Answer:
14.86854, or 15
Step-by-step explanation:
She runs 8/45 miles per min
The general formula for the sum of the n terms of a geometric progression is:
Sn = A1 (1 - r^n) / (1 - r)
In this case, n = 8; A1 = - 11, r = -4
S8 = -11 (1 - (-4)^8) / (1 -(-4)) = 144,177
Answer: option c.
Answer:
Refer the attached figure.
Step-by-step explanation:
Given : System of equation 
To find : Which graph represents the solution to the given system?
Solution :
Equation
plotted with a red line passing through (-1,0) and(0,4).
Equation
plotted with a blue line passing through (0,-3) and(0.75,0).
As their slopes are equal i.e. m=4.
So, the equation of lines are parallel.
There is no solution of the equations.
Refer the attached figure of the equations.
