Natalie picked 135 berries in 15 minutes. If she continues picking at that rate, how many total minutes will it take her to pick
Alex777 [14]
Lets focus on what we know first. Natalie can pick 135 Berries in 15 minutes. Lets find out how many berries she can pick per minute.
In order to do so, We have to divide 135 by 15.

135/15=9
This means that Natalie can pick 9 berries per minute. Given that we want her to pick 486, we will need to divide that number by 9 berries to find out how many minutes it will take to get her to that number of berries.

486/9=54

This means that it will take Natalie 54 minutes in order to pick 486 berries.

Answer:

.79 mm^2

Step-by-step explanation:

First find the area of the circle

A = pi r^2

A = 3.14 (1) ^2

A = 3.14

Now we have 1/4 of the circle

The area is 1/4 of the full area

1/4 *3.14

.785

Rounding to the nearest hundredth

Find, if it exists, a value c in the interval [1, 4] such that the instantaneous rate of change of f(x) = 12<img src="https://te
ella [17]

Answer:

  c = 2.25

Step-by-step explanation:

f(x) is a continuous and differentiable function on the interval, so the Mean Value Theorem guarantees a value for c exists.

The average slope is ...

  m = (f(4) -f(1))/(4 -1) = (24 -12)/3 = 4

The point at which the derivative is 4 is ...

  f'(c) = 6/√c = 4

  √c = 6/4

  c = 2.25
