I have a F in this class may someone help me..?

Step-by-step explanation:

Since 4104 students are employed sophomores, juniors, or seniors, the total number of unemployed students is 11,989 - 4104 = 7885.

And since 745 students are employed freshman, the number of unemployed freshman is 7885 - 745 = 7140.

So, the total number of freshman is 745 + 7140 = 7885.

The Venn diagram would look like this:

[ Freshmen ] [ Sophomores, Juniors, Seniors ]

[ 7885 ] __________ [ 4104 ]

| 745 |

__________

[ 7140 ]

So, there are 7885 freshman.

The single transformation that is equivalent to a reflection over the x-axis, followed by a rotation of 90 degrees, is a reflection over the y-axis.

Here, we have,

we know that,

When you reflect a figure over the x-axis, all the points are flipped vertically, so a point (x, y) would become (x, -y).

Then, when you rotate the reflected figure by 90 degrees counterclockwise, the x-coordinate and y-coordinate swap places, resulting in (-y, x).

If we perform a reflection over the y-axis on the original figure (x, -y), the y-coordinate is negated, resulting in (-x, -y).

Then, when we rotate this figure by 90 degrees counterclockwise, the x-coordinate and y-coordinate swap, giving us (-y, -x), which is equivalent to (-y, x).

Therefore, a reflection over the y-axis achieves the same result as a reflection over the x-axis followed by a rotation of 90 degrees.

(a) 1.088 ×\(10^2\)

(b) 2.132

(c) 1.3331 ×\(10^1\) and

(d) 1.05.

Let's calculate the answers to the given operations using the appropriate number of significant figures.

(a) 8.370×1.3×10

To perform this multiplication, we multiply the decimal numbers and add the exponents of 10:

8.370 × 1.3 × 10 = 10.881 × 10 = 1.0881 × \(10^2\)

Since the original numbers have four significant figures, we round the final answer to four significant figures:

1.088 × \(10^2\)

(b) 4.265/2.0

For division, we divide the decimal numbers:

4.265 ÷ 2.0 = 2.1325

Since both numbers have four significant figures, the answer should be rounded to four significant figures:

2.132

(c) (1.2588×\(10^3\))×(1.06×\(10^-^2\))

This differential equation is of the form:
(x^2 + y^2)dx + (x^2 - xy)dy = 0

We can solve it by first integrating the left-hand side with respect to x. To do this, we need to rearrange the equation and integrate both terms individually. We have:
int (x^2 + y^2)dx = x^3/3 + xy^2 + C_1
int (x^2 - xy)dy = x^2y - frac{1}{2}y^2 + C_2
Therefore, the general solution of the differential equation is:
x^3/3 + xy^2 + C_1 = x^2y - \frac{1}{2}y^2 + C_2
Now we need to verify that the given function C_1(x + y)^2 = xe^{y/x} is a solution of this differential equation. To do this, we first substitute the given function for C_1 in the general solution and rearrange the equation:
x^3/3 + xy^2 + (x + y)^2 = x^2y - \frac{1}{2}y^2 + xe^{y/x}
We can now differentiate both sides of the equation with respect to x and simplify to get:
2x + y^2 + 2xy = 2xy + xe^{y/x}
If we simplify further, we get:
y^2 = xe^{y/x}

Answer:

In a bubble sort, on each pass through the list that must be sorted, the largest value "bubbles" to the end of the list. Therefore, after each pass, the end of the list is guaranteed to be sorted. This means that we can stop making pair comparisons one comparison sooner, which is option B.

Step-by-step explanation:

Bubble sort works by repeatedly comparing and swapping adjacent elements in the list if they are in the wrong order. During each pass through the list, the largest unsorted element "bubbles up" to its correct position. As a result, after the first pass, the largest element is in its correct position, after the second pass, the two largest elements are in their correct positions, and so on.

Therefore, with each subsequent pass, you can stop making pair comparisons one comparison sooner because the elements at the end of the list are already sorted.

Let's evaluate :

the height of the candle after 27 hours of burning is 0.6 centimeters.

Let h be the height of the candle and t be the amount of time it has been burning. It is given that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.

After 11 hours of burning, a candle has a height of 22.4 centimeters.

After 28 hours of burning, its height is 12.2 centimeters.

Therefore, we can write two linear equations using the given information:

y1 = mx1 + b where y1 = 22.4, x1 = 11 and y2 = 12.2, x2 = 28

Solving for m and b, we get:

y1 = mx1 + b22.4 = m(11) + b... (1)

y2 = mx2 + b12.2 = m(28) + b... (2)

Solving equation (1) for b, we get:

b = 22.4 - m(11)... (3)

Substituting equation (3) into equation (2) and solving for m, we get:

m = (12.2 - 22.4) / (28 - 11) = -1.4

Using equation (1) and the value of m, we get:

22.4 = (-1.4)(11) + b

22.4 = -15.4 + b

b = 37.8

Therefore, the equation of the line is:

h = -1.4t + 37.8

We can use this equation to find the height of the candle after 27 hours:

h = -1.4(27) + 37.8h = 0.6 centimeters

Therefore, the height of the candle after 27 hours of burning is 0.6 centimeters.

Based on the proof, the set {c1v1, c2v2} is also an orthogonal set.

It should be noted that to show that {c1v1, c2v2} is an orthogonal set, we need to show that their dot product is zero, i.e.,

(c1v1)⋅(c2v2) = 0

Expanding the dot product using the distributive property, we get:

(c1v1)⋅(c2v2) = c1c2(v1⋅v2)

Since {v1, v2} is an orthogonal set, their dot product is zero, i.e.,

v1⋅v2 = 0

Substituting this in the above equation, we get:

(c1v1)⋅(c2v2) = c1c2(v1⋅v2) = c1c2(0) = 0

Therefore, the set {c1v1, c2v2} is also an orthogonal set.

The long run behavior of the function f(x)=5(2)x+1 is that it approaches 1 as x approaches negative infinity and it approaches infinity as x approaches positive infinity.

The long-term behavior of the function f(x)=5(2)x+1 can be discovered by examining how the function behaves as x gets closer to negative and positive infinity.

As x→−[infinity], f(x) = 5(2)^ -∞+1 = 5(0)+1 = 1

As x approaches negative infinity, the value of the function approaches 1.

As x→[infinity], f(x) = 5(2)^ ∞+1 = 5(∞)+1 = ∞

As x approaches positive infinity, the value of the function approaches infinity.

As a result, the function f(x)=5(2)x+1 behaves in the long run in such a way that it approaches 1 as x approaches negative infinity and infinity as x approaches positive infinity.

If a cylinder has a volume of 600 cubic inches, and we want to find the volume of a cone with the same diameter and height as the cylinder, we can use the formula for the volume of a cone.

The formula for the volume of a cone is given as:

\(V = (1/3) * \pi * r^2 * h,\)

where V is the volume, π is a mathematical constant approximately equal to 3.14159, r is the radius of the base of the cone, and h is the height of the cone.

In this case, since the cylinder and cone have the same diameter, the radius of the cone's base will be half of the radius of the cylinder's base. Let's assume the radius of the cylinder's base is r_cylinder.

So, the radius of the cone's base will be r_cone = r_cylinder / 2.

The height of the cone will be the same as the height of the cylinder, denoted as h_cylinder.

Now, let's substitute these values into the volume formula for the cone:

V_cone = (1/3) * π * (r_cone)^2 * h_cylinder

      = (1/3) * π * (r_cylinder/2)^2 * h_cylinder

      = (1/3) * π * (r_cylinder^2 / 4) * h_cylinder

      = (π/12) * r_cylinder^2 * h_cylinder.

Since we know the volume of the cylinder is 600 cubic inches, which is equal to the volume of the cone, we have:

600 = (π/12) * r_cylinder^2 * h_cylinder.

From this equation, we can't directly calculate the specific values of r_cylinder and h_cylinder. We would need additional information or constraints to solve for them.

However, using the given information, we can conclude that the volume of the cone with the same diameter and height as the cylinder will also be 600 cubic inches, assuming the cylinder and cone share the same dimensions.
