Answer:
Total revenue = 
dollars
Step-by-step explanation:
Integrate with respect to 
.
∫
dx
Take 
Differentiate with respect to
So,
∫
Use integration by parts: ∫f g dx = f∫ g dx-∫(∫g dx)f' dx
Therefore,
∫
= ∫
Put 
To find total revenue from the sale of the first 12 calculators, put 
Total revenue = dollars
Answer:
D
Step-by-step explanation:
All real number less than 5
The answer is:
6 = 9x + 27
depending on what you are supposed to do.
You are given that PS ≅ RS as indicated by the single has mark.
You are given that ∠PST ≅ ∠RST as indicated by the single arc.
You know the segment ST is congruent to itself by the reflexive property.
That is, you have two congruent sides and the angle between them, so you can claim the triangles are congruent by the SAS postulate.
Selection C is appropriate.
You can solve for sides of a triangle using the following equation.
A = arccos (b^2 + c^2 - a^2/2bc)
And likewise for other variables by moving the letters.
Ultimately, in this problem you get the following angle measures:
15.87
23.97
140.16
