Answer:
[tex]\frac{dy}{dx}[/tex] = ([tex]\frac{dy}{dt}[/tex]) / ([tex]\frac{dx}{dt}[/tex]) = (36[tex]e^{4}[/tex]) / (-5) = -7.2[tex]e^{4}[/tex]
Step-by-step explanation:
To find the slope of the tangent line, we need to find [tex]\frac{dx}{dt}[/tex] and [tex]\frac{dy}{dt}[/tex], and then evaluate them at t=1 and compute [tex]\frac{dy}{dx}[/tex].
We have:
x(t) = 2[tex]t^{3}[/tex] - 8[tex]t^{2}[/tex] + 5t + 3
Taking the derivative with respect to t, we get:
[tex]\frac{dx}{dt}[/tex] = 6[tex]t^{2}[/tex] - 16t + 5
Similarly,
y(t) = 9[tex]e^{4t-4}[/tex]
Taking the derivative with respect to t, we get:
[tex]\frac{dy}{dt}[/tex] = 36[tex]e^{4t-4}[/tex]
Now, we evaluate [tex]\frac{dx}{dt}[/tex] and [tex]\frac{dy}{dt}[/tex] at t=1:
[tex]\frac{dx}{dt}[/tex]= [tex]6(1)^{2}[/tex] - 16(1) + 5 = -5
[tex]\frac{dy}{dt}[/tex] = 36[tex]e^{4}[/tex](4(1)) = 36[tex]e^{4}[/tex]
So the slope of the tangent line at t=1 is:
[tex]\frac{dy}{dx}[/tex]= ([tex]\frac{dy}{dt}[/tex]) / ([tex]\frac{dx}{dt}[/tex]) = (36[tex]e^{4}[/tex] / (-5) = -7.2[tex]e^{4}[/tex]

How do you write coordinates in quadratic form?
To write coordinates in quadratic forms,
Obtain the equation y = ax2 + bx + c.Determine -b / 2A. The vertex's x-coordinate is given here.Simply enter the value of -b / 2a into the equation for x and solve for y to obtain the vertex's y-coordinate. The vertex's y-coordinate is given here.What is coordinate quadratic function?When a quadratic equation is written in standard form, the vertex's coordinates are (-b/2a, f(-b/2a)), where x = -b/2a and y = f(-b/2a). This suggests that the formula x = -b/2a should be used to determine the x-value of the vertex in the equation y = -3x2 + x + 1. The equation for a straight line, y = mx + c, is one of the key coordinate geometry formulas. The angle that the line makes with the positive x-axis is represented by the symbol, where m is the slope and c is the y-intercept (tan = m).When you write coordinates as (x, y), it means to write the x-axis point first and then the y-axis point.To learn more about quadratic form refer to:

Answer:
1. (0,2)
2. (-2,-1)
Step-by-step explanation:
1.
y = 2x + 2
y = x + 2
2x + 2 = x + 2
2x = x
x = 0
Now we put 0 back in for x and solve for y
y = 2(0) + 2
y = 2
So, our answer for Q1 is (0,2)
2.
y = 3x + 5
y = -x - 3
3x + 5 = -x - 3
4x + 5 = -3
4x = -8
x = -2
Now we put -2 back in for x and solve for y
y = 3(-2) + 5
y = -6 + 5
y = -1
So, our answer for Q2 is (-2,-1)
Draw all non-isomorphic simple graphs with three vertices. Do not label the vertices of the graph. You should not include two graphs that are isomorphic. Remember that it is possible for a graph to appear to be disconnected into more than one piece or even have no edges at all.
Three non-isomorphic simple graphs with three vertices are given in the figure below.
The first is a complete graph, in which all three vertices are connected to each other. It is represented by a triangle shape.
The second graph is a graph with one vertex connected to the other two, it is represented by a line with two branches.
The third graph is a graph with no edges, it is represented by three isolated points.
Remember that two graphs are isomorphic if one can be transformed into the other by relabeling the vertices. It's important to note that these are the only three possible non-isomorphic simple graphs with three vertices.

The inverse of the equation y = - 4x + 3 is y = (3 - x)/4.
What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
Given, An equation y = - 4x + 3.
To find the inverse we'll first solve for 'x'.
Therefore,
y = - 4x + 3.
4x = 3 - y.
x = (3 - y)/4.
Now, we'll interchange the positions of 'x' and 'y'.

suppose you spend $180 on equipment to make a new board game. In addition, each game costs $2 to make. After doing market research, you determine that the games will sell or $20 each.
what is the y-intercept of the cost equation?
Answer:
The y-intercept of an equation is the point where the line crosses the y-axis, i.e when x = 0.
In this case, the cost equation is C = 2x + 180, where C is the total cost and x is the number of board games produced.
So when x = 0, C = 2(0) + 180 = 180
Therefore, the y-intercept of the cost equation is (0,180)
So the y-intercept of the cost equation is 180.

Isa earns a salary of $32,500 per annum. If he works an average of 34 hours a week calculate his hourly rate of pay
His hourly pay rate is $18.38 if he works 34 hours a week an earns $32,500 per annum.
What does per annum mean?Per annum denotes yearly or annually. It is a phrasing used frequently to describe interest rates. In sentences like "I have a 4% mortgage loan" or "This bond pays interest at a rate of 6%," "per annum" is frequently left out.
An illustration is when a supplier offers a credit customer a 2% early-payment discount for paying an invoice in 10 days as opposed to the full amount in 30. In this instance, the supplier forfeits 2% of the invoice amount in exchange for receiving payment 20 days early.
We recalculate the amounts and multiply both the "2%" and the "20 days" by 18 to get the rate per year. The annual rate that results is roughly 36%.
Isa works 34 hours a week
There are total 52 weeks a years
In a year the time he works is = 52 × 34 h
= 1768 hours
His annual salary is $32,500
Then his hourly rate of income = 32500/1768
= 32500/1768
= $18.38
Thus, his hourly pay rate is $18.38 if he works 34 hours a week an earns $32,500 per annum.

How do you find the equation of a line with 2 points in Class 10?
Steps to find the equation of a line with 2 points mentioned below:
What is equation of line?In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, first determine the slope and y-intercept. The ratio of y to x is known as the slope. A slope triangle should be drawn connecting any two spots you find along the line.
To determine a line's equation from two points following steps are there:
1. Determine the slope and used the slope formula.
Slope(m) = (y₂ - y₁) / (x₂ - x₁)
2. To determine the y-intercept, use the slope and one of the points(b).
The x and y in your equation y = mx + b may be replaced by one of your locations, and the m can be replaced by the slope you just computed. The only variable remaining is b in such case. To solve for b, use the same methods you would to solve for a variable.
3. Once you have the values for m and b, you can use them to solve for the line's equation in the slope-intercept form (y = mx + b).

How do I find the solution to a system?
If the system consists of 2 variables we can use the method of elimination or substitution to get the answer easily.
In the method of elimination from the two given sets of equations, we make one of the coefficients of a variable the same so that when in the next step when we will subtract them they will get canceled out and we will get the value of one of the variables which after substituting in one of the equation we'll get the value of another variable.
If we have more than 2 variables the method of row reduction using a matrix is the best way to solve the system. In the system we make an augmented matrix of the coefficients of the variables and row reduce them in such a way that when we multiply the matrix with the row matrix we get the values of the variables easily.

How do you change to base 5?
Change to base 5 can be done by dividing the decimal number by 5 and then taking the remainder of the division in reverse order.
The number base is the number that forms the basis for the formation of other numbers in a number system.
The number base that we use a lot every day is the decimal system, which consists of 10 numbers, from 0 to 9. This decimal system is usually called the base 10 number system. Apart from base 10, there are also other base systems, for example, base 2 (biner system), 8 (octal system), and 16 (hexadecimal system) which are usually used in computer / digital systems.
Change of base 10 numbers to other base numbers is done by:
dividing the decimal number by the intended base number, writing the remainder down, repeating the division until the remainder is zero, taking a look at the remainder in reverse order.For example, we want to change 214₁₀ to a base 5 number:
214 : 5 = 42 remainder 4
42 : 5 = 8 remainder 2
8 : 5 = 1 remainder 3
1 : 5 = 0 remainder 1
