Answer:
The exponents that should be multiplied are 073.78.
Step-by-step explanation:
One form of the equation of a vertical parabola is y = x^2, which is the same as y-0 = a(x-0)^2.
If the coefficient a is positive, the parabola opens up. If a is - the parabola opens down.
The vertex of this parabola is (0,0).
More generally, y - k = a(x - h)^2 represents a vertical parabola that opens up if a is + and opens down if a is - and has its vertex at (h,k).
Often a = 1. If a is greater than 1, the graph of the parabola is stretched vertically; if less than 1, the graph is compressed vertically (and thus appears to be flatter).
y - k = a(x - h)^2 is called the 'general vertex form' of a vertical parabola.
This is a quadratic equation. With some algebra, we could rewrite
y - k = a(x - h)^2 in the form y = ax^2 + bx + c.
x-intercepts of this parabola, if any, can be found using the quadratic formula, involving the constant coefficients a, b and c.
Pebble falls into the pond from the surface and it descends at a rate of 2 feet per second.
So basically, the pebble is descending or falling down at 2 feet per second which means after every 1 second, it goes 2 feet down.
The equation to represent the depth of the pebble with time is given by:
Where, 'd' is the depth after certain time and 't' is the time in seconds.
Now, we need to find the depth of the pebble after 5 seconds.
Plugging the value 
, we get:
So, after 5 seconds the pebble will be at the depth of 10 feet.
If you mean solving by rearranging the formula:
