Answer:

2.4

Step-by-step explanation:

Look up 30-60-90 right triangle and use that formula. Since the angle in the middle is 90 degrees, it should work. The side of x would be double of the given side 1.2... this is what I would do

Step-by-step explanation:

Use the quadratic formula

−

√

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

x=2a−b±b2−4ac

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

2x^{2}+6x+4=0

2x2+6x+4=0

a={\color{#c92786}{2}}

a=2

b={\color{#e8710a}{6}}

b=6

c={\color{#129eaf}{4}}

c=4

−

⋅

√

⋅

x=\frac{-{\color{#e8710a}{6}} \pm \sqrt{{\color{#e8710a}{6}}^{2}-4 \cdot {\color{#c92786}{2}} \cdot {\color{#129eaf}{4}}}}{2 \cdot {\color{#c92786}{2}}}

x=2⋅2−6±62−4⋅2⋅4

Answer:

the second one +1.5 m/s

Step-by-step explanation:

to find the velocity you need to find the slope of the two points then just put it into the time (s) and position (m) terms which equals +1.5 m/s
