The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D

Answer:
The volume of the solid figure = Volume of the first cuboid + Volume of the second cuboid
The volume of the solid figure = 15×5×5 + 5×5×10
Or, The volume of the solid figure = 375 + 250
Or, The volume of the solid figure = 625 inch³
Therefore, the volume of the solid figure = 625 inch³

Answer:
45¹³/₁₀₀
Step-by-step explanation:
The average number of hourly visitors to an art exhibit is 45.13.
We are required to write the average number of hourly visitors as a mixed number.
45.13=45+0.13
0.13=13/100 in its simplest form.
Therefore:
45.13=45+13/100
Writing this as a mixed number, we have:
45.13= 45¹³/₁₀₀
Therefore the average number of hourly visitor is given by 45¹³/₁₀₀
