It's a 4th degree polynomial since the largest degree (exponent) is 4
Answer:
The ratios are both identical. (4 over 5 and 4 over 5)
Step-by-step explanation:
Th picture below represent the image you are referring.
sin x = opposite / hypotenuse
opposite side = 4
hypotenuse = 5
sin x° = 4/5
cos y° = adjacent/hypotenuse
adjacent = 4
hypotenuse = 5
cos y° = 4/5
The ratios are both identical (4 over 5 and 4 over 5)
Quick answer
Any irrational number. I can't think of any exception to this statement.
sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.
-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational
2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.
1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.
Conclusion
There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2
First the equation would look like this:
7n = 5n - 3
7n - 5n = 5n - 5n - 3 -Subtract 5n from both sides. Which gives you...
2n = -3
2n/2 = -3/2 -Divide both sides by 2
n = -1.5
Hope this helps!
Answer:
Area
Step-by-step explanation:
Using the perimeter will only give you the measurements of the outside. But since you need to fill the harbor with water, you need the depth as well.
