If demand is D1, what is the lowest price that Stromnord can charge so that it will not run out of this model of shoe in the mon
Molodets [167]
D1 = 60 for a price of $80. Charging $80 will ensure supply exceeds demand.
___
The store apparently could charge a price slightly lower than $80, but we cannot tell from the chart how much lower.

A small radio transmitter broadcasts in a 53 mile radius. If you drive along a straight line from a city 70 miles north of the t
son4ous [18]

Answer:

29% of the drive

Step-by-step explanation:

The plot of the problem is:

Transmitter at origin (0,0)  

City to the north at (0,70)

City to the east at (74,0)

The path from city to city is a line with slope:

m = (-70)/74 = -35/37

and y-intercept at y = 70, so the equation is y = (-35/37)*x + 70.

The transmitter reach the area enclosed by the next circle:

x^2 + y^2 = 53^2

See the picture attached

The intersection is gotten from the picture or solving:

x^2 + [(-35/37)*x + 70]^2 = 53^2

the points approximately are: (24.1, 47.2) and (45.8, 26.7)

From Pythagorean theorem the total distance of the trip is:

d1 = √(70^2 + 74^2) ≈ 101.9 miles

And the distance when the signal is picked up is:

d2 =√ [(45.8 - 24.1)^2 + (47.2 - 26.7)^2] ≈ 29.9 miles

You will pick up a signal from the transmitter in (d2/d1)*100 = 29% of the drive.

How are they getting the numerator and denominator for the fractions for the coordinates? PLEASE HELP ASAP!!!!! 20 POINTS!!!!
ycow [4]

Answer:

All except from point E's y-coordinate (which is -1.5 (found it through the equation y=-1.5 and trying to see if these coordinates are solutions to the above equation) All the others are integers, which you can find through aligning the point on the axis of the chosen (y or x) coordinate.

Step-by-step explanation:

Point C has -2 x-coordinate since it is on the x=-2 line

Similarly, point D has -2 y coordinate,

point E has 2 x-coordinate and -1,5 y-coordinate

and point F , since it's the two axis' common point has coordinates of (0,0).

Hope I helped! Further explanation can be given on request on your behalf.
