1) Ellen must decide between two cameras. The first camera costs $47.00 and uses two alkaline AA batteries. The second camera costs $59.00 and uses one $4.95 lithium battery. She plans
to use the camera frequently enough that she probably would replace the AA batteries six times
a year for a total cost of $11.50 per year. The lithium battery, however, will last an entire year.
a. Let x represent the number of years, and let y represent the cost in dollars. Write an
equation to represent the overall expense for each camera.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
