Hi, the rest of the question is:

How do you write a system of linear inequalities to model the situation?

So, for the first inequality:

The sum of the number of soil bags (x) and plants(y) bought must be less or equal to 20.

x+y ≤20

For the second inequality:

The product of the number of soil bags (x) and the price of each bag (3.50) ; plus the number of plants bought(y) and the price of each plant (8) must be less or equal to 150.

3.50 x +8 y ≤150

In conclusion, the system is:

x+y ≤20

3.50 x +8 y ≤150

Answer:

1/7

Step-by-step explanation:

6 + 5 + 4 = 15

There are 15 marbles to start with.

p(event) = (number of desired outcomes)/(total number of outcomes)

First pick (there are 6 desired outcomes out of a total of 15 possible outcomes):

p(r) = 6/15

Now there are 5 red marbles left and a total of 14 marbles left.

Second pick (there are 5 desired outcomes out of a total of 14 possible outcomes):

p(r) = 5/14

These events are independent, so we multiply the two probabilities.

p(r, r) = 6/15 × 5/14

p(r, r) = 3/7 × 1/3

p(r, r) = 1/7

The transformation f(x) ↦ f(x) -1/2 shifts the graph of f(x) downward by 2 units.

For example, suppose that point (a, b) lies on the graph of f(x). After applying the transformation f(x) ↦ f(x) - 1/2, the point (a, b - 1/2) lies on the transformed graph.

So, when the original graph of f(x) was above the x-axis, the transformed graph will be shifted downward and intersect the x-axis 1/2 units below where the original graph intersected it.

When the original graph of f(x) was below the x-axis, the transformed graph will be shifted downward and move further away from the x-axis.

The particular solution that satisfies the given initial conditions is y(x) = y(x) = y(x) = e^2x + 6e^(-3x).

To verify that y1 = e^2x and y2 = e^(-3x) are solutions to the differential equation y'' + y' - 6y = 0, we substitute them into the equation:

For y1:

y'' + y' - 6y = (e^2x)'' + (e^2x)' - 6(e^2x) = 4e^2x + 2e^2x - 6e^2x = 0

For y2:

y'' + y' - 6y = (e^(-3x))'' + (e^(-3x))' - 6(e^(-3x)) = 9e^(-3x) - 3e^(-3x) - 6e^(-3x) = 0

Both y1 and y2 satisfy the differential equation.

To find a particular solution that satisfies the initial conditions y(0) = 7 and y'(0) = -1, we express y(x) as y(x) = c1y1 + c2y2, where c1 and c2 are constants. Substituting the initial conditions into this expression, we have:

y(0) = c1e^2(0) + c2e^(-3(0)) = c1 + c2 = 7

y'(0) = c1(2e^2(0)) - 3c2(e^(-3(0))) = 2c1 - 3c2 = -1

Solving this system of equations, we find c1 = 1 and c2 = 6. Therefore, the particular solution that satisfies the given initial conditions is y(x) = y(x) = y(x) = e^2x + 6e^(-3x).

Step-by-step explanation:

Since there are 5 premium channels, we multiply the rate of charges by the number of premium channels to get the extra payment.

5 channels x 12$ per channel = 50$  

Now we add this to 35 since C= 35 + 12 or 35 plus the premium channel costs

Mrs. Green can serve a total of six different combinations of two vegetables from the given options.

To find out, we can use the combination formula: \(nCr = n! / (r! * (n-r)!)\)

where n is the total number of items to choose from, and r is the number of items to choose. In this case, n = 4 (carrots, peas, okra, and green beans) and r = 2 (the number of vegetables to be served).

Therefore, the formula becomes: 4C2 = 4! / (2! * (4-2)!)

= (4 * 3 * 2 * 1) / [(2 * 1) * (2 * 1)]

(3)

the values of q decrease as the values of p increase.

this indicates an inverse relationship between the quantities, that is

q = \(\frac{k}{p}\) ← k is the constant of variation

to find k use any ordered pair from the table.

using q = 16 when p = 3 , then

16 = \(\frac{k}{3}\) ( multiply both sides by 3 )

48 = k

q = \(\frac{48}{p}\) ← equation of variation

(4)

the values of q increase as the values of p increase.

this indicates the quantities are in direct variation, that is

q = kp ← k is the constant of variation.

to find k use any ordered pair from the table.

using q = 2 when p = 6 , then

2 = 6k ( divide both sides by 6 )

\(\frac{2}{6}\) = k , that is

k = \(\frac{1}{3}\)

q = \(\frac{1}{3}\) p ← equation of variation

The first term of the infinite geometric series is 625.Let's dive deeper into the explanation.

We are given that the sum of the infinite geometric series is \(\( \frac{15625}{24} \)\)and the common ratio is\(\( \frac{1}{25} \).\)The formula for the sum of an infinite geometric series is \(\( S = \frac{a}{1 - r} \)\), where \( a \) is the first term and \( r \) is the common ratio.
Substituting the given values into the formula, we have \(\( \frac{15625}{24} = \frac{a}{1 - \frac{1}{25}} \).\)To find the value of \( a \), we need to isolate it on one side of the equation.
To do this, we can simplify the denominator on the right-hand side.\(\( 1 - \frac{1}{25} = \frac{25}{25} - \frac{1}{25} = \frac{24}{25} \).\)
Now, we have \(\( \frac{15625}{24} = \frac{a}{\frac{24}{25}} \).\) To divide by a fraction, we multiply by its reciprocal. So, we can rewrite the equation as \( \frac{15625}{24} \times\(\frac{25}{24} = a \).\)
Simplifying the right-hand side of the equation, we get \(\( \frac{625}{1} = a \).\)Therefore, the first term of the infinite geometric series is 625.
In conclusion, the first term of the given infinite geometric series is 625, which corresponds to option (a).

To calculate the receivable days, divide the trade receivables (RM63,000) by the average daily sales (RM1,400) to get approximately 45 days.



To calculate the receivable days, we need to determine the average daily sales and then divide the trade receivables by that figure.

First, we calculate the average daily sales by dividing the total sales by the number of days in the year:

Average daily sales = Total sales / Number of days

Since the year ended on 30th June 2019, there are 365 days in total.

Average daily sales = RM511,000 / 365 = RM1,400

Next, we divide the trade receivables by the average daily sales to find the receivable days:

Receivable days = Trade receivables / Average daily sales

Receivable days = RM63,000 / RM1,400 ≈ 45 days

Therefore, Alice's receivable days on 30th June 2019 is approximately 45 days.

The equation of a line passing through the point (5,-3) and parallel to 6x+3y=-12 is y =-2x+7.

Parallel lines are those that never intersect. As a result, two parallel lines must have the same slope but different intercepts (if they had the same intercepts, they would be identical lines).

The equation of the line is 6x+3y=-12.

6x+3y=-12​

3y =-12-6x

y = -2x-4    

The slope of this line is -2.

Because parallel lines have the same slope, the new line will also have a slope of -2.

You now have a point (5,-3) and a slope; thus, use the Point-Slope form to solve the equation of a line.

y-y₁= m(x-x₁)

y+3 = -2(x -5)

y+3 = -2x+10

Given that,

y = 16

Now put 16 instead of y to the equation.

\(16=\frac{25x}{6}-34\)

Now solve for x.

To find the equation of the tangent line to the polar curve r = 12cos(θ) at θ = π/2, we need to determine the slope of the tangent line and the point of tangency.

The equation of the line tangent to the polar curve r = 12cos(θ) at θ = π/2 is x = 0.

The slope of the tangent line. The slope of a polar curve at a given point can be found using the derivative formula:

dy/dx = (dy/dθ) / (dx/dθ)

In polar coordinates, the relationship between x and y is given by:

x = rcos(θ)

y = rsin(θ)

Differentiating both x and y with respect to θ,

dx/dθ = dr/dθcos(θ) - rsin(θ)

dy/dθ = dr/dθsin(θ) + rcos(θ)

Substituting r = 12cos(θ), we have:

dx/dθ = d(12cos(θ))/dθ×cos(θ) - 12cos(θ)sin(θ)

dy/dθ = d(12cos(θ))/dθsin(θ) + 12cos(θ)×cos(θ)

Simplifying these derivatives, we find:

dx/dθ = -12cos(θ)×sin(θ) - 12cos(θ)×sin(θ) = -24cos(θ)×sin(θ)

dy/dθ = 12cos(θ)×sin(θ) - 12sin²2(θ) + 12cos²2(θ) = 12cos(θ)

Now, let's substitute θ = π/2 into the derivatives:

dx/dθ = -24cos(π/2)sin(π/2) = -240×1 = 0

dy/dθ = 12cos(π/2) = 0

At θ = π/2, the derivatives dx/dθ and dy/dθ both evaluate to 0. This indicates that the curve is not changing with respect to θ at this point, implying that the tangent line is vertical.

The polar equation r = 12cos(θ) represents a circle with a radius of 12 centred at the origin. At θ = π/2, the point of tangency is on the circle with coordinates (0, 12).

Since the tangent line is vertical and passes through the point (0, 12), its equation can be written as x = 0.

Answer: 1.57 x 104

Step-by-step explanation: How to Convert a Number to Scientific Notation

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

The correct statement is that F(x) < 0 over the intervals (-0.7, 0.76) and (2.5, ∞).

The minimum value of (1.9, negative 5.7) is to the left of the x-axis, indicating that the function is negative over the interval (-0.7, 0.76). The maximum value of (0, 2) is above the x-axis, indicating that the function is negative over the interval (2.5, ∞).
