So, we just set the side values equal to each other.

This gives us:

6x-5 = 4x+13

-4x      -4x

2x-5 = 13

   +5   +5

2x = 18

Then, divide both sides by 2

Let's denote Ken's salary as "S". The amount left after buying the oven is S - $740. Then, 1/4 of this amount is equal to 1/5 of his salary:

From the given information, we know that Ken spent $740 on an oven and 3/4 of the remaining money on a laptop. This means he has 1/4 of the remaining money left.

(1/4)(S - $740) = 1/5S

To solve for S, we can multiply both sides of the equation by 20:

5(S - $740) = 4S

Solving this equation will give us the value of Ken's salary.

To find the inverse of a matrix using the reduced-row-echelon method, we augment the given matrix with the identity matrix of the same size and perform row operations to transform the given matrix into the reduced-row-echelon form. The resulting augmented matrix will have the inverse of the original matrix on the right-hand side.

Using the reduced-row-echelon method, we can perform row operations to convert the given matrix (

To solve the problem, we need to find out how much longer it would take for Samir's money to double compared to Penelope's money, given that Penelope invested $89,000 in an account with a continuous interest rate of 6%, while Samir invested $89,000 in an account with a monthly compounded interest rate of 6⅜%.

For Penelope's investment, we can use the formula for continuous compounding, which is A = Pe^(rt), where A is the amount of money after t years, P is the initial investment, r is the interest rate as a decimal, and e is the natural logarithm base. We know that Penelope invested $89,000 and we want to find t such that A = 2P = $178,000. Thus, we have:

$178,000 = $89,000e^(0.06t)

Dividing both sides by $89,000 and taking the natural logarithm of both sides, we get:

ln(2) = 0.06t

Solving for t, we get:

t = ln(2)/0.06 ≈ 11.55 years

For Samir's investment, we can use the formula for monthly compounded interest, which is A = P(1 + r/12)^(12t), where A, P, r are the same as before, and t is the time in years divided by 12. Similarly, we know that Samir invested $89,000 and we want to find t such that A = 2P = $178,000. Thus, we have:

$178,000 = $89,000(1 + 0.0638/12)^(12t)

Dividing both sides by $89,000 and taking the logarithm (base 1 + r/12) of both sides, we get:

log(2)/log(1 + 0.0638/12) = 12t

Solving for t, we get:

t ≈ 11.80/12 = 0.98 years

To find the difference in time it takes for Samir's money to double compared to Penelope's, we subtract the time it takes for Penelope's money to double from the time it takes for Samir's money to double:

0.98 - 11.55 ≈ -10.57

However, this answer doesn't make sense in the context of the problem, since it's negative. After reviewing our solution, we realized that we made a mistake in the calculation of t for Penelope's investment. We need to find the time it takes for Penelope's investment to double with annual compounding, not continuous compounding. The formula for this is t = (ln(2))/(ln(1 + r)), where r is the annual interest rate as a decimal.

Plugging in the numbers, we get:

t = (ln(2))/(ln(1 + 0.06)) ≈ 11.55 years

This is the same as the time we got for Samir's investment, so the difference in time it takes for their money to double is:

0.98 - 11.55 ≈ -10.57

Again, this answer doesn't make sense in the context of the problem, since it's negative. Therefore, we need to revise our solution and approach the problem differently.

The formula relating the monetary multiplier and the reserve ratio shows that as the monetary multiplier increases, the reserve ratio decreases. If the monetary multiplier is 6, the reserve ratio must be 0.167.

To determine the reserve ratio given the monetary multiplier, we can use the formula:

Monetary Multiplier = 1 / Reserve Ratio

Given that the monetary multiplier is 6, we can substitute this value into the formula:

6 = 1 / Reserve Ratio

To isolate the reserve ratio, we can take the reciprocal of both sides of the equation:

1 / 6 = 1 / (1 / Reserve Ratio)

1 / 6 = Reserve Ratio

Therefore, the reserve ratio must be 1/6 or approximately 0.167.

Thus, parametric equation for the circumference of the ellipse : C ≈ 15.3.

To estimate the circumference of the ellipse given by the equation 16x^2 + 4y^2 = 64, we first need to find the parametric equations. Let's divide both sides of the equation by 64 to get:
x^2 / 4^2 + y^2 / 2^2 = 1

Now, we can use the parametric equations for an ellipse:
x = 4 * cos(t)
y = 2 * sin(t)

Now, we can find the arc length function ds/dt. To do this, we'll differentiate both equations with respect to t and then use the Pythagorean theorem:

dx/dt = -4 * sin(t)
dy/dt = 2 * cos(t)

(ds/dt)^2 = (dx/dt)^2 + (dy/dt)^2 = (-4 * sin(t))^2 + (2 * cos(t))^2

Now, find ds/dt:
ds/dt = √(16 * sin^2(t) + 4 * cos^2(t))

Now we can use Simpson's rule with n = 8 to estimate the circumference:
C ≈ (1/4)[(ds/dt)|t = 0 + 4(ds/dt)|t=(1/8)π + 2(ds/dt)|t=(1/4)π + 4(ds/dt)|t=(3/8)π + (ds/dt)|t=π/2] * (2π/8)

After plugging in the values for ds/dt and evaluating the expression, we find:
C ≈ 15.3 (rounded to one decimal place)

Answer:

9 and -4

Step-by-step explanation:

sketch of the line 4x + 3y = 11, slope (-4/3),  y-intercept of the line y = 11/3

Step 1: Convert the equation to slope-intercept form (y = mx + b) by solving for y:

3y = -4x + 11

y = (-4/3)x + 11/3

Step 2: Identify the slope and y-intercept:

From the equation in slope-intercept form, we can see that the slope (m) is -4/3 and the y-intercept (b) is 11/3.

Step 3: Plot the y-intercept:

On the y-axis, mark a point at y = 11/3 (approximately 3.67). This is the y-intercept of the line.

Step 4: Use the slope to find additional points:

Using the slope of -4/3, we can find other points on the line. The slope represents the change in y for every 1 unit change in x. So, starting from the y-intercept, we can move down 4 units and to the right 3 units to find the next point, and continue this pattern to find more points.

Step 5: Connect the points:

Once you have a few points on the line, you can connect them with a straight line. Make sure the line extends beyond the plotted points to show that it continues indefinitely.

The resulting line should have a negative slope (-4/3) and be slanting downward from left to right.

To calculate the moment of inertia about the x-axis, the moment of inertia about the y-axis, and the polar moment of inertia passing through point O, we need to determine the geometric properties of the given figure, such as the shape and dimensions.

To calculate the moment of inertia about the x-axis, we need to determine the area of the figure and the distance of each element from the x-axis. The moment of inertia about the x-axis, denoted as Ix, is given by the sum of the individual moments of inertia of each element about the x-axis.

Similarly, to calculate the moment of inertia about the y-axis (Iy), we need to determine the area of the figure and the distance of each element from the y-axis. The moment of inertia about the y-axis is given by the sum of the individual moments of inertia of each element about the y-axis.

The polar moment of inertia passing through point O (J) represents the resistance of the entire figure to torsional or rotational deformation. It is the sum of the moments of inertia about the x-axis and y-axis, denoted as Ix and Iy, respectively.

The specific calculation method will depend on the shape and dimensions of the figure. For example, if the figure is a rectangle, the formulas for calculating the moments of inertia and the polar moment of inertia can be found in engineering mechanics or solid mechanics textbooks.
