Answer:

Step-by-step explanation:

\sum^{12}_{r=1} r^2 = \frac{12(12+1)(2*12+1)}{6}= A

\sum_{r=3}^{12}= \sum_{r=1}^{12} - (r_1+r_2)

r_1= 1^2

r_2= 2^2

you do your math!!

Identify the inverse of the following.
posledela

Answer:

f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}

Step-by-step explanation:

Given function is,

f(x) = -8x² + 4

Step to find the inverse of the function,

Step 1

Write the function in the form of an equation,

y = -8x² + 4

Step 2

Interchange the variables 'x' and 'y',

x = -8y² + 4

Step 3

Solve the equation for y,

x = -8y² + 4

x - 4 = -8y²

-x + 4 = 8y²

y² = \frac{1}{8}(-x+4)

y=\sqrt{\frac{1}{8}(-x+4)}

Therefore, inverse of the function f(x) will be,

f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}
