(a) An equation for the (non-zero) vertical (x -)nullcline of this system is and for the (non-zero) horizontal (y-)nullcline is y = 1 - x/3 and x = 1 - y/4
(b) The equilibrium points for the system are (0,0) and (1,1).
c) If we start at the initial position (2,2), trajectories approach the point (1,1).
The system of equations we will consider is:
dx/dt = x(1 - x/3 - y)
dy/dt = y(1 - y/4 - x)
To find the vertical (x-)nullcline, we set dx/dt to 0 and solve for y. This gives us:
1 - x/3 - y = 0
y = 1 - x/3
Similarly, to find the horizontal (y-)nullcline, we set dy/dt to 0 and solve for x. This gives us:
1 - y/4 - x = 0
x = 1 - y/4
The nullclines represent the points in the phase plane where either dx/dt or dy/dt is zero.
Therefore, any trajectory that passes through a nullcline will be tangent to that nullcline.
To find the (non-zero) vertical (x-)nullcline, we set x = 0 and solve for y. This gives us y = 1/x.
Therefore, the equation of the vertical nullcline is y = 1/x.
Similarly, to find the (non-zero) horizontal (-)nullcline, we set y = 0 and solve for x. This gives us x = y.
Therefore, the equation of the horizontal nullcline is x = y.
Next, we want to find the equilibrium points of the system, which are the points in the phase plane where both x and y are zero.
To find the equilibrium points, we set x = 0 and y = 0 and solve for x and y. This gives us two equilibrium points: (0,0) and (1,1).
To confirm that these are indeed equilibrium points, we can substitute them into the original equations and verify that x and y are both zero at these points.
Finally, we want to estimate trajectories in the phase plane using a phase plane plotter.
Suppose we start at the initial position (2,2). We can use the phase plane plotter to draw the trajectory that passes through this point. We observe that the trajectory approaches the equilibrium point (1,1) as t goes to infinity.
Therefore, we can complete the sentence as follows: If we start at the initial position (2,2), trajectories approach the point (1,1).

Jimmy invests $2500 in an account with a 5% interest rate, making no other deposits or withdrawals. What will Jimmy’s account balance be after 8 years if the interest is compounded 6 times each year?
URGENT PLEASE
Answer:
We conclude that the total amount accrued, principal plus interest, from compound interest on an original principal of $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.
Step-by-step explanation:
Given
Principle P = $2500
Interest rate r = 5% = 0.05
Time period t = 8 years
To determine
Accrue Amount A = ?
Using the compound interest equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
where:
A represents the Accrue Amount
P represents the Principal Amount
r represents the interest rate
t represents the time period in years
n represents the number of compounding periods per unit t
Important tip:
Given that the interest is compounded 6 times each year, therefore, the value of n = 6.now substituting P = 2500, r = 0.05, t = 8 and n = 6 in the equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
[tex]A=2500\left(1+\frac{0.05}{6}\right)^{\left(6\right)\left(8\right)}[/tex]
[tex]\:A=2500\left(1+\frac{0.05}{6}\right)^{48}[/tex]
[tex]A=2500\times 1.48935[/tex] ∵ [tex]\left(1+\frac{0.05}{6}\right)^{48\:\:}=1.48935[/tex]
[tex]A=\:3723.38[/tex] $
Therefore, we conclude that the total amount accrued, principal plus interest, from compound interest on an original principal of $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.

7. Find the m 2 JKL
in rhombus JKLM
Step-by-step explanation:
since KLJ is a parallelogram, it can be split into 2 congruent triangles, as seen above. The angles remain the same, so we know angle KJL is also 25 degrees. Using the triangle angle sum theorem (all sides of a triangle add up to 180 degrees), we can determine the missing angle measure is 25 degrees. It would have been nice if the question told us JKLM was also a rhombus.

PLS HELP ASAP
{y,x} = {10,-5}
Step-by-step explanation:
sorry if this dont make sense
solve equation [2] for the variable y
y = 4x +30
plug this in for variable y in equation [1 ]
(4x+30) +3x= -5
solve [1] for the variable x
7x= - 35
x= - 5
by now we know this much
y= 4x+30
x= - 5
use the x value to solve for y
y=4 (-5) + 30 = 10
solution
{y,x} = {10,-5}
What does y = 1/3x + 5 look like on a graph?

Answer:
$44.80
Step-by-step explanation:
Here' s an equation to help you with percent problems: part %
------- = -----
whole 100
Because you want to find 12%, the % in the equation would be replaced with 12. The part would be x because that's what u need to find. The whole would be 40. Cross multiply to get 100x = 480. Divide 480 by 100 to get x = 4.80. Add 4.80 to 40.00 to get the final price. The final price is $44.80.

find an equation of line containing (3, -4) and having slope -2. if this line contains the points (a, 8) and (5, b) find a and b
Answer:
a = -3
b = -8
Step-by-step explanation:
Equation for a line is:
y-coordinate = (slope * x-coordinate) + y-intercept
For (3, -4): -4 = (-2 * 3) + y-intercept
y-intercept = 2
Equation for all points on this line is:
y = -2*x + 2
For (a, 8): 8 = (-2 * a) + 2
For (5, b): b = (-2 * 5) + 2

Jasmine had some candy to give to her three children. She first took four pieces for herself and then evenly divided the rest among her children. Each child received two pieces. With how many pieces did she start?
Answer:
10 pieces
Step-by-step explanation:
She gave herself 4 pieces, and each child 2 pieces. If she has 3 children, she gave them 6 pieces.
(3*2=6) and then you add with the amount she gave herself, (6+4) that would be 10. She started with 10 pieces.
An equation would be:
x= 4+(2*3)
