A) Fill in the blanks to show what the next three numbers are in the following sequence. 28 , 37 , 46 , 55 , 64 ,
,
,

b) Is the sequence arithmetic, geometric or neither?

a) 73, 82, 91

b) arithmetic

Step-by-step explanation:

a) We add 9 after each term, making the common difference 9.

As such, 64 + 9 = 73

73 + 9 = 82

82 + 9 = 91

b) This sequence is arithmetic because it has a common difference, if it had a common ratio, it would be geometric.

3; 9 is 8 to -4

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
