Answer:
g^-1 (x) = x+3/2
Step-by-step explanation:
To find the inverse function, interchange x and y and then solve for y
y = x-3/2
Interchange x and y
x = y -3/2
Add 3/2 to each side
x+3/2 =y-3/2+3/2
x+3/2 =y
g^-1 (x) = x+3/2
Answer:
= 5
Step-by-step explanation:
The recursive rule for a geometric sequence is
= a
where a is the first term and r the common ration
Here
r = - 10 ÷ 5 = 20 ÷ - 10 = - 2 and a = 5, thus
= 5
Company A: y=20x+40
Company B: y=25x+20
Answer:
Average cost per ball: $22.2
Step-by-step explanation:
Cost per ball: $22
Cost of 300 balls: 300 × 22 = $6600
Total No. of Orders: 3
Delivery fee per order: $20
Total Delievery fee: 20 × 3 =$60
Total cost including delivery cost: $6600 + $60 = $6660
