An egg is dropped from the window of am building. The height, in feet, of the egg (t)

seconds after it is thrown is represented by d=16^t-7t+61 . How many seconds after the egg is thrown will it be 10 feet from the ground?

Therefore,

After 1.58 seconds  the thrown egg will it be 10 feet from the ground.

Step-by-step explanation:

Given:

An egg is dropped from the window of am building. The height, in feet, of the egg "t"  seconds after it is thrown is represented by

To Find:

Time t = ? when d = 10

Solution:

...Given

Put d = 10  for time, t

Which is a Quadratic Equation

We will calculate "t" by Formula Method

For a Quadratic Equation ax² + bx + c = 0 we have

On Comparing we get

a = 16 , b = 7, c = -51

As time cannot be negative

So, t = 1.58 s

Therefore,

After 1.58 seconds  the thrown egg will it be 10 feet from the ground.
