0.12*250=p
p= number of photos
30=p
Olaf has 30 photos on his external hard drive
Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
The domain is group/set of numbers that will work for the equation
if no domain is specifiedl, then the domain is usually the set of all real numbers
to find the domain, find which numbers will violate any rules, such as dividing by zero
if there are any, then just say that the domain is all real numbers except these numbers exg
if you had an equaiton y=2/x then x cannot be zero because 2/0 is undifined and impossible so the domain would be all real numbesr except 0
domain is all real numbers
(-4,-5) would be the answer
