Answer: a) $33.98, b) $2245.05

Step-by-step explanation:

Since we have given that

Revenue function is given by

R(x)=\dfrac{68x^2+76}{2x+2}

On simplifying, we get that

R(x)=\dfrac{34x^2+38}{x+1}

If the number of units sold = 65

We need to find the Marginal revenue.

Revenue at 65 units would be

\dfrac{34(65)^2+38}{65+1}=\$2177.09

Revenue at 66 units would be

\dfrac{34(66)^2+38}{66+1}=\$2211.07

So, marginal revenue would be

2211.07-2177.09\\\\=\$33.98

Projected revenue from the sale of 66 units would be

2211.07+33.98\\\\=\$2245.05  

Hence, a) $33.98, b) $2245.05

Answer:

93°

Step-by-step explanation:

By exterior angle theorem:

(4x + 9)° = 2x° + (3x - 12)°

(4x + 9)° = (2x + 3x - 12)°

(4x + 9)° = (5x - 12)°

4x + 9 = 5x - 12

4x - 5x = - 12 - 9

-x = - 21

x = 21

Measure of exterior angle

= (4x + 9)°

= (4*21 + 9)°

= (84 + 9)°

= 93°
