A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be desc

The equation of the new route if it is to be perpendicular to the old route and will go through point (P, Q) is y - Q = -\frac{5}{2}(x - P)

Since the equation of the path of the old route can be described as y = two fifthsx − 4, it is y = \frac{2}{5}(x - 4)

Now the gradient of this old route is m = 2/5.

Since the new route is perpendicular to the old route, if we let its gradient be  m', then mm' = -1 (since the routes are perpendicular).

So, m' = -1/m

m' = -1/2/5

m' = -5/2

So, the gradient of the new route is m' = -5/2.

Since the new route passes through the point (P, Q), the equation of the new route passing through this point is given by

(y - Q)/(x - P) = m'.

\frac{y - Q}{x - P} = m'

This is the equation of the new route given in gradient form where m' is the gradient of the new route.

Since m' = -5/2,

\frac{y - Q}{x - P} = m'

\frac{y - Q}{x - P} = -\frac{5}{2}

y - Q = -\frac{5}{2}(x - P)

So, the equation of the new route if it is to be perpendicular to the old route and will go through point (P, Q) is y - Q = -\frac{5}{2}(x - P)

The local bakery uses 1.75 cups of flour in each batch of cookies. The bakery used 5.25 cups of flour this morning. If there are
Firdavs [7]

Answer: 180 cookies


Step-by-step explanation: If 1.75 cups of flour is required to make a batch and the bakery used 5.25, the bakery made 3 batches, since 1.75(3) is 5.25. One dozen is 12 cookies, and there are 5 dozen cookies in each batch. If there are 3 batches, then there are 15 dozens of cookies. 15(12) is 180.

572000 square miles rounded ro the nearest hundred thousand
baherus [9]

It would be rounding it to 600000 because 600000 is the closest 100000x amount where x is an integer. I hope this helped and if I am right could I have brainliest? :)
