1. Separate the number 58 into three parts so
Anika [276]

Answer:

2nd number = 13

First number = 15

3rd number = 30

Step-by-step explanation:

Let

2nd number = 1/2x - 2

First number = 1/2x

3rd number = x

Total = 58

x + 1/2x + 1/2x - 2 = 58

x + x+x/2 = 58 + 2

x + 2/2x = 60

x + x = 60

2x = 60

x = 60/2

= 30

x = 30

2nd number = 1/2x - 2

= 1/2*30 - 2

= 15 - 2

= 13

First number = 1/2x

= 1/2*30

= 15

3rd number = x

= 30

Alabama Instruments Company has set up a production line to manufacture a new calculator. The rate of production of these calcul
anyanavicka [17]

Answer:

5536 calculators

Step-by-step explanation:

We integrate the function dx/dt to obtain the number of new calculators between beginning of the 3rd week  and end of week 4. Note that beginning of 3rd week is the same as end of 2nd week. So, \int\limits^4_2 {\frac{dx}{dt} } \, dx=  \int\limits^4_2 {5000 (1 - \frac{100}{(t +12)^{2} }) } \, dx

Let u = t + 12, then \frac{du}{dt}= 1. So, du = dt. We also change the limits of our integration. So, when t = 2, u = 2 + 12 = 14 and when t = 4, u = 4 + 12 = 16

Then  \int\limits^4_2 {5000(1 -\frac{100}{(t+12)^{2} } )} \, dx = ∫₁₄¹⁶ {5000(1 -\frac{100}{u^{2} } )} \, du = 5000[ u + \frac{100}{u} ]₁₄¹⁶ = 5000[16 + \frac{100}{16} - (14 + \frac{100}{14} )] = 5000 [16 - 14 + \frac{100}{16} - \frac{100}{14}  ] = 5000 [2 + \frac{100}{16} - \frac{100}{14}  ] = 5535.7

≈ 5536 calculators
