Find the area enclosed by the curve x 3t, y t and the y-axis. Step 1 The curve x = t2-3t, y = Vt intersects the y-axis when x = 0, which occurs when t = 0 and 3 3 H 3 '
The area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis is 2.08 square units.
We have been given parametric equations x = t^2 − 3t, y = √t
We need to find the area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis.
Consider x = 0
So, t^2 − 3t = 0
t(t - 3) = 0
t = 0 or t = 3
Let f(t) = t^2 − 3t and g(t) = t
Differentiate the curve f(t) with respect to t.
f'(t) = 2t - 3
NWe know that the formula to find the area under the curve.
A = ∫[a to b] g(t)f'(t) dt
here, a = 0 and b = 3
so, A = ∫[0 to 3] √t (2t - 3) dt
A = ∫[0 to 3] (2t√t - 3√t) dt
A = ∫[0 to 3] (2t^(3/2) - 3t^(1/2)) dt
A = [4/5 t^(5/2) - 2 t^(3/2)]_[t = 0, t = 3]
A = 4/5 3^(5/2) - 2 3^(3/2) - 0 + 0
A = 4/5 3^(5/2) - 2 3^(3/2)
A = 6√3 /5
A = 2.08
Therefore, the area of the curve is 2.08 square units.

The integral with respect to time of a force applied to an object is a measure called impulse, and the impulse applied to an object during a time interval determines its change in momentum during the time interval. The safety of a t-shirt launcher, used to help get crowds cheering at baseball games, is being evaluated. As a first step in the evaluation, engineers consider the design momentum of the launched t-shirts. The springs in the launcher are designed to apply a variable force to a t-shirt over a time interval of t1 = 0.5 s. The force as a function of time is given by F(t) = ať+ b, where a = –28 N/s2 and b = 7.0 N. The momentum of the t-shirt will be its initial momentum (po 0) plus its change in momentum due to the applied impulse: pf = po+SET+ F(t) dt. By applying the given time dependent function for F(t) and performing the integration, which of the following is the correct expression for Pf? ► View Available Hint(s) tl tl Pf= 0++)16 0+*+*+b) 0+++bt) 0++) ti Correct: We check that we have obtained the correct form of the integral by performing differentiation of gte + bt with respect to t, which gives at +6= F(t) as expected. Part B The units of the momentum of the t-shirt are the units of the integral si ti F(t) dt, where F(t) has units of N and t has units of S. Given that 1 N=1 kg. m/s",the units of momentum are: ► View Available Hint(s) - kg/s - kg.m/s3 - kg.m/s - kg•m/s2 Correct: The units of a quantity obtained by integration will be the units of the integrand times the units of the differential. Part C Evaluate the numerical value of the final momentum of the t-shirt using the results from Parts A and B.
► View Available Hint(s) kg.m Pf = 2.3 S
Part A: To find the expression for Pf, we need to integrate F(t) with respect to t over the given time interval.
Given that F(t) = ať + b, where a = -28 N/s^2 and b = 7.0 N, the integral can be calculated as follows:
Pf = po + ∫(F(t) dt)
Pf = po + ∫(ať + b) dt
Pf = po + ∫(ať dt) + ∫(b dt)
Pf = po + (1/2)at^2 + bt + C
Therefore, the correct expression for Pf is:
Pf = po + (1/2)at^2 + bt + C
Part B: The units of momentum can be determined by analyzing the units of the integral. Since F(t) has units of N (newtons) and t has units of s (seconds), the units of the integral will be N * s. Given that 1 N = 1 kg * m/s^2, the units of momentum are kg * m/s.
Therefore, the correct units of momentum are kg * m/s.
Part C: To evaluate the numerical value of the final momentum (Pf), we need to substitute the given values into the expression obtained in Part A. However, the initial momentum (po) and the time interval (t) are not provided in the question. Without these values, it is not possible to calculate the numerical value of Pf.

as part of video game, the point (5,2) is rotated counterclockwise about the origin through an angle of 5 degrees. find the new coordinates of this point
The new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees are approximately (4.993, 2.048).
To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:
x' = x * cos(theta) - y * sin(theta)
y' = x * sin(theta) + y * cos(theta)
Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.
Converting the angle of rotation from degrees to radians:
theta = 5 degrees * (pi/180) ≈ 0.08727 radians
Plugging in the values into the rotation formula:
x' = 5 * cos(0.08727) - 2 * sin(0.08727)
y' = 5 * sin(0.08727) + 2 * cos(0.08727)
Evaluating the trigonometric functions and simplifying:
x' ≈ 4.993
y' ≈ 2.048

Let f:R−{n}→R be a function defined by f(x)= x−n
x−m
R, where m
=n. Then____
The domain of the function is R - {m} and the range of the function is (-∞, ∞).
We are given a function f: R−{n}→R defined by f(x) = (x-n)/(x-m), where m ≠ n.
To find the domain of the function, we need to consider the values of x for which the denominator (x-m) is zero. Since m ≠ n, we have m - n ≠ 0, and therefore the function is defined for all x except x = m.
Therefore, the domain of the function is R - {m}.
To find the range of the function, we can consider the behavior of the function as x approaches infinity and negative infinity. As x approaches infinity, the numerator (x-n) grows without bound, while the denominator (x-m) also grows without bound, but at a slower rate. Therefore, the function approaches positive infinity.
Similarly, as x approaches negative infinity, the numerator (x-n) becomes very negative, while the denominator (x-m) also becomes very negative, but at a slower rate. Therefore, the function approaches negative infinity.
Thus, we can conclude that the range of the function is (-∞, ∞).
In summary, the domain of the function is R - {m} and the range of the function is (-∞, ∞).

The age of the decaying sample according to the decay formula is 42,009 years.
The rate of radioactive carbon-14 decay depends on the function
\(A(t) = A_{0} e^{-0.0001216t}\)
where \(A_{0}\) is the quantity found in living plants and animals, t is in years, and is the age.
60% of the carbon-14 of a current-day sample was present in a sample taken from a refuse deposit close to the Strait of Magellan. We need to evaluate the age of the sample,
A = 60 % of \(A_{0}\) = (3/5)\(A_{0}\)
Putting this in the decay equation, we have,
\(\frac{3}{5} A_{0} = A_{0} e^{-0.0001216t}\\\\ 0.6= e^{-0.0001216t}\\ \\ln0.6 = -0.00001216t\\\\-0.51082 = -0.00001216t\\\\t = 42,008.68\)

How to explain the steps?Take for instance, we have the function to be
Function f(x)
And the interval is (a,b)
The average rate of change for the function over the interval is
Rate = (f(b) - f(a))/(b - a)
The above represents the slope
Take for instance, we have:
f(x) = x^2 [2, 4]
We have:
f(2) = 2^2 = 4
f(4) = 4^2 = 16

What are Exponential Functions?Exponential functions are those functions where the independent variable, x is in the exponent.
Given exponential function is,
f(t) = \(a . b^t\)
The exponential function can be written as,
f(t) = \(a(1+r)^t\), where r is the rate of increase or decrease.
So, b = 1+ r
It is given that the population is increasing, so rate is positive.
So b = 1 + r, is greater than 1.
Average rate of change of a function is the ratio change in function values to the change in t values.
Change in t is same as we are measuring over 5 years.
Since the function is increasing at a constant rate, the function values will also be outgoing a large increase as the time increases.
So the average rate of change from year 0 to year 5 is less than the average rate of change from year 10 to year 15.
a is the initial population of the deer when t = 0. This must be greater than 0.

The outward flux of the field F across the cube is equal to 3a⁵ / 2.
Given that field F=6xyi+8yzj+6xzk and the surface of the cube is cut from the first octant by the planes x = a, y = a, z = a. We need to find the outward flux of the given field across the surface of the cube.
To find the outward flux of the field F,
we have to use the Gauss Divergence theorem, which states that,
The outward flux of a vector field F through a closed surface S is equal to the volume integral of the divergence of the vector field over the volume V enclosed by that surface,
mathematically we can write it as,∫∫F⋅dS = ∫∫∫ V (∇⋅F) dVWhere F is the vector field, S is the closed surface, V is the volume enclosed by that surface, ∇ is the divergence operator, and ⋅ is the dot product of two vectors.
Let's solve the given problem; here, the cube is cut from the first octant by the planes x = a, y = a, z = a.
Therefore, the planes which cut the first octant is given as shown below:
Thus, a cube is formed from these three planes, as shown below
:Now, the volume enclosed by this cube is a^3,
thus we can rewrite the above formula as,∫∫F⋅dS = ∫∫∫ V (∇⋅F) dV = ∫∫∫ V (6x + 8y + 6z) dV
Now, we have to solve the above volume integral using the given limits.
Limits are 0 to a for x, 0 to a for y, and 0 to a for z.
∫∫F⋅dS = ∫∫∫ V (6x + 8y + 6z) dV
= ∫0a ∫0a ∫0a (6x + 8y + 6z) dz dy dx
= ∫0a ∫0a [(3a²y + 3a²)] dy
= 3a⁵ / 2
The outward flux of the field F across the cube is equal to 3a⁵ / 2.
