We have to find horizontal component of Mayosons velocity.

#a

\\ \tt\bull\leadsto V_x=vsin\theta

\\ \tt\bull\leadsto V_x=2.5sin36

\\ \tt\bull\leadsto V_x=2.5(0.58)

\\ \tt\bull\leadsto V_x=1.45m/s

#b

Here 2 vectors A=8 and B=2.5

\\ \tt\bull\leadsto \overrightarrow{R}

\\ \tt\bull\leadsto \sqrt{A^2+B^2+2ABcos\Theta}

\\ \tt\bull\leadsto \sqrt{8^2+2.5^2+2(8)(2.5)cos36}

\\ \tt\bull\leadsto \sqrt{64+6.25+40(0.8)}

\\ \tt\bull\leadsto \sqrt{70.25+32}

\\ \tt\bull\leadsto \sqrt{102.25}

\\ \tt\bull\leadsto 10.15m/s

A parabola intersects the x-axis at x=3, equals, 3 and x=9.
kakasveta [241]

Answer: x is 6

Step-by-step explanation:

where a and b are x intercepts given to us.

So rewriting in factored form:

y = (x-3)(x-9)

so now you have to simplify it using the formula y= ax^{2}+ bx-c

y= x^{2}- 12x+27

so with this formula x=\frac{-b}{2a} we can find the x coordinate

x=\frac{-(-12)}{2(1)}

and the answer would be 6
