N(s) = 36
n(F) = 18
P(E) = 18 / 36
= 1/2.
Good morning Brainiac
m=n-2
m+4n=8
We need to solve m=n-2 for m
Substitute n-2 for m in m+4n=8
m+4n=8
n-2+4n=8
5n-2=8
Add 2
5n-2+2=8+2
5n=10
Now divide both sides by 5 so we can find the value for n
5n/5=10/5
n=2
Now substitute 2 for n in m=n-2
m=n-2
m=2-2
m=0
Answer : C
(0,2)
I hope that's help:0
Answer:
3. A
4. B
5. C
6. A
7. D
Step-by-step explanation:
It is easy you just need to be paying attention in class then you will get it. I used to go on Brainly for people to do my homework but it is no worth it. you need to try it on your own. When you turn it in and you get it all correct and you get an A. You are just checking yourself.
Distance=speed*time
distance traveled by plane A after 40 minutes:
distance=570×40/60=380 miles
Distance traveled by B after 40 minutes
distance=20/60×585=195 miles
Thus the distance between them will be given using cosine law:
c^2=a^2+b^2-2ab Cos C
thus we shall have:
c^2=380^2+195^2-2*380*195*cos22
c^2=45016.35275
c=212.171 miles
Thus the distance between them after 40 minutes is 212.171 miles
