f(1)=3 and

(

−
3
f(n)=f(n−1)−3 then find the value of
f
(

)
f(4).

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

answer: correct choices are 1, 3 and 5
