Order the group of parabolas from widest to narrowest.

Mathematics
1 answer:
Mamont248 [21]3 years ago
6 0

Answer:

\large\boxed{y=\dfrac{1}{4}x^2,\ y=-\dfrac{1}{2}x^2,\ y=\dfrac{3}{2}x^2}

Step-by-step explanation:

The equation of a parabola: y = ax²

The larger the value of |a|, the narrower the parabola.

We have the following coefficients a:

\left|\dfrac{1}{4}\right|=\dfrac{1}{4},\ \left|-\dfrac{1}{2}\right|=\dfrac{1}{2},\ \left|\dfrac{3}{2}\right|=\dfrac{3}{2},

We arrange the coefficients from the smallest to the largest:

\dfrac{1}{4}\

Therefore you have the answer:

y=\dfrac{1}{4}x^2,\ y=-\dfrac{1}{2}x^2,\ y=\dfrac{3}{2}x^2

So, the base is 20 and you will multiply the base by the height which is 15 so if you want it with the triangles and squares then, you break down the parallelogram into 2 triangles and 1 square you will get the height of the 2 triangles and the square and add them all up and you should get 300 if you need me to explain better i will!

5/6=x-10/3x+6 solution?
Ivan

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x =  - 10}}}}}

Step-by-step explanation:

\sf{ \frac{5}{6}  =  \frac{x - 10}{3x + 6} }

Apply cross product property

⇒\sf{5(3x + 6) = 6( x - 10)}

Distribute 5 through the parentheses

⇒\sf{15x + 30 = 6( x - 10)}

Distribute 6 through the parentheses

⇒\sf{15x + 30 = 6x - 60}

Move 6x to left hand side and change it's sign

⇒\sf{15x - 6x  + 30 =  - 60}

Collect like terms

⇒\sf{9x + 30 =  - 60}

Move 30 to right hand side and change it's sign

⇒\sf{9x =  - 60 - 30}

Calculate

⇒\sf{9x =  - 90}

Divide both sides of the equation by 9

⇒\sf{ \frac{9x}{9}  =   \frac{ - 90}{9} }

Calculate

⇒\sf{x =  - 10}

Hope I helped!

Best regards!!
