Answer: e. 2h + 3 = 10; h = 3.5h
Explanation:
Jane can run 2 miles per hour. (2h)
He need to run 10 miles in total and has done 3 so far. (+ 3 = 10)
The equation can be written:
2h + 3 = 10
2h = 7
h = 7/2 = 3.5
Answer:
cos 4u = co^s2 2u - sin^2 2u
Step-by-step explanation:
cos 4u = co^s2 2u - sin^2 2u
Let 4u = 2x
cos 2x = cos^2 x - sin^ 2 x
cos (x+x) = cos^2 x - sin^ 2 x
Using cos(x+y) = cos(x)cos(y) -sin(x)sin(y)
cos(x) cos(x)- sin(x) sin (x)= cos^2 x - sin^ 2 x
cos^2 (x) -sin^2 (x) =cos^2 x - sin^ 2 x
Since this is true
cos 2x = cos^2 x - sin^ 2 x
This is true
Substituting 4u back for 2x
cos 4u = co^s2 2u - sin^2 2u
This is true

Answer:
B; 3/14
Step-by-step explanation:
Answer:
4/5
Step-by-step explanation:
points: (10,5), (5,1)
(y2-y1)/(x2-x1)
= (5-1)/(10-5)
= 4/5
