Answer:
x^4 + 4x^3 + 6x^2 + 7x +2
Step-by-step explanation:
x^2 x x^2 = x^4
x^2 x x = x^3
x^2 x 2 = 2x^2
3x x x^2 = 3x^3
3x x x = 3x^2
3x x 2 = 6x
1 x x^2 = x^2
1 x x = x
1 x 2= 2
x^4 + 4x^3 + 6x^2 + 7x +2
Coffee = $12
Tea = $8
Total cost = $2600
Total Case = 250
Assumed all 250 cases are Tea
250 x 8 = 2000
Difference in amount
2600 - 2000 = 600 (so $600 was from the coffee)
Difference between the price of coffee and tea
12 - 8 = $4
Number of cases of coffee
600 ÷ 4 = 150
Number of cases of tea
250 - 150 = 100
150 cases of coffee were ordered
: Let y = f(x) = x^1/3
Then dy = 1/3*x^(−2/3) dx
Since f(64) = 4.
We take x = 64 and dx = ∆x = 1
This gives dy = 1/3*(64)^(−2/3)* (1) = 1/48
∴65^(1/3) = f(64 + 1) ≈ f(64) + dy = 4 + 1/48 ≈ 4.021 <span>
