1. a white candle has a circumference of 18.8 inches. what's the radius?

Mathematics
1 answer:
faltersainse [42]2 years ago
6 0

Answer:

  • 3 in
  • 3.5 in

Step-by-step explanation:

<u>Circumference formula:</u>

  • C = 2πr,
  • where π = 3.14, r - radius

1.

  • C = 18.8 in
  • 2*3.14r = 18.8
  • 6.28r = 18.8
  • r = 18.8/6.28
  • r = 2.99 ≈ 3 in

2.

  • C = 22 in
  • 6.28r = 22
  • r = 22/6.28
  • r ≈ 3.5 in

362.50 for tennis and golf balls.
To find the answer divide the dollar amount by how many cans or boxes each cost then multiply that answer by the total amount purchased.
Golf balls
45/2=22.50 each box
22.5*5=112.50 total
Tennis balls
30/12=2.50 each can
2.50*100 = 250.00
add the dollar amounts  together
112.50+250.00 =362.50

Answers:

  1. Exponential and increasing
  2. Exponential and decreasing
  3. Linear and decreasing
  4. Linear and increasing
  5. Exponential and increasing

=========================================================

Explanation:

Problems 1, 2, and 5 are exponential functions of the form y = a(b)^x where b is the base of the exponent and 'a' is the starting term (when x=0).

If 0 < b < 1, then the exponential function decreases or decays. Perhaps a classic example would be to study how a certain element decays into something else. The exponential curve goes downhill when moving to the right.

If b > 1, then we have exponential growth or increase. Population models could be one example; though keep in mind that there is a carrying capacity at some point. The exponential curve goes uphill when moving to the right.

In problems 1 and 5, we have b = 2 and b = 1.1 respectively. We can see b > 1 leads to exponential growth. I recommend making either a graph or table of values to see what's going on.

Meanwhile, problem 2 has b = 0.8 to represent exponential decay of 20%. It loses 20% of its value each time x increases by 1.

---------------------

Problems 3 and 4 are linear functions of the form y = mx+b

m = slope

b = y intercept

This b value is not to be confused with the previously mentioned b value used with exponential functions. They're two different things. Unfortunately letters tend to get reused.

If m is positive, then the linear function is said to be increasing. The line goes uphill when moving to the right.

On the other hand if m is negative, then we go downhill while moving to the right. This line is decreasing.

Problem 3 has a negative slope, so it is decreasing. Problem 4 has a positive slope which is increasing.

How can you use a rate to compare the costs of two boxes of cereal that are different sizes?
Leya [2.2K]
If you are given a unit rate (ex: $0.59 per ounce) then you can multiple this by the weight of the cereal to find the cost of the entire box. Do this for both boxes, and then compare the costs.

Hope this helps. I'm not sure that I'm on the right path, but I can help you further if you provide more details.

Good luck!
