Nia increased her class average by 3%. She now has a 92% in her math class.
Answers
Nia's original class average was 89%. After increasing it by 3%, she now has a 92% in her math class.
1. Let's assume Nia's original class average was X.
2. She increased her class average by 3%, which can be represented as X + (3/100)X.
3. According to the question, X + (3/100)X = 92.
4. Simplifying the equation, we have (103/100)X = 92.
5. To find X, we divide both sides of the equation by (103/100): X = (92 * 100) / 103.
6. Calculating the value, X ≈ 89.32.
7. Therefore, Nia's original class average was approximately 89.32%.
8. After increasing it by 3%, her new class average is 89.32% + (3/100) * 89.32% ≈ 92%.

Let D be the region enclosed by the two paraboloids z = 3x2 + + y2 z = 16 – x2 Then the projection of D on the xy-plane is: 2 *-* = 1 = 1 16 = 1 4 16 O This option O This option x None of these 16 4
Answers
The projection of the region D onto the xy-plane is an ellipse centered at the origin, with a major axis length of 4 and a minor axis length of 2.
To find the projection of the region D onto the xy-plane, we need to determine the intersection curve of the two paraboloids in the xyz-space. Setting the equations of the paraboloids equal to each other, we have:
3x^2 + y^2 = 16 - x^2.
Combining like terms, we get:
4x^2 + y^2 = 16.
This equation represents an ellipse in the xy-plane. To visualize the projection, let's rewrite the equation in terms of standard form:
(x^2)/4 + (y^2)/16 = 1.
Comparing this equation to the standard equation of an ellipse, (x^2)/(a^2) + (y^2)/(b^2) = 1, we can see that the major axis of the ellipse is along the y-axis, with a length of 4, and the minor axis is along the x-axis, with a length of 2.
Therefore, the projection of the region D onto the xy-plane is an ellipse centered at the origin, with a major axis length of 4 and a minor axis length of 2. The shape of the ellipse will have its major axis along the y-axis and its minor axis along the x-axis.
In summary, the projection of the region D onto the xy-plane is an ellipse centered at the origin, with a major axis length of 4 and a minor axis length of 2.

Andre will agree as he thinks that the no. of paper clips in the box is less than 1000. But lin will not as she thinks that the no. of clips is more than 500.
4)This time, they both will agree as the no. of paper clips is more than 500 but less than 1000.
So that means, the answer is p < 1000
For number 2, it’s asking for the same thing. Lin says that it needs to be more than 500.
So that means, the answer is p > 500
For number 3, it’s just asking you if the number “487” is reasonable. You find that by plugging in the number 487 into “p”.
Is 487 < 1000 correct? Yes!
Is 487 > 500 correct? NO!
So that means for number three, you should put, “Lin and Andre would not agree. This is because the number 487 fits with Andre’s statement, but it does not fit with Lin’s. 487 is less than 1000, but it is not greater than 500.”
For number 4, you do the same thing. Plug in 742 into “p”.
Is 742 < 1000? Yes!
Is 742 > 1000? Yes!
So that means for number 4, you should put, “Lin and Andre would agree. This is because the number 742 fits with Andre’s and Lin’s statement. 742 is less than 1000, and it is greater than 500.”
If the measure of arc KM is 112°, find the measure of arc LM
Answers
All circles are equal to 380 degrees
You’re alr told that a part of the circle is equal to 112
So you subtract 360-112 which is 248
This means that the rest of the circle (without the zone that KM covers) is 248
As you can see both sides (ML and KL) are equal because they have congruency lines
So both sides have the exact same length
If what’s remaining is 248 and there are 2 equal sides you just have to divide
248/2 and that is 124

(a) what is the effect on the period of a pendulum if you double its length?
Answers
If we double the length of the pendulum, the period of the pendulum will be approximately 1.4 times longer than it was before. This relationship between the length and period of a pendulum is very important, as it allows us to calculate the length of a pendulum needed to produce a desired period. This relationship is also used in many applications, such as clocks and metronomes.
The period of a pendulum is the time it takes to swing back and forth through one complete cycle. The period of a pendulum is affected by the length of the pendulum, the acceleration due to gravity, and the amplitude of the swing. If the length of a pendulum is doubled, the period of the pendulum will also double. The reason for this is that the period of a pendulum is directly proportional to the square root of its length.
This means that if the length of the pendulum is increased by a factor of 2, the period of the pendulum will increase by a factor of sqrt(2).
Mathematically, this can be expressed as: T = 2π * sqrt(L/g).
Where T is the period of the pendulum, L is the length of the pendulum, and g is the acceleration due to gravity.
If we double the length of the pendulum (L), the equation becomes T = 2π * sqrt(2L/g).
Taking the ratio of the new period to the original period, we get: T_new/T_old = sqrt(2).
Therefore if we double the length of the pendulum, the period of the pendulum will be approximately 1.4 times longer than it was before. This relationship between the length and period of a pendulum is very important, as it allows us to calculate the length of a pendulum needed to produce a desired period. This relationship is also used in many applications, such as clocks and metronomes.

Answers
(a) Not of exponential order.
(b) Not of exponential order.
(c) Exponential order with c = 2.
(d) Not of exponential order.
(e) Not of exponential order.
To determine if a function is of exponential order, we need to check if there exist positive constants M and c such that |y(t)| ≤ M[tex]e^{ct}[/tex] for all t ≥ t₀, where t0 is some starting point.
Let's analyze each function:
(a) y(t) = 5t² + 24 + 1
This function is not of exponential order since it contains a quadratic term (t²) and does not satisfy the exponential order condition.
(b) y(t) = sin(3t)
The sine function is periodic and oscillates between -1 and 1. It is not bounded by an exponential function. Therefore, it is not of exponential order.
(c) y(t) = 4[tex]e^{2t}[/tex]
The exponential function [tex]e^{2t}[/tex] grows exponentially as t increases. The constant multiplier 4 does not affect the exponential growth. Therefore, this function is of exponential order with c = 2.
(d) y(t) = [tex]e^{t^{2} }[/tex]
The exponent t² grows faster than any exponential function with a constant base. Therefore, this function is not of exponential order.
(e) y(t) = cost [tex]e^{3t}[/tex]
The exponential function [tex]e^{3t}[/tex] grows exponentially as t increases. However, the cosine function oscillates between -1 and 1, which prevents the overall function from being bounded by an exponential function. Therefore, it is not of exponential order.

Evaluate the work done between point 1 and point 2 for the conservative field F.
F = 6x i + 6y j + 6z k; P 1(4, 3, 5) , P 2(5, 6, 7)
a)W = - 180
b)W = 480
c)W = 0
d)W = 180
Answers
The correct answer is option (c) W = 0.
Given information :F = 6xi + 6yj + 6zk; P1(4, 3, 5), P2(5, 6, 7)The formula for work done by the conservative force is given by: W = U(P2) - U(P1)Where U(P) is the potential energy at point P. The force is conservative. Hence, work done is independent of path and is equal to the difference in potential energy between points 1 and 2.To find the potential energy U at any point, we use the formula: U(x, y, z) = - ∫F.dr where F is the force, and dr is the infinitesimal displacement vector.
To find the potential difference between two points, we integrate the formula: W = - ∫F.dr over a path between those two points, P1 and P2.Now we will find the potential energy at points 1 and 2.∴U(P1) = -∫F.drbetween the limits (4,3,5) and (5,6,7)Let us take the path from P1 to P2 along the straight line. Then the position vector of the path is:r = (5 - 4) i + (6 - 3) j + (7 - 5) k = i + 3j + 2k.dr = dx i + dy j + dz k= i dx + j dy + k dz = i dt + 3j dt + 2k dt = (i + 3j + 2k) dt∴∫F.dr= ∫6x i . (i + 3j + 2k) dt + ∫6y j . (i + 3j + 2k) dt + ∫6z k . (i + 3j + 2k) dt= ∫6x dt + 3 * 6y dt + 2 * 6z dt= (6x + 18y + 12z) |_P1^P2= (6 * 5 + 18 * 6 + 12 * 7) - (6 * 4 + 18 * 3 + 12 * 5)= 30 + 108 + 84 - 24 - 54 - 60= 84Thus, U(P2) - U(P1) = 0 - 84 = -84. Hence, work done = -(-84) = 84Option (d) W = 180 is incorrect as the value of work done is 84.

The statement "W is a subspace of P2" is true, as W satisfies the conditions for being a subspace: closure under addition and scalar multiplication, and containing the zero vector.
The statement "W is a subspace of P2" is true.
To show that W is a subspace, we need to verify the three conditions for subspace:
W is closed under addition: For any two polynomials p(x) = a + 2x + bx^2 and q(x) = c + 2x + dx^2 in W, their sum p(x) + q(x) = (a + c) + 4x + (b + d)x^2 is also in W. Therefore, W is closed under addition.
W is closed under scalar multiplication: For any polynomial p(x) = a + 2x + bx^2 in W and any scalar k, the scalar multiple kp(x) = ka + 2kx + kbx^2 is also in W. Therefore, W is closed under scalar multiplication.
W contains the zero vector: The zero polynomial 0 = 0 + 0x + 0x^2 is in W since a = b = 0. Therefore, W contains the zero vector.
Since W satisfies all three conditions for subspace, it is indeed a subspace of P2.
Hence, the statement "W is a subspace of P2" is true.

Let y+3=xy-6x². Use implicit differentiation to find y' or dy dx
Answers
the derivative of y with respect to x, or dy/dx, for the given equation is y' = (y - 12x) / (1 - x).
We start by differentiating both sides of the equation with respect to x.
For the left-hand side, the derivative of y + 3 with respect to x is simply dy/dx, or y'.
For the right-hand side, we need to apply the product and chain rules.
Differentiating xy with respect to x gives us x(dy/dx) + y.
Differentiating -6x² with respect to x gives us -12x.
Putting it all together, we have y' + 0 = x(dy/dx) + y - 12x.
Rearranging the equation, we get y' = (y - 12x) / (1 - x).
Therefore, the derivative of y with respect to x, or dy/dx, for the given equation is y' = (y - 12x) / (1 - x).
