We have that
x------------------> <span>represent the number of hours Steven babysits
y----------------- > </span><span>represent the amount he charges
for x=6 hours
y=</span><span>$37.50 ----------------> y/x=37.5/6=6.25
</span>for x=8 hours
y=$50---------------------> y/x=50/8=6.25
therefore
y=6.25x
the answer is
y=6.25x
Part A
t = 1
order pair (1 , 1,200)
t = 2
order pair (2 , 2,400)
part B
p = 1,200t
She is right, however her explanation is wrong.
In order to find the unit price, you need to divide the amount by the cost.
You will then see that 12 divided by 2.39 < 18 divided by 3.39.
The smaller unit price is obviously the better buy.
Answer:
Let the distance between woman and pole be "x".
From diagram,
In ΔOAB,
tan 18 =
tan 18 =
∴ x = ................ (1)
In ΔOBC
tan 14 =
tan 14 =
y = x × tan 14 ..............(2)
equating (2) in (1), we get;
x =
x =
∵ tan 18 + tan 14 = 0.574
<em>∴ x = 113.2 ft</em>
<em>i.e. The her distance from the pole is 113.2 ft.</em>
