Assume that the statement is true for n equals K prove that it must be true for n equals k plus one therefore proving it true for all natural numbers, n. Hand since the total number of dots increases by and each time prove that d(k)+(k+1)=d(k+1).

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

i believe a. 12x≥120 is the answer

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
