area = 1/2 *b*h
1/2 * 15 * 8 = 60 square units
First write both vectors in terms of their horizontal and vertical components.
G = (40.3 m)(cos(-35.0º) x + sin(-35.0º) y)
G = (33.0 x - 23.1 y) m
(where x and y are the unit vectors that point in the positive horizontal and vertical directions, respectively)
H = (63.3 m)(cos 270º x + sin 270º y)
H = (-63.3 y) m
Then the vector sum is
G + H = (33.0 x - 86.4 y) m
which has a magnitude of
|| G + H || = √[33.0^2 + (-86.4)^2] = 92.5 m
Answer:
1,610 miles
Step-by-step explanation:
If you do 460/20 you get the gas mileage. The gas mileage is 23. If you do 23*70 you get 1610 miles out of 70 gallons of gas. (Double-check to make sure I'm correct)
Break the expression into two groups, then if you factor out what you need to do, then factor out the common term, you'll end up with ( 3x - 11 ) ( x - 10 )
Answer:
p = 2a + 2b
Step-by-step explanation:
The perimeter p is the sum of the 4 sides , then
p = a + a + b + b = 2a + 2b
