Use the form a cos(bx-c) +d to find the variables used to find the amplitude, period, phase shift and vertical shift.

a would be the amplitude and is the number before cos.

In the given formula -1/2 is before cos, so the amplitude would be the positive value which would be 1/2

you are choosing betweem two health clubs. Club A offers membership for a fee of $23 plus a monthly fee of $18. Club B offers me
Lady_Fox [76]
What we could do first is for club A we can add up $23 + $18 which = $40. so the cost would for club A would be $40.

Now club B. Club B charges $14 + 19 that would = $33. so monthly it would be $33

But if you were looking how much money you would spend in 1 year you would have to multiply for club A 40 x 12 which is 480$

and the yearly cost for club B you would have to multiply 33$ times 12 which is $369 per year

Y is directly proportional to 1 over the square root of x if y = 7 when x = 36 find y when x = 4
Alecsey [184]

Step-by-step explanation:

y |X(the sign for protionality) 1/√x

y = 7 when x = 36

y = k/√x

7 = k/√36

7 = k / 6 cross multiply

k = 7×6

k = 42

find y when x is 4

y = 42/√x

y = 42/√4

y = 42/2

y = 21
