To find the discriminant we use b^2 - 4ac
equation of 4x^2 - 3x + 3 = 0
a b c
-3^2 - 4 (4)(3) = -39
if b^2 - 4ac < 0, there are 2 complex roots or...no real roots...in this case imaginary.
Answer:
It is C.
Explanation:
If you take a closer look at the data, the lower extreme is 10, and which one shows 10 as the lower extreme? It is option C.
Answer:
b=45/4
Step-by-step explanation:
This is a special triangle 30-60-90.
In big triangle hypotenuse 15, short leg x=(hypotenuse/2), x=15/2.
In smallest triangle :
1. This is also special triangle 30-60-90
2. x=15/2 hypotenuse
3. "a" is a shortest leg in the smallest triangle,
so a=(15/2)/2=15/4
a+b=15
15/4 +b=15
b=15 -15/4=15*4/4 -15/4 = 45/4
b=45/4
Answer:
3,000,000 times larger
Step-by-step explanation:
9*10^7
= 9 multiplied by 10,000,000
=90,000,000
3*10^-2
= 3 multiplied by 0.01
= 0.03
Therefore by dividing 90,000,000 by 0.03
The answer is 3,000,000
That is 3 million
