Answer:
7 and 1
Step-by-step explanation:
√50 is the sum of the square of two legs
The answer is likely to be 7 and 1 (because 7^2 + 1^1 = 50)
This is like the equation of a line where y is the area, x is the time, and 8.5% is your slope. So you have y=0.085x+b (reason why I switched 8.5% into 0.085 is because that is how you write a percent as a decimal).So now you need to find what b is. So you know orignally the area is 2400km^2 at x=0 years (this is what it is initially).If you plug those numbers in you have:2400=0.085(0)+bThen after solving for b, you can write your equation as:y=0.085x+(whatever you found b to be)Then plug 13 in for x and you have your answer. y=-.085(13)+2400
Answer:
1. True
2. True
3. y = -1
4. False
Step-by-step explanation:
1 -------------------------
sin(-90) = -1
sin(270) = -1
True
2 --------------------------
y = cos(-90)
y = 0
True
3 -------------------------
y = tan(-45)
y = -1
-1
4 ---------------------------
tan(90) cannot be calculated
False
Combine like terms
a^2-4a^2=-3a^2
7a^3+11a^3=18a^3
Then put them back together from greatest exponent to smallest exponent
18^3-3a^2-a
