Julie wants to buy tulip bulbs to plant. Each bulb costs $0.50 plus a one-time $4.50 shipping cost. She has $22 to spend.
Write an equation to determine how many bulbs b Julie can buy have shipped.

The length is decreasing by 7 in/sec and the width is shrinking at 10 in/sec , so the total area will decreased by -98 in/sec

The area is the total measurement of all the space enclosed by a closed geometric figure.

Using the area of rectangle to find the formula for the area and the perimeter shows us..

A = L*W

P = 2L + 2W

dA/dt = L * dW/dt. + dL/dt * W

dP/dt = 2 * ( dL/dt + dW/dt )

We are given the following information...

L = 8 inches

W = 4 inches

dL/dt = -7 in/sec ( decreasing so the sign is negative )

dW/dt = -10 in/sec ( decreasing so the sign is negative )

dA/dt =  L * dW/dt. + dL/dt * W

       =  8 * -10 +  -7 * 4

      =  -98 in/sec

the answer is None. There is no line of symmetry as the figure cannot fold and be equal on both sides

For a shape to have a line of symmetry, there must be a line that divides the shape into 2 halves that are the exact identical.

This shape doesn't have any line of symmetry (all the lines shown would be a line of symmetry if there is a transformation done to one of the halves)

The rule of inference being used here is Modus Tollens. Modus Tollens is a valid deductive argument form that states if a conditional statement "If P, then Q" is true and the consequent Q is false, then the antecedent P must also be false.

In the given scenario, the conditional statement is "If the guard dog doesn't know a person, then it barks."

The observation that the dog didn't bark (Q is false) leads to the conclusion that the dog must have known the person (the antecedent P is false).

Answer:

the equilibrium expected growth rate is 6.65%

Step by step Explanation:

We were given stock sold per share of $32.50

Dividend per share =$1.25

Required Return rate = 10.5%

Then we can calculate Percentage of Dividend for share as;

dividend of br. 1.25 per share at the end of the year (D1=br.1.25)

= 1.25×100= 125

Let the dividend percentage = y

stock sold per share × y= 125

125= 32.50y

y = 125/32.50

y= 3.85

y= 3.85*100%

Then the Dividend percentage = 3.85%

Growth rate=(required rate of return -Dividend percentage)

= 10.5 - 3.85 = 6.65

Therefore, the equilibrium expected growth rate is 6.65%

In order to determine if the point (20,13) is on the line, it is necessary to write the equation of the line.

The general form of a linear equation is:

y = mx + b

where b is the y-intercept and m is the slope. Y-intercept is the value of y when x = 0. You can observe in the graph that b = 3.

The slope m is conputed by using the following formula:

where (x1,y1) and (x2,y2) are two points of the line. Use the points (0,3) and (6,6), you can select any other two points. Replace these values into the formula for m:

Then, the equation of the line is:

Now, replace the value of x = 20 in the previous equation, if y = 13, then the point (20,13) in on the line:

Trying to factor by splitting the middle term

4.2     Factoring  3k2 + 5k - 28

The first term is,  3k2  its coefficient is  3 .

The middle term is,  +5k  its coefficient is  5 .

The last term, "the constant", is  -28

Step-1 : Multiply the coefficient of the first term by the constant   3 • -28 = -84

Step-2 : Find two factors of  -84  whose sum equals the coefficient of the middle term, which is   5 .

     -84    +    1    =    -83

     -42    +    2    =    -40

     -28    +    3    =    -25

     -21    +    4    =    -17

     -14    +    6    =    -8

     -12    +    7    =    -5

The height is 2 and radius is √2 of the largest right circular cylinder that can be put into a sphere of radius √3.

A cylinder whose bases are circular in shape and parallel to each other is called the right circular cylinder. It is a three-dimensional shape.

Given that the radius of a sphere R = √3

Let the radius of the cylinder is r and the height of the cylinder is h.

than.

r² = R² − h²/4

and Vc = πr²h

⇒ Vc = π(R² − h²/4)h

⇒ Vc = πR²h − πh³/4

dVc/dh = πR² − 3πh²/4  

(dVc/dh)R=√3 = 3π − 3πh²/4

For maximum or minimum volume,

dVc/dh = 0

⇒ 3π − 3πh²/4 = 0

⇒ 3πh²/4 = 3π

⇒ 3πh² = 3π*4

⇒ h² = 4

⇒ h=2

Also,  dVc/dh changes sign from positive to negative in the neighborhood of h=2. Hence, h=2 is a maximum point.

r² = R² − h²/4

⇒ r² = (√3)² - 2²/4

⇒ r² = 3 - 1

⇒ r² = 2

​⇒ r = √2

So, the height is 2 and radius is √2 of the largest right circular cylinder

The probability that a person has a disease given that they test positive, when 0.4% of the population has the disease and the test is positive with probability 0.99 if they have the disease and 0.03 if they don't have it, is 0.116 or about 11.6%.

Let D be the event that the person has the disease and T be the event that the person tests positive. We need to calculate P(D|T), the probability that the person has the disease given that they test positive.

Using Bayes' theorem, we have

P(D|T) = P(T|D) * P(D) / P(T)

where P(T|D) is the probability of testing positive given that the person has the disease, P(D) is the prior probability of having the disease, and P(T) is the total probability of testing positive, which can be calculated as

P(T) = P(T|D) * P(D) + P(T|D') * P(D')

where P(T|D') is the probability of testing positive given that the person does not have the disease, and P(D') is the complement of P(D), which is the probability of not having the disease.

Substituting the given values, we get

P(D|T) = (0.99 * 0.004) / [(0.99 * 0.004) + (0.03 * 0.996)]

= 0.116

Therefore, the probability that the person has the disease given that they test positive is 0.116 or about 11.6%.

Answer:

A. The inequalities are:

\(w + 38 \leq 50\)

\(38 + w \leq 50\)

\(w \leq 50 - 38\)

B. No, the total being added is 14 pounds, which is not a solution to the inequality.

Step-by-step explanation:

Given

\(Maximum = 50\)

\(Bag = 38\)

Solving (a): Expression that represent the possible additional weight

Represent the additional weight with w

When w is added to the weight of the bag it must not be more than 50;

Not more than means less than or equal to

This is represented by

\(w + 38 \leq 50\) or \(38 + w \leq 50\)

Make w the subject

\(w \leq 50 - 38\)

Solving (b): If 9lb and 5lb is added to the bag, will it go overweight?

First, we need to solve the inequality in (a)

\(w \leq 50 - 38\)

\(w \leq 12\)

This means that additional weights must not exceed 12 pounds

Adding 9lb and 5lb, we have:

\(9 + 5 = 14\)

14 pounds is more than 12 pounds.

The answer is: a) yL[n] = 4 - 10 11 5 - 3, b) yC[n] = 4 - 10 11 5, c) use DFT, d) y[n] ≠ yL[n].

a) To finish up the straight convolution yL[n], we convolve the two given groupings including the recipe for direct convolution: yL[n] = sum(g[k]h[n-k]), where the hard and fast is assumed control of all normal likely gains of k. Along these lines, yL[n] = 4 - 10 11 5 - 3, for 0 <= n <= 5.

b) To relax g[n] to a length-4 social event ge[n], we add two zeros to the farthest uttermost ranges of g[n]. We then, process yC[n] including the recipe for circuitous convolution: yC[n] = sum(ge[k]h[(n-k) mod 4]), where the outright is assumed control of all conceivable likely gains of k. Therefore, yC[n] = 4 - 10 11 5 - 3, for 0 <= n <= 3.

c) To finish up yC[n] utilizing the DFT-based approach, we at first register the DFT of g[n] and h[n] utilizing the recipe: G[k] = sum(g[n]exp(- j2pikn/N)) and H[k] = sum(h[n]exp(- j2pikn/N)), where the all out is assumed control of all expected increases of n from 0 to N-1, and N is the length of the groupings. We then, at that point, register the DFT of yC[n] utilizing the recipe: Y[k] = G[k]H[k]. At long last, we secure yC[n] by taking the inverse DFT of Y[k] utilizing the recipe: yC[n] = (1/N)sum(Y[k]exp(j2pikn/N)).

d) To relax g[n] and h[n] to length-6 groupings, we add two zeros to the farthest uttermost compasses of each and every blueprint. We then, process the 6-point circuitous convolution y[n] of the truly lengthy groupings utilizing the condition: y[n] = sum(g[k]h[(n-k) mod 6]), where the total is assumed control of all conceivable likely gains of k. Clearly y[n] isn't equivalent to yL[n], since the backhanded convolution isn't unclear from the prompt convolution when the movements are associated by zero-cushioning.

Step-by-step explanation:

The pig pen is 14 sq. meters larger than the chicken pen built by the former.

Consider a rectangle with length 'L' and width 'W'.

So, its perimeter = 2(L + W) units and area = L × W sq. units.

It is given that a farmer built a rectangular pen for chickens.

The chicken pen's perimeter is 12 meters, and she used only one side of the barn as one length of the rectangular pen.

So,

L + 2W = 12

⇒ L = 12 - 2W

Then its area is calculated as below:

Area = L × W

        = (12 - 2W) W

        = 12W - 2W²

Consider A' = 0 for finding the larger area.

So, differentiating the area w.r.t W,

dA/dW = 12 - 4W

0 = 12 - 4W

⇒ 4W = 12

∴W = 3 meters

Then,

L = 12 - 2W = 12 - 2(3) = 6 meters

So, the area of the chicken pen = 6m × 3m = 18 m²

It is given that,

The length of the pig pen was 2 meters more than the length of the chicken pen. I.e., L' = L + 2

The width of the pig pen was 1 meter more than the width of the chicken pen. I.e., W' = W + 1

On substituting L and W values to find the dimensions of the pig pen,

L' = 6 + 2 = 8m

W' = 3 + 1 = 4m

Then,

Area = L' × W'

        = 8m × 4m

        = 32 m²

Finding how much larger is the pig pen than the chicken pen:

Area of the pig pen - Area of the chicken pen

⇒ 32 m² - 18 m² = 14 m²

Therefore, the pig pen is 14 m² larger than the chicken pen.
