Enter the finite geometric series from its given description, and then enter its sum.

Mama L [17]

Answer:

$a_n= 4(-5)^{(n-1)}$

-10416

Step-by-step explanation:

a = 4

r = -5

geometric series: $a_n=ar^{(n-1)} = 4(-5)^{(n-1)}$

Determine which term = -12500:

$a_n=-12500$

$4(-5)^{(n-1)}=-12500$

$(-5)^{(n-1)} = -3125$

$(5)^{(n-1)} = 3125$

$(n-1)ln(5) = ln(3125)$

$n-1 = ln(3125)/ln(5) = 5$

$n = 5 + 1 = 6$

$a_6=-12500$

Using geometric sum series formula: $S_n=\frac{a(1-r^n)}{1-r}$

Therefore, $S_6=\frac{4(1-(-5)^6)}{1-(-5)} =\frac{-62496}{6} =-10416$

PLEASE HELP ASAP 30 POINTS!!!

Helen [10]

Answer:

a=1, b=2, c=5, d=1, e=6

Step-by-step explanation:

$\frac{1}{2} \times (2x+4)(x+3)=(x+2)(x+3)=x^2+5x+6\\$

So $a=1, b=2, c=5, d=1, e=6$

For 3 pink flowers=2 white flowers

1 pink flower=2/3 white flowers

Now

72 pink flower=(2/3)×72 white flowers

72 pink flowers=2×24 white flowers

72 pink flowers=48 white flowers

If the straight line passing through A(-7, -5) and B(-3, x) is parallel to another straight line of slope 2, find the value of x

Ostrovityanka [42]

X=3; you can set up a proportion using the slope equation. So (y[sub2]-y[sub1])/(x[sub2]-x[sub1])=2/1 then plug in the values and simplify. Then cross multiply and solve for x. Rest of work shown in the picture
