Answer:

i had this question before

Step-by-step explanation:

c^2=a^2+b^2-2abcos(c)

c=sqrt(a^2+b^2-2abcos(c))

c=sqrt((5)^2+(12)^2-2(5)(12)cos(72))

c=sqrt(25+144-120cos(72))

c=sqrt(169-120cos(72))

c=sqrt(169-37.08)

c=sqrt(131.92)

c=11.49

Graph the first six terms of a sequence where a1=5 and r=1.25

emmainna [20.7K]

The sequence above is geometric progression.
The nth term of such sequence is given by;

Tn = ar∧(n-1),
Where a⇒first term and
r⇒common ratio

So, 1st term = 5×1.25∧(1-1) = 5×1.25∧0 =5
2nd term = 5×1.25∧(2-1) = 5×1.25 = 6.25
3rd term = 5×1.25∧(3-1) = 5×1.25² = 7.8125
4th term = 5×1.25∧(4-1) =5×1.25³ = 9.765625
5th term = 5×1.25∧(5-1) = 5×1.25∧4 = 12.20703125
6th term = 5×1.25∧(6-1) = 5×1.25∧5 = 15.25878909

A company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce e

olasank [31]

Answer:

C(x) = 0.1x+23000

Step-by-step explanation:

Given that a company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce each doughnut. The company sells each doughnut for $0.2.

Let X be the no of units produced

Then we have variable cost = 0.1x

Fixed cost = 23000 (irrespective of value of x)

Total cost

$C(x) = 0.1x+23000$
