Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
Answer:
speed greater than 0.08 mi/min
Step-by-step explanation:
given data
distance = 2 mi
time = 25 min
to find out
the distance you travel and your speed and time related
solution
we know that distance is
distance = speed × time ...............1
so at park at most 25 min
so we need time = 
so here
we know
so
so we can say that he need to run at speed greater than 0.08 mi/min
Answer:
Excuse me if this is wrong but I think you have to multiply 3 x 2.4 which is 7.2 and that is greater that 3.0.
Step-by-step explanation:
Answer:
last choice
Step-by-step explanation:
If we are looking at positive integers and we take out the odd ones, the only one's that are left are the even ones.
So last choice. (Also I assume AC meant the complement of A)
Answer:
See below. <u><em>I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3</em></u>
Step-by-step explanation:
Substitute the value of x given in f(x) into the equation f(x) = 8x^2 - 7x + 3
For example, f(0) would be f(0) = 8(0)^2 - 7(0) + 3. f(0) = 3
f(-2) would be f(-2) = 8(-2)^2 - 7(-2) + 3.
= 8*4 + 14 +3
= 32 + 17 therefore f(-2) = 49
