Use the distance formula 3 times to determine what type of triangle DEF is if it has coordinates D(2, 1), E(3, 5), and F(6, 2) (just write the number you get under the square root symbols in the blanks below, in order) a) What is the length of DE?

b) What is the length of EF?

c) What is the length of DF

d) What type of triangle is DEF, Scalene, Isosceles, or Equilateral? Watch your spelling. (20 points)

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
