Function 1 have more negative slope.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Function 1 is defined by the equation y = -2t + 6
Function 2:
Slope = 4/ 4 = 1
Then, the equation would be
y - 0 = 1( t- 4)
y= t - 4
Hence, Function 1 have more negative slope.

Test the exactness of ODE, if not, use an integrating factor to make exact and then find general solution: (2xy-2y^2 e^3x)dx + (x^2 - 2 ye^2x)dy = 0.
It is requred to test the exactness of the given ODE and then find its general solution. Then, if the given ODE is not exact, an integrating factor must be used to make it exact.
This given ODE is:(2xy - 2y²e^(3x))dx + (x² - 2ye^(2x))dy = 0.To verify the exactness of the given ODE, we determine whether or not ∂Q/∂x = ∂P/∂y, where P and Q are the coefficients of dx and dy respectively, as follows: P = 2xy - 2y²e^(3x) and Q = x² - 2ye^(2x).Then, we have ∂P/∂y = 2x - 4ye^(3x) and ∂Q/∂x = 2x - 4ye^(2x).Thus, since ∂Q/∂x = ∂P/∂y, the given ODE is exact.To solve the given ODE, we have to find a function F(x,y) that satisfies the equation Mdx + Ndy = 0, where M and N are the coefficients of dx and dy respectively. This is accomplished by integrating both P and Q with respect to their respective variables. We have:∫Pdx = ∫(2xy - 2y²e^(3x))dx = x²y - y²e^(3x) + g(y), where g(y) is a function of y. We differentiate both sides of this equation with respect to y, set it equal to Q, and then solve for g(y). We have:(d/dy)(x²y - y²e^(3x) + g(y)) = x² - 2ye^(2x)Thus, g'(y) = 0 and g(y) = C, where C is a constant.Substituting the value of g(y) in the equation above, we get:x²y - y²e^(3x) + C = 0, as the general solution.The given ODE is exact, so we can solve it by finding a function that satisfies the equation Mdx + Ndy = 0. After integrating both P and Q with respect to their respective variables, we find that the general solution of the given ODE is x²y - y²e^(3x) + C = 0.

No free man shall be seized [arrested] or imprisoned, or stripped of his rights or possessions. Except by the lawful judgment of his peers. This quote from the Magna Carta shows the ideals that set up which branch of our government?
The Magna Carta quotation serves as a symbol of the principles upon which the Judicial department of government was founded. Option C is right as a result.
The idea that the king and his government were not above the law was originally codified in the Magna Carta, which was released in June 1215.
Magna Carta is a cornerstone of our individual liberty and it still serves as a protest against unconstitutional rule of law. Magna Carta, though not intended to be so at the time of its formation, has come to be seen by many as a pillar of democracy as well as liberty.

Compute E(X∣y),Var(X) and Var(Y). Suppose that f(x,y)={ 15x2y / 0 ; 0 otherwise
E(Y^2) = 15 ∫[0, ∞](1/3 * y^2 * ∞) dy
Since the integral diverges, E(Y^2) does not exist and therefore Var(Y) cannot be computed
To compute E(X|y), we need to find the conditional expectation of X given a specific value of y. In this case, we have the joint probability density function f(x, y) = 15x^2y.
To find E(X|y), we integrate the product of X and the conditional probability density function f(x|y) over the range of X:
E(X|y) = ∫(x * f(x|y)) dx
Since the conditional probability density function f(x|y) can be obtained by dividing f(x, y) by the marginal density function f(y), we have:
f(x|y) = f(x, y) / f(y)
In this case, the marginal density function f(y) can be obtained by integrating f(x, y) over the range of x:
f(y) = ∫(15x^2y) dx = 5y
Therefore, the conditional probability density function becomes:
f(x|y) = (15x^2y) / (5y) = 3x^2
Now we can compute E(X|y):
E(X|y) = ∫(x * f(x|y)) dx = ∫(x * 3x^2) dx = ∫(3x^3) dx = [3/4 * x^4] evaluated from 0 to ∞ = ∞
Since the integral diverges, the conditional expectation of X given y does not exist.
To compute Var(X), we use the formula:
Var(X) = E(X^2) - (E(X))^2
Since E(X) does not exist, Var(X) cannot be computed.
To compute Var(Y), we use the formula:
Var(Y) = E(Y^2) - (E(Y))^2
To find E(Y^2), we integrate the product of Y^2 and the joint probability density function f(x, y):
E(Y^2) = ∫∫(y^2 * f(x, y)) dxdy
E(Y^2) = ∫∫(15x^2y * y) dxdy = 15 ∫∫(x^2y^2) dxdy
Integrating over the appropriate ranges, we obtain:
E(Y^2) = 15 ∫[0, ∞] ∫0, ∞ dxdy
E(Y^2) = 15 ∫[0, ∞](y^2 ∫0, ∞ dx) dy
E(Y^2) = 15 ∫[0, ∞](y^2 * [1/3 * x^3] evaluated from 0 to ∞) dy
E(Y^2) = 15 ∫[0, ∞](1/3 * y^2 * ∞) dy
Since the integral diverges, E(Y^2) does not exist and therefore Var(Y) cannot be computed.

State what additional information is required in order to know that the triangles are congruent by the SSS Triangle Congruence Postulate
Answer:
E
Step-by-step explanation:
You already know that TS = AB and TU = BC because it shows that in the images using the tick marks. SSS Triangle Congruence Postulate is when two triangles are congruent to each other because all the corresponding side lengths are equal to each other. So we already have two side lengths that are equal to each other, and, in order for SSS to be true, we need all 3 side lengths to be equal to each other. The only two side lengths not equal to each other yet are US and CA so if those were to be equal to each other, all corresponding side lengths would be equal to each other.
Let me know if you have any questions.
What value of c makes the equation true? Assume x>0 and y>0 3√x^3/cy^4=x/4y(3√y) c = 12 c = 16 c = 81 c = 64
The value of c that makes the equation true is c = 64, when x = 6 and y = 3.
To find the value of c that makes the equation true, we can start by simplifying both sides of the equation using exponent rules and canceling out common factors.
First, we can simplify 3√(x^3) to x√x, and 3√y to y√y, giving us:
x√x/cy^4 = x/4y(y√y)
Next, we can simplify x/4y to 1/(4√y), giving us:
x√x/cy^4 = 1/(4√y)(y√y)
We can cancel out the common factor of √y on both sides:
x√x/cy^4 = 1/(4)
Multiplying both sides by 4cy^4 gives us:
4x√x = cy^4
Now we can solve for c by isolating it on one side of the equation:
c = 4x√x/y^4
We can substitute in the values of x and y given in the problem statement (x>0 and y>0) and simplify:
c = 4x√x/y^4 = 4(x^(3/2))/y^4
c = 4(27)/81 = 4/3 = 1.33 for x = 3 and y = 3
c = 4(64)/81 = 256/81 = 3.16 for x = 4 and y = 3
c = 4(125)/81 = 500/81 = 6.17 for x = 5 and y = 3
c = 4(216)/81 = 64 for x = 6 and y = 3

Step-by-step explanation:
An equation is linear if equal changes in x produce equal changes in y.
Let's look at each choice.
1)
A decrease of 10% per year. That means each year, the value of the car is 0.9 times the value of the previous year.
For example, if the original value was $10,000, after 1 year, it is worth 0.9 * $10,000 = $9,000. In 1 year it lost $1,000. In the next year, its value is now 0.9 * $9,000. The value at the end of the 2nd year is $8,100. In the second year, it lost $900 in value. In one period of 1 year it lost $1000 in value. In another equal period of 1 year, it lost $900 in value. A change of 1 year in time produces different changes in loss of value, so it is not linear.
2)
Here, the number doubles every year. Let's say it starts with 100 fish. After 5 years, it has 200 fish. In a change of 5 years in x, the change in y is 100. In the next 5 years, it goes from 200 fish to 400 fish. The change in the second period of 5 years is 200. We see that a change of 5 years can produce a change of 100 fish, but another change of 5 years can produce a change is 100 fish. Since for equal changes in x, the changes in y are not all equal, this is not linear.
3)
Here for every change of 1 day in x, the change in y is 2 liters. Each change of 1 in x always produces a change of 2 in y. This is linear.
4)
Each 2 hours, the amount of caffeine is 2/3 of what it was before. This is similar to the choice 1), and it is not linear.

A restaurant offers a catering service which costs $16.50 per person with a $74.75 service charge. For parties of 40 or more people, a group discount applies, and the cost is $11.75 per person along with the service charge dropping to $37.00. Write a piecewise-defined function which calculates the total cost, T, (in dollars) of the catering service, which serves n people.
Answer:
16.50+91.25=91.25
91.25×40=3650
11.75-37.00=-25.25
Total cost, T of the catering service, which serves n people = T = 16.50n + 74.75 and T = 11.75n + 37.00
Given,
Charges per person = 16.50
Service charges = 74.75
Let n be the number of the people,
Let T be the total cost
Now, according to the given question,
T = 16.50n + 74.75
If n>=40
T = 11.75n + 37.00
So, we have 2 equations which define the total cost -
T = 16.50n + 74.75,
T = 11.75n + 37.00

c. 1.6
d. 0.63
The total inductance of two inductors connected in parallel with inductance values of 2 H and 8 H (with no mutual inductance) is 1.6 H.
When two inductors are connected in parallel, the total inductance can be calculated using the formula for the equivalent inductance of a parallel combination, which states that the reciprocal of the total inductance is equal to the sum of the reciprocals of the individual inductances. In this case, we have two inductors with inductance values of 2 H and 8 H.
Using the formula, we can calculate the total inductance as follows:
1/L_total = 1/L1 + 1/L2
1/L_total = 1/2 + 1/8
1/L_total = 4/8 + 1/8
1/L_total = 5/8

Answer:

An equation is formed when two equal expressions. The equation of the line passing through the intersection and the point (-5,2) is y=(-0.3781)x+ 0.1092.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
Given the two equations x + 3y=0 and 4x − 4y −13=0. The intersection of the equation can be found as,
Solve the first equation for x,
x+ 3y = 0
x = -3y
Solve the second equation, by substituting,
4x − 4y −13=0
4(-3y) − 4y −13=0
-12y - 4y -13 = 0
-16y = 13
y = 13/(-16)
y = -0.8125
Substitute the value of x,
x = -3y
x = -3(-13/16)
x = 39/16
x = 2.4375
Hence, the coordinate of the point of intersection is (2.4375, -0.8125).
Now, the slope of the line passing through the intersection and the point (-5,2) is,
Slope, m = (2 + 0.8125)/(-5-2.4375)
= -2.8125/7.4375
= -0.3781
Substitute the slope and the coordinate in the equation of the line,
y = mx + c
2 = (-0.3781)(-5) + c
2 - 1.89 = c
c = 0.1092
Hence, the equation of the line passing through the intersection and the point (-5,2) is y=(-0.3781)x+ 0.1092.

what is the radius of a right circular cylinder with a volume of 12 in3 if it has a minimum surface area?
The value of radius of a right circular cylinder is 1,248 in for which the minimum surface area is obtained.
Define right circular cylinder?A cylinder with two circular bases and a line connecting their centers that is perpendicular to both bases.Volume of the right circular cylinder be;
v(c) = 12 in³ = π*r²*h
In which, h is the height of the cylinder,
Then , h = 12 / π*r²
Surface area of a right circular cylinder is:
S = area of base and top + lateral area
S(A) = 2*π*r² + 2*π*r*h ....eq 1
Put value of 'h' in equation (1)
S(r) = 2*π*r² + 2*π*r* ( 12 / π*r²)
S(r) = 2*π*r² + 24 /r
Differentiate both sides,
S´(r) = 4*π*r - 24 /r²
Put , S´(r) = 0 to get the critical points.
4*π*r - 24 /r² = 0
π*r - 6/r² = 0
π*r³ - 6 = 0
r³ = 1,91
r = 1,248 in
Check for the minimum surface area for r = 1,248 in.
Find the second derivative,
S´´(r) = 4*π + 48/r³
S´´(r) will always be positive.
Thus, the minimum surface area S is for r = 1,248 in.

Step-by-step explanation:
32,000*6*.07=13440
13440+32,000+45,440
The amount we have to pay at the end of the 6month period will be $33,120. The rate of interest on the loan is given as per annum and therefore; the interest is to be calculated for 6 months.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
Calculation of settlement amount of loan:
Given:
Principle= $32,000
Rate= 7%
Tenure= 6 months
Interest is calculated from the following formula;
Interest= Principle x rate x tenure
Therefore the interest for the loan will be;
Interest = $32,000 x 7 x 6 months
= 32,000 x 7/100 x 6/12
= $1,120
The final payment for the loan will be the combination of principal and interest.
Therefore final payment = $32,000 +$1,120
= $33,120
