth = 597.3 feet
The decrease in depth = 1086 - 597.3
= 488.7 feet
Percentage decrease = decrease over January lake depth multiply by 100%
% decrease = (488.7/1086)*100%
=0.45*100%
= 45%
