The statement above is true. Polar equations indeed can describe graphs as functions, even if when the equations in the rectangular coordinate system are not one of the functions. Polar equations can be graphed accurately using hands by using the Polar Coordinate System.

The drain in your 45-gallon bathtub is partially clogged, but you need to take a shower. The shower head had a flow rate of 2.25

Helen [10]

Answer:

$Time = 1.978\ min$

Step-by-step explanation:

Given

$R_1 = 2.25\ gal/min$ --- Flow rate of the shower

$R_2 = 20.5\ gal/min$ --- Drain rate of the bathtub

$Size = 45gal$ -- Bathtub size

Required

Determine the maximum time of shower

First, we calculate the rate at which the bathtub fills.

$R_3 = R_1 + R_2$

$R_3 = 2.25 + 20.5$

$R_3 = 22.75gal/min$

The maximum time of shower is:

$Time = \frac{Size}{R_3}$

$Time = \frac{45gal}{22.75gal/min}$

$Time = 1.978\ min$

What is the slope of a line that is perpendicular to the line y=8x+5

statuscvo [17]

Answer:

-1/8

Step-by-step explanation:

Perpendicular slopes are negative reciprocals

The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.

Negative:

8/1--> -8/1

Reciprocal:

Flip the numerator and denominator

-8/1--> -1/8

So, the perpendicular slope of 8 is -1/8
