If f[6} = x ^ -2x , find: f [6} =
ASHA 777 [7]

Answer:

1/ 6^12

Step-by-step explanation:

f[x} = x ^ (-2x)

f(6) = 6 ^ (-2*6)

      = 6 ^ -12

   We know the negative exponent moves it to the denominator

     = 1/ 6^12

A class consists of 63 women and 86 men. If a student is randomly selected, what is the probability that the student is a woman?
solmaris [256]
First, we need to get the total number students by adding the number of men and women. 63 + 86 = 149. This is the total number of samples. To get the probability that a randomly selected is a woman, we can write the ratio as 63:149 or the probability is 63/149.

Anyone know how to do these?
erastovalidia [21]

Answer:

B. 1/m¹⁸

Step-by-step explanation:

To simplify the equation, we start with the values inside the brackets.

Therefore  m⁻¹m⁵ results to m⁴.

This is because the sign between the m⁻¹ and m⁵ is multiplication, and when multiplying figures that have a similar base, we add the indices.

that is, -1+5=4

then we divide m⁴ by m⁻², that is, m⁴/m⁻²=m⁶

To divide figures that have the same base we subtract the powers.

That is, 4-(-2)=6

the resulting expression from inside the brackets will be (m⁶)³ which results to m⁻¹⁸ which is the same as 1/m¹⁸
