The following table represents the total cost, in dollars (y) to join a gym for x number of months. the cost includes a one-time joining fee of $10. does the data in the table represent a proportional relationship or a non-proportional relationship? how do you know?
x 1 2 3 4 5
y 25 40 55 70 85

attachment is for the second question.

the graph below shows the average daily temperature over the period of a year. explain how each labeled section of the graph relates to the four seasons.

Not proportional.

A winter, B is spring, C is summer and D is fall.

Step-by-step explanation:

A proportional relationship has a constant of proportional which can be formed by a ratio between any y and x values of the function. The constant will be the same every time.

The ratio y/x is 25/1, 40/2, 55/3, 70/4, and 85/5. These simplify to 25, 20, 13.33, etc. These are not the same values. This is not proportional.

In the attached graph the lows or "valleys" are the coldest parts of the year. A and D are likely Fall and Winter. While B grows and temperatures get higher then B is likely Spring. This means C is summer since it has the highest temperatures.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
