a physicist working in a large labortory has found out that the light particles traveling in a particle accelerator increase velocity in a manner that can be described by linear function -4x+3y=15, where x is time and y is velocity in kilometers per hour. use this function to determine when a certain particle will reach 30 km/hr

Answers

Given:
-4x + 3y = 15
where 
x = time, hr
y = velocity, km/h

Write the equation as
3y = 4x + 15
y = (4/3)x + 5

When y = 30 km/h, then
(4/3)x + 5 = 30

A corporation employs 2000 male and 500 female engineers. a stratified random sample of 200 male and 50 female engineers gives each engineer 1 chance in 10 to be chosen. this sample design gives every individual in the population the same chance to be chosen for the sample. is it an srs? explain your answer.

Answers

Yes, an SRS by definition is a sample that is divided into groups that share an attribute and then those groups are combined. In this case the groups are divided by gender.
Final answer:

No, the sample design is not a simple random sample (SRS), but a stratified random sample. In an SRS, every individual in the population has an equal chance of being chosen for the sample.

Explanation:

The given sample design is not a simple random sample (SRS). In an SRS, every individual in the population has an equal chance of being chosen for the sample. However, in this case, the sample design is a stratified random sample. It involves dividing the population into groups (in this case, male and female engineers) and then selecting a sample from each group using a different sampling rate.

To determine if a sample design is an SRS, we need to ensure that each individual in the population has an equal chance of being chosen, and this probability is the same for every individual. In the case of the given example, the sample design does not meet these criteria, making it not an SRS.

Write the equation of the piecewise function ƒ that is represented by its graph.

check the picture below.

the hole, of course means, that point is not part of the range.

and the closed hole, means it is part of that range.

[tex]\bf f(x)= \begin{cases} \sqrt{x},&x\ \textless \ 4\\ x^2,&x\ge 4 \end{cases}[/tex]

Piecewise function with 3 pieces: [tex]x^2+1, 4x-8, 2[/tex]

The piecewise function ƒ that is represented by the graph in the image is:

ƒ(x) =

[tex]x^2+1, & \text{if } 0 \le x < 4 \\[/tex]

[tex]4x-8, & \text{if } 4 \le x < 5 \\[/tex]

[tex]5^2+1 = 26, & \text{if } x = 5[/tex]

This is because the graph of the function consists of three distinct pieces:

For 0≤x<4, the graph is a parabola with vertex at (0,1) and opening upwards. This suggests that the function is of the form [tex]ax^{2} +bx+c.[/tex]

We can find the values of a, b, and c by substituting the points (0,1), (1,1), and (4,16) into the equation.

This gives us the system of equations:

\begin{cases}

[tex]a \cdot 0^2 + b \cdot 0 + c = 1[/tex]

[tex]a \cdot 1^2 + b \cdot 1 + c = 1 \\[/tex]

[tex]a \cdot 4^2 + b \cdot 4 + c = 16[/tex]

\end{cases}

Solving this system gives us a=1, b=0, and c=1, so the equation of the function for this interval is [tex]x^{2} +1[/tex].  

For 4≤x<5, the graph is a line with slope 4 and y-intercept −8.

This suggests that the function is of the form mx+b.

We can find the values of m and b by substituting the points (4,2) and (5,25) into the equation.

This gives us the system of equations:

\begin{cases}

[tex]4m+b = 2 \\[/tex]

5m+b = 25

\end{cases}

Solving this system gives us m=4 and b=−8, so the equation of the function for this interval is 4x−8.

For x=5, the graph is a horizontal line at y=26.

This suggests that the function is of the form c.

We can find the value of c by simply looking at the graph.

This gives us c=26, so the equation of the function for this interval is 26.

Therefore, the complete piecewise function is:

ƒ(x) =

\begin{cases}

[tex]x^2+1, & \text{if } 0 \le x < 4 \\[/tex]

[tex]4x-8, & \text{if } 4 \le x < 5 \\[/tex]

[tex]5^2+1 = 26, & \text{if } x = 5[/tex]

Think of f(x) as the y value If you add 2 to y you move the function up by 2 units. The shape stays the same, where it is increasing and decreasing stays the same. It's just an upward shift. If f(x) is an even function, this means f(-x) = f(x), so what I just described applies If f(x) is an odd function, this means f(-x) = -f(x), so what I just described applies as as well When you multiply f(x) by -1/2, you invert the function f(x) so that positive values become negative and negative become positive. This means where f(x) was maximum, it's now a minimum and vice-versa If f(x) is even, then what I've just described applies If f(x) is odd, then what I've just described applies Hope this helps.

Taylor bought 200 shares of stock for $18.12 per share last year. He paid his broker a flat fee of $30. He sold the stock this morning for $21 per share, and paid his broker 0.5% commission.

a. What were Taylor's net proceeds?

b. What was his capital gain?

Answers

Taylor's net proceeds from the sale of his stock are $4179, after paying his broker's 0.5% commission. His capital gain on the investment is $525, calculated by subtracting the total purchase cost, including the initial broker's flat fee, from the net proceeds of the sale.

a. What were Taylor's net proceeds?

To calculate Taylor's net proceeds, we need to consider the initial cost of buying the shares, any fees paid to the broker, and the amount earned from selling the shares. Here's the breakdown:

Determine initial cost: 200 shares x $18.12 per share = $3624

Add broker's fee when buying: $3624 + $30 = $3654

Subtract broker's fee when selling: $42 (0.5% of $8400 from selling 200 shares at $21 per share)

Calculate net proceeds: $8400 - $42 = $8358

b. What was his capital gain?

To find Taylor's capital gain, subtract the total cost (initial purchase cost + fees) from the total earnings after selling the shares. The calculation is as follows:

Find the side of a square whose diagonal is of the given measure.
Given = 8 miles

Answers

Final answer:

To find the side of a square with a given diagonal length, apply the Pythagorean theorem. With a diagonal of 8 miles, the side length is calculated to be 4√2 miles.

Explanation:

To find the side of a square whose diagonal is given, we can use the Pythagorean theorem. In a square, the diagonal creates two right-angled triangles, each with the square's sides as the legs.

Let the side of the square be s, and the given diagonal is 8 miles. According to the Pythagorean theorem, the diagonal (d) is calculated as d = √(s² + s²). Simplifying, this becomes d = √(2 * s²) or s = d / √2. Substituting the value of the diagonal, we get s = 8 / √2. To get rid of the radical in the denominator, we can multiply both the numerator and denominator by √2, giving us s = (8√2) / 2, which simplifies to s = 4√2 miles. Therefore, the side of the square is 4√2 miles.

a video store sold 2 vhs tapes for every 4 dvds if 564 dvds were sold how many vhs tapes were sold?

Answers

282 because you divide 564 by 2 i think. Hope this helps

Final answer:

To find the number of VHS tapes sold when 564 DVDs were sold, divide the number of DVDs by 2.

Explanation:

To solve this problem, we can set up a ratio comparing the number of VHS tapes sold to the number of DVDs sold. Since the ratio is given as 2 VHS tapes to every 4 DVDs, we can simplify it to 1 VHS tape to every 2 DVDs. If 564 DVDs were sold, we can divide this number by 2 to find the number of VHS tapes sold:

564 DVDs ÷ 2 = 282 VHS tapes

Therefore, 282 VHS tapes were sold.

Divide 42 in a ratio of 1:2:3?

Answers

Ratio 1:2:3 means we have x, 2x and 3x as the three parts

x+2x+3x = 42
6x = 42
6x/6 = 42/6
x = 7

Since x = 7, this means 2x = 2*7 = 14 and 3x = 3*7 = 21

Dividing 42 into the ratio of 1:2:3 means we have 7:14:21 as the answer

If we divide all three parts of 7:14:21 by the GCF 7, we reduce it down to 1:2:3

Describe a real-world scenario and which it would be important to apply trigonometric ratios or special right triangles.

Answers

Most notable application scenario is civil engineering. Trigonometric calculations are essential when projecting buildings, bridges, parking lots, or pretty much anything that is supposed to be used as a piece of infrastructure. Failure to calculate properly can be disastrous and can even cost people lives if bridges fall or roofs on buildings crash or similar.

Answer:

In forensic science trigonometry can be used to calculate a projectile’s trajectory, to estimate what might have caused a collision in a car accident or how did an object fall down from somewhere, or in which angle was a bullet shot etc.

Electrical engineers also use trigonometry. Modern power companies use alternating current to send electricity over long-distance wires. In an alternating current, the electrical charge regularly reverses direction to deliver power safely and reliably to homes and businesses.

Electrical engineers use trigonometry to model this flow and the change of direction, with the sine function used to model voltage. Every time you flip on a light switch or turn on the television, you’re benefiting from one of trigonometry's many uses.
