Fast ! 1.) classify the sequence as arithmetic, geometric, or neither. if there is not enough information to classify the sequence, choose not enough information. (3,-1,1/3,-1/9) 2.) write the first five terms of the geometric sequence with a1=-2 and common t=ratio r=-5/2 a.) (-2,-9/2,-7,-19/2) b.) (-2,-5,-25/2,-125/4) c.) (2,-5,25/2,-125/4) d.) (-2,5,-25/2,125/4) 3. a rubber ball is dropped from the top of a building, which is 40 ft. above the ground. each time the ball hits the sidewalk, it rebounds to 77% of its previous height. how high will the ball rebound after its sixth bounce? round your answer to the nearest 10th. a.) 8.3 ft b.) 10.5ft c.) 10.8 ft d.) 1,230.0 ft

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
