Kylie starts with $145 in her piggy bank. each month she adds $20. which recursive function rule models the total amount in kylie’s piggy bank at the end of each month? an=145+an−1 and a1=20 an=145⋅an−1 and a1=20 an=20⋅an−1 and a1=145 an=20+an−1 and a1=145

Kylie's first month collection, a1= $ 145

Second month collection , a2= $145+ 20

Third month collection, a3  = $145 +2*20

.

.

.

.

so for n months collection = an-1+20

We get an= 20 + an-1  and a1=145

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: about 22.67
