You need to buy a new cell phone now and are trying to minimize your cell phone costs for the next 5 years. A new cell phone cos

ts C dollars and lasts for at most 3 years. The estimated maintenance cost for a phone depends on its age; if a phone is in its ith year of life, the cost will be M_i dollars, i = 1, 2, 3. Assuming cell phones have no salvage value and that you have the option each year of buying a new phone (for C dollars), formulate a network model that will minimize your costs over the next 5 years.

In the theory of learning, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to
fiasKO [112]

Step-by-step explanation:

From the statement:

M: is total to be memorized

A(t): the amount memorized.

The key issue is translate this statement as equation "rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized"

memorizing rate is \frac{dA(t)}{dt}.

the amount that is left to be memorized can be expressed as the total minus the amount memorized, that is M-A(t).

So we can write

\frac{dA(t)}{dt}=k(M-A(t))

And that would be the differential equation for A(t).

You are planning a skating party at a rink that charges a basic fee of $6.00 and $6.50 per person for catered parties. You don’t
Alekssandra [29.7K]

Answer:

y = 6.50x + 6 or 71 = 6.50x + 6

10 people are the max you can invite

Step-by-step explanation:

We have the simple equation

y = 6.50x + 6

6.50x because it it per person

6 because it is a flat one time charge

We want the max to be 71 so that will be our y

71 = 6.50x + 6

We are now going to solve for x

65 = 6.5x

x = 10

Hope it helps! (:

13. What is the surface area of the rectangular solid below using its net?
loris [4]

<u><em>Answer:</em></u>

108 square units

<h3><u><em>Step-by-step explanation:</em></u></h3>

3 x 4 = 12

3 x 4 = 12

6 x 3 = 18

6 x 3 = 18

6 x 4 = 24

6 x 4 = 24

24(2) + 18(2) + 12(2) = 108 square units

Therefore, the surface area of the rectangular solid below using its net is <u>108 square units</u>

TEA [102]

Answer:

m<1 = 69°

Step-by-step explanation:

Angles 20x + 11 and 25x - 14 are vertical angles, so they are congruent.

25x - 14 = 20x + 11

5x = 25

x = 5

The actual measure of angle 20x + 11 is 20(5) + 11 = 111°.

Angle 20x + 11 and <1 are supplementary, so the sum of their measures is 180°.

m<1 + 111° = 180°

m<1 = 180° - 111°

m<1 = 69°
