Answer:
1) v= 280 in^3 sa= 262 in^2
2) v= 80 in^3 sa= 120 in^2
3) v= 36 in^3 sa= 72 in^2
4) v= 240 in^3 sa= 252 in^2
Answer:
Step-by-step explanation:
B=2h(a+b) #the numerator goes to the other side, the denominator then just makes it B
B/2h=a+b
2h=a+b/B
2h-a=b/B
2h-a=b(1) #factorise

Answer: V = (10.4 mph, 38.6 mph)
Step-by-step explanation:
The velocity is written as (vx, vy)
where vx is the component of the velocity in the x-axis and vy is the component of the velocity in the y-axis.
In usual notation, the angles are measured counterclockwise from the positive x-axis.
We know that the angle is 75°, this means that the velocity in the x-axis will be equal to the total velocity of the bird projected in the x-axis (suppose a triangle rectangle, where the velocity is the hypotenuse, the x component is a cathetus and the y component is other cathetus)
vx = 40mph*cos(75°) = 10.4 mph
vy = 40mph*sin(75°) = 38.6mph
Then the vector of velocity is V = (10.4 mph, 38.6 mph)
