Answer:
8.75
Step-by-step explanation:
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
Ok so 60 centimeters is the height of it... you divide that by 2 and square it and get 30^2.
and then minus that by 27 bc thats what your suppose to minus that number by
and times it by 5
wait the answer is right below it T.T like it shows you on the right how you do it. and what its called is on the left...
