Find the equation of a parabola with a vertical axis and its vertex at the origin and passing through the point (-2, 3).
jonny [76]

Answer:

y=\frac{3}{4}x^2

Step-by-step explanation:

Hi there!

Because we're given the vertex of the parabola, we can determine its equation in vertex form:

y=a(x-h)^2+k where the vertex is (h,k)

Plug in the vertex (0,0)

y=a(x-0)^2+0\\y=a(x)^2\\y=a(x-0)^2+0\\y=ax^2

Now, we must solve for a. Plug in the given point (-2,3) and solve for a:

3=a(-2)^2\\3=4a\\\frac{3}{4} =a

Therefore, the value of a is \frac{3}{4}. Plug this back into y=ax^2:

y=\frac{3}{4}x^2

I hope this helps!

What is the difference between
ankoles [38]

we are given

\sum _{n=0}^4\:\left(1+3n\right)

we can find it's sum

\sum _{n=0}^4\:\left(1+3n\right)=(1+3*0)+(1+3*1)+(1+3*2)+(1+3*3)+(1+3*4)

\sum _{n=0}^4\:\left(1+3n\right)=35

now, we can find second sum

\sum _{i=2}^6\:\left(3i-5\right)=(3*2-5)+(3*3-5)+(3*4-5)+(3*5-5) + (3*6-5)

\sum _{i=2}^6\:\left(3i-5\right)=35

so, we can see that

both sums are 35

so, their difference will be 0
