Last year the local dance club had 64 members. this year it has 73 members. Calculate the percentage increase in the membership.

14.06%

Step-by-step explanation:

To find the percent increase, find the difference between the original and new amounts, divide it by the original amount, then multiply by 100:

73 - 64 = 9, so the difference is 9.

Divide this by the original and multiply by 100:

(9 / 64) x 100

= 14.06

So, the percent increase in the membership is 14.06%

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
