Answer:

2, 4, 12, 48, 240

Step-by-step explanation:

We have the recursive formula   a_n = 2*(n!)

Find:

a_1 =  2* 1! = 2

a_2 = 2*(2!) = 4

a_3 = 2*(3!) = 2*6 = 12

a_4 = 2*(4!) = 2*24 = 48

a_5 = 2*(5!) = 2*5*24 = 240

4. If y varies directly as x and y = 72 when x = 6 find y when x = 4.

You would do 72 / 6 to find how many y per x which is 12, and multiply that which is 48.

Daphne bought a house for 335,000. She financed 276,475 of the purchase price with a 30 year, fixed rate mortgage with 5.65% int
sweet-ann [11.9K]
First find the yearly payment using the formula of the present value of annuity ordinary
The formula is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value 276475
Pmt yearly payment ?
R interest rate 0.0565
N time 30 years

Now solve for pmt
The formula change to be
Pmt=pv÷ [(1-(1+r)^(-n))÷r]
Plug in the equation above
Pmt=276,475÷((1−(1+0.0565)^(−30))÷(0.0565))=19,339.22

Now find the cost of the principle and interest after 30 years by multiplying the yearly payment by the time

19,339.22×30=580,176.60...answer

Hope it helps:-)

Answer:

to find your solution you must multiply the amount needed for 1 recipe meaning 2T , now times by 120 since you need that much for that is called for leading you 240T now you must convert 240T into mL (1 T is 15mL) now you get 3,600mL, to find the amount of bottles needed now you divide 3,600mL by 750mL per bottle to get your final sum of 4.8 bottles of olive oil.

Step-by-step explanation:

2T × 120 = 240T

240T × 15mL = 3,600mL

3,600mL ÷ 750mL = 4.8

4.8 bottles of olive oil
