for the simple harmonic motion equation d=2 sin(pi/3t) what is the period
For the simple harmonic motion equation d=2 sin(pi/3t), the period is 6 seconds.
The period of a simple harmonic motion is the time taken for one complete cycle of the motion. In this equation, d represents the displacement or position of the object at time t. The equation is in the form of sin function with the argument (pi/3)t. The general form of the equation for simple harmonic motion is d=A sin(ωt+φ), where A is the amplitude, ω is the angular frequency, and φ is the phase angle. To determine the period of this motion, we can use the formula T=2π/ω, where T is the period and ω is the angular frequency. In this case, ω=pi/3, so the period is T=2π/(pi/3)=6 seconds (rounded to the nearest second). Therefore, the object completes one full cycle of motion every 6 seconds.

write the point-slope equation of the line that passes through(3,5) and (7,1)
Answer: y - 1 = –(x –7)
or y –5 = –1(x –3)
The attachment shows the graph of these equations (identical)
Step-by-step explanation:
The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
To find the slope, m, use the given coordinates. Get the difference in the y-values and divide by the difference in the x-values. This is "rise over run."
Subtract the first coordinate from the second coordinate.
Given coordinate points: (3,5) and (7,1) substitute values:
m= 1 –5 / 7 –3 becomes m= –4/4 so the slope, m = –4/4
That is –1 The "1" is "understood," so only the negative sign represents the slope in the equation
To write the equation: Take the basic form, substitute b and a values from either given coordinate. And use the value of m we just calculated.
y - b = m(x - a) Using the second coordinate: (7,1)
y - 1 = –(x –7)
or using the first coordinate:
y –5 = –(x –3)

Answer:
Danielle is 7 and her counselor is 21
Step-by-step explanation:
Let x be the age of Danielle and y be the age of her counselor then:
y=3x
x+y=28
We can solve this using substitution. In this case, substitute 3x for y since y=3x...
x+3x=28
4x=28
Divide both sides by 4 (division property of equality)

Step-by-step explanation:
Find the coordinates of the point on a circle with radius 16 corresponding to an angle of \frac{5\Pi}{9}. If your answer is not an integer then round it to the nearest hundredth.
To find the coordinates of the point on a circle with radius 16 corresponding to an angle of \frac{5\Pi}{9}, follow these steps:
1. Convert the angle to radians, if not already given. In this case, the angle is already given in radians as \frac{5\Pi}{9}.
2. Recall that the parametric equations for a circle with radius r and angle θ are:
x = r * cos(θ)
y = r * sin(θ)
3. Plug in the radius and angle into these equations:
x = 16 * cos(\frac{5\Pi}{9})
y = 16 * sin(\frac{5\Pi}{9})
4. Calculate the values of x and y, then round them to the nearest hundredth:
x ≈ 5.88
y ≈ 14.43
5. Write the coordinates as an ordered pair: (5.88, 14.43).
Therefore, the coordinates of the point on the circle with radius 16 corresponding to an angle of \frac{5\Pi}{9} are approximately (5.88, 14.43).

Brian has 64 water bottles for the 5K race participants. In addition, he is planning to buy some boxes of water bottles that have 14 water bottles each. All of the boxes cost the same. Brian can buy up to 5 water bottles given the amount of money he has. Let x represents the number of boxes of water bottles Brian buys. Write a function rule to describe how many water bottles Brian will have based on the number of boxes he buys. Find a reasonable range for the function.
Answer:
f(x) = 14x + 64
{64, 78, 92, 106, 120, 134}
Step-by-step explanation:
0, 1, 2, 3, 4, 5 The domain is the number of boxes of water bottles Brian can buy.
A reasonable range for the function is {64, 78, 92, 106, 120, 134}.
Answer:
f(x) = 14x + 64
{64, 78, 92, 106, 120, 134}
Step-by-step explanation:
Identify the independent and dependent variable.
Independent variable: x = number of boxes of water bottles Brian buys
Dependent variable: f(x) = the total number of water bottles
Write the function rule.
f(x) = 14x + 64 Add 64 water bottles to 14 times the number of boxes Brian buys to get the total number of water bottles.
Identify reasonable domain values.
0, 1, 2, 3, 4, 5 The domain is the number of boxes of water bottles Brian can buy.
Calculate f(x) for each value of x.
f (0) = 14(0) + 64 = 64
f (1) = 14(1) + 64 = 78
f (2) = 14(2) + 64 = 92
f (3) = 14(3) + 64 = 106
f (4) = 14(4) + 64 = 120
f (5) = 14(5) + 64 = 134
A reasonable range for the function is {64, 78, 92, 106, 120, 134}.
Chicos estoy en un aprieto ayudarme pls Sabiendo que una falda es 5 € más cara que una blusa y que si compro 6 faldas y 4 blusas pago 480 €, ¿cuánto vale la falda?
Answer:
El precio de la falda es 50 €.
Step-by-step explanation:
Lo que sabemos:
\( F = 5 + B \) (1)
En donde F es por falda y B por blusa.
Si compras 6 faldas y 4 blusas y pagas 480 €:
\( 6F + 4B = 480 \) (2)
Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.
\( 6F + 4B = 480 \)
\(6(5 + B) + 4B = 480\)
\( 10B = 480 - 30 \)
\(B = \frac{450}{10} = 45\)
Finalmente, el precio de la falda se puede encontar con la ecuación (1):
\(F = 5 + 45 = 50\)
Por lo tanto, el precio de la falda es 50 €.

Answer:
Each small ice sculpture costs $79 and each large one costs $134
Step-by-step explanation:
3 small + 4 large = $773
2 small + 4 large = $694
3 - 2 = 1
$773 - $694 = $79
So one small = $79
$79 x 3 = $237
$773 - $237 = $536
$536 / 4 = $134
So one large = $134
Answer:
The cost of a small ice sculpture is $79 and the cost of a large ice sculpture is $134.Step-by-step explanation:
Let's say L for 'Large ice sculpture' and S for 'Small ice sculpture'.
We know that:
3S + 4L = 7732S + 4L = 694Work:
3S + 4L = 7732S + 4L = 694
=> 3S - 2S = 773 - 694=> S = 79This means that one small ice sculpture will cost $79. Let's substitute the value of S into the first equation to find out the value of L.
3S + 4L = 773=> 3(79) + 4L = 773=> 237 + 4L = 773=> 4L = 773 - 237=> 4L = 536=> L = 536/4=> L = 134Hence, the cost of a small ice sculpture is $79 and the cost of a large ice sculpture is $134.

There is a proportional relationship between the weight and total cost of a bag of cherries. One bag weighs 2.1 pounds and costs $7.98. Another bag weighs 2.8 pounds and costs $10.64.
Describe how you would graph the proportional relationship. (4 points)
( I keep getting answers that make no sense so sorry for the spam.)
Step-by-step explanation:
you need to have or create a coordinate grid with x and y coordinate axis (crossing each other at a right angle in the center).
you got 2 data points (2 bags of cherries with their weight and price).
a proportional (or linear) relationship is graphed as a straight line that goes through these 2 points.
the x axis (left-right) stands for the weight, the y-axis (up-down) stands for the price.
we see, when the weight goes up by 0.7 pounds (from 2.1 to 2.8), the price goes up by $2.66.
the slope of the line is
y-diff / x-diff = 2.66/0.7 = 3.8 = 38/10 = 19/5
the general equation of a line is
y = ax + b
a being the slope, b being the y-intercept (the y-value when x = 0).
we know now
y = 19/5 x + b
we use the coordinates of one point to get b :
7.98 = 19/5 × 2.1 + b = 7.98 + b
b = 0
our line equation is therefore
y = 19/5 x
since the original data coordinates are not nice numbers for a grid of whole numbers, let's find now 2 good points to mark on the grid and draw the line.
one point : x = 0. that gives us y = 0. so, (0, 0).
another point : x = 5. that gives us y = 19.
so, mark the points on your coordinate grid
(0, 0) means x = 0, y = 0 (the point where the 2 coordinate axis cross).
(5, 19) means x = 5, y = 19. or if you don't have that much space in the y direction, we can divide both coordinates in half (we can do that because this is proportional or linear) and get
(2.5, 9.5), and you mark this point instead (you can mark half-units with sufficient accuracy).
and then you draw a line through both points (extending beyond the points).

18.64 ft
18.84 ft
Answer:
18.84 ft
Step-by-step explanation:

The circumference of the rug is 18.84 feet, so the correct option is the last one.
What is the circumference of the rug?The circumference of a circle of radius r is given by:
\(C = 2*3.14*r\)
Where 3.14 is pi, as the problem says.
In this case, we know that the radius is equal to 3ft, then we can replace r by 3ft in the above equation:
\(C = 2*3.14*(3ft) = 18.84ft\)
Then we conclude that the circumference of the rug is 18.84ft, so the correct option is the last one.

An Arrow-Debreu security pays $1 at expiry node (6,2). The upstate risk neutral probability is π=0.4 and the return over one time-step is R=1.05. What is the premium of this Arrow-Debreu security?
The value of the Arrow-Debreu security is calculated as the present value of its expected payoff, discounted at the risk-neutral rate. As a result, the premium of the Arrow-Debreu security can be computed using the following formula: \($P_{t}=\frac{1}{(1+R)^{n-t}}\times \pi$,\)
where π=0.4, R=1.05, n=6, and t=2 (expiry node).
By substituting the values, we obtain:
\($P_{2}=\frac{1}{(1+1.05)^{6-2}}\times 0.4 = \frac{0.4}{(1.05)^4} \approx 0.3058$.\)
Therefore, the premium of the Arrow-Debreu security is approximately $0.3058.
Arrow-Debreu securities are typically utilized in financial modeling to simplify the pricing of complex securities. They are named after Kenneth Arrow and Gerard Debreu, who invented them in the 1950s. An Arrow-Debreu security pays $1 if a particular state of the world is realized and $0 otherwise.
They are generally utilized to price derivatives on numerous assets that can be broken down into a set of Arrow-Debreu securities. The value of an Arrow-Debreu security is calculated as the present value of its expected payoff, discounted at the risk-neutral rate. In other words, the expected value of the security is computed using the risk-neutral probability, which is used to discount the value back to the present value.
The formula is expressed as:
\($P_{t}=\frac{1}{(1+R)^{n-t}}\times \pi$\),
where P_t is the price of the Arrow-Debreu security at time t, π is the risk-neutral probability of the security’s payoff, R is the risk-free rate, and n is the total number of time periods.However, Arrow-Debreu securities are not traded in real life. They are used to determine the prices of complex securities, such as options, futures, and swaps, which are constructed from a set of Arrow-Debreu securities.
This process is known as constructing a complete financial market, which allows for a more straightforward pricing of complex securities.
