Answer:
1/2
Step-by-step explanation:
16^-1/4
We know that a^ -b = 1/a^b
1/( 16^1/4)
Rewriting 16 as 2^4
1/( 2^4^1/4)
We know that a^b^c = a^ (b*c)
1/( 2^(4*4))
1/2^1
1/2
Answer:
C. 21%

Please kindly check the attached file for explanation.
Answer:
C
Step-by-step explanation:
This has to be C because you need to divide pi from r squared bc they r multiplied. Then you get a/pi = r squared. You need to find the square root of a/pi. So r equals square root a/pi.
If 15 is 20% of her money you need to multiply 15 times 5 to get her total money which is 75 $
Answer:The roots are:

and
Explanation:First, we would need to put the equation is standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
4x² - 12x + 9 - 3 = 0
4x² - 12x + 6 = 0
By comparison, we would find that:
a = 4
b = -12
c = 6
To get the roots, we would substitute in the quadratic formula shown in the attached image.
Doing this, we would find that:
either x =

or x =
