Answer:
- 85
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
1 ← is the n th term of a geometric series
with a = 1 and r = - 2
The sum to n terms of a geometric series is
=
=
=
=
= - 85
Answer:
Step-by-step explanation:
The formula for finding the midpoint of two coordinates is expressed as;
M(X,Y) =
Given the coordinates c(-4,5) and d(-1,-4), x1 = -4, y1 = 5, x2 = -1 and y2 = -4.
For the X coordinate of the midpoint
X = x1+x2/2
X = -4+(-1)/2
X = -4-1/2
X = -5/2
X = -2.5
Similarly for Y:
Y = y1+y2/2
Y = 5+(-4)/2
Y = 5-4/2
Y = 1/2
Y = 0.5
Hence the midpoint coordinate of C(-4,5) and D (-1,-4) is (-2.5, 0.5)
6 pounds of gummy bears cost is $3.52 . Because you just needed to multiply 3.52 with 6 which will equal $3.52
You would have to use the formula, pi(r^2)*h.
0.5*0.5= 0.25
0.25*3.14=0.785
0.785* 2.5=1.9625
Your answer would be 1.9625
