Answer:
b(x) = -2X² + 19X + 114
Step-by-step explanation:
b(x) = total revenue generated per day
total revenue formula ⇒ b(x) = price x quantity
price = $3 current price + 0.5X price increase = 3 + 0.5X
quantity = 38 current quantity sold - 4 books per X = 38 - 4X
b(x) = (3 + 0.5X) · (38 - 4X)
b(x) = 114 -12X + 19X - 2X²
b(x) = -2X² + 19X + 114
Use pi•r^2 for the formula of a circle. filling it in, you get 3.14•64 which is 200.96
Answer:
Prime
Step-by-step explanation:
- As there is no common between 5y and 7 except 1 as factor.
- Hence its not factorable
Answer:

Step-by-step explanation:
The general exponential function is,

The points given in the table are,

Putting
in the general equation, we get


And


Putting the value of a,


Now the exponential function becomes,

Lim x->1 (x^2+8x-2)
substitute x =1
= 1^2 +8(1)-2
= 1 +8 -2
= 7
So the limit = 7
