R is the rate (10%)
C=20, begiing rate
T=time=8
so
h=20(1+0.10)^8
h=20(1.1)^8
h=42.8718
ronnd
$42.87
D is answer
Step-by-step explanation:
Hope it helps you in your learning process.
We have
f(x)=<span>−x</span>²<span>+ 5x + 6
g(x)=</span><span>3x − 2
we know that
f(x)=g(x)
the solution is the intersection both graphs
using a graph tool
see the attached figure
the solution are the points(4,10)and(-2,-8)</span>
Answer:
23.5 = (2 x 10) + (3 x 1) + (5/10)
Use the midpoint formula,
(x1+x2/2,y1+y2/2)
(-1-5/2,1-3/2)
(-6/2,-2/2)
(-3,-1)
