Answer:
4
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a is the first term and r the common ratio
Here r = 5 and a has to be found, thus
=
, so
= 15624
Multiply both sides by 4
15624a = 62496 ( divide both sides by 15624
a = 4
Expanded form of 582, 030
500000 + 80000 + 2000 + 30
Answer:
Step-by-step explanation:
Point of intersections of the graph with x-axis are not clear.
Let these points are x = -a, -b and c
Therefore, function representing the graph will be,
f(x) = p(x + a)(x + b)(x - c)
Since, this graph crosses y-axis at (0, -6),
f(0) = p(0 + a)(0 + b)(0 - c) = -6
-pabc = -6
p = 
Therefore, equation of the given function will be,
f(x) = 
Answer:
120 for oxen, 80 for cows, 60 for calves
o = 2x
Step-by-step explanation:
3o + 4x + 6c = 260
x = 2c
o = 2x
6x + 4x + 3x = 260
13x = 260
260 / 13 = 20
3o = 6x = 120
4x = 80
6c = 3x = 60
o = 2x
I= Prt
I= 5000*0.05*5
I= $1,250
So she will pay $ 1,250 in interest .
I hope that's help !
