Answer:
8 x 10^14 is 800000000000000, and 2 x 10^9 is 2000000000 so 8 x 10^4 is 400000 greater, Good Luck!
Step-by-step explanation:
Answer:
a). f(0) = 4
b). f(6) = 8
Step-by-step explanation:
a). When x < 5, piecewise function to be considered,
f(x) = x + 4
Since, x = 0 is less than x = 5
f(0) = 0 + 4
f(0) = 4
b). When 5 ≤ x < 7,
Piecewise function to be considered,
f(x) = 8
Therefore, for x = 6,
f(6) = 8
The customer will pay $3.57 for the greeting card
Explanation:
The card originally costs $4 before tax and is discounted by 15%
0.15 x 4 = 0.6
4 - 0.6 = 3.4
Then the 5% sales tax is added:
0.05 x 3.4 = 0.17
3.4 + 0.17 = 3.57
