The formula t= + gives the
total time t (in hours) needed for a
boat to travel upstream a distance
of d miles and then back
downstream the same distance,
where b is the speed of the boat in
still water and c is the speed of the
river's current (both in miles per
hour). How can you write a formula
that gives the speed of the current
in terms of the other variable? What
is the formula? (3 points)

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
