Answer:
The discriminant is 0
Step-by-step explanation:
If b² - 4ac = 0 then the roots are real and equal
Since there is only one x- intercept then this condition applies
The 40th best out of 600 means his rank is 40th out of 600, or 40 out of 600.
Answer:
3619.6cm^3
Step-by-step explanation:
Given data
Daimeter= 24cm
Radius= 12cm
The formula for finding the volume of the hemisphere is given below
V = 2/3*π*r³
Substitute
V= 2/3*3.142*12^3
V= 2/3*3.142*1728
V= 10858.752/3
V=3619.6cm^3
Hence the volume is 3619.6cm^3
