How do you solve this?

x=5/2 and y=3

Step-by-step explanation:

since AC is a perpendicular bisector, BC=CD

so

if AC = a

using pythagorean theorem:

simplifies to:

further simplifies to:

so we now have

plugging the first equation in we get

so

y=-1 is impossible, so y=3

therefore x=15/6=5/2

a.) 23

b.) y=14

c.) 23

d.) -23

e.) T=8

f.) f=1/8

Step-by-step explanation:

a.) general equation is Asin((2π/T))

A is the amplitude. It's A value is 23

b.)  Midline = vertical_shift = 14

c.) max = positive amplitude value = 23

d.) min = negative amplitude = -23

e.) Factor out 2π from your angular frequency to get the period.

ω = π/4 = (2π)/8 = (2π)/T

Period = 8

f.) Frequency is just the inverse of the period.

f = 1/T = 1/8
