Which statement correctly describes the location of the circumcenter of a triangle? Question 18 options:

A)

The circumcenter is on one of the sides of an acute triangle.

B)

The circumcenter is on one of the vertices of an acute triangle.

C)

The circumcenter is on the inside of an obtuse triangle.

D)

The circumcenter is on the outside of an obtuse triangle.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

wait this depends wether emily and zach how they are thinking.

yes they are the same.

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
