A. 3 times 10^4
90000000 divided by 3000 is 30000 which happens to be equal to 3 times 10^4

If you want to learn how to do this just take your whole number ex: 3 and put 10^6 and you will have 3 followed by 6 zeros. The ^ is just how many zeros will follow your whole number at first.

The vertex of this parabola is at (2.-3). When the yvalue is -2, the xvalue is 5. What is the coefficient of the squared term in
tatiyna

Answer:

The coefficient of squared term is 1/9

Step-by-step explanation:

The vertex of parabola is (2.-3)

We know the vertex form of a standard parabola

y=a(x-h)^2+k,\text{ where (h,k) is vertex}

Plugging values of h and k, h= 2, k = -3

y=a(x-2)^2-3

Now, x=5, y=-2

-2=a(5-2)^2-3

-2=9a-3

9a=1

a=\frac{1}{9}

Thus, the coefficient of squared term is 1/9
