Acompany rents diving equipment for a fixed amount plus a fee based on the number of days for which the equipment is rented. the table below shows the total charges, y, in dollars, of renting diving equipment for x number of days:

diving equipment rentals
number of days
(x) total charges (dollars)
(y)
0 5
1 20
2 35

what is the fixed amount charged?
$2
$5
$15
$20

The answer is B. $5

*i got an 100 on this test so i'm positive

Notice how the description says "a fixed amount plus a fee based on the number of days." And the question only asks for the fixed amount, not including the fee.

For the first rental, they had only been renting but had not kept it for a day yet, so the fee is not added and there is only the cost of the fixed amount for the equipment, which is $5. This shows that when they keep the equipment for a day, the fee is $10 added on each day the equipment is kept.

So, taking away the fee for the numbers of days, the points would be (0,5), (1,10), (2,15). Add on another $10 per day onto the y colomn and you get the table we have here.

Good luck on your quiz, hope you understood all of that :)

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
