Opposite of the right angle
Step-by-step explanation:
or,[(√-x-1)+(√x+9)]^2=4^2
or,(√-x-1)^2+2√(-x-1)(x+9)+(√x+9)^2=16
or,-x-1+2√-x^2-10x-9 +x+9=16
or,2√-x^2-10x-9=8
or,√-x^2-10x-9=4
squaring on both sides
or,-x^2-10x-9=16
or,-x^2-10x=25
or,-x(x+10)=25
Either,
x=-25 or, x=15.
Answer:
A. QII.
Step-by-step explanation:
The tan < 0 in Quadrants 2 and 3.
The csc > 0 in Quadrants 1 and 2.
I am pretty sure the answer is the first box on the top right corner. Because vertical angles means they make an "X" shape, and that was the only one that did.
Answer:
About 158 times
Step-by-step explanation:
Represent the rate of human heart with H and sparrow's heart with S


Required
Determine how many times faster is S than H
To do this, we simply divide S by H i.e.



--- approximated
<em>Hence, the sparrow's heart beats about 158 times faster than the human hearts</em>
