The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
<u>Solution:</u>
Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.
The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.
If you wish to rent the canoe from 12:30 to 3:30 PM,
We have to write and solve a linear equation to find the total cost to rent the canoe.
Now, we know that,
<em>total cost = charges + rent fee </em>
Let total cost be "c" and number of hours rented be "n"
Now, they used canoe from 12:30 to 3:30, which means 3 hours of time
So, put n = 3 in (1)
c = 6.5(3) + 25
c = 19.5 + 25
c = 43.5
Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
Answer:
Area = 32/3
Step-by-step explanation:
x = u ²
y = uv
z = 12v ²
0 ≤ u ≤ 2
0 ≤ v ≤ 1
Since ru = <2u, v, 0> and rv = <0, u, 24v>, we have
Where ru is the differentiation of x, y, z with respect to u and rv is the differentiation of x, y, z wit respect to v.
we find the cross product of ru and rv
ru × rv = 24v²i - 48uv²j + 2u²k
absolute value of ru × rv = 2u² + 24v²
We can now find the area
∫₀² du ∫₀¹ dv (2u² + 24v²) = ∫₀² du [2u²v + 8v³]₀¹ = 32/3
