A ball is thrown horizontally with a speed of 10 m/s, from the edge of the top of the building of height 19.6m, and later strike

s the ground.
1) For how long was the ball in the air?
2)what is the vertical component of the velocity just before the ball strikes the ground?
3) what is the horizontal component of the velocity just before the ball strikes the ground?
4)how far from the base of the building did the ball strike the ground?
5) what is the speed of the ball just before it strikes the ground?

1) You need to solve t - 19.6=.5(9.8)t^2
2) Then solve fvf^2=2(9.8)(19.6)
3) As it's constant it is<span> still 10m/s
4) You need to </span><span>use the</span> time from part 1 times 10m/s
5) Use Pythagorean theorem with <span>10m/s and vf

I am pretty sure it will help you.</span>

Find an equation of the line through (3,6) and parallel to y = 4x - 7.
FromTheMoon [43]

Answer:

y=4x-6

Step-by-step explanation:

Okay, to do this we must understand what parallel means.

parallel means that that one line will NEVER touch the other. In order for this to happen they must be increasing (or decreasing) by the SAME rate. I.e the slope of your line must be the same as the lin in question thus our equation looks like,

y=4x+c.

Now lets find c.

To do this, plug the point (3,6) into the equation

6=4(3)+C

6=12+C

-6=C

Thus now that we know C, our equaiton is

y=4x-6

4. which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − 8x3 3 6x2 − 6x 5
CaHeK987 [17]
ANSWER

The algebraic expression that is a polynomial with a degree of 2 is
6 {x}^{2}  - 6x + 5



EXPLANATION

The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.


The highest degree of the polynomial is considered the degree of the polynomial.



For first option,
4 {x}^{3}  - 2x + 10
the highest degree is 3.



The second option is,
{x}^{2}  - 8 {x}^{3}  + 3
This polynomial also has a degree of 3.



The third option is,
6 {x}^{2}  - 6x + 5
This last option has a degree of 2.


Therefore the correct answer is option C.
