PLEASE HELP CORRECT AND 1ST ANSWER IS BRAINLIEST
poizon [28]

Answer:

<em>m<A = 40 deg</em>

<em>m<B = 60 deg</em>

<em>m<C = 80 deg</em>

Step-by-step explanation:

2x + 3x + 4x = 180

9x = 180

x = 20

m<A = 2x = 2(20) = 40

m<B = 3x = 3(20) = 60

m<C = 4x = 4(20) = 80

m<A = 40 deg

m<B = 60 deg

m<C = 80 deg

A sequence is defined by the recursive function f(n + 1) = –10f(n). If f(1) = 1, what is f(3)?
kotykmax [81]

Answer:

f(3) = 100

Step-by-step explanation:

Using the recursive formula and f(1) = 1 , then

f(2) = - 10 f(1) = - 10 × 1 = - 10

f(3) = - 10 f(2) = - 10  × - 10 = 100
