Answer:
-5
negative nine-halves
Step-by-step explanation:
we know that
In the quadratic equation
If
then
The system has no real numbers solutions
we have
so
substitute
<u><em>Verify each case</em></u>
case 1) -5
For c=-5
substitute
------> is true
therefore
The value of c=-5 will cause the quadratic equation to have no real number solutions
case 2) negative nine-halves
For c=-9/2
substitute
------> is true
therefore
The value of c=-9/2 will cause the quadratic equation to have no real number solutions
case 3) negative one-quarter
For c=-1/4
substitute
------> is not true
therefore
The value of c=-1/4 will not cause the quadratic equation to have no real number solutions
case 4) 1
For c=1
substitute
------> is not true
therefore
The value of c=1 will not cause the quadratic equation to have no real number solutions
case 5) 9 Over 4
For c=9/4
substitute
------> is not true
therefore
The value of c=9/4 will not cause the quadratic equation to have no real number solutions

Answer:
80.66
Step-by-step explanation:
Since we have three variables,
Therefore:
Using the above:
f(4.02, 3.99, 6.97) =81+ 8(4.02 - 4) + 8 (3.99 - 4) +14(6.97-7)=80.66.
The approximation of is 80.66000.
28.2/9.4= 3
g=3
Just divide like normal.
The answer as a decimal is 0.32
