Jay on started off his penny collection with 1 penny. He then adds 5 pennies to his collection each day. How could you change th
nata0808 [166]

Answer:

By doubling each day

Step-by-step explanation:

Jay is increasing  daily a fixed amount of pennies to his collection.  That's an arithmetic series, because to obtain the next term you have to do an addition.

To get a geometric series or progression you have to find the next term through multiplication.

So, if he wants to convert his series into a geometric series, he'd have to double his contribution to his collection each day (as an example).

Solve for x<br>6x²+2x-12​
dem82 [27]

Answer:

Step-by-step explanation:

Solving for x means you have to factor. First factor out the GCF of 2 to get:

2(3x^2+x-6) and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:

1, 18

2, 9

3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:

x=\frac{-2+/-\sqrt{2^2-4(6)(-12)} }{2(6)} and

x=\frac{-2+/-\sqrt{4+288} }{12} and

x=\frac{-2+/-\sqrt{292} }{12} and

x=\frac{-2+/-\sqrt{4*73} }{12} and

x=\frac{-2+/-2\sqrt{73} }{12} which finally simplifies to

x=\frac{-1+/-\sqrt{73} }{6} No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!

How much would it cost to buy 3 $13 battery packs and 3 $22 copper wires
Makovka662 [10]
It would cost $105 because if you do 13+13+13= 39
22+22+22= 66
66+39= 105.
