For the funtion f(x)= (x+7)^5, Find f^-1 (x) a: f^{-1}(x)=\sqrt[5]{x}+7f −1(x)=5x +7
b: f^−1(x)=x 5 −7
c: f −1(x)=5sqrtx−7
d: f ^−1(x)= 5sqrtx−7

you should at least use a calculater

step-by-step explanation:

the correct is answer is a 9-sided polygon!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
