For the time period of the projectile at least 192 feet above the ground is between 2 second and 6 second
Since s=128t-16t2, we want to know the 2 times where 128t-16t2=192, as those two values will be the begin and end times of the interval in question. We can rewrite that equation in standard quadratic equation form:
16t2-128t+192=0 or, simplified, 8t2-64t+96=0
or t2-8t+12=0
since it is now in quadratic form, we can solve using the quadratic formula:
t = 2 and 6
So the time period from approximately 2 second and 6 second has the projectile above 192 feet.

The answer is all real numbers greater than or equal to -3, as domain and range.
What is the domain and range of function?
A function's domain and range are its components. A function's range is its potential output; its domain is the set of all conceivable input values. Domain, Function, and Range. If a function f: A B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The image of an element 'a' under a relation R is provided by 'b,' where (a,b) R. The set of photographs makes up the function's range.
The domain of a relation or a function is the set of all possible values for an input in that relation/function.
The range of a relation or function is the set of all possible values that can be the result of a relation or function.
From the graph, nothing can be seen on the left side of x = - 3 and the graph is continuous and going in the direction of infinity on the right side of the x axis.
Hence all real numbers greater than or equal to -3

The sum is zero so neither positive or negative
The answer to your math question is $36.50.
Answer:
8.67
Step-by-step explanation:
-9t+18= -60
60+18=9t
78=9t
t= 78/9
=8.66
