Let us check series : -10 /-2 = 5 -50/-10 = 5

so it is a geometric series with a= -2 and r= 5

sum formula for n terms of geometric series = a ( r^n -1 ) /( r-1)

here we find S5 that is n= 5 = -2 ( 5^ 5 - 1) /( 5-1)

= -2 ( 3125 -1) / 4 = -1562

second series is : 1.5/1 = 1.5 2.25/1.5 = 1.5

this is also geometric series but n = 12 a= 1 and r= 1.5

we use same formula

S12 = 1 ( (1.5) ^12 -1) /( 1.5-1) =

128.74 / 0.5 = 257.49

Last is 2/1= 2 4/2 = 2 8/4 = 2 so r = 2 a = 1 and n = 12

we use same formula 1 ( 2^12 - 1) / (2-1)

= 4095

Answers : -1562 , 257.49 , 4095

Let f (x)<br>sinx cosx, then f'(x) =<br>A. Cos2x<br>B. sin2x<br>C. tan 2x<br>D. cos2x - sin2x<br>​
Degger [83]

Answer:

A. Cos2x

Step-by-step explanation:

f(x) = sin(x)cos(x) = (1/2) sin(2x)   using double angle formula.

f'(x) = ( (1/2)sin(2x) )' = 2(1/2)cos(2x) = cos(2x)

Let d = # of dimes

Let q = # of quarters

equation #1: number of coins

    d + q = 1234

equation #2: value of coins

    0.10d + 0.25q = 290.05

Solve #1 for d:

    d=1234-q

Sub #1 into #2 and solve for q:

    0.10d + 0.25q = 290.05

    0.10(1234-q) + 0.25q = 290.05

    123.4 - 0.10q + 0.25q = 290.05

    0.15q =  166.65

    q = 1111

Now go back to d=1234-q and sub in 1111 for q to find d:

    d = 1234 - 1111

    d = 123

1111 quarters and 123 dimes.
