The solutions are;
and 
These are the x-intercepts of the graph of the function
Answer:
(a) 3
(b) 4
(c) 3
Step-by-step explanation:
To find the number of significant figure, ignore all zeros on the left and count the remaing digits.
(a) ignore 0.0, so 590 is 3 s. f.
(b) no zeros to the left, so 4 s. f.
(c) ignore 0.00, so 122 is 3 s. f.
1/ 0.6 = x / 250..1 dollar to 0.6 euros = x dollars to 250 euros
cross multiply
(0.6)(x) = (250)(1)
0.6x = 250
x = 250/0.6
x = 416.67 american dollars

Answer: Choice B) 3:1</h3>
=============================================================
Explanation:
Consider a very small town of only 4 people.
If 1 person bikes to work, then 1/4 = 0.25 = 25% of the population commutes by bicycle. We see that the remaining 4-1 = 3 people don't travel by bike.
The odds against selecting someone who uses their bike to get to work is 3:1 which is why the answer is choice B
We list the number of people we don't want first, and then the number of people we do want (those who use a bike). A colon separates the two values to form the odds ratio.
We can say "3:1" as "3 to 1". It means we're 3 times more likely to select someone we don't want vs someone we do want. The odds are against the bike person which is why the value we don't want is listed first.
In contrast, if your teacher asked "what are the odds in favor of selecting someone who commutes by bicycle?" then the answer would be 1:3. We simply swap the positions of what we set up earlier.
Answer:
Area of ellipse is ≈ 77.78 
Step-by-step explanation:
Given the dimension of ellipse
a = 4.5 m
b = 5.5 m
Now, Area of ellipse = 
= 
= 
= 77.78
Hence Area of ellipse will be 77.78
