We have
x(t) = t³ ⇒ dx/dt = 3t²
y(t) = t ⇒ dy/dt = 1
so that the line element is
ds = √((dx/dt)² + (dy/dt)²) dt = √(9t⁴ + 1) dt
and the line integral is
[tex]\displaystyle \int_C y^3 \, ds = \int_0^5 t^3 \sqrt{9t^4 + 1} \, dt[/tex]
Substitute u = 9t⁴ + 1 and du = 36t³ dt :
[tex]\displaystyle \int_C y^3 \, ds = \frac1{36} \int_1^{5626} \sqrt u \, du = \frac1{36} \cdot \frac23 \left((5626^{\frac32} - 1^{\frac32}\right) = \boxed{\frac{5626^{\frac32} - 1}{54}}[/tex]

f^-1(x)=1/5x
Explanation:
[tex]f^{-1}(x) = -\frac 15x[/tex] is reflected across the x-axis to form [tex]f^{-1}(x) = \frac 15x[/tex].
The function is given as:
[tex]f^{-1}(x) = -\frac 15x[/tex]
[tex]f^{-1}(x) = \frac 15x[/tex]
By comparison, we can see that:
Both functions are inverse functionsBoth inverse functions hold different valuesRewrite the second function as:
[tex]g^{-1}(x) = \frac 15x[/tex]
So, the relationship between both inverse functions is:
[tex]f^{-1}(x) = -g^{-1}(x)[/tex]
The above relationship means that, f'(x) is reflected across the x-axis to form g'(x)
Hence, [tex]f^{-1}(x) = -\frac 15x[/tex] is reflected across the x-axis to form [tex]f^{-1}(x) = \frac 15x[/tex].

Which quotation from this passage is an example of foreshadowing? "Some hams hanging in the kitchen were taken out for burial, and the barrel of beer in the scullery was stove in." "The farmhouse should be preserved as a museum. All were agreed that no animal must ever live there." "The animals had their breakfast, and then Snowball and Napoleon called them together again." "‘Comrades,’ said Snowball, ‘it is half-past six. . . . Today we begin the hay harvest.’"
Answer:
B) “The farmhouse should be preserved as a museum. All were agreed that no animal must ever live there.”
Explanation:
I did the quiz
When we look at the house through the eyes of the animals, we find it amusing that the hams were buried, but the animals see it as completely appropriate. At this point, every animal on the farm is participating in decision-making, and they all agree to retain the farmhouse as a museum. Thus, option B is correct.
What quotation from is an example of foreshadowing?The farmhouse should be kept as a museum, it was decided unanimously there and then. Everyone concurred that no animal should ever reside there. Following breakfast, Snowball and Napoleon called the animals back together.
They Jones and his men had never witnessed animal behaviour like this before, and the sudden revolt of the creatures, which they were accustomed to whipping and torturing as they pleased, scared them nearly to the point of insanity.
Therefore, “The farmhouse should be preserved as a museum. All were agreed that no animal must ever live there.”

According to the equation for the reaction, if the amount of the reactants is halved, how does this affect the amount of h2o(l) produced in the reaction?.
Answer:
Explanation:
According to the reaction equation shown, if the amount of the reactants is halved, the amount of H2O(l) produced in the reaction will be halved.
The molecular reaction equation was given as follows; HCl(aq) + NaOH(aq)→ NaCl(aq) + H2O(l). Ionically, we can write; H^+(aq) + Cl^-(aq) + Na^+(aq) + OH^-(aq) ----> Na^+(aq) + + Cl^-(aq) + H2O(l). The net ionic equation now becomes; H^+(aq) + OH^-(aq) ----> H2O(l).
This implies that the concentration of H2O(l) depends on the concentrations of H^+(aq) and OH^-(aq) from HCl(aq) and NaOH(aq) respectively and the mole ratio of reactants and products is 1:1:1:1.
Hence, of the amount of the reactants is halved, the amount of H2O(l) produced in the reaction will be halved.
