Your house is at point C. A post office is located directly west of your house at point D. Let point E represent your school, which is directly west of the post office. Find the distance from your house to your school if CD = 1.7 miles and DE = 2.4
miles.
A 3.1 miles
B. 41 miles
C. 4.3 miles
D. 5.1 miles

answer: 7

step-by-step explanation:

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:

b. f(x) = –√x + 3this is the correct answer
