Alborosie

Answer:

a) d = 3 b) a(n) = 3n – 13 c) a(27) = 68

Step-by-step explanation:

solutions are (x, y) = (29,13) and (9349, 4181), which lead to (a, b) = (15,5) and (4895 ... corresponding to integer values of x give the quadruples. (x, y, z ... Since no number congruent to 3, modulo 4, can be written as the sum of two squares ... k is odd, the equation x2 - (k2 - 4)y2 = 4 has smallest solution in positive integers .

What are the missing lengths ???

lesantik [10]

Answer:

1. c = 13

2. a = 20

Step-by-step explanation:

1. 12² + 5² = x²

144 + 25 = x

144 + 25 = 169

√169 = 13

2. 29² - 21² = x²

841 - 441 = x

841 - 441 = 400

√400 = 20

Newton’s Law of Cooling expresses the relationship between the temperature of a cooling object y and the time t elapsed since co

True [87]

Answer:

79 °F

Step-by-step explanation:

Newton’s Law of Cooling:

$y = ae^{-kt} + c$

Data

The initial temperature of a liquid is 160 °F

The temperature in the room (c) is 76 °F

Then a = 160 - 76 = 84 °F

k = 0.23

t = 15 minutes

Replacing into the equation:

$y = 84e^{-0.23 \times 15} + 76$

y = 79 °F
