I don't know how to do a cubed root, and i was wondering if anyone knew the buttons to push or anything, and the manual is too confusing. Help?

A ball of mass 0:4 kg, initially at rest, is
kicked directly toward a fence from a point
20 m away, as shown below.
The velocity of the ball as it leaves the
kicker's foot is 17 m=s at angle of 51 ± above
the horizontal. The top of the fence is 7 m
high. The kicker's foot is in contact with the
ball for 0:04 s. The ball hits nothing while in
°ight and air resistance is negligible.
The acceleration due to gravity is 9:8 m=s2.


What is the vertical component of the velocity
when the ball reaches the plane of the fence?
Answer in units of m=s.

These need to be simplified . I keep getting the wrong answer when i do it . can you please show work ! thanks so much .

1. 3x^2-2[x-(3-2x)] = 3(x-2)^2

2. 7-[x+(3-2x)] = [-(2x-4)-18]+x

3. 4[5y-4(y-1)] = 3[4(y+1)-7y]

4. 5-3(x-3) = 3-2x

5. 4y-(5y-1) = 5

Find the quadratic polynomial g(x)=ax^2+bx+c which best fits the function f(x)+9^x @ x=0 in the sense that f(0)=g(0) and f'(0)=g'(0) and f''(0)=g''(0)

g(x)=?

[b]1. Two boats start out 800 miles apart with boat A directly to the west of boat B. At the same time both boats start moving with boat A travelling to the east at 40mph while boat B travels north at 20mph. Determine if the distance between the boats is increasing, decreasing, or not changing after the following travel times: (a) 7 hours (b) 16 hours (c) 25 hours [/b]



[b]2. I attempted to break apart their distances travelled by using component vector analysis. The distance between the two boats is the hypotenuse of whatever triangle they produce on the graph at a certain time. We want to find d'.[/b]



[b]3. d'=? I park boat A at origin, therefore its cartesian coordinates are (0, 0), so boat B must be at (0, 800)

For part (a) I use vector components: A in x-direction: 400(7)=280 x-direction
A is (280, 0) B is (800, 140)
Base distance is 800-280=520 Height is just 140, how do I proceed to find h' ? Similar triangle don't work bcuz boats have diff. rates.

Which of the following is the equation of a circle with center (-5, 2) and radius of 6?

(x + 5)2 + (y - 2)2 = 6

(x - 5)2 + (y + 2)2 = 6

(x + 5)2 + (y - 2)2 = 36

(x - 5)2 + (y + 2)2 = 36
