The tax rate as a percent, r, charged on an item can be determined using the formula - 1 = r, where c is the final
cost of the item and p is the price of the item before tax. louise rewrites the equation to solve for the final cost of the
item: c = p(1 + r). what is the final cost of a $40 item after an 8% tax is applied?

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

0.32
