admission fee of $2 a person. C is the cost of admission and P for people. Write an equation relating C to P

algol [13]

Answer:

C = 2P

the total cost of admission equals 2 dollars per person x the number of people. for example if you had 10 people for the price of 2 bucks each the total cost would be 20 dollars.

G "a curve passes through the point" and has the property that the slope of the curve at every point p is twice the y-coordinate

Oksanka [162]

Unfortunately, you have not shared the point through which the curve passes. Would you please do that now.

Just supposing that the graph passes through the point (2,2) (which I have invented as an example):

Write the differential equation dy/dx = 2y. Rewrite this as dy/y=2dx. Integrating both sides, ln|y|=2x+ln|c| (where c is just a constant of integration).

Solving for y: ln|y|-ln|c|=2x, or ln|y/c|=2x

then y/c=e^(2x), or y=c*e^(2x). What is the value of c? To determine this, let x=2 and y=2:

2=c*e^(2[2]) after substituting the coordinates of the point (2,2). Then

2=ce^4, or c=1/[e^4].

Substituting this c into the solution,

y= (1/[e^4])e^[2x]

This solution can be used as is, or you could try simplifying it.
\
Note that if your graph goes through some point other than (2,2), the correct answer to this problem will be different.

Determine if xy is tangent to circle z

Kisachek [45]

Hi there!

When a segment is tangent to a circle, it is perpendicular to the radius. If you're given measurements, like the image below, you can use the pythagorean theorem to determine if the triangle is a right triangle. If the triangle is right, then the segment is tangent to the circle.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Convert 30 ft per s to mi per min.<br><br> 5280 ft = 1 mi<br><br> Round to nearest hundredth.

Natali5045456 [20]

Divide 30 ft by 5280 ft and you get 0.00568182 then round that number
