Find the value of x that makes lines u and v parallel.

Answer:

Since p(x) is exactly divisible by x – 3, then p(3) = 0.

Plugging in x = 3 into p(x), we get

4(3)2 – 6(3) – m = 0

36 – 18 – m = 0

m = 18

Therefore, the value of m is 18.

Step-by-step explanation:

According to the statement the probability of getting either a head or an even number on the die is 3/4.

To calculate the probability of getting a head or an even number, we can use the formula for the probability of the union of two events:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
In this case, A represents getting a head, and B represents getting an even number on the die.
P(A) = Probability of getting a head = 1/2 (since there are two sides of the coin: heads and tails)
P(B) = Probability of getting an even number on the die = 3/6 (since there are three even numbers out of six possible outcomes: 2, 4, and 6)
P(A ∩ B) = Probability of getting both a head and an even number. Since these two events are independent, we can find this probability by multiplying the individual probabilities: P(A) * P(B) = (1/2) * (3/6) = 1/4
Now, we can find the probability of the union:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = (1/2) + (3/6) - (1/4) = 1/2 + 1/2 - 1/4 = 3/4
So, the probability of getting either a head or an even number on the die is 3/4.

To solve this problem, we need to use algebra. Let x be the number of hours that have passed since Wednesday morning. Then the total snow on the ground on Wednesday morning is 3 inches, and the total snow on the ground at any time x hours later is:

3 + 2x

Similarly, the total snow on the ground on Friday morning is 5 inches, and the total snow on the ground at any time x hours later is:

5 + 1x

To find out when these two totals are equal, we can set the expressions equal to each other and solve for x:

3 + 2x = 5 + 1x

Subtracting 1x from both sides, we get:

2x = 2

Dividing both sides by 2, we get:

x = 1

Therefore, the total snow on the ground would be equal after 1 hour.

Now, We can formulate;

Since, KP = PL

Hence, HP = PJ

Then, Δ PKH ≅ Δ PLJ

By HL property.

As point K, L are midpoint of GH and GJ.

Then, KH ≅ LJ = 1/2(JH)

⇒ LJ = 1/2 (36) = 18 feet

As, GH ≅ GJ

Then,

m GM = 1/2 (1/2 (m GM) = 1/4 (360 - 52) = 77 deg.

As, m ∠QST = 71°,

So, m QT = 2 (m ∠QST) = 2 (71) = 142 deg

m ∠STR = 1/2 (m SR) = 1/2 (46) = 23 deg

As RT is a diameter then,

m ∠TSR = 90°

Then, m ∠SRT = 190 - 90 - m ∠STR

m ∠SRT = 67 deg

Hence, m ST = 2 m ∠SRT = 2 (67) = 134 deg

Since, m ∠RSQ = 90 - 71 = 19 deg

The angle between the normal to the diaphragm and a line to the first minimum in the diffraction pattern is approximately 9.43 degrees

To find the angle between the normal to the diaphragm and a line to the first minimum in the diffraction pattern, we can use the concept of diffraction and the formula for the angle of the first minimum in a single-slit diffraction pattern:

sin(θ) = λ / (diameter)

where θ is the angle, λ is the wavelength of the sound, and the diameter is the diameter of the diaphragm.

First, let's convert the frequency of 15.69 kHz to the corresponding wavelength using the formula:

wavelength = speed of sound / frequency

wavelength = 1450 m/s / (15.69 kHz * 1000 Hz/kHz)

wavelength = 0.09257 meters (rounded to five decimal places)

Next, we can substitute the values into the formula to find the angle:

θ = [tex]sin^{(-1)}[/tex] (0.09257 meters / 0.5806 meters)

θ ≈ 9.43 degrees (rounded to two decimal places)

Therefore, the angle between the normal to the diaphragm and a line to the first minimum in the diffraction pattern is approximately 9.43 degrees. This angle represents the bending or spreading of the sound waves as they pass through the circular hole of the diaphragm, creating the diffraction pattern.

Answer: $0.07 and $0.08

Step-by-step explanation: 1. To find the price per square inch of a 16 inch pizza for $14, we need to first calculate the area of the pizza.

The formula for the area of a circle is A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, which is 8 inches.

So, the area of the pizza is A = π(8)^2 = 64π square inches.

The price per square inch is the total price divided by the area of the pizza:

Price per square inch = Total price / Area

Price per square inch = $14 / (64π) square inches

Price per square inch ≈ $0.07

Therefore, the price per square inch of a 16 inch pizza for $14 is approximately $0.07.

Answer: $0.07

2. Following the same method as above, for a 14 inch pizza for $12, the radius is 7 inches and the area is A = π(7)^2 = 49π square inches.

The price per square inch is:

Price per square inch = Total price / Area

Price per square inch = $12 / (49π) square inches

Price per square inch ≈ $0.08

Therefore, the price per square inch of a 14 inch pizza for $12 is approximately $0.08.

There are two ways you could approach this.

The first is to solve each inequality separately and see which one ends up equal to x ≥ -1.

Another and faster option is to test 0 in each inequality, because 0 is in the solution set and 0 is easy to work with.  (You could do this for any value in the solution set.)

A: Is 4(0) + 3 > 7 true?  No.  3 > 7 is false.  This eliminates A.

B. Is 0/3 - 2 ≥ 2 true?  No.  -2 ≥ 2 is false.  This eliminates B.

C. Is -2(0) - 3 ≤ -1 true?  Yes.  -3 ≤ -1 is false.  We cannot eliminate C.

D. Is 0 + 5 < 4 true?  No.  5 < 4 is false.  This eliminates D.

So based on using x=0, the only possible solution is C.

You can double check this by solving 2x - 3 ≤ -1 for x:

    -2x - 3 ≤ -1

         -2x ≤ 2  (by adding 3 to both sides)

Now when you divide by -2 to solve for x, remember to flip the inequality.

         -2x ≤ 2

             x ≥ -1  

So this confirms that C is correc.

Answer:

6x² + 19x + 15

Step-by-step explanation:

2x(3x+5)+3(3x+5)

= (3x + 5) (2x + 3)

= 6x² + 9x + 10x + 15

= 6x² + 19x + 15

So, the answer is 6x² + 19x + 15

We can start by simplifying the left side of the equation using the distributive property:

2x(3x+5)+3(3x+5) = (2x)(3x) + (2x)(5) + (3)(3x) + (3)(5)

= 6x^2 + 10x + 9x + 15

= 6x^2 + 19x + 15

Now we can compare this expression with the right side of the equation, which is a polynomial in x with unknown coefficients a, b, and c:

ax^2 + bx + c

Since the two sides are equal, their corresponding coefficients must be equal as well. This gives us a system of three equations in three unknowns:

a = 6 (the coefficient of x^2)

b = 19 (the coefficient of x)

c = 15 (the constant term)

Therefore, the solution to the equation 2x(3x+5)+3(3x+5)=ax^2+bx+c is:

2x(3x+5)+3(3x+5) = 6x^2 + 19x + 15

The shot put is in the air for approximately 3 seconds.

The height h (in feet) of the shot put as a function of the time t (in seconds) after it is thrown can be modeled by the equation:

h(t) = h + vt - (1/2)gt²

where v is the initial vertical velocity in feet per second, and s is the initial height in feet.

Here, the initial vertical velocity is 40 feet per second, and the initial height is 5.69 feet. Therefore, we can plug in these values to get:

h = -16t² + 40t + 5.69

To find the time that the shot put is in the air, we need to find the value of t when h = 0, since the shot put will hit the ground when its height is 0.

Therefore, we can set the equation equal to 0 and solve for t:

0 = -16t² + 40t + 5.69

Using the quadratic formula, we get:

t = (-b ± √(b² - 4ac)) / 2a

where a = -16, b = 40, and c = 5.69.

Plugging in these values, we get:

t = (-40 ± √(40² - 4(-16)(5.69))) / 2(-16)

Simplifying, we get:

t ≈ 3 or t ≈ 0.2

Since the shot put cannot be in the air for negative time, the only possible answer is t ≈ 3.
