Answer:
slope-intercept formula -----> Y2-Y1/X2-X1
Step-by-step explanation:
X1= 2 X2= 0
Y1= -4 Y2= -4
-4+4/0-2=0
Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05

joyce
Step-by-step explanation:
60/5 =12
48/6 =8
5/40 = 1/8 so your taking it and dividing by 5
Answer:
Part A speed=96*2=192km/h
Step-by-step explanation:
Two parts, parts A and part B
Part A=200% more than B
Let part B=x
Part A=200 more than B
=2x
Speed ratio=2:1
Average speed of train=64km/h
Let Part A speed=2x
Part B speed=x
A:B=2:1
Total ratio =3
Speed in the part A can be calculated thus:
Totatl speed= ratio of speed in part A / total ratio
64=2x/3
192=2x
x=96km/h
Part A speed=96*2=192km/h
