Answer:
<h2>$16,104.35</h2>
Step-by-step explanation:
the expression for compound interest is given as

A=$20,000
P=?
r=7.25%=0.0725
n=52 weeks
t=3 year

the manager need to invest $16,104.35
Let
A (x1,y1)-------> (1,5)
B (x2,y2)------> (5,10)
C (x3,y3)------> (9,15)
D (x4,y4)------> (13,20)
find the slope
AB
m=(10-5)/(5-1)-----> m=5/4
find the slope
CB
m=(15-10)/(9-5)-----> m=5/4
find the slope
DC
m=(20-15)/(13-9)-----> m=5/4
so
<span>the relationship shown is linear
</span>
<span>to model the data with an equation find the equation of a line
</span>with m=5/4 and point A (1,5)
y-y1=m*(x-x1)-----> y-5=(5/4)*(x-1)----> y=1.25x-1.25+5-----> y=1.25x+3.75
the equation to model data isy=1.25x+3.75
see the attached figure
Answer:
x=81
y=99
z= 129
Step-by-step explanation:
the 3 angles of a triangle add to 180 degrees
51 + 48 + x = 180
99 + x = 180
subtract 99 from each side
99 + x -99 = 180 -99
x = 81
x+y = 180 they make a straight line
81+ y = 180
subtract 81 from each side
y = 180-81
y = 99
z+ 51 = 180 they make a straight line
subtract 51 from each side
z+51-51 = 180 -51
z = 129
