Answer:
The ball will be the 7 ft high at 2 different times.
Step-by-step explanation:
The height in meters of the ball is given by the following equation:
7 feet high
The height, by the equation, is given in meters, so we have to work in meters. Since each feet has 0,3048 meters, 7 feet have have 2.1336 meters. So, we have to solve the following equation
At how many different times will the ball be 7 ft. High?
We have to find the number of solutions for the equation above.
It is given according to the value of 
. If it is positive, there are two solutions, zero one solution and negative no solutions.
In this equation 
. So
Since the coefficient is positive, the ball will be the 7 ft high at 2 different times.

Answer:
<em>Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>
Step-by-step explanation:
Take a look at the procedure below;
First simplify f ( x ) = - 4 * ( 8 )^x, such that it is ⇒
f ( x ) = - 2^2 * 8^x,
f ( x ) = - 2^2 * ( 2^3 )^x,
f ( x ) = - 2^2 * 2^3x,
f ( x ) = - 2^2 + 3x,
Now if we take a look at the domain we can see that it has no undefined points nor domain constraints, thus;
- ∞ < x < ∞
However, the range of the function is present in the form - c * n^ax + b, where f ( x ) < k, and k = 0;
f ( k ) < 0, y < 0
<em>Solution; Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>
The atmospheric pressure is 14 lb/s^2 at sea level is the answer.
