<span>A ball is thrown at a 30 degree angle above the horizontal with a speed of 10 ft/s. After 0.50s the horizontal component of it's velocity will be the same. In a projectile motion the horizontal component of the velocity is said to be constant. Therefore, it will be equal to the initial velocity.</span>
Answer:
50
Step-by-step explanation:
Figure out all variables
100/(2x5= 10)-9+(3x.33=1)
100/10-9+1
100/2
50
Answer: it will take 40 rides to break even.
Step-by-step explanation:
Profit = Revenue - total cost
At the point of break even, there is no profit. It means that
revenue = total cost
The cost c (in dollars) for the fuel and maintenance of a go-cart is given by
c = 10x + 1200
where x is the number of rides. It costs $40 per ride. This means that the revenue gotten from x rides is 40x.
In order to break even, it means that
40x = 10x + 1200
40x - 10x = 1200
30x = 1200
x = 1200/30
x = 40
Answer:
60°
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the 2 interior opposite angles.
let the other interior angle be x, the
x + 50 = 110 ( subtract 50 from both sides )
x = 60
Thus the other interior opposite angle is 60°
