s=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
s=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Answer:
I'm honestly proud of myself for getting this right, the answer is 123.2
Step-by-step explanation:
14 x 8.8 x 2 divides by 2 and that's your answer pretty self-explanatory and simple
Answer:
3√15/4
Step-by-step explanation:
sin x = 2/8
- from the trigonometric rule sin²x+cos²x = 1
- cos²x = 1-sin²x
sinx = 2/8
sin²x = (2/8)² = 2²/8² = 4/64
1- sin²x = 1-4/64 = 64 -4/64 = 60/64 = 15/16
cos x = √(15/16) = √15 /4
3 x cos x = 3 x √15/4 = 3√15/4
Answer:
y=ax+b
a=-0.6020457867
b=-2.256697516 <------- There is your value for b, which is the answer to the problem.
You can use these values for a and b to generate an equation in slope-intercept form, which you can then enter under Y= and view the graph.
Step-by-step explanation:
Ok so if the parenth function is y=x^2
to move it up c units, add c to whole function
to move it right c units, minus c from every x
looks like we have
y=(x-6)^2-5
add -5 to whole funciton
minus 6 from every x
means that it moved 5 units down and 6 to the right from original function if parenth is y=x^2
