Answer:

Step-by-step explanation:

If n = 1 , a1 = 9^1^2 +3 = 12

a2 = 9*2^2 + 3 = 39

a3 = 9*3^2 + 3 = 84

The differences are 39 - 12 = 27 and 84 - 39 = 45 so it is not arithmetic as an arithmetic series ad a common difference.

Answer: C

Step-by-step explanation:

This describes an expotential function

At t = 0, P = 70

Therefore, C = 70

P = 70 e^kt

Solve for k by plugging in (4,360)

k = 0.4094

plug in t(7 hours)

70 e^(0.4094*7)

The answer roughly equals C

lbvjy [14]

$ 325.2372 will be charged on Patrick's Visa card.

Explanation

The regular price of each tire is $95.99 and the discount amount is $20 per tire.

So, the selling price of each tire will be: $(95.99-20)dollar=75.99 dollar$

and the total selling price of 4 tires $= (75.99*4)dollar=303.96 dollar$

The sale tax is 7%. So, the amount of sale tax $= 7\% of 303.96 = (0.07*303.96)dollar = 21.2772$ dollar

So, the total charge on Patrick's Visa card will be: $(303.96+21.2772)dollar = 325.2372$ dollar
