Answer:
$20 per day with a $50 fee
Step-by-step explanation:
For 1 day, the gold fee is $70. For 2 days, the gold fee is $90. This can be written as the ordered pairs (1, 70) and (2, 90).
To find the daily fee, we will find the slope between the points:
Next we will use point-slope form:
y-y₁ = m(x-x₁)
y-70 = 20(x-1)
Use the distributive property:
y-70 = 20(x)-20(1)
y-70 = 20x-20
Add 70 to each side:
y-70+70 = 20x-20+70
y = 20x+50
This means the fee is $50.
Draw 1/2 shape and just put the divide sign and the draw 1/4.
Step-by-step explanation:
The difference quotient is simply the slope of the line connecting two points on a curve. For the best approximation, we should use points that are closest to x = 0. In this case, the points are (-0.001, 1.999) and (0.001, 2.001).
m = (2.001 − 1.999) / (0.001 − (-0.001))
m = 1
Answer:
800
Step-by-step explanation:
In order to get the new population of bacteria in <em>690 minutes</em>, you have to know how often the bacteria will divided in the time frame. So, you have to <em>divide </em><em>690 minutes </em><em>by </em><em>230 minutes.</em>
- 690 min. ÷ 230 min. = 3 times
The bacteria wil<u>l double its colony 3 times in 690 minutes</u>.
- <em>First division:</em> 100 x 2 = 200 bacteria
- <em>Second division:</em> 200 x 2 = 400 bacteria
- <em>Third division:</em> 400 x 2 = 800 bacteria
Therefore, the population of bacteria will be 800 in 690 minutes.
Keep in mind that means is the same as asking for the average. all you need to do is add all the values and divide them by the number of values, which is 5
