2,5, 25/2, ... <br> find the 10th term
notka56 [123]

Answer:

The  10^{th} term of the given sequence

t_{10} = \frac{5^{9} }{2^{8} }

Step-by-step explanation:

<u>Step(i):-</u>

Given sequence   2 , 5, \frac{25}{2}

First term    a = 2

The difference of given geometric sequence

    d = \frac{r_{2} }{r_{1} } = \frac{5}{2}

<u><em>Step(ii):-</em></u>

The  n^{th} term of the given sequence

t_{n} = ar^{n-1}

The  10^{th} term of the given sequence

t_{10} = (2)(\frac{5}{2} )^{10-1}

t_{10} = (2)(\frac{5}{2} )^{9}= \frac{5^{9} }{2^{8} }

A. Shift left 3 units, shrink vertically to 1/2 of the original height, then shift up 5 units.

B. Shift right 3 units, stretch vertically by a factor of 2, then shift up 5 units.

C. Shift up 3 units, stretch horizontally by a factor of 2, then shift left 5 units.

D. Shift 5 units right, stretch vertically by a factor of 3, then shift up 2 units.

Kevin and Randy Muise have a jar containing 70 coins, all of which are either quarters or nickels. The total value of the coins
Nikitich [7]

Answer:

50 nickels, 20 quarters.

Step-by-step explanation:

System of equations (q = # of quarters, n = # of nickels):

<em>q + n = 70, 0.25q + 0.05n = 7.50</em>

the first equation can be changed to q = 70 - n, so we are able to <em>substitute q with 70 - n</em>.

So, it will look like <em>0.25*70 - 0.25n + 0.05n = 7.50</em>. This can be simplified to <em>0.2n = 10</em>, which means that n = 50.

Knowing that we can solve <em>q + 50 = 70</em>, which means that q = 20.
